Strawberries Are A Big Fresh Market Crop

Strawberries Are A big Crop in California

From the end of September through the end of October, strawberries are planted and harvesting occurs from mid- December through mid-July in Ventura County, which produces more than 27 percent of the state’s strawberries. The peak harvesting season in California runs from April through June, when up to 10 million pint baskets of strawberries are shipped daily.

The largest producing state, California harvests 83% of the strawberries grown in the U.S. on approximately 24,500 acres. And with about 5,000 commercial acres, Florida is the second largest producing state. Ideal temperature for strawberry plants should not exceed higher than 78 degrees or lower than 55 degrees.

Every strawberry plant is hand-picked approximately every three days. This is the time in which it takes for strawberries to complete their cycle of turning from green to white to red. There is no storage of fresh strawberries. After picking, they are rushed to coolers where huge fans extract the field heat. Then they are delivered to supermarkets across the country via refrigerated trucks.

Strawberries are the largest available fresh fruit source for vitamin C. Frozen strawberries are America’s largest available frozen fruit source of vitamin C. Versatile and nutritious strawberries are easy to include in school meals and snacks. Low in calories and sugar, strawberries are packed with vitamin C and antioxidants, helping to boost immunity and brain health.

CDFA Celebrates 30 Years with USDA Pesticide Data Program

CDFA Food Safety Scientists Celebrate 30 Years of Continuous Growth Partnering With USDA Pesticide Data Program

The California Department of Food and Agriculture (CDFA) joins the U.S. Department of Agriculture (USDA) in celebrating the 30th anniversary of the Agricultural Marketing Service Pesticide Data Program (PDP). CDFA’s Center for Analytical Chemistry (CAC) Food Safety group has partnered with PDP since its inception in 1991.

PDP is a federal partnership with nine states that monitors pesticide residues in the U.S. food supply. PDP data helps demonstrate the high quality of the U.S. food supply — analyses show that pesticide residues are lower than the limits established by the U.S. Environmental Protection Agency in nearly all food samples (typically >99%).

The partnership between the agencies started with a screening list of 28 pesticide compounds. It has since expanded the scope to detect and quantify more than 515 compounds.

Partnering in this project has helped the CAC Food Safety program model its quality system framework into one that generates the highest-quality data for enforcement and regulatory purposes. Innovation was fostered through CAC scientists applying novel analytical methods and custom-made software to automate data processing and review.

“These endeavors opened doors to continuous technical improvement and enabled us to significantly increase our capability to generate high-quality, defensible data in a fast-turnaround work environment,” said CAC Environmental Program Manager Tiffany Tu. “The benefit gained from collaborating with other agencies in the pesticide analysis field in impactful scientific projects helped further our goal of being in the forefront of the pesticide analysis arena, which also ensures CAC Food Safety program’s relevance in our mission of promoting and protecting California agriculture.”

Brandon Crosson Earns Top Honors in Young Farmers and Ranchers Discussion Meet

Modesto Junior College student wins in Farm Bureau’s Collegiate Discussion Meet

Braden Crosson, an intern in the Modesto Junior College School of Agriculture’s crop unit, has won the 2021-22 California Young Farmers and Ranchers Collegiate Discussion Meet.

Crosson, of Galt, emerged as the winner of the competition finals, held in Bakersfield on Nov. 13. The event featured a policy discussion on the long-term viability of livestock processing following the COVID-19 pandemic.

In his winning presentation, he addressed how California Farm Bureau efforts can lead to easing government regulations to enable long-term economic viability for local animal processing facilities, while also protecting workers and ensuring that healthy products are delivered to consumers.

As the winner of the contest, he receives $1,250 and will now represent California in the national competition held in February 2022 during the American Farm Bureau Federation’s Young Farmers and Ranchers Conference in Louisville, Kentucky.

The competition, part of the Farm Bureau’s Young Farmers and Ranchers Program, simulates a committee meeting, in which each committee member is expected to actively participate in a policy discussion. The idea is for participants to improve their discussion skills while learning about important agricultural issues. Ultimately, they learn to work in groups to pool knowledge, reach consensus and solve problems.

Water Supply At Risk From Wildfires

How Can California Protect its Water Supply From Wildfire?

By Pam Kan-Rice UCANR Assistant Director, News and Information Outreach

Stakeholders from across disciplines and institutions offer recommendations to ensure safe, reliable water supply amid a growing wildfire threat

It’s intuitive that wildfires can affect ecosystems, harm wildlife and contaminate streams and rivers. But wildfires can also have complex, severe and direct effects on our water supply and infrastructure—effects that have only become clear in recent years. Scientists and policymakers must integrate insights and experience from many disciplines and sectors to understand and address the consequences.

In September, 23 scholars and practitioners with a diversity of water and fire expertise came together to answer a critical question: How can California proactively protect its water supply from fires? Their findings, combined with the insights of the author team, form the basis of a new scoping report, released by the University of California Division of Agriculture and Natural Resources’ California Institute for Water Resources and the UCLA Luskin Center for Innovation.

“Different people have different pieces of the puzzle, but it’s really hard to put them together. That is why we assembled this cross-sector group,” said Faith Kearns, academic coordinator at the California Institute for Water Resources.

Illustrated by the 2017 Tubbs Fire in Wine Country, it has been recognized that community water systems face effects that last long after the fire is quenched. For example, Boulder Creek residents in Santa Cruz County still did not have reliable water access more than a year after firefighters extinguished the 2020 CZU Lightning Complex Fire.

“This is truly an emergent issue,” said co-author Peter Roquemore, project manager at the Luskin Center for Innovation. “We have only seen wildfires directly affect community water systems in the past few years.”

To help California policymakers, researchers, affected communities, and water system operators understand the complex relationship between wildfire damage and water supply, the report authors and participants in this workshop present a set of recommendations:

Make communications more accessible, consistent and trustworthy. Residents must receive timely, unified messaging, translated into appropriate languages and in accessible venues, telling them if their water is unsafe and how to access clean water.
Invest in local capacity and expertise. The challenges faced vary widely for different communities, and it is important to provide each community with the resources it needs to address the risk it faces. As part of this, efforts should support Indigenous leadership, knowledge and practices to help manage healthy ecosystems.
Provide guidance to update regulations. Guidance such as building codes and infrastructure regulations will help individuals and communities make informed decisions and address risk appropriately.
Conduct research and build a broader base of knowledge. There is still much to learn, and it is important to illustrate the exact challenges water systems face and how best to address them.
Make funding accessible and targeted. Increased earmarked funding for emergency water supplies, housing assistance, and support for water systems, local organizations, and others will help advance solutions.
Further coordinate efforts to address water and fire issues. Focusing on these interconnected issues together, rather than tackling them separately, can lead to substantial benefits.

To read the specific recommendations identified, read Wildfire and Water Supply in California. Funding for this research was provided by the U.S. Geological Survey through the California Institute for Water Resources.

Important COVID Prevention at Almond Industry Conference

Almond Industry Conf. Offers Before-You-Go-Tips

Big Event will he at the SAFE Credit Union Convention Center

It’s almost here! The Almond Conference is just around the corner and we are looking forward to gathering in-person with our friends and colleagues in the almond industry. When the Board of Directors made the decision to move forward with an in-person conference at our meeting in June, we knew it would be a challenge given State of California restrictions on large indoor gatherings. We knew there was a risk in moving forward with planning when we could get the rug pulled out from under us at any time, but we felt the benefits of meeting in person outweighed the risks and voted unanimously to move forward.

Now here we less than one week out and we are full speed ahead! More than 3,000 industry members have pre-registered to join us in downtown Sacramento on Dec. 7-9. A record number of exhibitors will be arriving this weekend to set up for the largest trade show The Almond Conference has ever assembled. And staff have put together a tremendous lineup of educational sessions, keynote speakers and world-class entertainment!

In order to meet in person we must meet the State requirements for “mega events” (more than 1,000 people indoors). This includes requiring attendees to provide proof of vaccination or a negative COVID test taken within 72 hours of arriving in Sacramento. This is a State of California requirement, not an Almond Conference policy (these are the same restrictions that are in place to attend a Kings game at the Golden One Center). We understand this is an inconvenience and have tried to make it as easy as possible to provide this information so we can hold the event in person. See below for more information.

Also, at this time, the County of Sacramento requires masks be worn indoors in public spaces, including the Convention Center. Sacramento County’s Public Health Department will end their indoor mask requirement if the count reaches 5 or fewer cases per 100,000. We’re watching the numbers closely and currently Sacramento is on a downward trend at around 10 cases per 100,000. We are hoping the downward trend continues as we know many of you would prefer not to wear masks in the facility. We will update you if the County lifts the requirement. If not, you will need a mask to enter the Convention Center.

We appreciate everyone’s understanding and assistance as we navigate the various State and Local requirements to hold The Almond Conference in person. We hope you’ll agree that the opportunity to meet in person is worth it! Thank you for your patience and we’re looking forward to seeing you next week in Sacramento.

Reducing Food Waste by Creating Other Good Food

UC Master Food Preservers Turn Food Scraps Into Gifts Dec. 1

By Pam Kan-Rice, UCANR Assistant Director, News and Information Outreach

Free online class offers recipes for using food scraps, answers questions about food preservation

“Putting food in our bellies instead of landfills is good for the planet,” said Sue Mosbacher, University of California Master Food Preserver Program coordinator. In landfills, decaying food releases methane, a greenhouse gas that contributes to climate change.

“We can reduce food waste and save money by creating new foods from food scraps,” Mosbacher said. “Instead of throwing away a lemon peel after squeezing out the juice, use the lemon zest to make lemon curd or citrus salt. They make wonderful homemade gifts for the holidays.”

UC Cooperative Extension Master Food Preservers, a program of UC Agriculture and Natural Resources, provides ideas for using leftovers and advice for safely preserving food.

On Dec. 1, 6:30 to 7:30 p.m., UCCE Master Food Preserver volunteers of Amador and Calaveras counties will host a free online class to show samples of apple honey, citrus salt, strawberry vinaigrette, sugared walnuts and lemon curd. Recipes will be emailed to participants.

“Many of these gifts are inexpensive to make because you’re using food scraps – such as lemon rind or apple peel – and a few other ingredients. You can put the citrus salt in jars you’ve saved,” Mosbacher said. “It is easy to make and there’s no special equipment needed.”

After the “show and tell” session, the UCCE Master Food Preserver volunteers will answer participants’ questions about freezing, dehydrating and canning foods and food safety.

Because the class is online, anyone can participate, regardless of their location. Register for the one-hour Zoom class at https://mfp.ucanr.edu/Events/?calitem=516566.

The UCCE Master Food Preserver Program extends UC research-based information about home food safety and preservation to the public throughout the year. UCCE Master Food Preserver volunteers are located in 19 counties of California, most recently certifying volunteers in Modoc County, where they are offering pressure canner testing.

UCCE Master Food Preserver volunteers host monthly workshops on the first Wednesday of each month, with hosting duties rotating between Sacramento, El Dorado, Amador and Calaveras counties.

For 2022, the UCCE Master Food Preservers of Sacramento County are planning to offer the following workshops via Zoom:

Jan. 19 – Citrus for Super Bowl
Feb. 16 – Dehydration for Soups
March 16 – Soups & Roots
April 20 – “Night of Fermenting” Cheese/Yogurt/Sauerkraut
May 18 – Jams & Jellies
June 15 – “Ready for BBQ Season” Condiments & Beverages
July 20 – Red, White & Blue
Aug. 17 – “Tomato Mania” Salsas, Sauces & Peppers
Sept. 21 – Sausages & Mustards
Oct. 19 – “Apples, Pears & Persimmons Oh My”
Nov. 16 – Sides Dishes for your Holiday Dinner
Dec. 21 – Quick Gifts

Aubrey Bettencourt Will Head up Almond Alliance

Almond Alliance of California Names Aubrey Bettencourt as President/CEO

The Almond Alliance of California (AAC) has named Aubrey Bettencourt as its new President and CEO. She currently serves as Director for Sustainability for the California Cattle Council and Western United Dairies and has extensive experience dealing with a wide range of California agricultural and natural resource issues.

Bettencourt succeeds Elaine Trevino, who has been nominated by President Biden to be the Chief Agricultural Negotiator for the U.S. Trade Representative. Trevino is awaiting a confirmation hearing before the U.S. Senate Finance Committee.

Almond Alliance Chairman Mike Curry said Bettencourt’s selection came after an extensive and thorough executive search. Curry commented, “We are extremely excited to have Aubrey Bettencourt as the Almond Alliance’s new President and CEO. Aubrey comes to us with a wealth of diverse knowledge and innovative advocacy work on behalf of farmers and ranchers. As the California State Director of the USDA Farm Service Agency, she fought to keep ‘farmers farming’ through the delivery of effective and efficient agricultural programs.

Serving as Deputy Assistant Secretary in the Water and Science Division of the U.S. Department of the Interior, Bettencourt developed and coordinated national water and science policy, expanding her extensive knowledge of state and national water issues and available resources, making her a unique asset to our membership and community.” Curry added, “Aubrey’s work as the director of the statewide non-profit, California Water Alliance, has given her the tools necessary to advocate for our members as the water crisis in California becomes even more complicated.

As the Director of Sustainability for the California Cattle Council and Western United Dairies, Bettencourt has focused on water supply and water quality, forest health and fire prevention, carbon sequestration, climate resiliency and ground water sustainability. Raised in a farming family, Aubrey has firsthand knowledge of what it takes for a family farm to survive in California and beyond.” “I am excited to join the Almond Alliance, a dynamic leader in American agriculture,” Bettencourt said. “As a fourth generation California farmer, it is a personal honor to serve. I look forward to working with this team to keep farmers and processors providing economic opportunity to our rural communities, bringing worldwide the highest quality product from our farms to your table.”

Bettencourt noted, “The California almond farmer is the most sophisticated in the world; leading in technique, technology, sustainability, safety, and quality. We take pride in this role and great responsibility in this legacy. The challenges we face as an industry including water, labor, energy, supply chain, and climate change, are opportunities for our continued leadership and advocacy. Rather than reacting, we will lead with our own achievable, common-sense solutions to these challenges for the continued success of our farmers, our communities, our businesses, our environment, and our consumers.” Curry noted that in her three years at the helm, Trevino led the almond industry through some very challenging times and wished her the best in her new position.

“I am so incredibly excited for Elaine and her nomination by the President to be the next Chief Agricultural Negotiator at USTR,” Curry commented. “As the President and CEO of The Almond Alliance, Elaine has led our industry through very difficult times. From trade wars, labor issues, struggles during the pandemic, to port issues, Elaine has been a fierce leader fighting the good fight. In every step of the way she has done the good work for California. Yet, Elaine has always kept the communities of our members at top of mind, knowing the economic impact the almond industry has on so many California communities. Elaine has been a true advocate for the good of all. Elaine is the type of leader with the focus to leave things better then she found them.” Looking ahead to her new role, Curry said, “There is no doubt in my mind that as the Chief Agricultural Negotiator, Elaine will continue to be the person who adopts real solutions to real problems.

The United States agricultural community has gained a true problem solver in Elaine Trevino. “ Elaine thanked Almond Alliance members and partners for their support over the past three years. “It has been an honor to work for the Almond Alliance,” she said. “Together we took the Alliance to new heights and strengthened the voice of almonds in Sacramento and Washington DC. Thank you for the opportunity you have given me to lead one of the best agricultural associations in the country. I look forward to staying in touch and learning about the Almond Alliance’s future successes.”

Bettencourt will assume her new role on December 1, 2021 and will work out of the Alliance’s Modesto office.

2019 Biological Opinion Lawsuit Grows

Ag Groups Weigh in on 2019 Biological Opinion Lawsuit

American Pistachio Growers, along with agricultural organizations, signed a letter to the Honorable Deb Haaland, Secretary U.S. Department of Interior, and the Honorable Wade Crowfoot, Secretary Natural Resources opposing new court filings in California’s lawsuit challenging the 2019 Biological Opinions on water projects.

The joint agricultural letter reads as follows:
We are opposed to new court filings in California’s lawsuit challenging the 2019 Biological Opinions for coordinated operations of the federal Central Valley Project (CVP) and the State Water Project (SWP). These filings include an unprecedented and unvetted interim operations plan for the upcoming water year in California.

As we have known – and has been highlighted over the last year and a half – facts and findings grounded on science need to be followed. That ethos should also apply to the coordinated operations of the CVP and SWP.

We support continued efforts by your respective departments to work collaboratively to manage the operations of California’s major water infrastructure. California communities are in desperate need of relief. Many of our most disadvantaged communities are lacking reliable, clean drinking water.

In addition, Groundwater Sustainability Agencies are expediting enforcement actions to minimize negative impacts resulting from groundwater overdrafts. We implore you to work together to alleviate these extreme circumstances, rather than exacerbate them.

We are willing to help provide solutions, along with bringing interested parties together to help the communities where we live, work, and grow to stay alive. Only by fostering partnership among all levels of government and among interested parties can we resolve California’s short- and long-term water issues.

UC Davis Doctoral Candidate Wins High Honors at ESA Meeting

Doctoral student Danielle Rutkowski of the UC Davis Department of Entomology and Nematology received the President’s Prize in her category for her research presentation at the recent Entomological Society of America (ESA) meeting in Denver.Rutkowski delivered her 10-minute presentation on “Fungicide Impacts on Bumble Bees are Mediated via Effects on Bee-Associated Fungi” in the category, Plant-Insect Ecosystems: Ecology 3.” She studies with community ecologist Rachel Vannette, associate professor, and is also advised by community ecologist and professor Rick Karban.

At the ESA’s annual meetings, students are offered the opportunity to present their research and win prizes. They can compete in 10-minute papers (oral), posters, or infographics. First-place winners receive a one-year free membership in ESA, a $75 cash prize, and a certificate. Second-winners score a one-year free membership in ESA and a certificate.

Rutkowski’s abstract:

“Native bees including bumble bees are important pollinators but face threats from multiple sources, including agrochemical application. Declining bumble bee populations have been linked to fungicide application, which could directly affect the fungi often found in the stored food and GI tract of healthy bumble bees. Here, we test the hypothesis that fungicides impact bee health by disrupting bumble bee -fungi interactions.

Using two species, Bombus vosnesenskii and B. impatiens, we test the interactive effect of the fungicide propiconazole and fungal supplementation on the survival, reproduction, and microbiome composition of microcolonies (queenless colonies). We found that both bee species benefitted from fungi, but were differentially affected by fungicides.

In B. vosnesenskii, fungicide exposure decreased survival while fungal supplementation mitigated fungicide effects. For B. impatiens, fungicide application had no effect, but fungal supplementation improved survival and offspring production. Fungicides altered fungal microbiome composition in both species, and reduced fungal abundance in B. vosnesenskii microcolonies, but not in B. impatiens, where instead fungal addition actually decreased fungal abundance.

Our results highlight species-specific differences in both response to fungicides and the nature of fungal associations with bees, and caution the use of results obtained using one species to predict the responses of other species. These results suggest that fungicides can alter bee- fungi interactions with consequences for bee survival and reproduction, and suggest that exploring the mechanisms of such interactions, including interactions within bee-associated fungal communities, may offer insights into bumble bee biology and bumble bee conservation strategies. (Paper co-authors are associate professor Rachel Vannette, Eliza Litsey and Isabelle Maalouf)

Rutkowski completed her bachelor’s degree at Cornell University, where she studied how the relationship between mycorrhizal fungi and their host plants impacts insect herbivores. She currently studies “how bumble bees interact with the microbes, particularly fungi, in their environment, and how these relationships impact bee health.”

Two other UC Davis graduate students won second-place honors in their respective categories.

Maureen Page with the lab of pollinator ecologist Neal Williams, professor, UC Davis Department of Entomology and Nematology, scored second place for her presentation, “Optimizing Pollinator-friendly Plant Mixes to Simultaneously Support Wild and Managed Bees.” She competed in the category, Plant-Insect Ecosystems: Pollinators.

Kyle Lewald, with the College of Biological Sciences and the Integrated Genomics and Genetics Graduate Group, but a member of the lab of molecular geneticist and physiologist Joanna Chiu, professor and vice chair of the UC Davis Department of Entomology and Nematology, won second in his category, Systems, Evolution and Biodiversity: Genetics and Molecular Biology, with his speech on “Assembly of Highly Contiguous Diploid Genome for the Agricultural Pest, Tuta absoluta.”

ESA, founded in 1889 and headquartered in Annapolis, Md., is the world’s largest organization serving the professional and scientific needs of entomologists and others in related disciplines. Its 7000 members are in educational institutions, health agencies, private industry, and government.
