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.”

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.

Duarte Nursery Loses Battle Against Army Corps Of Engineers

Ruling in Favor of Army Corps is Game Changer for Agriculture

By Patrick Cavanaugh, Farm News Director and Laurie Greene, Editor

 

Startling California family farmer, John Duarte, president of Duarte Nursery, Inc., his attorneys, and others who have also kept a close watch on the case, Duarte was dealt a serious blow recently in the biggest fight of his life—the right to farm his own property. This legal outcome may portend a game changer for American agriculture as a whole.

 

Background

Duarte Nursery and the U.S. Army Corps of Engineers (Army Corps) have been engaged in a long legal dispute over private property rights since the family purchased a 450-acre agricultural property in Tehama County in 2012 and planted wheat that fall.

As reported in, “Duarte Farmland Under Siege,” (California Ag Today, March 11, 2016), John Duarte recalled, “The property is in some slightly rolling grasslands, and has some minor wetlands on it, vernal pools, vernal swales. Like most grasslands, wheat areas and wheat plantings, we had a local contractor go out and plow the field for us, 4-7 inches deep, and we flew on some wheat seed for a winter wheat crop in 2012.”

The U.S. Army Corp of Engineers accused the farm of “deep ripping” the property (three feet deep), “which we were not,” Duarte said. Legal action ensued with the Army Corps issuing a cease and desist notice in early 2013, according to Duarte, without evidence or basis for their accusation. Duarte Nursery attorneys, under the Freedom of Information Act, requested evidence of deep ripping, the assumption that apparently warranted a cease and desist notice.

Without responding, according to Duarte, the Army Corps sustained the cease-and-desist notice without a hearing and without evidence. “They obstructed our farming operations indefinitely,” Duarte said in March 2016.

 

Current Scenario

Duarte’s attorneys are now scrambling to prepare and file appeals to Eastern District Federal Court Judge Kimberly Muller’s June 10 ruling that by plowing his land to grow wheat, Duarte could pollute vernal pools on his land, violating the Clean Water Act.

Pacific Legal FoundationOn behalf of Duarte Nursery, Pacific Legal Foundation attorneys have moved for reconsideration or certification for immediate appeal on several Clean Water Act issues. “We expect a decision from the court any day on this motion, which will determine whether Duarte Nursery can immediately address the trial court’s legal errors in the appellate court, or will have to go through a trial first on whether the government is entitled to a penalty.” (Source: “Duarte Nursery seeks immediate appeals in Clean Water Act case,” Tony Francois, Pacific Legal Foundation, June 30, 2016)

 

Reaction to the Ruling

California Farm Bureau Federation and Pacific Legal Foundation attorneys had great confidence that Duarte would be vindicated in the action brought by the Army Corps several years ago. “They are just astounded,” Duarte said. “I thought we might have to go to trial on some of our issues, but I did not think we would lose our issues and have the judge rule against us on the other side,” he said.

Duarte clarified, “We are talking about farming activity that only occurred on rolling land—land with dismal vernal pools and flails.” Duarte noted there is no controversy as to whether this tillage was four to six inches deep. “Both sides agreed this is four to six inch deep tillage. Both sides agree that this property had farmed wheat before,” he said.

 

Legal Implications

“The Army Corps’ position is they don’t know how long is too long, but at some point if you haven’t farmed wheat, you lose your ability to continue farming wheat,” Duarte continued. “As it is a rangeland, you cannot plow your ground without a permit from the Army Corps, which they’re not going to grant because there are wetlands,” he said.

“All of the Food Security Act protections for farming—our ability to idle ground and then bring it back into production—to ensure available food production resources—are gone,” Duarte said. “This is a very extreme ruling. It’s extreme of the law in a lot of different ways. It’s a game changer for agriculture. We’re meeting with Paul Wenger, the president of the California Farm Bureau and seeing what they want to do. I think it’s on a lot of folks’ radar,” said Duarte.

“According to the Clean Water Rule definition of “Waters of the United States” (WOTUS), everything is a wetland and farmers are not exempt,” Duarte stated. “Any tillage that the Army Corps, by their own standards, does not deem to be an ongoing agricultural operation, farmers have liability. Their settlement discussions were in the $5 million to $6 million range, and we’re talking about shallow tillage through vernal pools that covered maybe fourteen or sixteen acres over this property. We can show that those vernal pools are completely intact,” noted Duarte.

Duarte noted that consultants have been at the land to inspect the vernal pool wetlands that concern the Army Corps of Engineers, and have confirmed that all the biology has been restored. “It’s all wetland plants across the vernal pools. They’re not topographically damaged,” said Duarte. “We didn’t re-contour them, we didn’t till them, we didn’t grade them, we didn’t deep rip them such that the restrictive layers of soil no longer perched water—none of that,” he emphasized.

 

A Game Changer for Ag

“Every property owner should be concerned,” Duarte warned. “Basically, what they’re saying is if wheat is profitable for a window of time because of whatever market or geopolitical reasons, you can farm wheat. If you stop farming wheat for a decade because it’s not profitable, or because you have a lease with a cattleman who’s paying you decent money, or you just don’t have the capital to plant wheat, or you just don’t want to plant wheat, then you will lose the right to farm it in the future. You cannot adjust your farming enterprises to the markets or to your business plans or you will lose your right to farm.”

Duarte believes that the ultimate goal of the Army Corps of Engineers is to be able to tell you what you can and can’t do with your land on any given day. “They want simple control over how you use your property and discretion over what property is put into permanent habitat and what property remains rangeland. They do not believe that private landowners have any inherent right to farm their property to meet market demands.”

As for the ruling, Duarte said he plans to appeal it. “This ruling is in many ways right in the face of several completions that have come down in court last week,” he said. “A lot of this ruling hinges on the opinion in Rapanos v. United States, where senior Associate Justice of the Supreme Court of the United States Anthony Kennedy said wetlands either have to be navigable waters of the United States or tributaries or related.

As summarized in, “The Practical Application of the Significant Nexus Test: The Final Waters of the US Rule,” (by Lowell M. Rothschild, National Law Review, June 8, 2015):

The significant nexus test requires a determination of whether the water in question – alone or in aggregation with other similarly situated waters in the region – significantly affects the chemical, physical or biological integrity of a traditionally navigable or interstate water or the territorial sea (with “significant” meaning “more than speculative or insubstantial.”). The “region” is the watershed that drains to the nearest traditionally navigable or interstate water or the territorial sea, and waters are “similarly situated” when they function alike and are sufficiently close to function together in affecting downstream waters.
supreme court building

“That was one judge, who had none of the other eight judges agreeing with him,” said Duarte. Nevertheless, Duarte said Justice Kennedy was not correct. “We had four judges that said navigable is navigable. If the Clean Water Act says it exempts, it defines what jurisdictional waters are navigable waters in the United States, and then it defines what jurisdictional waters are. If you look in the Clean Water Act, it says that plowing shall never result in a discharge into waters of the United States,”  said Duarte.

“The language in the exclusion of the Clean Water Act is very clear. What this case tells us is that no regulatory legislation can be created with language that is durable to give private parties any protection with the government,” Duarte explained. “There’s no language clear enough that over time will be undermined by agency rule making and judges that give American public any protection against the government.”

“I don’t know how we will solve problems legislatively in the future,” he remarked. “I don’t know that any responsible Congress can pass a law that restricts activity, no matter what the protections,” Duarte said, clearly frustrated. “The Clean Water Act’s protections are incredibly clear. It is not badly worded. The protections are in there. The protections are careful; they’re clearly articulated; they’re very strong, and they’re completely obliterated,” he said.

Duarte is disappointed and has a long way to go in the appeals process. “All I can say is: Warning to all farmers across the land—this is what can happen. We’re just not strong enough, nor is it right for us to carry this entire thing; my family has already spent $1.5 million defending this case, and it’s likely to go to $2 million. We are going to be looking for help.”

Sparked Cultural Interest in Gardening and Locally Grown Produce

Locally Grown Food Inspires Consumers to Learn More, Garden at Home 

By Laurie Greene, Editor

Cultural changes in eating habits are sparking an added interest in locally grown produce. Scott Steinmaus, professor in the Biological Sciences Department at California Polytechnic State University, San Luis Obispo (Cal Poly SLO), outlined the surge in local produce purchasing and how it is igniting consumer interest in growing their own gardens.

“The food craze is a real big movement right now,” Steinmaus stated, “especially with urban folks. Some of the biggest scenes are the foodie craze—that farm-to-table idea of buying locally, organically-produced food.”

Scott Steinmaus, professor of Biological Sciences Department at Cal Poly San Luis Obispo.

Continuing, “And the cooking shows are out of control-popular, right? Where does the food come from? It comes from here; this is what it’s all about,” he said, with pride.

The growing trends are also reinvigorating students to become more involved, according to Steinmaus. “Students are asking where their food comes from,” he commented, “and who the farmers are that produce such healthy fruits and vegetables. That is an exciting part of our discipline as well—this foodie craze, and I think our students want to become a part of that,” he reflected.

The push for local produce is also inspring more people to grow their own home gardens. “When they garden, they get it,” Steinmaus explained. “And as soon as people get their hands dirty and as soon as they produce their first tomato; there’s nothing more empowering than producing your own food,” he said, “even if it’s a little bit.”

With this renewed interest in home gardening, Steinmaus observed, many are discovering their preconceived notions of farming were not quite accurate. “We’re working with the American Horticultural Society, putting together the videos that show people farming isn’t what you might think it is; it is actually completely different.” Steinmaus said.

“Farming involves a lot more than a green thumb,” he elaborated. “It requires the understanding of growing cycles and identifying various deficiencies. It utilizes very high technology. It is producing food; there is nothing more empowering than putting food on your kitchen table that you grew in your garden, or was grown by a farmer you know just down the street, and you know his [or her] name,” said Steinmaus.

Red, White and California Blueberries

Celebrate Independence Day with Native Blueberries

By Emily McKay Johnson, Associate Editor

As we celebrate 240 years of America’s independence, we look forward to indulging in festive red, white and blue foods. One of the best ways to incorporate blue in our holiday spread is to serve plenty of California blueberries.

Mark Villata, executive director, U.S. Highbush Blueberry Council.

Mark Villata, executive director, U.S. Highbush Blueberry Council.

Mark Villata, executive director of Folsom, California-based U.S. Highbush Blueberry Council, explained California is an important blueberry production state as, “It is among the top five producers, nationally. We produce [blueberries] in about 38 states nationally, but nine states account for about 98 percent of our total production, and California is in that top five,” he said.

“Last year, California produced about 62 million pounds of blueberries,” Villata said; “this year’s crop looks like it could be close to 70 million pounds. Total yield has been increasing each year as new plantings come into maturity and start to produce blueberries.”

California is an important player in the berry market, and blueberries are one of the healthiest fruits consumers can eat. “Of course we’re lucky here in California to have a crop that is so readily available that is also incredibly healthy for us all,” Villata noted.

And blueberries are almost the perfect crop for celebrating the Fourth of July because they are native to the region. “Blueberries play well into any Fourth of July barbecue,” said Villata. “Blueberries are so diverse, they can be incorporated in salads, smoothies, breakfasts, desserts, and more. “We bring blue to the red, white and blue festivities,” he declared.

JUST RELEASED: Monterey County Ag Value Up Nearly Eight Percent

Monterey County 2015 Crop Report Shows Ag Value Up 7.75 Percent

By Patrick Cavanaugh, Farm News Director

Monterey County Ag Commissioner Eric Lauritzen announced TODAY the production value by farmers in Monterey County for 2015 is $4.84 billion, an increase of 7.75% or $348 million over the previous year. According to the the 2015 Monterey County Crop Report released TODAY, the Monterey is again the fourth highest Ag producing county in California, following Tulare, Kern, and Fresno Counties.Lettuce fields

“Crop values vary from year to year based on production, market and weather conditions,” said Lauritzen. “As often the case, there was much fluctuation in the 2015 values, with 22 commodities down and 29 commodities increasing in value.

Notable results include:

  • head values increased 12% on better pricing.
  • Head lettuce showed a decline of 2% with fewer acres planted but higher prices.
  • Spring mix and salad products also declined in overall value.
  • Strawberry values increased by 21% on increased acreage and higher production.
  • Cauliflower and celery each saw values increase by approximately 25%. Celery showed a decrease in production with stronger pricing and cauliflower posted increases in both production and pricing.
  • Winegrapes declined 25% in 2015, after above-average production in previous years. This followed the statewide trend, with lower production and slightly higher prices.
  • Despite reduced acreage related to the drought, the value of nursery products increased by 11% on stronger pricing for many products.

“It is always important to note that the figures provided here are gross values and do not represent or reflect net profit or loss experienced by individual growers or by the industry as a whole,” Lauritzen clarified. “The numbers are big and only tell part of the story. It’s really about diversity and the ability to withstand changes, whether it is commodity change or Mother Nature,” said Lauritzen. 

“Growers do not have control over increased input costs such as fuel, fertilizers and packaging, or drought and labor shortage conditions,” Lauritzen explained, “nor can they significantly affect market prices. The fact that the gross value of agriculture increased reflects positively on the diversity and strength of our agriculture industry and its ability to respond to the many challenges,” he noted.

“The mainstays in Monterey County are the cool season vegetables,” said Lauritzen. “County growers are able modify planting programs even within the same year depending on market strengths or changes in consumer needs. When the cable food shows or restaurants decide to feature certain vegetable there is suddenly increase demand so Monterey County growers are often flexible in their planting schedules to meet demand.

“The Salinas Valley floor is very tight on acreage and available land planted out on the bench lands,” he said. “And growers are being asked to produce more with the same amount or even less ground and we are seeing that it increases prices,” he noted.winegrapes

“Each year we like to highlight a component of the industry in our report,” Lauritzen elaborated, “and this year we chose Certified Farmers Markets. We include a short piece on some of the people who produce and sell their own products directly to consumers at the 14 markets in Monterey County and elsewhere,” he said. “This important segment of our industry lets consumers meet farmers face-to-face and to become more directly connected with the food they eat.”

“Monterey County is proud to produce the crops that are healthy for the nation,” Lauritzen said, “and if consumer demand really matched what we need for a healthy diet, there would not be enough vegetables produced. We produce the food that consumers need to eat and it’s not just an economic driver for our region, but for the health of our nation,” he added.

“This 2015 Crop Report is our yearly opportunity to recognize the growers, shippers, ranchers, and other businesses ancillary to and supportive of agriculture, which is the largest driver of Monterey County’s economy,” Lauritzen summarized. “Special recognition for the production of the report goes to Christina McGinnis, Graham Hunting, Shayla Neufeld, and all of the staff who assisted in compiling this information and improving the quality of the report.”

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.”

Steve Koike on Resistant Cultivars

The Search for Resistant Cultivars

By Emily McKay Johnson, Associate Editor

In the second part of our series with Steve Koike, plant pathology farm advisor for UC Division of Agriculture and Natural Resources, Cooperative Extension in Monterey County, the focus is on the critically needed research on resistant cultivars. Koike, who has focused his research since 1989 primarily on the understanding of disease systems and the investigation of new methods of disease control, said, “The role or the need for resistant cultivars is tremendous.”

“Some good case studies of resistant cultivar research address soil-born problems on lettuce,” Koike explained. “For example, Fusarium wilt and Verticillium wilt on lettuce could be managed lightly; but in order to overcome those diseases, resistant lettuce varieties need to be in place.”

Steve Koike, UC Cooperative Extension, Monterey County.

Steve Koike, UC Cooperative Extension, Monterey County.

“First discovered in 1995 on the Central Coast,” said Koike, “Verticillium wilt has the potential to infect and damage numerous different crops. And although Fusarium wilt was typically unseen in the San Joaquin Valley, it has recently begun to appear on the Central Coast.”

Continued improvement of management techniques upon discovering initial disease symptoms is necessary, according to Koike. “Symptoms of the disease usually appear on the lower leaves of plants, around the edges, and the areas between the veins can turn a yellowish-brown.”

“Strawberries currently have three really important disease pressures state-wide: Verticillium wilt, Macrophomina (charcoal rot) and Fusarium wilt,” Koike commented. “Even the fumigation tools we have are not cleaning them up 100 percent, so we have problems.”

“We will continue to have problems,” Koike elaborated, “until there are truly resistant strawberry varieties to those pathogens. Plant breeders understand that IPM management of these diseases is so dependent on developing resistant varieties,” he said, “but we’re not there yet. We do not yet have truly resistant lettuce or strawberry varieties out in the field,” Koike said.

_______________________________

Koike and his fellow researchers discovered a new race of the downey mildew pathogen in spinach that has been designated race 16. While there are some varieties that are supposedly resistant to race 16, Koike noted that there is still more research to be done.

Downey Mildew Continues to Challenge Leafy Greens

Downey Mildew Continues to Threaten Lettuce and Spinach

By Patrick Cavanaugh, Farm Director

One of the many facets that makes California Agriculture so successful is the hard-working group of farm advisors who assist growers with a multitude of plant and pest issues. Steve Koike, plant pathology farm advisor for UC Division of Agriculture and Natural Resources, Cooperative Extension in Monterey County, noted, “It has been a fairly typical year, and I wouldn’t say any particular new disease has been noteworthy, which is good for the growers.”

Steve Koike, farm advisor of UC ANR Cooperative Extension, Monterey County.

Koike, whose research focuses primarily on understanding disease systems, identifying new diseases and examining new methods of disease control, said growers “don’t like to see new diseases come out of our work. The main concern, downey mildew, continues to be challenging for both lettuce and spinach growers.”

“We started in the early spring with heavy mildew on both lettuce and spinach crops,” explained Koike, “and it’s remained pretty heavy on lettuce throughout the spring and early summer here. Spinach downey mildew goes up and down, which is not unusual.” he said. “We had some heavy mildew weeks for spinach growers, then we didn’t hear anything, then we heard that it had died down, and then ten days ago there was another surge. It’s one of those things that is hard to predict because it is variable.”

Since starting his farm advising position in 1989, Koike has been involved in educational programs and applied research in vegetable, fruit and ornamental crop diseases. Because downey mildew can overwinter in perennial crops, its continued occurrence is not too surprising.

“Earlier this year, Jim Correll, my cooperator at University of Arkansas, other leaders in the industry and I finally did confirm race 16, a new biotype of downey mildew. A few years ago, it was only race 12; it is moving target,” he noted.

“Although we have confirmed Race 16 on spinach, we are a little concerned because there are reports of disease on some race 16-resistant varieties.” Koike said.

Tomato Distributor Works With Large, Small Scale CA Farms

Morning Star Company Supplies Tomatoes to Large Distributors 

By Emily McKay Johnson, Associate Editor

Renee_Rianda

Renee Rianda with Morning Star Packing discussing the California tomato processing company

The state of California has an ample supply of tomato processors and growers. Renee Rianda, a representative with Morning Star Company, talked about the Woodland, Calif. packing industry that mainly supplies to large distributors. “Morning Star company is the overall umbrella. Morning Star is a big player.” she said, “We are unique in the fact that we are owned by one person.”

The majority of California tomatoes are used as an ingredient in other brands. Morning Star is a name that is familiar with companies such as Domino’s Pizza and Heinz Ketchup. They are not branded like companies such as Del Monte or Campbell’s, but they are used in prepared foods for grocery stores.

“Where I fit into this whole massive situation is I deal with the growers.” she said about her role with the company, “I use roughly a couple hundred growers which is not quite everybody in the state but most of them.”

The fluctuation in supply and demand for tomatoes can vary from year to year. Rianda said that is why they work with a variety of farms in California, “We have everybody from a small individual grower of everything to larger family farms that do a variety of commodities.”

Though there is not a panel or board of directors, the Morning Star Company base is efficient. “We’re very flat as far as an organization goes.” Rianda said, “Everybody has their expertise in the areas that they are best versed in.”

Rianda likes to keep herself updated at conferences around the state. In turn, she can help growers have a commodity to sell. Using the right products is key to Rianda, “That way everybody can still have ample tomatoes to eat.”

RAIN Damages Alfalfa; Benefits Wheat

Above-Average California Rain Affects Larry Hunn’s Crops

by Emily McKay Johnson, Associate Editor

For fourth-generation farmer Larry Hunn of Hunn & Merwin & Merwin, Inc., based out of Clarksburg, Calif., the price of alfalfa is low this year due to water damage from late rains. Nevertheless, cannery tomatoes, cucumbers, safflower and wheat are looking pretty hopeful.

Larry Hunn

Mold from rainfall is a big issue in growing alfalfa; it not only reduces the quality of the perennial grass, but it reduces the nutritional value as well. Dairy farmers won’t buy it. “It has really depressed our alfalfa prices.” said Hunn.

On the bright side, rainfall has been beneficial for Hunn’s above-average winter wheat and safflower crops this year. “We had nice rainfall spread out through the whole winter,” he said. “It didn’t come all at one time and flood us out, so that was good.”

Hunn’s hard red winter wheat is drying down in the field, and will be harvested mid-June and sent mainly to flour mills for bread making. The safflower is still growing and looking healthy on a few hundred acres—acres that have been in his family for four generations—and won’t “come off” until late August or September.

Beginning in South Sacramento on 47th Avenue, Larry Hunn’s great-grandfather started farming in the late 1800s, and his grandfather moved to the Delta in the early 1920s, where they’ve been farming ever since. Hunn & Merwin & Merwin Inc. now operates on close to 3,000 acres in Yolo and Sacramento Counties.

Hunn’s other crops have already been contracted with a buyer. “All the cannery tomatoes are in the ground growing, and they look pretty good. We’re in the process of planting cucumbers, that’s just a continuous until the first of August,” mentioned Hunn.

The only disadvantage are the cool breezes from snow atop the Sierra Mountain range that is keeping temperatures low on the cucumbers and tomatoes. Hunn remarked, “I wish it would warm up a little bit. We’re only in the mid-seventies, low eighties, and it would be nice to be up in the mid-eighties or low nineties.”

Overall it’s been a decent year for the veteran Clarksburg grower.
