Gardens Have Pulled America Out of Some of Its Darkest Times. We Need Another Revival.
(Mother Jones) Tom Philpott, May 29
The first great national gardening mobilization came two decades later, scholar Rose Hayden-Smith writes in her 2014 book Sowing the Seeds of Victory: American Gardening Programs of World War 1. Building on a Progressive Era push to install gardens in public school yards as an educational tool, President Woodrow Wilson tapped the Bureau of Education, with funding from the War Department, to launch the US School Garden Army shortly after sending troops to intervene in the European conflict. “A Garden for Every Child,” its slogan promised. “Every Child in a Garden.”
The School Garden Army was just one of several national programs that “encouraged Americans to express their patriotism by producing and conserving food,” Hayden-Smith adds. Wilson also promoted a civic gardening boom through the Committee on Public Information, which hired writers, artists, scholars, and advertising professionals to create marketing campaigns to promote school, home, and community gardening.

Women Taking the Reins at Marin's Family Farms
(Marin Magazine) Christina Mueller, May 27
…The two sisters, who grew up on the family ranch but no longer live there (Melissa lives in Novato, Jessica lives in Bend, Oregon), were looking to re-establish their connection to the family's West Marin land. After attending a University of California Cooperative Extension (UCCE) and MALT agricultural summit 15 years ago that focused on helping the next generation of Marin ranchers figure out how to sustain small family farms, the sisters started researching, digging into their family history to learn what Angelo and subsequent generations of Poncias produced. Cattle, dairy and potatoes kept appearing at the top of the list. With the help of the Tomales Regional History Center, they found an old Petaluma Argus Courier newspaper advertisement where their grandfather posted about the potato varietals he was working with. One of those varietals was known as the Bodega Red.
San Joaquin County cherries withstand ‘spotty' rain losses
(Ag Alert) Kevin Hecteman, May 27
… Rain gauges around the area showed 0.19 to 0.52 inch fell during this year's May storms, according to Mohamed Nouri, a University of California Cooperative Extension orchard advisor in San Joaquin County, with cherries in the Escalon area being among the most affected
… Temperature plays an important role in the rate of cherry fruit cracking, Nouri said; more water is taken up when the temperature is warm following rain, causing the cherry to expand and split.

Leafy Green Growers Will Survive COVID-19
(Growing Produce) Carol Miller & Frank Giles, May 20, 2020
…“The lag in adjusting to the situation is mostly a two-month window for a crop like lettuce,” says Richard Smith. Smith is a University of California Vegetable Crop and Weed Science Farm Advisor at the Cooperative Extension in Monterey, Santa Cruz, and San Benito counties.
…“Companies varied in their level of exposure to this market that just collapsed,” Smith says. “Some were more exposed than others. Given other issues with the food distribution system, in general, some growers think that they may be 30% overplanted.”

Here's how to stay safe while buying groceries amid the coronavirus pandemic
(Brooklyn Reader) Erin DiCaprio, May 19
Wear a mask, but skip the gloves. Don't sanitize the apples. And if you are older than 65, it's probably best to still order your groceries online.
As a food virologist, I hear a lot of questions from people about the coronavirus risks in grocery stores and how to stay safe while shopping for food amid the pandemic. Here are answers to some of the common questions.

These 5 foods show how coronavirus has disrupted supply chains
(Nat Geo) Sarah Gibbens, May 19
… “What we have is a low-cost and efficient system that allows for huge variety and attention to individual tastes,” says Daniel Sumner, an economist at the University of California, Davis.
“A dairy farm has milk coming out of the cow into a tank. That milk must be pasteurized and packaged, meeting lots of food safety standards,” says Sumner.
Individual farms generally can't afford the equipment necessary to process milk on site without raising prices significantly. “Nowhere is a dairy farm suited to send milk directly to a store,” Sumner says.
UC Cooperative Extension in Humboldt County has invited local cannabis farmers to meetings this week to discuss ways to reduce the industry's environmental impacts, reported Will Houston in the Eureka Times-Standard.
UC advisors and specialists will discuss future research aimed at reducing the impacts of pesticide and fertilizer use on cannabis grows.
At this week's meetings, Giraud said, "Mostly we just want to listen to folks who come to the meetings ideas and concerns. They're on the ground. We just want to know what could be planned with us."
The meetings will be from 6 to 8 p.m. Oct. 3 at Adriana's Restaurant, 850 Crescent Way, Arcata; and 12 to 2 p.m. Oct. 4 at Women's Civic Club, 477 Maple Lane, Garberville.
There will be brief presentations followed by group discussions. The UC participants include Van Butsic, UC Cooperative Extension land use science specialist at UC Berkeley; Kent Daane, UCCE biological control specialist at UC Berkeley; Houston Wilson, post-doctoral researcher at UC Berkeley; and Giraud.
“They lost too much income,” said Glenn McGourty, a UC Agriculture and Natural Resources Cooperative Extension advisor in Lake and Mendocino counties. “They decided they were not going to risk their crop until there is a workable biological control solution to this new pest.”
Meanwhile, other organic grape producers are hanging on to their organic certification and counting on UC ANR researchers to come through with a biological control option soon.
“Organic farmers are spending a couple hundred dollars per acre for organic pesticides,” McGourty said. “They don't want to use them. It takes out beneficial insects and it doesn't even control Virginia creeper leafhopper very well.”
Three leafhopper species are pests of California grapes. Western grape leafhopper is a native insect that's present throughout California north of the Tehachapi Mountains. Several natural enemies keep the pest in check most years. Variegated leafhopper migrated north from the Imperial Valley to Central California in the 1980s, and is established in Napa Valley and other valleys of Napa County. Virginia creeper leafhopper, a native of the northern Midwest, made its way to Northern California in the early 1980s. It migrated southward to the northern Sacramento Valley and Sierra foothills, and most recently was detected in Lake and Mendocino counties, where the population boomed.
“The farmers were devastated, especially financially,” McGourty said. “Conventional growers had to begin spraying pesticides. Some organic vineyards were completely defoliated.”
The leafhoppers' key natural enemies are fairyflies (Genus: Anagrus), among the tiniest flying insects in the world. Certain species of fairyflies attack certain species of leafhoppers. What has scientists perplexed at the moment is the fact that Virginia creeper leafhoppers' natural enemies are present in Mendocino and Lake counties, but they are failing to do their job.
Generally, fairyflies lay their eggs in leafhopper eggs, killing them. The fairyflies known to attack Virginia creeper leafhopper are successfully parasitizing the pest's eggs in Yolo County. However, the very same species of fairyfly is not recognizing Virginia creeper leafhopper eggs as a host in Mendocino and Lake counties.
Kent Daane, UC ANR Cooperative Extension specialist based at the UC Kearney Agricultural Research and Extension Center in Parlier. “Although these Anagrus parasitoids can attack both Western grape leafhopper and Virginia creeper leafhopper, the Anagrus population in Mendocino County has been reproducing on Western grape leafhopper for so long, they seem to have lost their preference for Virginia creeper.”
The scientists believe that, in time, fairyflies in Lake and Mendocino counties will begin to parasitize Virginia creeper leafhopper eggs on their own. But, because of the severity of the situation to organic winegrape growers, they've hatched a plan to help out the natural enemies. This summer, they will be rounding up fairyflies in the Davis area – where they know how to attack Virginia creeper – and bring them to Lake and Mendocino county vineyards.
Beginning in April, Wilson will allow Mendocino area Virginia creeper leafhoppers to lay eggs on potted grapevines. The vines will be transported to Davis, where local fairyflies can parasitize the eggs. The plants will go back to the laboratory in Berkeley so scientists can rear populations of the parasitoids and later release them in Mendocino and Lake county vineyards.
“I just planted the grapevines this month,” Wilson said. “When leafhoppers become active in the summer, we'll start monthly releases. We hope our efforts will take some of the pressure off winegrape farmers soon.”
In addition to the work releasing natural enemies of Virginia creeper leafhopper, UC Agriculture and Natural Resources scientists are implementing an area-wide integrated pest management program in Mendocino and Lake counties. The program – a combination of biological, cultural and chemical controls for this pest – employs:
- Improved monitoring and mapping of Virginia creeper populations
- Cultural practices to reduce egg deposition in vineyards
- Earlier and coordinated pesticide applications (if a spray is necessary)
The Virginia creeper leafhopper pest control program is funded in part by the American Vineyard Foundation.
An initiative to manage endemic and invasive pests and diseases is part of UC Agriculture and Natural Resources Strategic Vision 2025.
