ACP Spread in Bakersfield Area, Ingenious Research Proceeds

Ingenious Research Effort to Fight ACP Spread with Natural Predators

Beth Grafton-Cardwell, Cooperative Extension specialist, University of California, Riverside Department of Entomology

As we have reported in-depth before on California Ag Today, the Asian Citrus Psyllid (ACP) is a tiny, mottled brown insect that poses an ever-increasing threat to the state’s robust citrus industry, as well as to residential citrus trees. The pest can spread a bacterium known as Huanglongbing (HLP) that is fatal to citrus trees. The disease has nearly shut down Florida’s citrus industry.

Beth Grafton-Cardwell, cooperative extension specialist in integrated pest management, UC Riverside Department of Entomology, explained the significance of the recent ACP spread to Bakersfield. “That is really problematic because it’s mostly in the urban areas. It’s very difficult to find, to control and to stop that spread. It’s going to move out from that region into the local citrus orchards, and so there are lots of meetings and discussions right now to mobilize growers to get treatments to help protect their citrus orchards against the psyllid.”

#CitrusMatters

To contain the ACP problem, Grafton-Cardwell stated, “There are traps everywhere, but the traps are not terribly efficient. So, we really need to carefully examine groves and flush [new leaf growth] for the nymph form,” she said.

According to Agriculture and Natural Resources, University of California’s Statewide Integrated Pest Management Program:

Adults typically live one to two months. Females lay tiny yellow-orange almond-shaped eggs in the folds of the newly developing “feather flush” leaves of citrus. Each female can lay several hundred eggs during her lifespan.

The eggs hatch into nymphs that are wingless, flattened, yellow or orange to brownish, and 1/100 to 1/14 inch long. Nymphs molt four times, increasing in size with each nymphal stage (instar), before maturing into adult psyllids. The nymphs can feed only on soft, young leaf tissue and are found on immature leaves and stems of flush growth on citrus.

The nymphs remove sap from plant tissue when they feed and excrete a large quantity of sugary liquid (honeydew). Each nymph also produces a waxy tubule from its rear end to help clear the sugary waste product away from its body. The tubule’s shape—a curly tube with a bulb at the end—is unique to the Asian citrus psyllid and can be used to identify the insect.

Grafton-Cardwell and other experts are concerned because once the ACP becomes established in urban areas, it is difficult to eradicate. “It starts spreading into the commercial citrus, and we’re off and running,” she commented.

In a ingenious effort to control the spread of the psyllid, trained teams of entomologists have imported Tamarixia radiata, a tiny wasp that naturally preys on ACP, from Pakistan to research and release in California. A cooperative effort of the University of California Riverside, Citrus Research Board, United States Department of Agriculture and California Department of Food and Agriculture, researchers are also exploring the effectiveness of another beneficial insect called Diaphorencyrtus aligarhensis to assist Tamarixia with control of the Asian citrus psyllid. To see where Tamarixia and Diaphorencyrtus have been released, visit this University of California’s website map at, “Distribution of ACP, HLB and Parasites in California,” and turn on the parasite layers.
Grafton-Cardwell said, “They’re going to inundate that area,” with natural ACP predators, “so hopefully that will push back a little bit.”

Food Tank’s Farm Tank Summit in Sacramento Reveals Knowledge Gap

Food Tank’s 1st Annual Farm Tank Summit in Sacramento Reveals Gap in Agricultural Knowledge

Good Starting Point for Constructive Conversation

By Patrick Cavanaugh, Farm News Director

Several hundred food activists attended the First Annual Farm Tank Summit in Sacramento last week, hosted by Food Tank, in partnership with the Visit Sacramento, California Farm-to-Fork Program, and University of California, Davis. Danielle Nierenberg, co-founder and president of Food Tank noted having the event in Sacramento enabled West Coast agricultural experts to contribute to the discussion.

“We were really excited to feature California agriculture, because it’s such a huge part of the American economy,” said Nierenberg. “Californians are feeding the world, and we need to really highlight what these amazing producers are doing. When the Farm to Fork program of the Visitors Bureau reached out to us, we were thrilled to partner with such an amazing group of people, as well as UC Davis folks and the Center for Land-Based Learning,” she said.

Food Tank, an abbreviation of Food Think Tank, is a 501(c)3 non profit organization focused on building a global community for safe, healthy, nourished eaters that values education, inspiration and change.

According to their website:

Food Tank is for the 7 billion people who have to eat every day. We will offer solutions and environmentally sustainable ways of alleviating hunger, obesity, and poverty by creating a network of connections and information for all of us to consume and share. Food Tank is for farmers and producers, policy makers and government leaders, researchers and scientists, academics and journalists, and the funding and donor communities to collaborate on providing sustainable solutions for our most pressing environmental and social problems.

The organization begins with the premise, “Our food system is broken. Some people don’t have enough food, while others are eating too much. There’s only one way to fix this problem—and it starts with you and me.”

With the goal of feeding the hungry world of nine billion people in a few years, “Food Tank highlights hope and success in agriculture. We feature innovative ideas that are already working on the ground, in cities, in kitchens, in fields and in laboratories. These innovations need more attention, more research, and ultimately more funding to be replicated and scaled-up. And that is where we need you. We all need to work together to find solutions that nourish ourselves and protect the planet.”

Nierenberg clarified, “I don’t necessarily think we need to scale up food production; I think we need to scale out different innovations that are working. We’re wasting about 1.3 billion tons of food annually. That’s enough to feed everyone who’s hungry today, so we don’t necessarily need to ramp up production. We need to have better distribution, and processing practices that can help get food to people who need it the most,” she said.

“We need the political will behind those things,” she continued, “to build the infrastructure necessary for farmers to have better processing facilities, to have better storage facilities, to have better roads—if we’re talking about the developing world. I don’t necessarily think that we need to invest in producing more calories; we need better calories. We need more nutrient-dense food, and we need less starchy staple crops,” she noted.

Editor’s Note: Activists overtook the stage during the event, and the conversation was notably challenging for panelists. In an effort to Cultivate Common Ground to link consumers with the farmers who grow their nutritious food—and vice versa—California Ag Today has chosen to share some interesting statements from presenters and attendees to illustrate, perhaps, where the discussion could begin:

Regarding farms and processing facilities, big is bad, and small is good.

Regarding food quality, organic produce is healthy and safe, while conventional produce is unsafe and full of pesticides.

One of many moderators from the Bay Area, Twilight Greenaway, managing editor of Civil Eats mistakenly introduced Oscar Villegas, Yolo County Supervisor, District 1, as being from Sacramento County. When Villegas corrected her, Greenaway said, “I’m showing my Central Valley and Bay Area eliteness.”

Eric Holt-Giménez, executive director of Food First, noted that farmworkers are invisible in California agriculture. “There is racism in the fields. We need more worker unions and we need farmworkers to be paid much more than they are now and the farmworkers should be getting pensions from the farmer.”

Michael Dimock, president, Roots of Change, said to the audience, “You guys are doing a great job. Keep doing it. Keep working with your NGOs. They know policy. In turn, they can work with the legislators.”

“You need to be in the capital, pursuading the legislatures to support their bills. They want to be reelected, and if they don’t do what we ask them to do, they are scared.”

“In the meantime, we have to be nice to farmers because farmers are scared. We are putting a lot of pressure on them; They are in a vice. Our movement has supported bills AB 1066 – the overtime bill, minimum wage increases, organic farming legislation, and workers’ rights.”

Kerryn Gerety, founder and CEO, Lazoka, referred to John Purcell, vegetables global R&D Lead, Hawaii business lead, vice president and distinguished fellow, Monsanto Company, and said, “There is an elephant in the room, the Monsanto rep. Monsanto has all the technology patents. We all want transparency and we need you to be more transparent.”

Continuing, “Why doesn’t Monsanto open-source some of your patents and release the intellectual property so others can take advantage of your teçhnology?”

Purcell answered, “We are an Ag company. Why would our company invest a million dollars on technology and let everyone have it? It is our investment and we need to have the opportunity for a return on that investment.

During a panel discussion of food companies including Blue Apron, Almond Board of California, and Bayer CropScience, that covered organics, Jennifer Maloney, food chain sustainability manager, Bayer CropScience, said, “We do support the organic industry, because we have biological products that work in organic as well as conventional [farming].”

Maloney also talked about agricultural Integrated Pest Management (IPM) technology such as smart sprayers that spray only targeted areas.

Matt Wadiak, founder & COO, Blue Apron, responded, “It’s not about smart sprayers; it’s about biological systems in the field and trying to lean on them instead of spraying.”

Maloney replied, “Yes, that is exactly what IPM is.”

Keith Knopf, COO, Raley’s Family of Fine Stores, commented on the organic question, “the way we see organic versus inorganic—that is not the discussion for us. What’s more important to us is, is it the candy bar or the apple?”

This two-day event featured more than 35 speakers from the food and agriculture field, interactive panels moderated by top food journalists, networking, and delicious food, followed by a day of hands-on activities and opportunities for attendees. This was the second in a series of three 2016 Summits, following the Washington, D.C. Food Tank Summit that completely sold out and drew in more than 30,100 livestream viewers. The third Summit will be held in Chicago on November 16, 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.”

“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.

USDA NRCS Works To Increase Diversity

NRCS Conducts Outreach for Diversity

By Emily McKay Johnson, Associate Editor

The United States Department of Agriculture (USDA) Natural Resources Conservation Service (NRCS) works with local growers across America to conserve the nation’s soil, water, air and other natural resources. Elisabeth “Elise” Miller, is an area engineer for the entire Southern California region. “I also serve my agency as the NRCS-California LGBT Special Emphasis Program Manager, a collateral duty that I perform on several levels to increase diversity,” said Miller.

“First, I work to educate employees within my agency, to make them better informed and more in tune to language,” Miller explained. “Then, I work to get a more diversified workforce within the USDA,” she added, to make the organization stronger and better.

“My efforts might include going to a university,” she elaborated, “trying to tie in with their resource center and encouraging more people who identify as LGBT to apply for federal jobs. Our colleges, the University of California (UC) and the California State (Cal State) University system, have a lot of really good, positive and powerful resource centers that I’m hoping will continue to help us with our outreach and pull more people in who want to work for us.”

“Certainly we do have human resources,” commented Miller. “And we do a lot of outreach. With California being so large and so diverse,” Miller said, “it is hard to reach out to everybody. We have to start with the big UC schools first. We also try to reach out to universities such as Fresno State, Cal Poly, San Luis Obispo or Pomona or UC Davis, or Humboldt State. Those would be schools that certainly we want to outreach to and try to bring more of those graduating students in under our fold.”

“My agency is a very technical agency,” said Miller. “We work on conservation-type issues—resource issues that farmers, ranchers or private landowners might deal with—requiring an agronomist, biologist or soil scientist. I often go out with a multi-disciplinary team and meet with a farmer, rancher, or just a landowner.”

“Every farmer I meet has some kind of issue,” Miller commented, “whether it’s pest management, whether it’s dealing with manure management or an erosion issue that’s going on. If they have a hillside orchard, they have to deal with that.”

“And obviously they focus a lot on drought management and water conservation,” Miller explained, “A lot of these farmers of course are forced to use groundwater, which is depleting the groundwater sources and may be causing irreparable damage.

We work cooperatively to try to help them resolve their land issues. That’s what I like about my agency—that we’re invited there. We’re not there to push a regulation. We’re there to help them to better manage. They always maintain control of their decision making. We try to give them options available and we have cost share programs to assist them, if something is identified. We work towards developing conservation plans on the property.”

The agency is also responsible for the soil survey work. “We map the soils five feet deep,” said Miller, “to gather information, resource information, which has worked fantastically well for a farmer to know what kind of soil he’s dealing with. It may make a difference on how a farmer irrigates. It may be why he’s having a problem with a crop or many other areas that could be helpful to them.”

“We are in the community. We’re very much aware; we know who the farmers are, we know what the issues are and we work with farmers to try to address their land problems. We don’t just pop in and then pop out,” Miller said.

The United States Department of Agriculture (USDA) Natural Resources Conservation Service (NRSC) works with local growers across America to conserve the nation’s soil, water, air and other natural resources with voluntary programs and science-based solutions that benefit both the landowner and the environment.

Weedy Rice Challenges Some Rice Growers

Weedy Rice Crops Ups Again in Northern Calif. Rice Fields

By Patrick Cavanaugh, Farm News Director

In Northern California, rice growers typically prepare to start harvesting in mid-September, but some growers have endured a lot of weed pressure from weedy rice (Oryza), also known as red rice, according to Whitney Brim-DeForest, a UC Cooperative Extension Rice Farm Advisor in Sutter, Yuba, Placer, and Sacramento Counties who focuses particularly on weeds. Red rice is actually the same species as cultivated rice, but it produces far fewer grains per plant and is therefore considered a pest.

Brim-DeForest said weedy rice is common in the Southeast, but not in California. “We’ve been pretty lucky in California in that we actually don’t have a big problem with it,” she said. “It’s a big problem down in the southern U.S. and they have been dealing with it in for a long time; but we have had it crop up. I think the last time was in 2006, and we managed to deal with it. It somehow popped up again in the last couple of years, so we’re dealing with it again.”

How weedy rice reached California is apparently a mystery. “We don’t really know the source of it, to be honest,” said Brim-DeForest. “We’re investigating that through research, hopefully starting this fall,” she said.

Brim-DeForest said growers have few choices to control weedy rice. “Growers that have it will either have to rogue¹ it out, pull it out by hand or sacrifice that field and spray it with Roundup,” she said, “which would kill the rice as well. And, if the rice grower doesn’t know he has weedy rice in the field, it could hurt him later at the rice mill,” explained Brim-DeForest.

“Once harvested, the rice goes to the mill. If a certain amount of red rice bran (the outer layer surrounding the rice grain) is discovered, the mill will not accept it and could reject the entire load,” she said.

Brexit Hurts Wine Exports To U.S.

Brexit-Devalued Pound Hurts Wine Exports To U.S.

Jon Moramarco, managing partner of Bonded Winery 166 (BW 166 LLC), is a third-generation wine professional at the company that his grandfather, Giuseppe Moramarco, a tenth-generation wine professional émigré from Italy, acquired BW 166 LLC in Los Angeles from the Jesuits during Prohibition.

Moramarco explained the effects of Brexit on wine imports to the U.S. “The UK pound has dropped in value versus almost every currency,” he began. “The UK will not want to raise their price in British pounds, so it will probably drive them to become interested in any exports to the UK from the U.S. They will want to have a lower price in U.S. dollars, which will be tough for producers to do in the U.S.”

Continuing, “Now those [EU] European wine exporters are going to say, ‘Well, I don’t want to sell at that price to the UK. I’m gonna go try and sell more in the U.S.'” noted Moramarco. “So we will see more imports coming into the U.S. from Europe.”

“So you kind of have a double whammy for wine,” Moramarco concluded, “because they’ve kind of lost the margin in one of their key markets.” He anticipated “difficulty in exports with people wanting to drop price,” as well as a greater “increase in people wanting to import into the U.S.”

CULTIVATING COMMON GROUND: Economic Analysis of Drought on California Agriculture

Editor’s note: We thank Aubrey Bettencourt for her contribution to California Ag Today’s CULTIVATING COMMON GROUND commenting on the report, “Economic Analysis of the 2016 Drought for California Agriculture,” released this week. Lead UC Davis author Josué Medellín-Azuara’s response can be read below.

By Aubrey Bettencourt, executive director, California Water Alliance (CalWA)

Josué Medellín-Azuara, Duncan MacEwan, Richard E. Howitt, Daniel A. Sumner and Jay R. Lund of the UC Davis Center for Watershed Sciences, ERA Economics and the UC Agricultural Issues Center reported their views on the economic impact of California’s continuing drought on agriculture this week. The study, “Economic Analysis of the 2016 Drought For California Agriculture,” proved to be uncommonly riddled with errors, questionable metrics and inaccuracies; it’s a continuation of a disturbing recent trend.

The authors claim that about 78,800 acres of land might be idled due to the drought, but a quick Google search shows a single water district that had more than 200,000 acres of fallowed land in 2016. There are more than a hundred other water districts throughout the state, and most are reporting idled acreage.

In another irrigation district in Yuba County, more than 100 agricultural users have been cut off entirely, leaving their nearly-mature crops and fruit and nut trees without water. [North Yuba Water District (NYWD)]

This year the federal and state water projects announced they would provide agriculture with 55% of their water. Two months ago, they reduced the estimate to 5% south of the Delta, and they are struggling to even deliver that amount.

Across the state, water prices have increased dramatically, whether pumped from the ground or bought on the faltering water-exchange market. Water that costs less than $250 per acre foot in 2012 now costs up to $750 or more.

It doesn’t take a doctoral or economic degree to understand that when the price of water goes up, the cost to produce food also goes up. Farmers may be getting more money for the produce they grow, but they are watching their bottom line shrink because it costs more to grow it. Even water from their wells isn’t free; pumping takes energy, and energy costs money too.

Adding to rapidly increasing costs are the new minimum wage, capped work hours, and hundreds of regulatory mandates from the 80+ local, state, and federal agencies that oversee every aspect of California farming and bury farmers in paperwork and red tape. Compliance takes time away from growing food, and it costs money.

Take a look at rice farmers. Growing rice today is a losing proposition. After the labor, cost of rice plants, fuel, fertilizing, care, harvesting, drying and milling, growers pay substantially more to grow rice than they can charge for their crop. Many have converted rice paddies to other uses, and some sell their water or take money from federal agencies and conservation groups to create wildlife habitat in order to simply stay afloat. Some are selling off their land to developers, a lose-lose decision affecting everyone.

On main street, consumers are another group taking a second, alarmed look at their grocery, water and sewage bills. All are rising far faster than inflation. Whether you are talking about the price of fruit, bread and eggs or the cost of taking a shower, all have been increasing over the past five years because of the drought.

To really understand what’s happening, take a drive out of the city and into the countryside where your food is grown. Stop at a roadside produce stand or park your car and strike up a conversation with some ranchers and farmers in a small town cafe.

After you hear their stories, you may realize that almonds and pistachios are not as labor intensive as strawberries, tomatoes, cucumbers, grapes, beef, lamb or many others out of the nearly 450 crops grown in California. Some crops are thirstier than others, too. This doesn’t diminish the value of these fruits, nuts, vegetables, and proteins. The value of water is what it provides us: in this case, safe, local, and hopefully affordable food.

But commonsense interviews and case studies of actual operations — once the heart of any competent agricultural economic study — are virtually missing from the report’s statistical models built on university computers, research hypotheses and tables of statistics.

The drought has hurt California farmers, and it is hurting Californians wherever they live. Gross income may be up, but net profits are down, and the rate of decline hasn’t hit bottom yet.

Aubrey Bettencourt is the executive director of the California Water Alliance (CalWA), a leading educational voice and authority on California water. CalWA advocates for the water needs of California families, cities, businesses, farmers and the environment.

Editor’s note: California Ag today thanks Josué Medellín-Azuara, senior researcher, UC Davis Center for Watershed Sciences, and lead author of “Economic Analysis of the 2016 Drought For California Agriculture,” published this week, for his response to several claims made by Aubrey Bettencourt (above).

Josué Medellín-Azuara told California Ag Today, “I will not go over debating the comments which I very much welcome and respect, but I would like to provide some thoughts instead.”

1) “Through remote sensing,” Medellín-Azuara said, “we estimated summer idle land in Westlands by the end of the irrigation season to have been 170K acres in 2011 and just above 270K acres in 2014,” based on NASA data. The difference can be explained by some drought effects and other conditions, according to Medellín-Azuara, “so idled land differences should be taken with a grain of salt. As a point of interest, most of the fallow land we estimated was on the Westside of the south San Joaquin Valley.”

2) In addition, Medellín-Azuara clarified, “My understanding is that there is a cost issue and a cutoff issue. We estimated about 150 TAF (Thousand Acre-Feet) of [water] shortage in the Sacramento Valley in our study. At current conditions for North Yuba Water District (NYWD) agriculture is no more than 3 TAF from my reading of the attached document. I am not saying the cutoffs are not hard for the more than a hundred users, but [I] also want to put numbers into perspective.”

3) “From what I’ve heard and read,” Medellín-Azuara stated, “the timing [of] more than quantity of the projected releases is unfortunate. One of the things we highly encourage in this and past reports is easing of low environmental impact water transfers among users.”

UC Davis Researchers Point to Government as Culprit for Fallow Land

Government Policies—not Drought—Blamed for Fallow Land

By Patrick Cavanaugh

“Neither snow nor rain nor heat nor gloom of night stays these couriers from the swift completion of their appointed”¹ water deliveries.

Not even drought can be blamed for land fallowing due to lack of water deliveries to Central Valley federal water users.

Jason Peltier, manager of the Federal water district, San Luis and Delta-Mendota Water Authority, said, a UC Davis study released this week, “Economic Analysis of the 2016 Drought For California Agriculture,” has confirmed that failed government water policies—not a lack of rainfall and snow pack—are responsible for the widespread water shortages and the fallowing of more than 300,000 acres of land in the federal water districts on the Westside of Fresno and Kings Counties.

“It raises this question,” Peltier asked, “When do we get honest and start talking about the regulatory drought—the man-made drought, the policy-induced drought, the policy-directed drought? We can’t even have an honest conversation about that.”

“That our opponents want to deflect and obscure that whole conversation is telling,” he continued, “because we have a tremendous story of adverse economic impact as a result of failed policies. When they tried to protect the fish, they took our water away and they made the supply unreliable. ‘Just a huge failure and they don’t want to address it; they don’t want to deal with it. The same agencies are fixated with their false confidence or their false certainty, their false precision, in terms of how to help the fish.”

Peltier explained the regulators failed to deliver all of the 5% allocation [née water delivery reduced by 95%] to growers in the federal water districts south of the Delta. “It’s nonsense,” he reiterated, that part of the insufficient 5% was never delivered this season. “It’s avoidance of the reality that the regulators have constricted the heck out of the water projects and made it so—even in wet years, and like this year, a normal to wet year—we’ve got huge amounts of land out of production,” Peltier said, adding that almond growers in the federal water districts are not getting a late, post-harvest irrigation, which can hurt next year’s production.

UC Davis Foundation Plant Services Serves the Ag Industry

UC Davis Foundation Plant Services, Critical Service to the Ag Industry

By Brian German, Associate Editor

UC Davis is home to Foundation Plant Services (FPS), a plant repository the world relies on for plant importation and quarantine, disease testing, virus elimination, and DNA identification services for a variety of plants and rootstocks. FPS also coordinates the release of UC-patented horticultural varieties and provides an essential link between researchers, nurseries and producers.

“Established at UC Davis in 1958, FPS has grown from a small kind-of-mom-and-pop scientific effort sourcing out cherry and grapevine cuttings that have been screened for virus to nurseries so that they could make better plants for growers,” said Deborah Golino, director of FPS since 1994. “FPS has grown to the point where it is a self-supporting center. We owe a lot to the growers and nursery industry that have supported us over these years,” she said.

Today FPS employs about 35 people on “soft money,” including scientists in the lab and people in the green houses, as well as propagators, and field workers. About 250 acres of various plantings—largely grapes of course—plus programs with strawberries and sweet potatoes that are mostly run in green houses,” noted Golino.

“All other programs circle around getting correctly identified, valuable commercial plant materials (cultivars). Many times, great people save varieties, and screening them for virus and making sure that commercial nurseries have that virus screened materials, so they can make plants for farmers that have the added productivity and sustainability that comes with clean material,” explained Golino.

FPS advances clean material in the lab by cutting out a meristem shoot tip and grow a plant from that. “Let’s say we have a valuable Chardonnay that came in from France. It’s a new clone and it has a couple of viruses in it. In a process that takes about a year, we take a micro-shoot tip culture and regenerate a plant,” Golino said. “For reasons that aren’t really fully understood, regenerating that plant from the tiny .5 millimeter piece gets rid of viruses. That’s our therapy, but what we give to most nurseries and growers who buy material from us is that little plant grown up in the field, and we might have hundreds or even thousand of cuttings of some root stocks.”

“The most common route for advancing a clean plant cultivar is by nurseries coming in to buy several hundred cuttings,” Golino explained, “and plant them in a field. Those plantings grow big mother plants from which they harvest more cuttings to be grown and eventually sold to growers. It’s a multi-year generational process.”

“We have over 900 cultivars of grapes and over 5,000 accessions because we have multiple clones of Chardonnay and Pinot Noir,” Golino said. “All of that material is improved by the technology we have used, technology that has been developed by other UC researchers to conduct DNA identification to ensure accuracy, which is part of the FPS mission.”

“That material is held as a trust to improve our agricultural offerings to growers of fruit trees and other crops,” Golino said. “Even though much of the material is not produced by UC growers and might even be produced by a Cornell or a Michigan breeder, it is still important to our agriculture here in California and across the country since the 2008 Farm Bill was passed. I think we owe Congressman Sam Farr (CA -20) a tribute for that. Since then, there has been money for the National Clean Plant Network with USDA’s Animal and Plant Inspection Service (APHIS) and they have funded about 20 clean plant centers around the country.”

“FPS certainly provides the highest level of screening in the world,” Golino stated, “and I think we might be the biggest too. In this modern world where margins are so thin, the universities are so tight for money for research and especially for teaching, and they have so many challenges taking care of those things, the experiment station does not have much money for service work, like the work that is done at FPS.”

“FPS conducts its work for industry, and that isn’t really directly relative to the university’s mission which has to be strictly accommodated. That is why California grape and fruit tree nurseries have assessed themselves to fund our programs since the mid 1980s,” said Golino. “And then we have the clean plant money on top of that, and our grape nurseries actually pay user fees on the plant material they make from our material. That keeps the doors open and keeps us doing world class work,” Golino said.

Vigilant Seed Bank Reduction for Weed Control

Vigilant Seed Bank Reduction: Whatever it takes, don’t let weeds set seed.

By Patrick Cavanaugh, Farm News Director

For the past 15 years, Robert Norris, professor emeritus and vegetable crops weed specialist, UC Davis Department of Plant Sciences, has continued to attend Weed Day each year at UC Davis and to contribute weed photography for CalPhotos, a UC Berkeley Digital Library Project photo database of world-wide plants, animals, landscapes, and other natural history subjects developed to provide a testbed of digital images for computer science researchers to study digital image retrieval techniques. Norris was involved with initiating the Plant Protection and Pest Management Graduate Program at UC Davis.

“I’ve been a botanist since I was 14 years old,” Norris said, “and I still have a lot of passion regarding weed control.” Norris has a strong and steady philosophy on weed control and it all comes down to seeds. “The last 25 years of my work, I looked at population dynamics of weeds, like seed longevity in the soil and what we call the size of the seed bank also known as the seed production by weeds. That’s really where I spent most of my time.

“I found that most people have a very poor idea of how many seeds are produced by a weed. This led me to question some of our current management philosophies; namely, the one that comes out of entomology—the use of thresholds (or how many weeds need to be present before treating them),” noted Norris. “I felt that for weed science, thresholds were not the way to go, and my position has been vindicated by the problems we’ve run into using thresholds.”

Norris offered the example, “Barnyard grasses are probably one of our most serious summer grass weeds. A small plant can produce 100,000 seeds; while a big plant, well over a million. I can remember going put in a tomato field years ago and looking at one barnyard grass plant. Because I had been working with it, I can say that plant probably put out 50,000 seeds. If you spread those seeds around an acre, that’s enough to give you serious yield loss the next year,” Norris explained. “Again, that’s one plant, spread out over an acre. Obviously its seeds wouldn’t spread over an acre [on their own], but with our tillage equipment we would move it around quite a bit.”

“My bottom line for about 30 years now is: Don’t let the weeds set seed. Whatever it takes, don’t let them set seed,” Norris said. If you follow that philosophy, Norris said after a while you drive the seed bank down.

“Many people don’t realize this, but some of our really big growers got on to it a long time ago. One farming operation I worked with for years, J. G. Boswell Co., with most of its land in Kings County. “I knew the manager in the late ’50s, into the ’70s. He now is retired now, but he came to this conclusion himself back in the late ’50s,” Norris said. “I haven’t been on Boswell’s property now for 20 years, because I retired. However, if you go down there, you will not see a weed problem, at least not like most growers.”

“The difficulty really is, in order to carry out this philosophy, you need to use hand labor for weed management and it is becoming less and less easy to find,” explained Norris. “Most weed management is done on a one-year one-crop basis; whereas, the type of management we’re talking about where we’re really thinking seed bank dynamics, has to be done over multiple years. Another big problem that I still see is if you miss one year, you can undo 5 to 10 years of what you’ve just been doing, because of this high seed output,” he said.
