The shut downs and self isolation sweeping across the country to curb the spread of coronavirus likely will not impact agricultural staple foods, but high-end wines and specialty ag products grown in California may suffer, reported Tim Hearden in Western Farm Press.
He said some California agricultural products see demand increase during tough economic times, such as less expensive wines.
“Central Valley grapes are nearly recession-proof,” he said. “When the stock market collapses or the dot-com busts, nobody's buying $200 bottles of wine anymore.”
Sumner said Midwestern corn and grains will hold their own, however California products like almonds, pistachios, walnuts, strawberries, raspberries and even some leafy greens may "slip off the plate."
Wine sales may also be hurt by California Gov. Gavin Newsom's decision to close winery tasting rooms, restaurants, bars and pubs. Wineries are allowed to remain open for pick-up and winery business and production operations.
Hearden noted in his article that many UC Cooperative Extension workshops and other ag-related public events were canceled, including Ag Day festivities at the state Capitol that were set for March 18.

Will machines replace the romance of the hand-cultivated wine grape vineyard? A “touchless” vineyard was among the latest research on labor shortages, weeds and pest management by UC Cooperative Extension scientists discussed at Grape Day at the UC Davis Oakville Station, located in the epicenter of California wine country, on June 6.
About 200 wine grape growers, vineyard consultants and other industry people attended to learn about the latest UC Cooperative Extension research. Vineyard managers from boutique wineries such as Fork in the Road to Pine Ridge Vineyards to the Fortune 500 wine company Constellation Brands gathered at the research station's experimental vineyard. Several vineyard equipment representatives brought their machines to the field to demonstrate their weeding, pruning and canopy management capabilities.
Addressing labor shortages
To help growers attract and retain farm workers, Monica Cooper, UC Cooperative Extension advisor for Napa County and her research assistant, Malcolm Hobbs, are conducting a survey of agricultural workers to determine the factors that affect job satisfaction. They found the number of female workers in Napa County has increased rapidly since 2013. “Women may be moving into the labor pool to fill vacancies caused by the decline in the number of male workers migrating to the U.S. for agricultural work,” Cooper said.
They plan to provide participating companies with custom recommendations for recruiting and retaining workers.
“We will also be generating a generic summary that will be widely shared with participants and non-participants at the close of the study. For now, we cannot make any general conclusions or recommendations because data collection is ongoing,” Cooper said. “We are aiming to distribute our final report this winter, so stay tuned.”
To help growers reduce their need for hand labor, UC Cooperative Extension viticulture specialist Kaan Kurtural designed a “touchless” demonstration vineyard that is mechanically managed. The mechanized vineyard is one of six trellis systems he is studying for water use, nitrogen use efficiency, yield and fruit quality of the wine grapes.
“We're always looking for ways to improve yield, quality and to reduce cost,” said Francisco Araujo, director of viticulture for Atlas Vineyard Management. “In light of the labor shortage we're facing right now, Kaan is exploring new production systems that include new trellises, mechanization, different types of mechanization from pruning to shoot thinning and trunk suckering. He's obtaining information about how these new trellis systems that he is investigating are going to play with yield and quality.”
The touchless vineyard experiment started out as a demonstration at first, but with grower interest, it turned into a full-blown research project.
“It started as way of saving labor costs, but when we started looking at the physiological aspects of how these plants grow, we saw the benefits from the quality point of view in addition to the labor savings,” said Kurtural, who is based in the Department of Viticulture and Enology at UC Davis.
A traditional vineyard in the Napa area is about a meter or 36 inches above the vineyard floor with vertical shoots held up with wires, which are moved by hand.
“We said, ‘Why don't we turn the system upside down?' Grow a tall trunk then put the bilateral cordon about 62 inches above the vineyard floor, that way we can push the rows a lot closer,” said Kurtural, who oversees the 40-acre Oakville experimental vineyard. The leaves grow down to generate the same leaf area as a traditional vineyard, but the leaves in the mechanized vineyard use water more efficiently so the no-touch vineyard requires less water compared to traditional vineyard systems.
“This is a dense system, this is 1.5 meters by 2 meters, roughly 1,340 plants per acre – we're getting by here on a third to quarter acre foot of water,” Kurtural said.
“It costs us roughly about a dollar in labor operation costs to manage each plant in a traditionally farmed vineyard of roughly about 1,300 plants per acre on the North Coast now,” Kurtural said. “The no-touch plants are costing us about 7 cents in labor operations costs.”
“The biggest expense is pruning, after that we go through what they call trunk suckering, which is also done mechanically here, and after that they will do shoot removal to open up the canopy. That's also done mechanically. After that, if there's need, they will do leaf removal, that's also done mechanically. And one last resort, if there's too much crop here, they will shake off excess berries with a harvester.”
The conventional system yields up to 5 to 6 tons per acre whereas the mechanized vineyard yields 7 to 8 tons per acre.
“These clusters set far fewer berries than a traditionally managed vineyard, but the berry size is also very small, which is what the winemakers like,” he said.
During harvest, grapes picked by machine are sorted on board the harvester so they go into the winery in uniform sizes, whereas hand-harvested grapes have to be sorted on a tray before they are put into the press tank.
“We made wines from these last year and compared to our traditionally farmed vineyards. Until we tell people what it is, they cannot distinguish the quality of the fruit or the wine.”
Weed and pest management
John Roncoroni, UCCE weed science farm advisor in Napa County, discussed options for weed control among young grape vines.
In the past, many vineyards were fumigated before planting for disease control, but it also provided weed control for young vines.
“With the loss of most fumigants for use in vineyards, hand-weeding was often used to accomplish this task,” Roncoroni said. “Increased costs and decreased labor force have made hand weeding impractical. Mechanical cultivation, at this point, is too imprecise – either leaving weeds close to young vines or causing damage by being too close.”
Covers on young vines allow the use of many post-emergence herbicides to control weeds, but Roncoroni cautioned that application of post-emergence herbicides on vines that aren't protected by mature bark may damage or even kill the vine.
“Herbicide use on vines less than 3 years old is a risky endeavor,” Roncoroni said. “Follow all label requirements, paying special attention to soil and irrigation recommendations.”
Lynn Wunderlich, UC Cooperative Extension advisor for the Central Sierra, and Franz Niederholzer, UC Cooperative Extension advisor for Colusa, Sutter and Yuba counties, demonstrated how to calibrate sprayers and to get uniform coverage when spraying fungicides.
In 2016, UC Davis researchers identified the three-cornered alfalfa hopper, Spissistilus festinus, as a vector of grapevine red blotch virus. Cindy Preto, a Ph.D candidate in the UC Davis Department of Entomology who is assisting UC scientists studying the three-cornered alfalfa hopper's biology and host plants, provided an update on their research.
Araujo, the viticulture consultant, said he and his colleagues value the university's research. “Napa Valley is a place where quality is paramount yet more and more we have labor shortage, we have inflation, production costs are going up,” he said. “Finding a way to get maximum quality along with yield levels that will pay for the increasing costs of production is the only way we'll be sustainable now and in the future.”
China imports quite a bit of wine, however, very little comes from the United States. At the same time, per capita consumption of wine in China remains very low. So why are California winemakers anxious about tariffs newly imposed by China on U.S. wine? Because China's wine consumption habits are expected to change, reported UC ANR experts in an article posted on The Conversation and NPR websites.
"China is the world's fastest-growing wine market and is expected to soon become the second largest (wine market), after the U.S.," wrote UC Davis wine economist Julian M. Alsten, director of UC ANR's Agricultural Issues Center Daniel Sumner, and post-doctoral scholar Olena Sambucci.
Economists who have studied these markets project further significant growth in China's demand for wine, including premium wine imports, the article said.
"This would make getting pushed out of China especially troubling at a time when global per capita wine consumption has been declining, especially in Europe," the authors wrote.
With the value of wine riding on a delicate balance of aroma and flavor, the impact of winegrapes' exposure to smoke from a wildfire could have significant economic consequences. Last fall's Northern California wildfires sent smoke wafting over an experimental vineyard in Napa Valley, giving scientists the opportunity to study the interplay of smoke and wine quality, reported Jeff Quackenbush in the North Bay Business Journal.
"The moment the smoke started, my phone started ringing off the hook," said Anita Olberholster, UC Cooperative Extension viticulture and enology specialist. “I quickly realized how thin the data is I need to base recommendations on.”
The fires near the UC Davis vineyard provided the perfect experimental platform. Olberholster and her research team sprang into action to start a research project on the fly. Remaining grapes on smoke-exposed vines were picked, loads of commercially grown grapes deemed too questionable for commercial wineries were accepted. Over the past five months, small batches of wine were made from the grapes.
“They all have different levels of smoky character,” Olberholster said. “Some on the nose are actually quite pleasant and not smoky, but the aftertaste is the problem. All of them, even if in small amounts, had that ‘old smoke,' ‘ashtray,' ‘new smoke' aftertaste. It all depends on how sensitive you're going to be at it.”
The scientists are now looking for a process that will remove the smoky compounds, as little as possible of anything else.
