Strikingly beautiful with a striped yellow abdomen and ruby red and black polka dot wings, the spotted lanternfly's esthetic appeal belies its destructive nature.
“Spotted lantern fly is a major threat to apples, grapes, stone fruits, roses, landscape trees and the timber industry,” said Surendra Dara, UC Cooperative Extension entomology and biologicals advisor in San Luis Obispo, Ventura and Santa Barbara counties. “The agricultural industry and the public need to be looking out for this insect to prevent its migration and establishment in California.”
Native to China, spotted lanternflies were first introduced into the United States in 2014 when their presence was confirmed in Berks County, Penn. They have since established populations in New Jersey, Virginia, West Virginia, Delaware and Maryland. Spotted lanternflies are little more than a nuisance in their native range because they evolved along with controlling factors – such as predators and microbes – that achieved a natural balance. But when they arrive in new territory, the pest multiplies quickly and ravages plants.
While quarantine, management and research aim to control the pest where it has already taken hold, Dara is amplifying warnings of the pests' dire potential in agriculture-rich California and its ability to clandestinely hitchhike across the country. He held a webinar in May that attracted 130 participants from across California and the West, created a video, and posted articles in his eJournal and the Journal of Integrated Pest Management about current distribution, pest detection efforts and management strategies.
Inch-long adult spotted lanternflies have a nearly three-inch wingspan. Like giant aphids, the immature and mature stages of the pest suck sap out of plants and trees, depleting nutrients and reducing plant vigor, Dara said. While feeding, they emit waste sugars that cover plant leaves and invite fungi to grow black sooty mold, a coating that inhibits the plants' photosynthesis.
“SLFs can kill the host,” Dara said. “However, some survive because, when the plants start to die, the pest goes away to search for a healthier host, giving the plant the opportunity to recover.”
In the eastern U.S., residents say spotted lanternflies affect their quality of life and ability to enjoy the outdoors. The pest covers trees, swarms in the air and their honeydew can coat decks and playground equipment.
Spotted lanternfly movement is aided by females' ability to lay their nondescript egg masses on smooth surfaces of natural and human made objects, such as packages sent from distribution centers, long-haul trucks, railroad containers, recreational vehicles and automobiles.
“The egg masses are covered with a waxy gray-brown coating that looks like a splash of mud,” Dara said. “You may not notice it.”
Studies are underway to determine SLF egg-laying preferences.
Another concern for California in the face of a potential SLF infestation is the abundance of tree-of-heaven, itself an exotic pest from China and spotted lanternflies' favorite host. Tree-of-heaven – with roots, leaves and bark used in traditional Chinese medicine – was brought to California by Chinese migrant workers during the Gold Rush. Its tendency to grow rapidly and multiply quickly has resulted in its designation as a noxious weed.
Tree-of-heaven does offer a potential control strategy should SLF come to California. Landowners can remove 85% of tree-of-heaven specimens in a grove, including all the female plants. The remaining 15% of tree-of-heaven will be irresistible to spotted lanternfly. The insects will congregate in the trees, which may be treated with systemic insecticides to kill the entire population.
This is just one potential spotted lanternfly control strategy that could be part of an integrated pest management program. Other potential options Dara shared in his webinar and other communications are:
Traditional biocontrol. A parasitic wasp introduced into the United States in 1908 to control gypsy moths also appears to parasitize SLF eggs. Research may permit the introduction of other harmless natural SLF enemies from the pest's native range.
Microbial control. Naturally occurring fungi or those available as biopesticides can bring down SLF populations.
Mechanical control. Sticky bands placed on tree or vine trunks will trap the pest as it moves about.
Outreach. Communicate widely the concern about egg mass transport so people will inspect packages and vehicles and destroy egg masses.
The Fresno Bee has raised the alert for spotted lanternflies, a devastating pest from India, Vietnam and China that may be making inroads in California, the No. 1 agricultural area of the nation.
Reports of spotted lanternflies in California have been minimal to date. Agricultural inspectors found several dead lanternflies on cargo planes in Sacramento, Stockton and Ontario, and experts say a live spotted lanternfly may have been seen on the wall of a hotel in Davis in September. No others have been found alive, the article said.
Surendra Dara, UC Cooperative Extension advisor in San Luis Obispo County, said the lanternfly does pose a particular challenge for California, but the hope is that in the next few years, researchers will have the tools to wipe them out. The most likely method would be to use a “biological” method, such as introducing a natural enemy from Asian to manage the population.
“With a strong insect, just like the virus everybody is dealing with now, you need to understand the biology,” Dara said. “You have to understand every aspect of it. The more we know the better we can handle the situation.”

Expert: Speak up now about agriculture's carbon footprint
(Leader Telegram) Brooke Bechen, March 25
Dr. Frank Mitloehner, a professor and air quality extension specialist in the Department of Animal Science at the University of California-Davis, isn't afraid to speak up, particularly on Twitter where he writes under the handle @GHGGuru. He sees 2.5 million people visiting his Twitter account each month, which provides accurate information on air emissions and busts myths distributed by those looking to attack animal agriculture.
“Being in California is like being at Ground Zero,” he said. “There are urban centers of people who think they're food experts, but most of these people have never set foot on a farm and don't know anything about agriculture.
Wildfire Speaker Series Tonight: Fire Resistant Homes & Defensible Space
(YubaNet) March 25
…Dr. Kate Wilkin is the new Forest and Fire Adviser with UC Cooperative Extension in Butte, Nevada, Sutter, and Yuba Counties. She recently moved here from Berkeley, CA where she was postdoctoral researcher focused on wildfire emissions and fire-forest-water relations. Her PhD, also at UC Berkeley, focused on the efficacy of fuel treatments in Northern California shrublands to reduce fire hazards and on mixed conifer forest-fire-water and fire-biodiversity relations. Before moving to California, Kate grew up in rural Appalachia and then explored other fire-prone regions of the US as a natural resource manager and prescribed fire burner on public and nonprofit lands. Based on these experiences and more, she knows that we need to use solutions responsibly, both old and new, to solve our forest health crisis. Kate will be focusing on incorporating fire safe concepts into residential landscaping.

Landowners aim to fight fire with fire
(Benito Link) Blaire Strohn, March 19, 2019
The 2018 wildfire season in California was devastating, which left local landowners to consider how future blazes can be prevented. Their solution: more fire.
…UCCE livestock and natural resources advisor Devii Rao said the meeting also looked at Cal Fire funding and prescribed burn associations. She mentioned that last year former Gov. Jerry Brown signed two pieces of legislation related to prescribed burning:
Senate Bill 901 provides Cal Fire $1 billion for forest health, fuel load, and prescribed burns over five years, including $35 million a year for prescribed fire and other reduction projects.
Senate Bill 1260 requires Cal Fire to collaborate with public and private landowners on prescribed burns. They must also create a program for pre-certification for a “burn boss,” a private contractor that has experience in prescribed burning.
…In June, Rao will co-host a meeting with Lenya Quinn-Davidson and Jeff Stackhouse from UCCE Humboldt County. The meeting is expected to focus on how to develop a prescribed burn association, in addition to a small burn demonstration on a local private ranch.
A More Humane Livestock Industry, Brought to You By Crispr
(Wired) Gregory Barber, March 19
Hopes were running high for cow 401, and cow 401 serenely bore the weight of expectations. She entered the cattle chute obligingly, and as the vet searched her uterus, making full use of the plastic glove that covered his arm up to his shoulder, she uttered nary a moo. A week ago, Cow 401 and four other members of her experimental herd at UC Davis were in the early stages of pregnancy. But now, following a string of disappointing checkups, it was all down to her. Alison Van Eenennaam, the animal geneticist in charge of the proceedings, kept watch from off to one side, galoshes firmly planted in the damp manure, eyes fixed on a portable ultrasound monitor. After a few moments, the vet delivered his fifth and final diagnosis. “She's not pregnant,” he said. Van Eenennaam looked up. “Ah, shit,” she muttered.
Climate change is hurting migrating waterbirds across the West. It could get worse
(Sacramento Bee) Andrew Sheeler, March 18
…Some birds, like the black-necked stilt and the sandhill crane, which breed early in the season, have thrived in the warming climate, said Mohammad Safeeq, a hydrologist with the Sierra Nevada Research Institute and an adjunct professor at UC Merced.
But others suffer. That includes the killdeer, the Wilson's snipe, the black tern, and the western and Clark's grebe.
“We have looked at 14 species and among eight open-water and shoreline foraging species that have undergone significant population declines, five were negatively associated with temperature increases,” Safeeq said in an email interview.

US researchers moving abroad to avoid FDA's CRISPR-edited animal regulations
(Genetic Literacy Project) Cameron English, Alison Van Eenennaam, March 14
One day soon, farmers may be able to raise food animals immune to deadly diseases and spare them painful but necessary procedures like horn removal. These innovations, made possible by CRISPR and other gene-editing techniques, could cut the cost of food production, reduce antibiotic use in agriculture and dramatically improve animal welfare. But federal regulation may very well stifle these developments in the US.
In 2017, the Food and Drug Administration (FDA) proposed a plan to regulate gene-edited animals as veterinary drugs under the 1938 Food, Drug and Cosmetic Act, because their DNA is “intentionally altered.” The proposal has drawn harsh criticism from animal scientists, some of whom are packing up their labs and leaving the US to avoid the FDA's rules. Food animals, these experts say, should be regulated based on the risk they pose to human health, not the breeding method that produced them.
Corky Anderson's energy, innovation helped save California's pistachio industry
(Bakersfield Californian) Steven E. Mayer, March 13
"Corky was an important player in the early pistachio industry," said a Kern County farm adviser with the UC Cooperative Extension who specializes in citrus and pistachios.
"And he was a great cooperator," Kallsen said. "He allowed lots of test trials on his properties."
… In 1980, Anderson and Puryear's first patented rootstock changed the industry, said Kevin Blackwell, general manager of Pioneer Nursery, the wholesale business founded by the two entrepreneurs.
"In our heyday, we were selling a million trees a year," said Blackwell, who said he has known Anderson for 47 years.
No one does it alone, Kallsen noted. Anderson built and refined his patented rootstock based on earlier research by the University of California.
Farmers protect crops in rain's aftermath
(Ag Alert) Ching Lee, March 13
Franz Niederholzer, University of California Cooperative Extension farm advisor in Colusa, Sutter and Yuba counties, said though cold weather does reduce the risk of most fungal diseases, other problems such as bacterial blast and jacket rot—also a fungal disease—are more prevalent during cool weather.
Cooler weather, however, does help to extend the bloom, he said. That allows farmers more time to apply fungicide, which is recommended at the beginning of bloom and again at full bloom, he said.
Brent Holtz, UCCE farm advisor in San Joaquin County, said he hasn't seen too many problems with fungal diseases at this point, because of how cool it's been, but there have been more incidents of bacterial blast, which can infect trees under stress. In orchards with high nematode populations, the bacteria can enter wounds on the surface of the plants created by frost, he noted.
"It blights the blossoms, and if the blossom is dead, they don't produce fruit," Holtz said.

California's super bloom attracts swarms of migrating butterflies
(CNN) David Williams, March 13
This year's wildflower super bloom is not only filling California deserts with eye-popping displays of color -- it's also providing a feast for swarms of painted lady butterflies making their way north from Mexico.
"This is the biggest outbreak since 2005," said Art Shapiro, a professor at the University of California, Davis, who's been studying the migration of butterflies in the state since 1972.
…"I saw more butterflies in the last 10 minutes than I've seen my entire life," Jason Suppes wrote Tuesday on Twitter. Suppes is an education specialist at an agricultural research facility in Irvine.
Grape growers continue push to mechanize
(Western Farm Press) Lee Allen, March 13
…In Fresno, growers affiliated with the San Joaquin Valley Winegrowers Association met to discuss the latest UC research on incidents of disease and machine injury to trunks and rootstock.
… “Growers are having a hard time finding workers to maintain their vineyards and increasing labor costs are challenging grape-farming's economic sustainability,” says UC Cooperative Extension viticulture advisor George Zhuang. “We're studying the use of machines to reduce the number of people needed to perform tasks like pruning.
“Because canopy architecture and yield characteristics involving mechanically-pruned vines are much different from those that are hand-pruned, water and fertilizer requirements for the mechanically pruned vines can be quite different. Performance of different rootstocks in mechanical pruning systems is critical for both yield and fruit quality of grape production in the San Joaquin Valley.”
…Kaan Kurtural, UC Cooperative Extension viticulture specialist in the UC Davis Viticulture and Enology Department, whose research involves improving vineyard production efficiency through canopy and crop load management via mechanization, says the case for switching out hand labor with machines gets stronger with growers using such mechanization for pruning, suckering, and removing shoots and leaves.
“Mechanical pruning can produce more stable year-to-year fruit yields of better quality than traditional and more costly hand pruning spurs or canes.” His comments were based on a Kern County two-year research trial looking for ways for growers to reduce both cost and water use.

Western Innovator: Putting biologicals to work
(Capital Press) Padma Nagappan, March 11
Early in life, Surendra Dara decided that no matter which field he chose, he needed to make an impact on it. Always interested in science, he chose agriculture and specialized in entomology.
“It attracted me because it dealt with arthropods and there are a lot of physiological similarities to the human world,” Dara said. “It was also critical for growing food and feeding humans.”
Dara is now an entomopathologist with the University of California's Division of Agriculture and Natural Resources in San Luis Obispo, and has an established reputation for exploring innovative options to control pests using microbials as biological controls, and showing growers how they can also help with plant growth, drought resistance and fighting diseases.
Group linked to Ocasio-Cortez seeks ag input after Green New Deal backlash
(Politico) Helena Bottemiller Evich, March 11
After watching that drama unfold, Frank Mitloehner, a leading scientist on agricultural emissions at the University of California, Davis, was thrilled when two outreach staff affiliated with AOC's network reached out to set up a call to discuss the potential for climate mitigation efforts in agriculture. The call, held earlier this month, lasted more than an hour, Mitloehner said.
“I was very glad to inform of what I know, and they were very receptive to it,” Mitloehner said on Agri-Talk last week. During the segment, he urged agricultural producers to not dismiss the left-wing climate effort.
Sudden surge in an unusual crime in Fresno County: Goat theft
(LA Times) Hannah Fry, March 11, 2019
…Picquette's two sons have been raising goats for the last five years as a 4-H project. Losing their animals has been especially hard for the boys, Picquette said, adding that they had planned to use money won during competitions to pay for college.
“They feel very violated. They don't understand how somebody could just come and take something they worked so hard for,” she said. “The bond we have with the goats is incredible. I'm just heartbroken. I don't know if they're scared or hungry. … They've always been treated so well.”
California's ambitious plan to stop deadly wildfires may not be enough, experts say
(SF Chronicle) Kurtis Alexander, March 9
… “It's not fair to say that fuel treatments won't do any good,” said Max Moritz, a UC Cooperative Extension wildfire specialist at UC Santa Barbara. “It may provide some protection in some places. But most of us studying this agree that you can't just do this and (expect to) make much headway.”
The plan by the California Department of Forestry and Fire Protection, or Cal Fire, comes at the request of Gov. Gavin Newsom. On his second day in office, Newsom asked the agency to develop a proposal to address the increasingly destructive fire seasons that have rattled the state and are expected to worsen with climate change.
…In the meantime, many researchers say the most effective approach to fire protection is not in the forests, but in communities. They recommend making homes more resistant to fire with hardier construction materials, and clearing the vegetation around them.
“You have to address the home vulnerabilities themselves,” said Moritz at UC Santa Barbara. “If you don't, you're just not going to make a lot of progress on fire.”
After more than 140 years, a massive fig tree gracing the plaza where Los Angeles was founded collapses
(LA Times) Matthew Ormseth, March 9
… The four figs were planted at El Pueblo by agriculturalist and City Councilman Elijah Hook Workman, KCET reported in 2013. The Ficus macrophylla was brought from Australia to Southern California in the 1860s and 1870s, probably to provide shade and ornamentation, said Donald Hodel, a horticulture advisor for the University of California's Cooperative Extension.
Hodel described the Moreton Bay fig as a commanding breed of tree with an enveloping canopy that threw plenty of shade.
His reasons for admiring the Moreton Bay fig: “Their grandeur; their size — they have an imposing habit; their root structure is incredible; the spreading nature of their branches.”
Hodel said he last saw the El Pueblo figs about six years ago.
“I wasn't too impressed by their health or their size, considering they're 140-something years old,” he said.

Researchers highlight plan to eat healthy on a budget
(Consumer Affairs) Kristen Dalli, March 7
Following a healthy diet can come with a hefty price tag, but a team of researchers has outlined a way for consumers to stick to a healthy diet -- and also stick to their budgets.
According to the team, consumers -- and their families -- can have healthy meals if they focus on buying items in bulk and planning meals in advance.
“This study determines the likelihood that families living in low-income households could create meals that meet the USDA dietary guidelines presented in MyPlate nutrition education materials,” said researcher Karen M. Jetter, PhD. “In addition to food cost, the other factors considered were access to stores, time for meal preparation, and whether the menus included culturally appropriate foods.”

Sorry, Alexandria Ocasio-Cortez, but “farting cows” aren't the problem
(New Food Economy) Sam Bloch, March 7
…As it turns out, neither side was accurate. Republicans are likely to continue linking Green New Deal priorities to a supposed hamburger ban. But if you don't hear about cow farts anymore from AOC, it may not be because of GOP criticism. Frank Mitloehner, an animal scientist and air quality specialist at the University of California, Davis, insists cattle flatulence isn't the problem it's made out to be, and says he helped set the record straight.
Here's what seems to have happened. On February 4, shortly before Ocasio-Cortez announced the Green New Deal, she was speaking to school children in Queens, New York. When one asked how they could “combat” climate change, Ocasio-Cortez offered two practical options—stop using disposable razors, and skip meat and dairy for one meal.
Mitloehner tweeted at her.
“Dear @AOC: we all try to help the climate,” he wrote. “However, the two options you offered have low impacts compared to the 800lb gorilla, which is to reduce fossil fuel use. About ? of greenhouse gas emissions in the US stem from transport and energy prod&use. Meat/milk = 4 % of total GHG,” referring to findings in a recent EPA report.
… “I give her team a lot of credit for reaching out,” Mitloehner says. “If we really are serious about making a difference in carbon emissions, you cannot do this without agriculture involved.”
California supplies a quarter of the world's sunflower seeds
(Capital Press) Padma Nagappan, March 7
…Khaled Bali is a University of California Department of Agriculture and Natural Resources statewide water and irrigation specialist who has been working since 2016 on a four-year trial on sunflower varieties.
He was asked by the University of Georgia to help ascertain which varieties were drought resistant. He chose to conduct his trial in the low desert region of the Imperial Valley, since it gets little rain during the growing season between February when it's planted, and June when it's harvested. This would make it easier to control and measure the actual water applied to the crop varieties.
“We're looking at 285 varieties of sunflowers, to see which ones do well under stress,” Bali said. He has tested different plantings each growing season for the past three years, and will finish the trial this year.

Bees, blooms off to slow start
(Western Farm Press) Logan Hawkes, March 6
…This year, almond bloom started around a normal time, with some early varieties showing a few open flowers in the first week of February,” reported Franz Niederholzer, UCCE farm advisor for Colusa, Sutter, and Yuba Counties. “For most of the month bloom progressed very slowly,”
By the middle of February, he says, “bloom for Nonpareil was at least two weeks behind, and bee hours were limited until the last week of the month. Last year, between Feb 1-20, we accumulated 130 bee hours of good honey bee flying weather [55 F., no rain, and wind less than 10 mph]. For the same interval this year, we had around 10 hours and only six of those occurred with open flowers in the orchard.”
On the positive side of the slow start, Niederholzer says, the colder weather tends to suppress activity of key bloom diseases such as blossom brown rot and anthracnose. “However, cold weather at bloom was conducive to blossom blast (pseudomonas) bacteria, and some growers were considering adding materials to their normal bloom fungicides with bactericide activity.”
Wet winter aids groundwater replenishment
(Ag Alert) Christine Souza, March 6
… Helen Dahlke, a hydrology expert and professor with the University of California, Davis, Department of Land, Air and Water Resources, has been working with farmers, studying on-farm groundwater recharge locations and suitability for various crops.
"In many regions, we can definitely do more actively recharging our groundwater aquifers," said Dahlke, who currently has trials on alfalfa at the UC Kearney Agricultural Center. "It really depends on what region, how much surface water is available for recharge, what kind of sediment structure or hydrogeology we have underneath and whether it's suited for conveying large amounts quickly."
Despite abundant precipitation in recent weeks, she said the timing is not the best for studying impact of recharge on certain crops.
"We prefer on-farm recharge to happen in January and February, just because that is considered the dormancy season for most crops," Dahlke said. "With almond trees already blooming, often there is a greater risk of applying water on those crops."
She said recent precipitation has helped groundwater recharge overall, but there is "very little way of estimating how much it is helping."
Drip irrigation improves yields of Imperial sugar beets
(Ag Alert) Padma Nagappan, March 6
Halfway through a two-year irrigation trial to test furrow irrigation versus drip on sugar beet in California's Imperial Valley, Ali Montazar is looking for ways to boost yields with as little water consumption as possible in a region where furrow irrigation is the common practice.
Montazar, irrigation and water management advisor with the University of California department of agriculture and natural resources (UCANR) in Imperial County, is comparing and evaluating sugar beets for crop water use, sugar percentage, and yield, using both furrow and drip, since growers are now thinking of switching to subsurface drip.
Preliminary results from year one of the trial show that yield and crop water use are better with drip. Yield was 21 percent higher, and water use was a few points lower.
NFU says “No” to Green New Deal
(DTN) Jerry Hagstrom and Chris Clayton, March 6
Frank Mitloehner, an animal-science professor and air-quality Extension specialist at the University of California-Davis, reached out to Ocasio-Cortez's team about agriculture and the Green New Deal after seeing social media posts late last month about “farting cows” that drew a great deal of attention.
“I appreciate her interest in climate-change mitigation, but the 800-pound gorilla is the use of fossil fuels, and I told her that even the notion of cow flatulence makes this whole thing sound silly, and that's not what we need this discussion to be,” Mitloehner told DTN in an interview.
From Farting Cows to More Beans; Anti-Livestock Claims Fall Short

ABC7 News spoke exclusively to the 4-H instructor who taught two young girls the life-saving skills they needed to survive a weekend lost in the woods.
… Their mom, Misty Carrico, says she's not sure her daughters would have survived, if not for their 4-H program.
"The group leader Justin has taught them fire making skills and wilderness survival skills."
Justin Lehnert, the girls' 4-H leader, said, "I'm ecstatic that they did the job that they did. They're very strong girls and they stayed calm."
… Nine-year-old Caroline Gelormini has been a member of the San Bruno-South San Francisco 4-H Program for five years. Thanks to 4-H, she feels like she'd have a shot at surviving in the woods too.
Ocasio-Cortez Seeks Ag Data on Green New Deal
(Drovers) John Herath, March 4
When freshman congresswoman Alexandria Ocasio-Cortez released her Green New Deal plan, social media lit up with talk of her plan's mentions of “farting cows.” That drew the attention of agriculture's preeminent expert on air quality, Dr. Frank Mitloehner of the University of California at Davis, who tweeted back at the congresswoman.
“I don't know whether my tweet was the reason, but a few hours after I tweeted her, all mentioning of cow flatulence were taken off the web pages and of all social media outlets and was never to be heard again,” Mitloehner told Chip Flory on the AgriTalk Radio Show Monday.

Eructation Inflation: Greenhouse Gas Emissions of Livestock
(Science for the Rest of Us) March 1
Put your nerd hat on -- we cover a lot of ground in this fast-paced discussion with Dr. Frank Mitloehner of the University of California-Davis about the greenhouse gas emissions associated with the meat and dairy we consume. We consider how livestock emissions compare to other sectors of the US and global economies, the carbon footprint of vegetarian diets and what is the most effective way to reduce individual carbon emissions.
Keeping the Carbon Footprint of Livestock in Perspective
(AgNet West) Brian German, March 1
…“It is irresponsible and it's misguiding the public to believe that the true sources of pollution are downplayed, and the impacts of animal agriculture are grossly inflated,” said Dr. Frank Mitloehner, Professor and Air Quality Specialist in Cooperative Extension in the Department of Animal Science at the University of California, Davis.
UC Cooperative Extension plays an active and ongoing role in the effort to increase agricultural sustainability and minimize the industry's environmental impact, a role that was showcased at the third Ag Innovations Conference in March. Held in Santa Maria, the event was centered on the potential for using biological solutions for the challenges faced in agricultural production – such as pest control and nutrient management.
Many organic growers are already using these products successfully. Conference organizer Surendra Dara, UCCE advisor in Santa Barbara and San Luis Obispo counties, believes increasing the use of biologicals in conventional agriculture, which represents a much larger part of the industry, holds promise for reducing the use of chemical pesticides, cutting back nitrogen inputs and sequestering carbon in healthy farmland soil.
The market for biologicals in agriculture is growing. Organic farming is increasing in acreage because of consumer demand for food grown without synthetic inputs. In the conventional sector, farmers are wary of the new biological projects, probably because of past experiences with “snake oil” products that made glowing claims, but came up short. They are looking for scientific research that confirms their effectiveness.
“The most important thing we can do is remove the stigma about efficacy,” Dara said. “Conventional options are inexpensive and they are generally perceived to work better. It is a hard thing to shake.”
Finding funding for research in biologicals is another obstacle.
“Much more funding is available to research in conventional practices,” Dara said. “It's challenging for us. We must rely on industry support.”
Dara has conducted multiple studies demonstrating the potential of biologicals in crop production. At the March conference, he shared the results of experiments in tomato, strawberry and grape production in which he compared products containing seaweed extracts, silicon and beneficial bacteria and fungi.
“Many of the treatments worked well,” Dara said. “We saw some improved yield and good pest control.”
Research results are a key for mainstreaming biologicals in the ag industry, said Bill Schwoerer a speaker at the conference who represents Concentric Ag in San Luis Obispo, a company that produces biological optimizers for soil, seed and plant vigor. Concentric and other companies that are marketing biologicals said expectations need to be managed.
“It's not a silver bullet,” he said. “It's a tool to help you farm and produce a better crop.”
Concentric's product is a unique metabolite brew that contains seven bacteria and three fungi.
“It mimics a healthy soil microbiome,” Schwoerer said. “It's important to note, with these products, we see more improvements under stress conditions. That's the nature of the product.”
Ashraf El-kereamy, the former UCCE viticulture advisor in Kern County who was recently promoted to UCCE specialist at the UC Lindcove Research and Extension Center, presented results of his first year of research on seaweed extract applications on Flame seedless and Allison grape varieties in Kern County.
The products are derived from wild and cultivated seaweed from oceans around the world. Their potential as agricultural inputs stem from seaweed's rapid cell division and growth, a function that is controlled by natural plant hormones.
“Increasing color on red seedless grapes is important for marketing,” El-kereamy said. “Growers in the southern San Joaquin Valley are having an issue with coloring. Some growers had to dry their red grapes to raisins or sell to the juice companies because stores didn't accept the crop without good color.”
The research results are preliminary. And more potential impacts of the seaweed products still need to be studied – such as the impact on vine growth and stress tolerance, and the impact of the compounds on grapes grown in other areas or in different varieties.
But El-kereamy is encouraged by the early findings. The increased value of the redder grapes more than offsets the cost of the seaweed treatment, he said.
Other speakers representing firms that produce biological compounds for the ag industry also shared information at the Ag Innovations Conference:
- Paul Zorner, chief executive officer of Locus Agricultural Solutions, said the products made by the company target the soil microbiome and focus on high-value horticultural crops. The company has found that their probiotic supports more robust, consistent root growth by creating better nutrient status and a better microbial environment.
- Drew Jackson, vice president of Cool Planet, shared information about biochar, a product made by burning organic matter in an oxygen-deprived environment. He said biochar has unique properties that lend themselves healthy soil biology. “It's like luxury condos for microbes,” Zorner said.
- Antonin van der Lely of Biobest USA is working to move biocontrols that are used successfully in the greenhouse industry into outdoor agriculture.
- Katherine Walker, a technical service representative for BASF, discussed a biological fungicide from the company that can suppress root and foliar fungus. The product, called Serifel, can be used along with a chemical fungicide for added protection and resistance management.
- Melissa O'Neal of Marrone Bio Innovations presented information about two new Marrone products, Stargus and Ennoble. These products can also be used to alternate with conventional products to prevent resistance, she said. Stargus is a liquid fungicide that can inhibit botrytis in grapes and strawberries, sclerotinia in lettuce and downy mildew in lettuce. Ennoble is a granular bio fumigant that is incorporated into the soil, where it releases volatiles into plants' rootzones.
- Deb Shatley of Terramera said the company is formulating a product with cold-pressed neem oil that mixes with water in an application tank and stays in solution for days. Neem is a tree native of India and other South Asian countries that is a natural miticide, fungicide, insecticide and nematicide. The Terramera product, called Rango, provides more consistent neem spray coverage in the field.
