CULTIVATING COMMON GROUND: Water Use Efficiency Grants

Water Use Efficiency Grants: Beneficial or Double Jeopardy for California Farming? Or both?

 

By Patrick Cavanaugh, Farm News Director

 

Through a competitive joint pilot grant program, the Agricultural Water Use Efficiency and State Water Efficiency and Enhancement Program, the California Department of Water Resources (DWR) and the California Department of Food and Agriculture (CDFA) jointly intend to demonstrate the potential multiple benefits of conveyance enhancements combined with on-farm agricultural water use efficiency improvements and greenhouse gas reductions.

The grant funding provided in this joint program is intended to address multiple goals including:

  • Water use efficiency, conservation and reduction
  • Greenhouse Gas Emissions Reduction
  • Groundwater Protection, and
  • Sustainability of agricultural operations and food production
Agricultural Water Use Efficiency & State Water Efficiency and Enhancement Program – DWR/CDFA Joint RFP Public Workshops

Agricultural Water Use Efficiency & State Water Efficiency and Enhancement Program – DWR/CDFA Joint RFP Public Workshops

Are these competitive grants promoted by DWR and CDFA providing financial support for further compliance or insulting to farmers who have already met and exceeded these stockpiling regulations? Or both?

I would like to address each goal, one by one.

Water Use Efficiency

I challenge DWR and CDFA to find one California farmer who is using water inefficiently or without regard to conservation. Grant or no grant, many farmers in the state have lost most of their contracted surface water deliveries due to the Endangered Species Act, which serves to save endangered species, an important goal we all share, but does so at any cost.

In addition, DWR is now threatening to take 40 percent of the surface water from the Tuolumne River and other tributaries of the San Joaquin River from February 1 to June 30, every year, to increase flows to the Delta to help save the declining smelt and salmon. This will severely curtail water deliveries to the Modesto Irrigation District (MID) and Turlock Irrigation District (TID)—population centers as well as critical farm areas.

MID TID Joint LogoThis proposal, which disregards legal landowner water rights and human need, would force MID and TID to dedicate 40 percent of surface water flows during the defined time period every year, with no regulatory sunset, for beneficial fish and wildlife uses and salinity control. The proposal disregards other scientifically acknowledged stressors such as predatory nonnative non-native striped bass and largemouth bass, partially treated sewage from Delta cities, and, according to the Bay Delta Fish & Wildlife Office of the U.S. Fish & Wildlife Service Pacific Southwest Region, invasive organisms, exotic species of zooplankton and a voracious plankton-eating clam in the Delta from foreign ships that historically dumped their ballast in San Francisco waters.

While many farmers have fallowed their farmland, other farmers across the state have resorted to reliance on groundwater to keep their permanent crops (trees and vines) alive. The new DWR proposal to divert 40 percent of MID and TID surface water will force hundreds of growers in this region—the only groundwater basin in the Valley that is not yet critically overdrafted—to use more groundwater. 

In a joint statement, MID and TID said, “Our community has never faced a threat of this proportion. MID and TID have continued to fight for the water resource that was entrusted to us 129 years ago.”

The deadline for submitting public comments is September 30, 2016.

Greenhouse Gas Reduction

Have regulators forgotten Assembly Bill (AB) 32, the Global Warming Solutions Act of 2006, that requires the state to reduce its greenhouse gas emissions by 25 percent (back to 1990 levels) by 2050? Ag is already accommodating this regulation.

U.S. Greenhouse Gas Emissions (Source: EPA) https://www.epa.gov/ghgemissions/sources-greenhouse-gas-emissions

U.S. Greenhouse Gas Emissions (Source: EPA)

Now Governor Brown has signed SB-1383, “Short-lived climate pollutants: methane emissions: dairy and livestock: organic waste: landfills” into law that mandates a 25 percent reduction in methane emissions from cow burps, flatulence and manure from all dairy cows and other cattle to achieve the 1990 statewide greenhouse gas emissions level by 2020.

Now CDFA and DWR are asking for grant requests to reduce greenhouse emissions even further. Really?

The deadline for submitting public comments is September 30, 2016.

Groundwater Protection

Ironically, farmers want to reduce their groundwater needs because groundwater has always functioned in the state as a water savings bank for emergency use during droughts and not as a primary source of irrigation. But massive non-drought related federal and state surface water cutbacks have forced farmers to use more groundwater.

Golden State farmers are doing everything possible not to further elevate nitrates in their groundwater. Some nitrate findings left by farmers from generations ago are difficult to clean up.

But the DWR and CFA grant wants California agriculture to do more!

The deadline for submitting public comments is September 30, 2016.

Sustainability of Agricultural Operations and Food Production

Virtually, no one is more sustainable than a multi-generational farmer. Each year, family farmers improve their land in order to produce robust crops, maintain their livelihoods, enrich the soil for the long term, and fortify the health and safety of their agricultural legacy for future generations.

California farmers will continue to do all they can to improve irrigation methods and track their crop protection product use.

And so, I ask again, is this beneficial or double jeopardy for California farming? Or both?

The deadline for submitting public comments is September 30, 2016.

Eighteen New California Farm Academy Graduates!

Eighteen New Farmers Graduate from California Farm Academy

 

By Patrick Cavanaugh, Farm News Director

 

The California Farm Academy, a part-time, seven-month, beginning farmer training program run by the Land-Based Learning, graduated 18 new farmers on Sunday, September 18, 2016.

 

With more than 250 hours of classroom and field training behind them, these enterprising graduates were honored by notables such as Karen Ross, secretary, California Department of Food and Agriculture (CDFA); Craig McNamara, president and owner of Sierra Orchards, as well as president of the California State Board of Food and Agriculture; Sri Sethuratnam, director, California Farm Academy (CFA); and Mary Kimball, executive director, Center for Land-Based Learning, based in Winters California.

new farmers graduate from California Farm Academy beginning farmer training program run by the Land-Based Learning.

Eighteen new farmers graduated from California Farm Academy’s beginning farmer training program run by the Center for Land-Based Learning.

 

“The impetus of our program,” said Christine McMorrow, director of development for Land-Based Learning, “is the need for more farmers as the current ones age out. According to the USDA, over 700,000 new farmers will be needed in the next 20 years to replace those who retire.

 

CFA teachers, farmers, academic faculty and staff, and agricultural, natural resource and business professionals, teach CFA students basic production agricultural practices; crop planning; soil science; pest management; organic agriculture; irrigation and water management; marketing; ecology and conservation; obtaining loans, insurance and permits; farm financials; human resource management; risk management; farm safety; regulatory compliance and problem-solving.

 

McMorrow stated, “These folks have been with us since February, following a rigorous application process. A lot of these folks either have land they have dreamed of farming but did not know how to put it into production. Some of them come from farming families, but they wanted to get involved in the family business on their own. They may have been in a different career and now want to do something new or different. Perhaps they haven’t studied agriculture or they have not seen much agriculture other than what their family does, so this is an opportunity for them to learn and to explore a new business idea.

 

“We only take people who are serious about production agriculture. This is not a program for somebody who thinks, ‘I’ve got an acre in my backyard and I really want to grow something.’ While that’s a cool thing to do, the academy is not for those people.”

 

“Our graduating farmers, who range in age from their late 20s to early 50s, each wrote a business plan and presented it to folks within the agriculture industry,” said McMorrow. “They also planted some of their own crops on a farm in Winters.

 

McMorrow elaborated, “These new farmers have been able to create their own networks, having made contact with more than 40 different folks within the agricultural industry throughout the time they spent with us. These networks include local farmers around Yolo County, Solano County, Sacramento County, and other regions, and will help our graduates realize their dreams.”

 

California Farm Academy (CFA) We grow farmers

“This is the fifth class that has graduated,” explained McMorrow, “and mind you, these folks are doing lots of different things. Some of them already have their own land, some are going to work for someone who has land, some will work other farmers, and some will go into a food-related business.”

 

“Still others will stay and lease small plots of land from us,” McMorrow commented, “to start their own farming business. Beginning farmers face huge barriers to getting started, the biggest of which is access to land, capital and infrastructure. So, to get their farming businesses started, California Farm Academy alumni are eligible to lease land at sites in West Sacramento, Davis and Winters at a very low cost.”

The Center for Land-Based Learning exists to cultivate opportunity.

For the land.

For youth.

For the environment.

For business.

For the economy.

For the future of agriculture.

BREAKING NEWS: Historic Monterey County Farmworker Safety Initiative

BREAKING NEWS

Ag Commissioner & Farmworker Advisory Committee Announce Historic Pesticide Initiative for Farmworker Safety

 

Monterey County Agricultural Commissioner, Eric Lauritzen and the Farmworker Advisory Committee, formed with the assistance of the Center for Community Advocacy (CCA), announced an historic initiative TODAY aimed at providing additional pesticide protections for farmworker safety. The initiative launches a pilot program with leading growers to enhance worker notification through warning signs when pesticides are used in the fields.

 

“California has the toughest farm pesticide restrictions in the nation, and Monterey County already imposes local rules that further protect farmworkers,” said Lauritzen at TODAY’s press conference. “But we are going to do even more to communicate our commitment to safety in the fields.”

 

“We are excited about this initiative that adds an additional element of protection for farmworkers by providing the time and date when it is safe to reenter the fields that require posting,” said Lauritzen. “Farmworkers are the backbone of Monterey County’s $4.8 billion Ag industry, and they are entitled to the highest standard of pesticide safety.”

 

Eric Lauritzen, Monterey County Ag Commissioner

Eric Lauritzen, Monterey County Ag Commissioner, speaking at Press Conference TODAY on Historic Farmworker Safety Initiative

Intended to protect farmworkers, the initiate “has created a relationship between our office, the regulators and the farm worker community,” said Lauritzen. “And it’s really building trust and confidence with our office and the regulatory program there to protect farmworkers,” noted Lauritzen.

 

Additionally, every farmworker in Monterey County (approximately 50,000) will receive a business-card-sized information card (in Spanish) advising them to call the Agricultural Commissioner’s Office if they suspect violations of safety rules. The cards also advise employers that it is illegal to retaliate against farmworkers who seek the help of the Agricultural Commissioner’s Office.

 

The information card reads:

If you have questions or complaints on pesticides, the Monterey County Agricultural Commissioner’s Office will help.

The card includes phone numbers and advises workers that state law also protects them against retaliation if they report a pesticide problem.

 

Currently, regulations for posting pesticide warning signs do not require information indicating the date or time when it is safe for farmworkers to re-enter the fields. The pilot program will include the addition of one sign that will be prominently marked with a red flag and include the date and time that the law allows workers to safely reenter the field. Only the grower or his/her officially designated representative may remove the signs, after first showing the crew leader proof that the re-entry restrictions have expired.

 

Osvaldo Cisneros, a lettuce worker and member of the Farmworker Advisory Committee, feels that the change is very important. “Some farmworkers have been showing up for work and have been told by their mayordomos (supervisors) to re-enter fields even though warning signs are still up,” said Cisneros. “They have to depend on the word of the mayordomos even though they have no way to verify what they are told. This change will allow farmworkers, themselves, to tell when it is safe to enter fields.”

 

The posting and information card initiatives were developed in cooperation with the Farmworker Advisory Committee, a group formed jointly by Lauritzen and the non-profit Center for Community Advocacy. “Many farmworkers are unaware of their right to a safe working environment,” said CCA Executive Director Juan Uranga. “That’s why it is important to provide farmworkers with the information they need to both protect themselves and also gain access to the agencies, like the Monterey County Agricultural Commissioner’s Office, that exist to protect them.”

 

A second member of the Farmworker Advisory Committee, Maria Elena Andrade, added: “It is important for our community to know that the Agricultural Commissioner’s Office exists to serve us, as well as the other parts of the agricultural industry. We are trying to create that message through the Farmworker Advisory Committee, even as we work with the Ag Commissioner and his staff to improve safety for farmworkers.”

 

Growers involved with the initiative include Sea Mist Farms, Tanimura & Antle, Bayview Farms, Scheid Vineyards and Costa Family Farms. Lauritzen recognized these leading growers for their, support, innovation and dedication in their effort to provide additional protections for farmworkers.

 

Lauritzen briefed officials at the state Department of Pesticide Regulation (DPR) on the pilot warning sign program and the information card campaign. DPR Director Brian Leahy praised the Monterey County initiative. “We all know that farmworkers are the most vulnerable population in terms of potential exposure to pesticides,” said Leahy. “When we protect farmworkers more effectively, we also enhance protection for the environment and the community at large. This initiative represents an important step forward for farmworker safety, and it underscores California’s leadership in environmental protection.”

Historic Note:

The accord reached two years ago between the Office of the Monterey County Agricultural Commissioner, the agency that oversees pesticide regulations and other worker safety matters, and the Center for Community Advocacy (CCA), a farmworker advocacy group, established the Farmworker Advisory Committee for the Office of the Agricultural Commissioner of Monterey County—the first of its kind in the State Of California.

Jasieniuk on Weed Evolution

Tracking Herbicide Resistance in Weed Evolution  

By Emily McKay Johnson, Associate Editor

 

Marie Jasieniuk, professor and weed scientist at UC Davis College of Agricultural and Environmental Sciences, discussed her groundbreaking research, “I work on the population genetics and evolution of agricultural weeds and invasive plants,” she said. “We use molecular tools to look at the origins and spread of weeds. We also use molecular tools and genetic studies to understand the evolution of herbicide resistance in weeds,” Jasieniuk added, “to be able to propose management approaches that reduce the likelihood of further evolution and spread of resistant weeds.”

UC Davis Annual Weed Day 2016

UC Davis Annual Weed Day 2016

Jasieniuk and her team identify the origins of invasive plants, and determine how they were introduced. “We study how they were introduced, how they have spread and whether they have been introduced multiple times. Again, if we understand how they’re spreading, we can do something to try to stop the spread,” she said.

Italian rye grass, a weed Jasieniuk is currently studying, is problematic because it is resistant to Roundup, a popularly used weed and grass killer by growers. “UC ANR Cooperative Extension specialist, now emeritus, Tom Lanini, and I sampled over 100 locations of Italian rye grass and tested them for resistance to Roundup ten years ago,” she said about the project, funded by USDA. “Last year, we re-sampled all of those sites, and we’re re-testing to see if there’s been an increase or a decrease or no change in resistance to glyphosate, to Roundup,” she said.

Roundup isn’t the only weed and grass killer available on the market. “We’re looking at resistance to three other herbicides,” she said. Working with growers to determine the most efficacious weed treatments that also reduce the likelihood of wood resistance to herbicides,” Jasieniuk explained, “We interview growers about their herbicide use, non-chemical approaches, and integrated management techniques to identify management practices that correlate highly with low or no resistance,” she explained.

Resistance management is found to be more effective with a rotation of various herbicides. “What you want to do is rotate different types of herbicides with different modes of action,” Jasieniuk said. “Perhaps do tank mixes and incorporate non-chemical approaches as well,” she added.

Eliminating weeds can be as simple as disking and digging them out with a shovel when there are only a few. “I think, in many cases, this would have done a lot to prevent new weeds from coming in and certainly resistant weeds from spreading,” she noted.

Timorex Gold, Broad-spectrum Biofungicide

Biofungicide Timorex Gold to Help Western Vegetable Growers Fight Disease Pressure

By Patrick Cavanaugh, Farm News Director

The U.S. EPA has approved Timorex Gold, a new broad-spectrum reduced-risk biopesticide that is already a leading biofungicide in Latin America to control black sigatoka, a leaf-spot fungal disease on bananas, for various domestic crops such as tomatoes, strawberries, as well as other berries, cucurbits, grapes, tree nuts, and lettuce.

Stockton photo Strawberries & Blueberries beautiful!Timorex Gold is well positioned for American crops because it is known to be effective on powdery mildew and Botrytis on strawberries and tomatoes, plus bacterial blight on tomatoes.

Sarah Reiter, country manager of STK Stockton, an innovative Israeli company that opened its U.S. headquarters in Davis, CA. “We are very excited about the products performance we are seeing in areas where it is registered,” said Reiter. “We are happy with the label the EPA granted us. We still await registration in California and anticipate it next year or possibly late this season.”

Reiter noted the highly effective active ingredient in Timorex Gold, the plant extract Meluleuca alternifolia, or tea tree oil, gives growers a powerful new tool to control both bacteria and fungi diseases. “We know growers do not have a lot of choices for bacterial control,” said Reiter, “so any new active ingredient is a good thing. This product has the added bonus of being a fungicide too.”

“Timorex Gold has been established as a primary control product for sigatoka because it performs so well,” Reiter commented. “Growers use it because of its profile, and it’s easy to use. And while the product is a biopesticide, once the growers get it in their hands, they tend to forget it’s a biopesticide because it performs as if it is a synthetic material.”

timorexgold STK Stockton Group“As an industry we have been looking for this for quite a long time,” Reiter reflected. “While biologics have been around for a century, historically, growers would have to give up some levels of control in order to implement them into a conventional program. We do not see that loss when using Timorex Gold against sigatoka disease.”

“Our expectation in the U.S. is that growers will see that same high level of performance when they use the product here,” Reiter said. “And since Timorex Gold is a biological, there is no concern for Maximum Residue Level (MRL) data because there is no residue on the crop. The product will have very short re-entry intervals (REIs) and preharvest intervals (PHIs), as well as flexible application intervals, a strength that growers like because it gives them a lot of flexibility to implement the product into their program when they need to instead of having to manage REIs and PHIs.”

In addition, Timorex Gold has a very low designation of FRAC 7¹, which means the product has a unique mode of action that can be used in alternate succession with other fungicide modes of action to prevent the development of resistance.

Concurrently, STK Stockton continues to invest heavily in its new technology pipeline with the intention of bringing more innovative biopesticides into different markets. As part of these efforts, the company has recently announced the appointment of Shay Shaanan as the new vice president R&D, leading the company’s activities. The former global development manager of the fungicides division at ADAMA (formerly Makhteshim Agan), Shaanan has over 15 years of experience in research and commercialization of crop protection products.

“Having Shay join our team marks another significant milestone in our growth strategy. It reflects our commitment to advance our technologies and provide the agriculture industry with new solutions for sustainable agriculture.” explained Guy Elitzur, CEO of STK Stockton. “Shay will lead our R&D and will be of enormous value in moving our company forward. Additionally, we will be looking for in-licensing partners, including bio companies in the U.S. to broaden our product offerings.” said Elitzur.

The products of Stockton will be sold under the Syngenta brand for Botrytis and Powdery Mildew in ornamentals globally. The biofungicide technology complements the comprehensive fungicide portfolio of Syngenta and will help to provide its customers with innovative sustainable tools for disease resistance management.

“We are very excited about this agreement,” Elitzur commented, “as Syngenta is the perfect partner for our new products in ornamentals.”

New IPM Work on Brown Stink Bug

New IPM Approach to Brown Stink Bug In Desert Cotton

By Patrick Cavanaugh, Farm News Director

This year, the UC Division of Agriculture and Natural Resources, Cooperative Extension, Riverside County began an Integrated Pest Management (IPM) program to control Euschistus servus, or brown stink bug, a problem in Southern California’s cotton production areas.

Vonny Barlow

Vonny Barlow, a UC Cooperative Extension farm advisor in Riverside County

Vonny Barlow, a UC Cooperative Extension farm advisor in Riverside County began evaluating brown stink bug in cotton last year, and he received additional funding this year from a National Institute of Food and Agriculture (NIFA) grant administered through North Carolina State University, to continue his research this year. Barlow just hired two interns to work with brown stink bug in the Palo Verde Valley in Southern California.

The pest was known to exist in Arizona for about eleven years, but was not a critical issue until about three years ago, when it moved into California. California cotton growers had to spend a lot of money to spray to manage the insect, and it just wasn’t economically feasible.

“In many areas in the south, the brown stink bug pierces into the cotton boll with its proboscis-like mouthpart—a stiff, short straw,” said Barlow. “Once the cotton boll is pierced, the brown stink bug tries to feed on the cotton seed. The problem is the puncture allows bacteria to enter and boll rot to set in. Boll rot is the issue because it lowers yield quality; without boll rot, the brown stink bug is much more of a manageable pest.”

Spraying is not the answer to control the bug, according to Barlow. “We are going to look at an area-wide pest management approach by just essentially surveying the pest control advisers (PCAs) and growers about cropping that is near or even some miles away from cotton,” he said. “Where is the brown stink bug showing up? When did it show up? Is it moving? When are you going to harvest? Is it moving into the cotton? That way, we can give the cotton growers a better idea of when they should start management practices for brown stink bug, instead of just routinely calendar-spraying every two weeks.”

“We hope to predict when brown stink bug will move into cotton. Farmers who just harvested wheat should expect it will come into your field within the week. Start scouting; it is another very good IPM tactic to reduce sprays and to better manage pests,” said Barlow.

BREAKING NEWS: First ACP Found In Monterey County

First ACP Found In Monterey County

By Patrick Cavanaugh, Farm News Director

An Asian Citrus Psyllid (ACP) has been found in Monterey County, thus expanding the ACP Quarantine in the state. This is breaking news as the ACP vectors or has the ability to carry a fatal citrus bacterial disease known as Huanlongbing (HLB) or citrus greening.

Save our citrus from citrus greening

“It was in a residential area of northeast Salinas,” said Bob Roach, assistant ag commissioner for Monterey County, “and it’s not really unexpected because, with the exception of Santa Cruz County, we are surrounded by other counties where ACP have been identified on the sticky traps.”

This ACP find was in a residential yard, just north of Salinas. “The most likely cause,” said Roach commented, “When you find it in a residential area, the likely source of the introduction is when people move plants around” from other regions where the psyllid is present.

The California Department of Food and Agriculture (CDFA) will begin the trapping next week,” Roach explained. “They flood the area with traps and then take care of the treatments.” CDFA will coordinate spray programs within 800 meters from the find. “They’re all set up for that,” said Roach.

The Fight Against the Asian Citrus Psyllid

California Citrus Mutual on the Fight Against the Asian Citrus Psyllid and HLB

By Laurie Greene, Editor

On Saturday, June 4, 2016, Patrick Cavanaugh, California Ag Today’s farm news director, hosted iHeart Media’s Ag Life Weekend show on “Power Talk 96.7 FM Fresno and 1400 AM Visalia stations, sitting in for broadcaster Rich Rodriguez. Cavanaugh’s invited guests included Alyssa Houtby, director of public affairs, and Chris Stambach, director of industry relations for the Exeter-based California Citrus Mutual, to discuss the status of the state’s citrus industry amidst the ACP and HLB Infestation.Ag Life Weekend

The Asian Citrus Psyllid (ACP), certainly the number one pest for California citrus, can spread a bacterium known as Huanglongbing (HLB) that is fatal to citrus trees. As of 2016, 22 trees in the state have been infected with the fatal disease and had to be destroyed. The entire citrus industry of California has been and continues to be concerned that the ACP could take down the citrus industry, as it has in Florida.

Alyssa Houtby explained that the fight against ACP in California “is going well, we hope. The Florida citrus industry has been completely decimated by HLB; an estimated 90 percent of their acreage is infested with this disease.”

“Here in California,” Houtby continued, “we saw it crop up in residential citrus before we saw it in commercial citrus. All of the HLB finds, to date, have been in the Los Angeles Basin.” Houtby said they are working diligently to keep the psyllid population down to decrease the exposure of trees to HLB.

The California citrus industry spends approximately $15 million annually on an ACP assessment program, which includes extensive public outreach. Part of the research entails trapping the pest, conducting survey work in the regions in question, applying treatments in residential areas, and managing a delimitation survey around the area of Los Angeles where the disease has populated.

“That means that we’re scouting very consistently,” explained Houtby, “looking for other trees with the disease and pulling those trees out as soon as we find them. We are doing everything we can here in California to keep the pest and disease from spreading—now that we have it,” she noted.

Alyssa Houtby, director of public affairs, California Citrus Mutual

“The California industry has always been one to use a proactive approach,” Houtby elaborated. “We saw what happened in Florida, and we realized really early on that we couldn’t stand by and wait for this disease to find us. We had to actively go look for it and find it—before it found commercial citrus—and we’ve done that.” Regarding the 22 trees in the state that have been destroyed thus far, Houtby said, “It could be a lot worse if we weren’t as proactive as we are.”

When locating a positive ACP find in a residential area, Houtby noted, generally speaking, homeowners have mostly been compliant. “There are pockets in this state where folks don’t like government coming in, knocking on their door and asking to spray their trees with pesticides. We understand that. It’s an opt-in/opt-out scenario here. We’re not forcing homeowners in most cases to treat their trees.”

Chris Stambach

Chris Stambach, director of industry relations for California Citrus Mutual

“But that’s a different situation if HLB is present,” she emphasized. “Then we do. We get a warrant, and we go in and treat the surrounding trees. If we’re treating in response to an ACP find, homeowners can opt out, but overwhelmingly, they don’t. They support our program. They understand that citrus is a part of the California heritage, they like their citrus trees, and they want to keep them in their yards. They understand that the alternative to not treating is that tree will eventually die if it becomes infected. We’ve worked really hard to communicate to the general public about the seriousness of this issue. We’re pleased with the results.” Houtby said.

Chris Stambach discussed the importance of homeowners having a general understanding of the ACP, so if they find something unusual in their citrus tree, they know to call the local ag commissioner.

Stambach detailed ACP and HLB specifications to increase homeowners’ understanding about their beloved citrus trees. “HLB is symptomatic, but it takes a long time for those symptoms to show up in the tree,” said Stambach. “You really have to know what you’re looking for because some fertilizer deficiency issues in the tree will mimic what HLB looks like.”

“Though the ACP is a really tiny little bug, there are some key signs the public can look for,” explained Stambach. “You want to look for that psyllid and the little tubules it excretes on the new flush of growth—pretty much right there at the end of the terminals where all that new growth comes in the springtime and in the fall. That’s key to California, because there are only certain times of the year when that ACP is actively feeding on the citrus tree.”

California has a real benefit over the Sunshine State, where they have to spray 12 times a year to keep the psyllids at bay. “It hasn’t been effective for [Florida],” noted Stambach. “We had a couple of growers out this last winter to our Citrus Showcase. They planted new trees, 4 years old, and although they spray 12 times a year, their orchards are 100% infected with HLB. That’s the devastation that this insidious disease can bring. It’s really difficult to get your hands around it because it takes so long to be able to detect it.”

Another benefit for California citrus, according to Houtby, is, “We have a lot of areas in the state where we don’t have to spray at all because we can use beneficial insects. That’s just the great part about farming in California.”

Houtby and her team often look to Florida for ideas and recommendations on what has worked for them, what hasn’t and what citrus growers here can do to prevent the disease from taking hold of their citrus. She clarified that 90 percent of the Florida citrus market is used for juice production; whereas, California is a “fresh-oriented industry, meaning that over 90 percent of our product goes into the fresh market.”

Although California citrus looks for recommendations from Florida, “here in California, there are a lot of things that we can’t afford to do because of the [fresh] market that we’re serving,” said Houtby.”  That is what we’re fighting so hard to maintain because we cannot sustain as long as Florida has; we don’t have the luxury of sending a bad-looking piece of fruit into the marketplace like Florida can, because they just juice it. Knowing that, we’re working really hard to never get to the point that Florida has reached.”

As if the dire situation in Florida couldn’t be any worse, they battled with “another deadly bacterial-based citrus disease, citrus canker, brought in from the far reaches of the world,” Stambach said. “That’s a concern we always have with importing citrus. When we import Argentine lemons, for example, we risk our domestic plant health by exposing orchards to a lot of plant diseases they have that we don’t. We want to keep those out of our country,” noted Stambach.

Abandoned citrus trees also pose problems for the industry; they can be sanctuaries for ACP. “If those trees are dead, that’s not a problem. They may look bad, but if they are not living, that’s not a problem. It’s when those trees aren’t cared for, aren’t sprayed in a normal routine, and there is a flush of new growth, the trees provide a sanctuary for the psyllids,” he said.

“And ACP are very good at finding citrus. They’ll target the perimeters of new growth on the very first citrus they find. Boom, they’re right on it,” he noted.

“Those abandoned groves create a real problem, particularly when they’re in close proximity to other commercial acreage or even homeowners,” he said. Neglected neighborhood citrus trees can become ACP sanctuaries. “ACPs will feed on them and move on to another tree, and feed there,” Stambach explained. “All that time, if an ACP is infected with the HLB bacteria, it will spread that disease, with a latency period of 2 to 5 years.”

Stambach and his team are working on a critical program in Southern California to remove abandoned citrus trees. “Sometimes it’s just getting a hold of the landowner and making them aware of the situation,” he said. “Our county ag commissioners are really key in contacting those people. We’ve had growers go in and spray their neighbor’s orchard to help them out. There are a lot of different ways to attack that problem.”

Compared to counties in the San Joaquin Valley, Riverside and Ventura Counties typically have a big-ag urban interface, which means there is a lot of acreage intermixed with home sites—small homes with citrus trees. Stambach said, “It’s not really commercial production, but it’s a significant amount of acreage with a number of trees that don’t get treated.”

“We’ve gotten some support from some of our partners in the chemical industry. Bayer CropScience has stepped up and worked with us to put together a program. We’re really happy. We’re working hard to take [ACP and HLB] out.” Stambach said.

“Fresno has even found ACPs in residential areas,” commented Houtby on the Central Valley situation. “ACPs are endemic in Southern California, but we’re still at a point in the Central Valley at which we can control these populations and knock them down really quickly when they arrive here.”CA Citrus Mutual

Houtby points to the Central Valley’s vulnerability when citrus plant material is moved over the grapevine or from the Central Coast. “We ask that homeowners, and the citrus industry as well, not move plant material out of Southern California into the Central Valley,” she stated. “The psyllid lives on that plant material and not on the fruit. If you’re going to buy a citrus tree, buy it at a local plant nursery or a local Home Depot or Lowe’s. Don’t buy it in Southern California and drive it to the Central San Joaquin Valley,” she urged.

“Our biggest task for homeowners is that they cooperate when the California Department of Food and Agriculture knocks on the door and wants to look at their trees,” Stambach said. “That is the best way you can help us win this battle against the ACP.”

The Fight Against Food Misinformation

Kavin Senapathy: Correcting Food Misinformation and Alarmism

By Patrick Cavanaugh, Deputy Editor

Kavin Senapathy, science communicator/advocate and contributor to Forbes Magazine, among others, is tightly focused on her goal to debunk miscommunication about human health, as well as genomic, food, and genetic engineering. Senapathy stated, “There is this culture of alarmism,” about food safety and food misinformation versus the science-based reality of our food safety management. “The alarmism and fear is so amplified, people don’t realize how very safe we are right now.”

Senapathy gets her facts from the source, “I speak to as many scientists as possible, and I know how to read and dissect a scientific paper. I know there is a very important difference between cherry picking from one study to support a bias, and looking at the weight of scientific evidence,” she said.FDA, FSMA Food Safety

“I also talk to farmers and I’m learning more about the hands-on practices,” Senapathy said. “California farmers produce a wide variety of fruits and vegetables,” she said, “and we all should be eating more of them.”

“I think a lot of the fear and misinformation take away from the message of eating the right things,” continued Senapathy. “Thinking, ‘I should avoid MSG, I should avoid GMOs or xyz additive,’ really detracts from the most important message—that we should be eating less unhealthy things like sodium and saturated fat, and not too many calories,” noted Senapathy. “We should be eating lots of fruits and vegetables and whole grains.”

And though she lives in Wisconsin, Senapathy says she is amazed by how many fruits and vegetables are available, even in the wintertime. “I can go to the grocery store in February and come home with grapes, strawberries, bananas, and all kinds of fruits and vegetables,” Senapathy said. “You know, we should marvel at the bounty of this more often.”

She’s quick to thank farmers for feeding her family and those of everyone, everywhere. “We forget—with all the fear and misinformation in social media—that our food supply is more abundant and safer than it has ever been,” she noted. “We should all be appreciative and thankful for that.”

ILRP Changes Target All Calif. Farmers

Proposed Changes to Irrigated Lands Regulatory Program (ILRP) Could Impact Farmers Statewide

By Patrick Cavanaugh, Deputy Editor

 

Kings River Water Quality Coalition LogoThe recently proposed changes to the Irrigated Lands Regulatory Program (ILRP), open for public comment until Wednesday, May 18, could significantly impact farmers, according to Casey Creamer, coordinator for the Kings River Water Quality Coalition. “The proposed modifications concern the east San Joaquin Region, within Madera, Merced and Stanislaus Counties,” Creamer said. “That’s the scope of it.”

According to the State Water Resources Control Board’s (SWRCB) website, ILRP “regulates discharges from irrigated agricultural lands. This is done by issuing waste discharge requirements (WDRs) or conditional waivers of WDRs (Orders) to growers.” Discharges include irrigation runoff, flows from tile drains and storm water runoff, which can transport “pollutants including pesticides, sediment, nutrients, salts (including selenium and boron), pathogens, and heavy metals, from cultivated fields into surface waters. Orders contain conditions requiring water quality monitoring of receiving waters and corrective actions when impairments are found.”

While ILRP currently targets only the east San Joaquin region, Creamer said, “It’s a precedent-setting deal, so everything in there is going to affect not only the entire Central Valley, but the Central Coast and the Imperial Valley—that may not have near the issues or the current regulatory programs that we have here in the Central Valley. So, its very important statewide.”

Creamer emphasized, “Farmers need to know that this is not a minor issue; this is a big issue that affects their livelihoods and their ability to operate. They need to get involved. They need to communicate with their other growers, communicate with their associations, get involved and have their voices heard.”
