Helpful Tips for Fighting Bindweed

Multiple Herbicides Can Help with Management

By Mikenzi Meyers, Associate Editor

Field bindweed is continuing to inconvenience farmers and ranchers. However, Scott Stoddard of the UCANR Cooperative Extension in Merced County has some tips on how to control it.

Stoddard explained that the solution isn’t as simple as applying one herbicide, but using a combination might provide some results.

“You have to combine the Roundup with something like a Treflan, and then combine that maybe with some applications of herbicides,” he said.

Stoddard further added that although more successful than applying Roundup alone, even stacking the herbicides will only provide marginal to good control.

The best approach to getting rid of this stubborn weed? Stoddard recommends rotating your field with Roundup Ready varieties so that the herbicide can be more effective on non-Roundup Ready crops.

“For example, a Roundup Ready cotton or corn will clean up a field for the following year for things like tomatoes or melons. In that particular case, Roundup can be very useful,” he said. “Otherwise get it in when you can. If you can apply it before you transplant, or if the bindweed does come out before your transplant that’s when Roundup should be used.”

Pests and Diseases Cause Worldwide Damage to Crops

Pests and Pathogens Place Global Burden on Major Food Crops

By Pam Kan-Rice, UC Agriculture & Natural Resources

Scientists survey crop health experts in 67 countries and find large crop losses caused by pests and diseases

Farmers know they lose crops to pests and plant diseases, but scientists have found that on a global scale, pathogens and pests are reducing crop yields for five major food crops by 10 percent to 40 percent, according to a report by a UC Agriculture and Natural Resources scientist and other members of the International Society for Plant Pathology. Wheat, rice, maize, soybean, and potato yields are reduced by pathogens and animal pests, including insects, scientists found in a global survey of crop health experts.

At a global scale, pathogens and pests are causing wheat losses of 10 percent to 28 percent, rice losses of 25 percent to 41 percent, maize losses of 20 percent to 41 percent, potato losses of 8 percent to 21 percent, and soybean losses of 11 percent to 32 percent, according to the study, published in the journal Nature, Ecology & Evolution.

Viruses and viroids, bacteria, fungi and oomycetes, nematodes, arthropods, molluscs, vertebrates, and parasitic plants are among the factors working against farmers.

Food loss

“We are losing a significant amount of food on a global scale to pests and diseases at a time when we must increase food production to feed a growing population,” said co-author Neil McRoberts, co-leader of UC ANR’s Sustainable Food Systems Strategic Initiative and Agricultural Experiment Station researcher and professor in the Department of Plant Pathology at UC Davis.

While plant diseases and pests are widely considered an important cause of crop losses, and sometimes a threat to the food supply, precise figures on these crop losses are difficult to produce.

“One reason is because pathogens and pests have co-evolved with crops over millennia in the human-made agricultural systems,” write the authors on the study’s website, globalcrophealth.org. “As a result, their effects in agriculture are very hard to disentangle from the complex web of interactions within cropping systems. Also, the sheer number and diversity of plant diseases and pests makes quantification of losses on an individual pathogen or pest basis, for each of the many cultivated crops, a daunting task.”

“We conducted a global survey of crop protection experts on the impacts of pests and plant diseases on the yields of five of the world’s most important carbohydrate staple crops and are reporting the results,” McRoberts said. “This is a major achievement and a real step forward in being able to accurately assess the impact of pests and plant diseases on crop production.”

The researchers surveyed several thousand crop health experts on five major food crops – wheat, rice, maize, soybean, and potato – in 67 countries.

“We chose these five crops since together they provide about 50 percent of the global human calorie intake,” the authors wrote on the website.

The 67 countries grow 84 percent of the global production of wheat, rice, maize, soybean and potato.

Top pests and diseases

The study identified 137 individual pathogens and pests that attack the crops, with very large variation in the amount of crop loss they caused.

For wheat, leaf rust, Fusarium head blight/scab, tritici blotch, stripe rust, spot blotch, tan spot, aphids, and powdery mildew caused losses higher than 1 percent globally.

In rice, sheath blight, stem borers, blast, brown spot, bacterial blight, leaf folder, and brown plant hopper did the most damage.

In maize, Fusarium and Gibberella stalk rots, fall armyworm, northern leaf blight, Fusarium and Gibberella ear rots, anthracnose stalk rot and southern rust caused the most loss globally.

In potatoes, late blight, brown rot, early blight, and cyst nematode did the most harm.

In soybeans, cyst nematode, white mold, soybean rust, Cercospora leaf blight, brown spot, charcoal rot, and root knot nematodes caused global losses higher than 1 percent.

Food-security “hotspots”

The study estimates the losses to individual plant diseases and pests for these crops globally, as well as in several global food-security “hotspots.” These hotspots are critical sources in the global food system: Northwest Europe, the plains of the U.S. Midwest and Southern Canada, Southern Brazil and Argentina, the Indo-Gangetic Plains of South Asia, the plains of China, Southeast Asia, and sub-Saharan Africa.

“Our results highlight differences in impacts among crop pathogens and pests and among food security hotspots,” McRoberts said. “But we also show that the highest losses appear associated with food-deficit regions with fast-growing populations, and frequently with emerging or re-emerging pests and diseases.”

“For chronic pathogens and pests, we need to redouble our efforts to deliver more efficient and sustainable management tools, such as resistant varieties,” McRoberts said. “For emerging or re-emerging pathogens and pests, urgent action is needed to contain them and generate longer term solutions.”

The website globalcrophealth.org features maps showing how many people responded to the survey across different regions of the world.

In addition to McRoberts, the research team included lead author Serge Savary, chair of the ISPP Committee on Crop Loss; epidemiologists Paul Esker at Pennsylvania State University and Sarah Pethybridge at Cornell University; Laetitia Willocquet at the French National Institute for Agricultural Research in Toulouse, France; and Andy Nelson at the University of Twente in The Netherlands.

BioConsortia To Bring New Tools to Ag

BioConsortia Continues Growth and Success, Securing $10 million in Series D Funding

By Patrick Cavanaugh, Editor

Getting even closer to helping California agriculture, BioConsortia, Inc., an innovator of microbial solutions for natural plant trait enhancement and yield improvement, has closed a further round of equity financing to support its continued growth, research achievements, and development of superior products.

Three new PhD scientists working on plants in lab: (from left) Jorge Santiago, Jenna Lang and Steve Wu

The $10 million round was led by Otter Capital and contributed to by Khosla Ventures, both of which are long-term backers of the biotechnology company and experienced ag tech investors.

The completion of Series D will further support the increased momentum BioConsortia saw in 2017, with three strategic new hires, the addition of a sixth U.S. patent, and the planting of fall and winter field trials. Funds raised will be used for the commercial development of a number of novel microbial consortia products — focused toward corn, wheat, soy, tomatoes, and leafy vegetables.

Marcus Meadows-Smith

BioConsortia will also continue to build upon its proprietary discovery process Advanced Microbial Selection (AMS) including supporting the expansion of the AMS platform itself, incorporating deeper and more specialized analytics. Collectively, these steps will drive the company towards the establishment of an original and proven platform for the development of more efficacious and consistent microbial products for a wide range of agricultural crops.

“We are excited by the progress that we have made in product development, for both biostimulants and biopesticides, and the recognition from our investors.” says Marcus Meadows-Smith, CEO. “This new funding allows us to increase our annual spend on R&D, adding more tools from genomics, microbiome and machine learning to our already powerful discovery platform.”

A portion of BioConsortia’s planned development has been and, will continue to be, driven by the key hires made last year: Drs. Jenna Lang and Steven Wu providing scientific leadership in Microbiome Ecology and Computational Biology, respectively. Microbiome analysis and computational modeling underpin BioConsortia’s AMS process. When combined with the extensive physiological data collected throughout the discovery program, microbiome insights enable identification of the functional microbes benefiting high-performing plants, either as individuals or as consortia.

“Collectively, Jenna and Steven have a tremendous wealth of experience and expertise,” says Dr. Sue Turner, Sr. VP of Research. “Throughout the AMS process, we are capturing huge amounts of data; knowing how best to efficiently manipulate and analyze it is crucial for advancing leads and finding new, superior microbial solutions.”

In addition to adding big-data expertise to its research group, BioConsortia has been developing a strong fermentation team as it reaches the final steps in developing leads for commercial launch. Dr. Jorge Santiago-Ortiz joined the company as lead Fermentation Scientist early last year and has worked closely with Dr. Hong Zhu, Sr. VP Lead Development and Manufacturing, to lead scale-up and formulation experimentation in the newly built formulation facilities at the company’s Davis headquarters.

The drive to commercialization is now under way as several microbial treatments transitioned from second and third year field trials across a range of crops and geographies last year. A select number were entered into repeat field trials by major industry players, and these are moving forward to further testing and development. The early-stage biopesticide program also saw many remarkable successes in greenhouse and field trials, and so will be expanded onto many more crops in 2018.

“The expertise that we have added really reflects the comprehensive nature of our discovery and development platform,” Zhu said. “It has set us up for success as we ramp up our 2018 R&D program and move ever closer to product launch.”

Doug Mederos to be Named Tulare’s 57th Farmer of the Year

Doug Mederos to be Tulare’s Farmer of the Year

By Patrick Cavanaugh, Farm News Director

On March 29, the Kiwanis Club of Tulare County will recognize Doug Mederos as the 57th Farmer of the Year. Mederos – a diversified farmer and owner of Doug Les Farms in Tulare County – grows almonds, pistachios, cotton, silage corn and black-eyed peas. Mederos farms 600 acres and manages another 300 acres for his brother.

Mederos told California Ag Today the award caught him by surprise. “It is pretty humbling,” he said, “especially when you see the list of growers they picked [in prior years], and you always wonder, ‘Do I fit in this list or not?’”

Mederos’ family has been farming for several generations. “My grandfather came over in 1920 and started a dairy, P & M Farms, with his brother. When my father got out of the military, he joined the partnership with my grandfather and my uncle and my uncle’s son, Larry Pires.

“Along the way, my two brothers and my cousin’s sister, Loretta, all worked at the farm. My cousin Larry and I eventually became partners in the Pires and Mederos Dairy operation after we graduated from college.

The partners decided to move the dairy out of California and chose South Dakota. Mederos explained, “I stayed here farming in California, and I’ve been pretty fortunate over the years. We’ve had good years and bad years, but the majority of them have been good. Hopefully continuing on so that at some point I get to retire.”

Mederos’ children may continue their family’s legacy of farming in the Central Valley. “Probably my son or somebody will take over,” Mederos said. “He’s going to go off to Fresno State and to major in Ag business, so hopefully in a few years, he’ll be back here. Who knows, maybe it will be my daughter who comes around and ends up running the farm. You never know.”

Tulare County Ag is Down But Strong

Tulare County Annual Crop Report is Down But Still Strong

By Patrick Cavanaugh, Farm News Director

The numbers are in for the 2015 Tulare County Annual Crop and Livestock Report. Marilyn Kinoshita, Agricultural Commissioner/Sealer of Tulare County, reported, “We had an overall value of $6.9 billion, compared to last year, which was more than $8 billion,” which means the County led the nation in total crop value and dairy production, despite a decrease of nearly 14% in one year.

Tulare County’s top ten crops [crop value] in 2015 were:

Milk
Cattle & Calves
Oranges- Navels & Valencias
Grapes
Almonds Meats & Hulls
Tangerines – Fresh
Corn – Grain & Silage
Silage – Small Grain
Pistachio Nuts
Walnuts

Kinoshita explained, “Dairy is our number one industry here. Our milk production was off a little bit. We have fewer dairies in business now because of the low milk prices. Anytime your fresh market milk is off, that’s going to affect our overall value. A good 2/3 of that billion-dollar decrease came from the dairy industry. The price was low the entire year, as opposed to the year before.”

Marilyn Kinoshita, agricultural commissioner, Tulare County

Thus far, the reported 2015 county crop reports in the Central Valley are down this year. “Fresno County, for instance, was down 6.5% off its record $7 billion in 2014,” Kinoshita said.

“It has a lot to do with low water deliveries in Fresno and Tulare Counties,” she continued. “The smaller the water deliveries, the more efficient those growers have to be with that water. Anytime you’re pumping water out of the ground, it’s terribly expensive,” she noted.

“Some of our growers have had to decide, ‘All right, I’ve got this much water; I’m going to keep those blocks alive and I’m going to push an older block that isn’t producing as well.’ The returns aren’t as good as some of the newer plantings,” said Kinoshita.

Despite all of that, Kinoshita said agriculture does sit at the head of the table in Tulare County. “Yes, and we need a successful Ag industry to thrive here,” she said.

Tricia Stever Blattler, executive director of the Tulare County Farm Bureau, noted the crop report demonstrates the strength of the agricultural industry. “I think every year when this crop report comes out, it is always a testament to the resiliency of this industry. This industry takes hard knocks, gets knocked down, then steps right back up to the plate and keeps swinging,” Blattler said. “The agricultural sector has a lot of outside challenges that impact the number that we see reported every year.”

Tricia Stever Blattler, executive director , Tulare County Farm Bureau

Blattler acknowledged the crop value numbers do not reflect net revenue for growers. “It’s always really important for our listeners to know that the crop value is a gross revenue number. When our Ag Commissioner steps to the microphone and speaks to our Board of Supervisors about this report each year, she’s reflecting values that are attributed to all of the gross revenue, and it’s not only the field value,” Blattler said.

“That gross number reported each year also represents our packing houses, our milk processing facilities—the creameries, the butter plants—the packing sheds, all those other parts of our industry that [create] value in our industry,” said Blattler.

Blattler noted up or down, it’s all about the resiliency of farmers. “The industry has its years that are really blockbuster and it has its years when it falls back and we see a reduction acreage. We see reductions in surface water deliveries. The drought is still certainly playing a significant role in the numbers we’re seeing,” she explained.

With regard to surface water, Tulare County is in a bit of a unique position. “As an Eastside county, some of our water deliveries are not as subject to the situation that the Westside is in. In the same sense, we have some significant cutbacks that have been attributed to the San Joaquin River’s restoration and the biological opinions in the Delta—all have had an impact on the Central San Joaquin Valley [water] deliveries regardless of whether you’re Eastside or Westside.

“Also, as the exchange contractors either take greater deliveries of water or give up water, that also impacts the amount available to Eastside growers here in Tulare County,” she said.

In summary, 2015 Tulare Crop Report covers more than 120 different commodities, 45 of which have a gross value in excess of $1 million. Although individual commodities may experience difficulties from year to year, Tulare County continues to produce high quality crops that provide food and fiber to more than 90 countries worldwide.

Nisei Farmers League and African American Farmers of Calif in Sacramento TODAY to Oppose AB 1066

Nisei Farmers League and African American Farmers of California Discuss Disastrous AB 1066 in Sacramento Today

EDITOR’S NOTE: SEE TEDX TALK VIDEO BELOW OF WILL SCOTT, JR., PRESIDENT OF AFRICAN AMERICAN FARMERS OF CALIFORNIA.

TODAY, Manuel Cunha Jr., president of the Nisei Farmers League and Will Scott, Jr., president of the African American Farmers of California are meeting in Sacramento with members of the California Assembly to explain the disastrous consequences of AB 1066, referred to as Agricultural workers: wages, hours, and working conditions, on small and minority farmers.

The effects of this legislation, particularly the Phase-In Overtime for Agricultural Workers Act of 2016, will be detrimental not only to the farmworker who counts on the extra hours, but to the farmer who, with the increasing costs of regulations and the lack of water, will be forced to cut back on crops and their workforce, according to their joint press release.

Manuel Cunha, Jr., president, Nisei Farmers League

“The small and minority farmer will be adversely affected by this ill-conceived legislation,” said Manuel Cunha Jr. “The small farmer works hand in hand with their workforce in the fields and [is] in a better position —with direct input from the workers—to determine schedules rather than politicians in Sacramento looking for a soundbite,” he explained. “Without meeting with our small and minority farmers and farmworkers, these politicians pass legislation that will cost our workforce money, our farmers crops, and the residents of California the fresh fruits and vegetables they enjoy everyday.”

Both Manuel Cunha Jr. and Will Scott believe the Legislators need to consider the small and minority farmers when casting their votes. “We are confident that after we meet with the Assembly members,” said Will Scott, Jr., they will understand how harmful this legislation is to our farmers and farmworkers. It is our hope that by educating the members, they will understand the importance of this bill and vote No on AB 1066.”

Nisei Farmers League

The League continues to inform grower members about ever changing regulations and policies providing legal assistance for labor and workplace related issues. Our leadership and staff maintains a close working relationship with local, state and federal agencies and legislators to assure grower interests are adequately understood and defended.

The NFL also collaborates with other grower and agricultural organizations in both California and other states to help provide a powerful, unified voice for the agricultural community.

Grower members are kept informed through meetings, seminars, newsletters and special bulletins.

Strength, clear focus and growers looking out for growers and farm workers… that is what the Nisei Farmers League is all about.

African American Farmers of California

The Fresno-based African American Farmers of California organization has doubled its membership since it opened a 16-acre demonstration farm in Fresno County, which serves as a testing area where new farmers can get hands-on experience growing a variety of produce.

View Will Scott, Jr. present a TEDx Fruitvale Talk (Uploaded on Oct 20, 2011) Here.

One of Scott Family Farms primary goals is to reintroduce Southern specialty crops, part of the traditional African American diet, into black communities, to help stop the obesity and diabetes epidemics. Crops include: black-eyed peas, crowder peas, purple hull peas, field peas, collard greens, turnip greens, mustard, corn, tomatoes, okra and sweet potatoes.

Mathesius is New UC Soil Scientist

Mathesius is New Agronomy Farm Advisor in Sutter-Yuba, Colusa Counties

By Patrick Cavanaugh, Farm News Director

Konrad Mathesius is the new Agronomy farm advisor at the UC Division of Agriculture and Natural Resources Cooperative Extension, Sutter-Yuba, Colusa Counties. Mathesius first explained his unusual last name. “It means ‘mathematics’ in Latin. I guess we had accountants in our family lineage back there somewhere,” he said.

Mathesius completed his undergrad degree in political science at Utah State, followed by two master’s degrees at UC Davis in Soils and Biogeochemistry; and in International Agricultural Development (IAD)—a graduate group within the Department of Plant Sciences. “The IAD is flexible in its curriculum, which allowed me to take many plant- and soil- specific courses. I took the opportunity at IAD to specialize in soils,” he said.

California Safflower Field

“Through the years, we have learned a lot through the pioneers of soil science and it’s an exciting field because there is still a lot to learn,” said Mathesius. “And everything that comes out of soil science, in one way or another, is applicable to life on the planet.”

“Soils also tell a story, and that’s one thing I really enjoy about it. It’s especially evident in California because there is a remarkable combination of parent material that has created an abundance of different soils in the state,” noted Mathesius. “And it’s very relevant to agriculture, ecology, and environmental science. Differences in soils create a stark contrast in how crops grow and how they need to be managed,” he said.

Mathesius is responsible for the agronomic crops grown in his region, including dry beans, oilseeds such as safflower and sunflower, fresh market corn and silage corn, and small grains such as barley, wheat, and rye.

“I’m a soil scientist by trade, but ultimately I am a UC Cooperative Extension Farm Advisor and available to growers to figure out what their crop issues are—which include pests, diseases and soil fertility,” noted Mathesius. “I am a resource, and the UC system has many other resources and personnel who can thoughtfully consider solutions to crop problems.”

Van Groningen & Sons Adopts Solar

Van Groningen & Sons Becomes Early Adopter of Solar Meter Aggregation

Family owned and operated since 1922, Van Groningen & Sons, Inc. has just completed construction of a 1 Megawatt PV Solar Energy System at their packing, cooling and processing facility located at their company headquarters in Manteca. Designed and installed by Renewable Technologies, Inc. (RTI) of Stockton, CA., the solar system is one of the first to take advantage of the Net Meter Aggregation Policy recently approved by the California Public Utility Commission, allowing for multiple meters to be offset by the production of a single PV solar production system.

RTI worked closely with Paul Hiemstra, warehouse manager at the facility to aggregate 26 electric meters, satisfying the electrical demand of the facility and numerous irrigation pumps across several hundreds of acres of farmland.

The system will generate over 1.4 million kilowatt hours of clean, reliable energy annually and sits atop two large processing buildings. The solar kilowatt hour production will offset approximately 1,034 metric tons of carbon dioxide, the equivalent greenhouse gas emissions produced by 218 passenger cars, the electricity usage of 142 homes or the carbon sequestered by 848 acres of U.S. forest in one year. This project marks yet another step forward in Van Groningen’s efforts toward sustainability, helping to ensure the continuance of the family farming tradition for many years to come.

Van Groningen & Sons, Inc. is closely linked to the growing, shipping and distribution of melons, sweet corn, nuts, pumpkins and fall décor. Their formula is to offer the highest quality products while conducting business with honesty, integrity and responsibility, a recipe that’s certain to last long into the future.

AFT Research Shows Farmland Conservation can Reduce Greenhouse Gases

A new study from American Farmland Trust’s California Office, titled A New Comparison of Greenhouse Gas Emissions from California Agricultural and Urban Land Use [PDF], shows that urban land uses generate an average of 58 times more greenhouse gases per acre than the production of California’s leading crops.

This means that conserving farmland by preventing its development is an effective strategy for alleviating climate change. The AFT research, spearheaded by Steve Shaffer, AFT’s principal environmental consultant in California, found that emissions from seven crops grown on four million acres of the state’s farmland – including rice, tomatoes, lettuce, almonds, winegrapes, corn and alfalfa – averaged 0.89 tons of CO₂ equivalent per acre, while those from residential, commercial and industrial land uses in 13 California cities averaged 51 tons per acre.

“If California farmland conversion could be reduced by half (from 39,500 to 19,750 acres per year), within a decade we would avoid the emission of 55 million metric tons of greenhouse gases,” said Shaffer, “That’s equivalent to taking almost 200,000 cars off the road or driving around the Earth’s equator 5 million times,” he added, noting, “Of course, AFT would like to do even better than that.”
