Giving Tuesday Big for UC

Giving Tuesday Donations Exceed UC ANR Expectations

By Pam Kan-Rice, UC Agriculture & Natural Resources

On Giving Tuesday 2019, donors gave $130,311 over 24 hours for UC Cooperative Extension, statewide programs and research and extension centers that make up the University of California Agriculture and Natural Resources network.

The donations will help UC Agriculture and Natural Resources extend the power of UC research in agriculture, natural resources, nutrition, and youth development to more Californians in their own communities to improve their lives.

“The generosity of our donors will help us keep 4-H leadership-building activities affordable for California kids, and fund research into living with wildfire, farming in a changing climate, healthier foods, pest control for home and environment, and many other issues that concern Californians,” said Glenda Humiston, UC vice president for agriculture and natural resources.

“UC ANR researchers and educators are working in every county to bring practical, science-based answers to residents wherever they live in the state,” noted Humiston.

Thanks to generous donors, volunteers, staff and board members who gave a total of $40,000 in matching funds, there was an incentive for donors across the state who wanted to double the impact of their gifts.

“We set a goal of collecting a total of $125,000 for 4-H and UC ANR from more than 500 donors on Giving Tuesday,” said Emily Delk, UC ANR director of annual giving and donor stewardship. In all, UC ANR received 580 donations on Giving Tuesday.

Donations are still being accepted to boost UC ANR programs and research for a healthier California. To give, visit http://donate.ucanr.edu.

Four Students Selected to Represent Real California Milk in Asia, Mexico

Student Ambassadors Share California Dairy Message with International Audiences

News Release

The California Milk Advisory Board (CMAB) has selected four students to serve as interns in the second year of the international dairy leadership program. Jessica Brown, Stefani Christieson, KayCee Hartwig-Dittman and Makayla Toste will serve as dairy representatives, working with marketing teams representing CMAB during the summer in Mexico, South Korea and Taiwan.

The interns, selected from students enrolled in agriculture-related programs at colleges and universities throughout the state, were chosen based on academic achievement, connection to the dairy industry, and a willingness to travel abroad and learn more about international dairy sales and marketing as well as a plan to work in the California dairy industry in the future.

Over the six-week period, each intern will spend time with in-country CMAB marketing organizations—Brown in Taiwan, Christieson and Hartwig-Dittman in South Korea and Toste in Mexico—to gain a better understanding of these markets, consumer buying habits, and promotional efforts on behalf of California’s dairy industry.

Brown is currently enrolled at Fresno State, majoring in agriculture business. She was raised on her family’s vineyard in Tracy and has always had a passion for agriculture. Her desire to learn about agriculture outside of the U.S. has provided her with opportunities to study abroad, most recently in Spain. Because of her love of travel and learning about other cultures, Jessica is focusing on international marketing at college, with plans to work in this field of study upon graduation in 2020. Brown is a member of the agriculture marketing team at Fresno State and will be working with Steven Chu and Associates in Taipei, Taiwan.

Christieson is a recent graduate of the UC Davis, where she received her B.S. in Political Science and minors in economics and French. She will be attending graduate school in the fall at Sciences Po in Paris, France, for a year and then will complete the program at Fudan University in Shanghai, China in year two. Christieson plans to complete her master’s degree in international economic policy and pursue a career as agriculture economic policy advisor for an agriculture export market organization to help California farmers continue to expand into emerging and established markets overseas. Christieson will be working with Sohn’s Market Makers, Ltd. in S. Korea.

Hartwig-Dittman is currently enrolled at Fresno State, where she is majoring in dairy science and is employed at the dairy unit on campus. She has a culinary arts degree from Diablo Valley Community College and has experience working in the restaurant industry in California. Her love of travel and food has allowed her to travel outside of the U.S., where she has learned to use dairy products in new and creative ways with hopes to find innovative ways to introduce dairy to consumers around the world. Hartwig-Dittman will also be working with Sohn’s Market Makers, Ltd. in South Korea.

Toste, a second-generation dairy farmer from Newman, received her B.S. degree in Animal Science with an emphasis in dairy science. During her last year at Fresno State, Toste served as the assistant herdsman for the Fresno State dairy unit, where she was responsible for the day-to-day operations of the dairy and an officer for the Fresno State Dairy Club. After the internship, she plans to work in the California dairy industry in promotion and marketing to help keep the industry viable for the next generation of farmers. Toste will serve as an intern with the team at Imalinx in Cuernavaca, Mexico.

“California accounts for more than 33 percent of all U.S. dairy exports so international trade is essential for our continued growth. Over the last decade, the CMAB has worked closely with partners in Asia and Mexico to develop markets for California dairy products. This program is focused on providing insight into international dairy marketing for future leaders like Jessica, Stefani, KayCee, and Makayla, who will work in the dairy business and one day serve on dairy industry boards and lead industry groups,” said Glenn Millar, Director of International Business Development for the CMAB.

The goal of the CMAB International Internship program is to provide agriculture/dairy college students an opportunity to learn about dairy foods and marketing in the international marketplace. The program looks to develop leaders who will serve on dairy industry boards and work in dairy foods production, processing, or sales/marketing.

Delta Smelt Are Poor Swimmers, Unlikely to Reach Pumps

How Many Smelt Are Actually At the Pumps?

By Kristi Diener, Fourth Generation San Joaquin Valley Farmer

Delta smelt are poor swimmers. When they have to swim against voluminous outflows, they struggle. They also lack endurance for distance and swimming against currents. This was the result of the taxpayer-funded swim performance test conducted more than 20 years ago. Why is this important?

Delta smelt live in the freshwater/saltwater mixing zone made up of outflow from the fresh waters of the Sacramento and San Joaquin Rivers, and the inflow of saltwater pushed towards that freshwater from the ocean tides. Smelt leave this mixing zone in search of freshwater to spawn, in the late winter to early spring. It is the same time of year when the outflows from the Sacramento and San Joaquin Rivers are at their peak. Recently, water surging out from the rivers was equal to 104,900 basketballs per second!

If the smelt are able to swim against these powerful outflows, they don’t go too far, and generally spawn pretty close to the nearest region of freshwater they can find in the delta. However, most smelt being surveyed during spawning are not in the delta at all, rather, in the much smaller waterways to the north where there is a fraction of the freshwater outflow. Twenty-one years ago, UC Davis acknowledged outflows from the Sacramento and San Joaquin rivers are actually too high for the endangered smelt!

Let’s jump to the “pumps.” They are about 60 miles away from where smelt live in the mixing zone of the Suisun and San Pablo Bays. The pumps capture water at the south end of the delta, where it later flows into storage at San Luis Reservoir. Eventually, it is conveyed south to 2/3 of the state.

Water that is not captured by pumping surges out from the Sacramento and San Joaquin Rivers into that mixing zone. These pumps are routinely throttled back because, according to the Smelt Biological Opinion, smelt are in danger of getting sucked-in and killed. The result of not pumping is huge losses of water for human use and huge increases of outflow from these two rivers into the ocean.

So how many smelt, who lack endurance for long swims according to the swim performance test, are actually surveyed near the pumps and at risk of being liquidated? Every month, a trawl survey is conducted to count smelt and find out where they’re hanging out. I pulled up the fish distribution maps for every monthly trawl over a 10-year period. The closest a smelt has been surveyed near the pumps is about 30 miles away from them, seven years ago.

Still, in spite of their own swim performance tests, the opinion is that smelt swim about a 60 mile, squiggly endurance course, destined for the pumps. Remember, they spawn in freshwater, but actually, live back in the mixing zone where they must return. Nonetheless, this opinion is the very hypothesis that ratchets back pumping at full capacity and prevents the securing of water for humans. There are many other facets of the opinion that are questionable as well. Incidentally, just two smelt have been surveyed anywhere in the last 10 months.

Here’s the good news. President Trump signed an executive memo in October, requiring the Biological Opinions to be reviewed and updated. The science is well over a decade old. Please notice it is called an “opinion”, not a fact. Trump set a timeline and a deadline to get it done too. The assessment phase had to be completed by January 31, and it was. The deadline for the new Opinions to be issued is 135 days after the assessment, which I calculate to be around June 15th. I’m counting.

In the next couple of months, we’ll likely be hearing a whole bunch of malarkey coming from the folks favoring water for the sea in the name of fish, instead of for humans and the earth. There will be an uproar when the Biological Opinions are revised to actually help endangered fish, instead of being used as a vehicle to implement an agenda of man-made water shortages, more regulations, increased fees, and new taxes. You will hear misinformation, but you will know the truth.

CDFA To Hold Good Ag Neighbors Workshops

Workshop Designed for Produce Growers and Livestock Areas to Promote Food Safety

News Release

In order to facilitate dialogue between different sectors of California agriculture about cooperation to prevent future foodborne illness outbreaks, the California Department of Food and Agriculture (CDFA) is partnering with the University of California and the U.S. Food and Drug Administration (FDA) to bring the livestock and produce communities together for a series of workshops.

The workshops, titled Good Ag Neighbors, are designed for fruit and vegetable growers, livestock owners, and others interested in learning about how produce safety and livestock management practices can work jointly to promote food safety.

The workshops will be held in two California locations, with the first scheduled for June 11 from 9 a.m. to 4 p.m. at the Desert Research and Extension Center in Holtville. The second workshop is scheduled for June 13 from 9 a.m. to 4 p.m. at the Robert J Cabral Ag Center in Stockton.

“Agriculture is complex,” said CDFA Secretary Karen Ross. “This is particularly true in California, where diverse agricultural operations often exist side-by-side, with each of them required to comply with a myriad of regulations designed to protect the public, the environment, and the food supply.”

Karen Ross, CDFA Secretary

Diversity is extremely important to the fabric of California agriculture. Also important is open communication channels between diverse partners. This has become more apparent with the CDFA’s newly created Produce Safety Program, which is working on behalf of the U.S. FDA to enforce produce safety regulations under the Food Safety Modernization Act.

The workshops will address lessons learned from recent investigations of produce-related foodborne illness outbreaks, examine key research findings, and consider future research needs.

The workshops are being conducted by the UC Davis Western Institute for Food Safety and Security and will include presentations by researchers and industry representatives. The day-long agenda will focus in the morning on reviewing regulations, laws, and practices already in place to protect food and environmental safety, while the afternoon will be spent in various breakout groups examining how these practices can be leveraged.

Participants should come prepared to share their experiences as well as their produce safety questions.

The workshops are offered free of charge. For more information and to register, please visit http://www.wifss.ucdavis.edu/good-ag-neighbors/.

Tulare Center Trains UC Davis School of Veterinary Medicine Students

UC Vet Students Learn About Livestock Animals in Tulare

By Patrick Cavanaugh, Editor

VMRTC is the Veterinarian Medicine Training and Research Center located in Tulare. The facility is an extension of the UC Davis School of Veterinary Medicine. The site offers education and training to veterinarians by offering senior veterinary students and residents on-the-farm clinical medical training and residencies in dairy production medicine.

Nathan Brown, a UC Davis veterinary student, is working on practicals in and out of a hospital setting.

“We do rotations in the hospital and outside of the hospital. We have a teaching center and, in addition, we have our California Animal Health and Safety Laboratory System (CAHFS), which is involved with diagnosing foreign animal diseases,” Brown said. “That is sort of the main mission.”

“In the mornings, we do herd checks, we go out to different dairies. We palpate cows for diagnosis of pregnancy, and we’re under the supervision of some of the veterinarians that work at our center,” Brown explained. “In the afternoons, we work on a variety of different projects. One of the projects that we’re working on currently is milking frequency. We are looking at different variables that go into whether or not it’s profitable to move from either two to three times a day or three times a day to two times a day.”

Brown said that the students at the Tulare center are doing their livestock track through UC Davis. “We’re all in our fourth year. It’s been a wonderful experience. Tulare is a great place, and it’s good to see a different part of California.”

Students studying at the center decide which direction they will take regarding animal type or other medical pursuits.

“After our second year, we make a decision about whether we do small animals or large animals,” Brown said. “Some people do equines, other focus on zoo animals—there is a variety of options in our profession and that our school offers.

Brown is pursuing livestock medicine, but he has a commitment to the Air Force to do public health epidemiology for them.

Army veterinarians do clinical medicine for animals on the base. They focus on German shepherd dogs and horses, and they also do some food safety.

“As as a veterinarian in the Air Force, it’s essentially veterinary public health, and my role will be epidemiology on a base, so that’s actually more human focus, and food safety,” Brown said.

“If you kind of think about the historical roots of veterinary medicine, much of the role of veterinarians has been ensuring that food is safe for humans to consume, meaning that the animals are healthy before they get ready for human consumption,” Brown explained. “We must ensure that there’s no points of contamination so that all the food that people eat in this country is healthy and nutritious, and we don’t have to worry about disease.”

Most bases have a veterinary clinic, primarily staffed with army veterinarians.

“My hope is to do some amount of clinical practice at these clinics to sort of keep my veterinary skills relevant. And I’ve had some good advice from some epidemiologists who works at the CDC,” Brown said. “He told me that at least for him, it’s made him a better epidemiologist by keeping his clinical skills relevant because thinking about that differential diagnosis is really a big part of trying to find the cause of a disease.”

Weedy Rice—Not as Simple as it Sounds

Weedy Rice is A Pesky Rice Type in Production Rice Fields

By Mikenzi Meyers, Associate Editor

Contrary to its name, weedy rice is not in fact weeds in rice—but it is presenting several challenges to California rice growers. To help farmers combat the pesky variety, UC Davis Ph.D. student Liberty Galvin and the horticulture and agronomy graduate group have conducted extensive research.

According to Galvin, the genetic and physiological properties of weedy rice are the same as the cultivated varieties consumers typically eat. So what’s the issue? Galvin said that besides the fact that weedy rice is off in its coloring, it’s nearly impossible to harvest.

“The issue is that the seed shatters, or basically falls to the ground. So when you go through and try to harvest it, the grain does not get collected in the harvester,” Galvin explained.

Although right now it seems that commercially growing weedy rice is not an option, there are ways to prevent it. Galvin’s research found that drilling the seeds at least two inches into the soil will eliminate seed germination or emergence in the field. This is especially useful in California, where tillage is done only to prepare the field, not plant the rice itself.

Galvin said that while growers can produce their own rice seed, it has to be certified by the California Crop Improvement Association or a Rice Seed Quality Assurance Program. In all cases, growers are required to plant only certified rice seed so there is no opportunity for traces of weedy rice to enter the soil.

“That is why tillage depth is so important, because that’s how you reduce your seed bank,” she said.

More Facts About the “Dirty Dozen” List

New So-called “Dirty Dozen” List is Baseless

News Release

To everyone that has read about the “Dirty Dozen” list and is now confused and conflicted about buying the more affordable and accessible fruits and veggies, this blog is for you. Keep in mind that the “Dirty Dozen” list is designed to make you worry and be fearful. After all, fear is a very powerful motivator, and the list authors attempt to increase safety fears to motivate and influence consumers’ produce buying decisions.

So here are some facts about the “Dirty Dozen” list that underscore you can consume either conventional or organic produce with confidence. Both are safe, and the right choice is to eat more every day.

Arbitrary Methodology: According to Dr. Carl Winter, toxicologist, University of California, Davis.: “This year’s EWG list is produced using the same arbitrary methodology the EWG has used in the past. Most importantly, the EWG focuses upon the presence (or absence) of pesticide residues in its methodology and public statements rather than on the actual amounts of pesticides detected, which are extremely low. To accurately assess consumer risks from pesticides, one needs to consider three major factors – 1) the amount of residue on the foods, 2) the amount of food consumed, and 3) the toxicity of the pesticides. The methodology used by EWG ignores all three.”
Meet Organic Standard: Did you know that the vast majority of conventionally grown produce tested by United States Department of Agriculture could qualify to be labeled “organic,” specific to their residue levels? It’s true. The USDA allows organic produce to have residues that are “less than 5% of EPA tolerances” and the majority of residues found on conventionally grown produce are below this level. This nicely illustrates how low residues are, if present at all.
You Can Eat A Lot of Kale: If you are concerned about residues on kale, you would have to eat a lot more each day to see any health effects. In fact, a man would have to eat 26,061 servings in a day.. Click here to continue reading and to like and share this blog post.

Cover Crops in Almonds Can Displace Annual Winter Weeds

Steve Haring Working With UC Davis on Cover Crops

By Mikenzi Meyers, Associate Editor

Depending on your location, cover crops can have a big impact on your fields. Steve Haring, second-year Ph.D. student in the Department of Plant Sciences at UC Davis, has been collecting research on how different climates influence the effectiveness of cover crops.

Almond Cover Crop Displacing Weeds

“As we try to design cover crops, there are a lot of different paths we can take, and it’s important to test these different things out and see what is best for the specific things we can use cover crops for in the Central Valley,” Haring said.

He further mentioned that for optimum weed control in the Valley, growers should plant in the early winter months in order to prevent annual winter weeds.

Haring worked with the UC Davis Cooperative Extension on three different sites across both the Central Valley and northern Sacramento Valley collecting data on growth rates for cover crops. He found that because the northern valley had more direct sunlight hit the ground, cover crops thrived, and as a result, weeds were minimized.

The research will not stop there, though, Haring ensured. “The study I’m working on is funded by the Almond Board, and it’s continuing for a second year and maybe a third, so we’re trying to repeat it and validate and then also sort and synthesize information because there are people working on weeds but also working on water, insect pests, pollinator health, nematodes, and call sorts of ecosystem services,” he concluded.

Tomato Spotted Wilt Virus Fights Back

New Strain Creates Challenges

By Mikenzi Meyers, Associate Editor

A new strain of the Tomato Spotted Wilt Virus has created a challenge among vegetable growers, making integrated pest management, or IPM, increasingly critical. Bob Gilbertson, plant pathologist at UC Davis, has insight and advice as to how farmers should tackle this new strain.

“The first thing is to know what’s out in your field. And there’s a good diagnostic test for curly top, spotted wilt, alfalfa mosaic, and other viruses,” Gilbertson said.

Bob Gilbertson

After the virus is confirmed, he encourages growers to explore their options of treatment. Prior to the new spotted wilt virus strain, growers could turn to the SW-5 resistance gene to cure their field. Unfortunately, Gilbertson explained, the new strain actually breaks that resistance, which is where IPM becomes even more important.

In the future, Gilbertson hopes to find additional resistance genes to break the new strain. Until that time comes, he wants to use good IPM to manage it.

Gilbertson further added, “Increased sanitation, removing overwintering hosts, weeds, and bridge crops like lettuce, and then timing the applications of thrips management better, to slow down the appearance of adult thrips that carry the virus,” are all examples of good IPM.
