Bloomington nursery's citrus trees to be destroyed by California agriculture department
(ABC7 KABC) Rob McMillan, Jan. 17, 2018
Roxana Vallejo was 12 years old when her parents opened up Santa Ana Nursery in Bloomington.
On Wednesday, the California Department of Food and Agriculture will be at her business to destroy almost all of their citrus trees.
Vallejo said the combined value of the trees is almost $1 million.
"They're all fine, and look at all the new growth, it's pretty good," Vallejo said.
The reason they're being cut down is huanglongbing, or HLB, one of the world's worst citrus diseases. The insect that spreads HLB has taken a strong foothold in Southern California.
"It's estimated that the citrus industry may go commercially extinct unless they can get a handle on this problem," said Mark Hoddle, UC Cooperative Extension specialist at UC Riverside, more than one year ago.
Farm advisor tests strategies for controlling horseweed
(Ag Alert) Bob Johnson, Jan. 10, 2018
One morning last summer, University of California Cooperative Extension vineyard weed control advisor John Roncoroni displayed a horseweed plant that had grown to more than 10 feet tall in a Yolo County vineyard.
Horseweed, which is widely seen on the sides of the state's highways, is among the glyphosate-resistant weed pests that can develop healthy populations in even well managed vineyards.
"We're really having problems with weeds coming in the fall that are resistant to Roundup," Roncoroni said. "Willow herb is tolerant; it's never been completely controlled by glyphosate."
Western Innovator: Promoting sustainable ranching
(Western Farm Press) Tim Hearden, Jan. 9, 2018
Tracy Schohr has devoted much of her career to promoting sustainability in ranching.
While at the California Cattlemen's Association, she put on an annual “rangeland summit” that brought ranchers together with environmental experts and climate change policymakers.
She also worked on a program to limit ranchers' risk of facing Endangered Species Act violations if they created habitat on their land.
After going back to school to earn her master's degree at the University of California-Davis, Schohr has become a UC Cooperative Extension livestock and natural resources adviser based in Plumas, Sierra and Butte counties.

“Weeds are probably one of the year-in, year-out problems that growers face,” said Brad Hanson, UC Cooperative Extension, who discussed herbicide resistance with California Ag Today.
Building blocks for tending flocks
Workshop series to teach sheep handling and herding skills
(Auburn Journal) Julie Miller, Jan. 7, 2018
Counting sheep is no longer for the tired and sleepy.
Shepherding has become a booming industry in Placer County. At last count, there are 9,000 head of sheep registered with the county, said Dan Macon, livestock and natural resources advisor for University of California, for Placer and Nevada counties. And there may be more sheep that have not been registered, perhaps because they are in a smaller flock of 10 to 15, he said.
Sheep have proven to be versatile. Not only raised for the meat and milk, but also wool fibers, plus, they can help reduce fire danger by eating away tall grasses and shrubs.
After a recent outbreak of E.coli, is it safe to eat romaine lettuce? Experts differ
(Fresno Bee) Robert Rodriguez, Jan. 5, 2018
If you are staying away from romaine lettuce because of an outbreak of E.coli, it's understandable. But at least one food safety expert says it may not be necessary.
…But University of California food safety expert Trevor Suslow said it's unlikely the lettuce you buy at the grocery store these days is going to do you any harm. That's because the illnesses happened from Nov. 15 through Dec. 8. Lettuce sold during that period wouldn't be around anymore.
“It's not going to last that long, it's gone,” Suslow said.
2017's natural disasters cost American agriculture over $5 billion
(New Food Economy) Sam Bloch, Jan. 4, 2018
Over a period of 10 months in 2017, America experienced 16 separate, billion-dollar weather and climate-related disasters. Those weather events carved paths of destruction straight through some of the most fertile and productive regions of the country, wreaking havoc on beef cattle ranches in Texas, soaking cotton and rice farms in Louisiana, orange groves in Florida, and burning up vineyards in California. And that was all before Southern California's still-active Thomas fire, which began on December 4, and then closed in on the country's primary avocado farms. It's now the state's largest-ever, in terms of total acreage.
Acres of cherimoya trees in Santa Barbara County destroyed by the Thomas fire: 100
Total dollar value of Santa Barbara cherimoya fruit damaged by fire: $5,000,000
Acres of avocado fields in Santa Barbara and Ventura Counties threatened by wildfire: 5,260
Estimated pounds of Hass avocados in Ventura County lost to wildfire: 8,060,000
Total dollar value of that lost harvest: $10,175,750
Approximate percentage of American avocado crop threatened by wildfire: 8
Expected effect of wildfire on avocado prices in America, due to reliance on imports: 0
Winegrape acreage in Napa and Sonoma Counties: 104,847
As a percentage of total California winegrape acreage: 22
Estimated dollar value of unharvested Cabernet grapes in those counties, before the wildfires: $175,000,000
Estimated dollar value of those grapes, now tainted by smoke: $29,000,000
Bottles of 2016 Napa Cabernet you can buy for the price of two 2017 vintages, due to winegrape scarcity: 3

There Is No “No-Fire” Option in California
(Bay Nature) Zach St. George, Jan. 2, 2018
As the use of prescribed fire by Cal Fire declined in recent decades, its use also declined with private landholders, says Lenya Quinn-Davidson, director of the Northern California Prescribed Fire Council, who leads prescribed burning workshops across the state. Scott Stephens, the UC Berkeley professor, concurs. Decades of suppression left the western U.S. with relatively few people trained to carry out the work: “We just don't have that experience to pass on.” But it's important not to let the current enthusiasm pass, he says—as climate change continues to push conditions toward extremes, as wildfires consume more and more of fire agency budgets, and as the wildland-urban interface expands, it will only become more difficult to bring fire back.
(Lodi Wine blog) Randy Caparoso, Jan. 1, 2018
This coming February 6, 2018, Lodi winegrowers will get together for their 66th Annual LODI GRAPE DAY. They will also mark the occasion with a celebration of the retirement of Paul Verdegaal, who has been working full-time as San Joaquin County's viticulture, bush berry and almond Farm Advisor under the auspices of UCCE (University of California Cooperative Extension) since 1986.
The California rainy season is off to a good start, raising hopes that the ongoing drought will be snapped, reported Aaron Davis in the East Bay Times.
"We've seen a sigh of relief from a lot of growers that are right at about half of their total seasonal average and we are halfway through the season," said Paul Verdegaal, UC Cooperative Extension viticulture advisor in San Joaquin County.
The rain is helping flush salts away from the grapevines' rootzones and refill the aquifer, which has been depleted in some areas due to the years-long drought.
The National Weather Service's Seasonal Drought Outlook shows areas of Northern California already free from drought, some areas where the drought designation remains, but is improved, and areas where drought designation removal is "likely."
Half of the state's annual rainfall comes in December, January and February. "This is only mid-December .... So we still have a ways to go in our wet season and Northern California is well above average," said Jeanine Jones, deputy drought manager with the California State Department of Water Resources.
The concept of RDI has been the subject of UC research for decades. Traditionally in irrigated agriculture, farmers give crops all the water they can drink. RDI relies on research that shows exactly when farmers can withhold water from crops and when to irrigate for maximum water efficiency.
Paul Verdegaal, UC Cooperative Extension advisor in San Joaquin County, said water deficits at the right time in plant and fruit development can improve berry quality, especially in red wine varieties, by intensifying color and flavor. Slight deficits also limit excessive growth of shoots and leaves that can affect diseases, such as bunch rot.
"So far the crop doesn't seem all that much lighter than average," Vergegaal said. "Most growers who have been using RDI for the past several years have seen very good quality of fruit and little to no difference in yields from years past.”
The story said Paul Verdegaal, UC Cooperative Extension advisor in San Joaquin County, has been tracking local crop and weather data for 30 years and to date has seen only normal year-to-year variability.
"There's no particular trend in early bud break (in vineyards); there's no particular change in earlier harvest," Verdegaal said. "I haven't seen any hint of a trend, let alone a consistent pattern of increase or decrease."
Bud break, the point when grapevines begin to leaf out, falls each spring around March 15.
"This year, it was the 18th; last year, it was the 17th," Verdegaal said. "There's no change."
Saving county's 4-H program is essential
Linda Greco, Santa Maria Times
The UC Cooperative Extension Santa Barbara County is once again on the chopping block, according to a commentary by Linda Greco in the Santa Maria Times.
"I implore our community and county supervisors to consider the consequences and repercussions of such an action. Without the county’s commitment, the program will be lost and no longer exist," Greco wrote.
Greco's article noted that the Santa Barbara County Board of Supervisors planned to cut UCCE from the county budget in 2010, but after "community outcry," provided one-time funding with significant cuts.
"While 4-H celebrates 100 years in California in 2014, will 4-H continue to exist in our county for future generations? Assist me and ask the Board of Supervisors not to cut the UCCE funding, and to replace it as a permanently funded item to ensure the sustainability of the 4-H program into the future," she wrote.
"We'll take any and all cold that we can at this time of year to fulfill the chilling requirements of the trees," Grant said.
Paul Verdegaal, UCCE advisor in San Joaquin County, a viticulture expert, agreed.
"The good side of the story is we're catching up on the chilling hours, which will produce a good strong bud bread and bloom for all the perennial crops," Verdegaal said. "(Subfreezing temperatures, however,) may be hurting some younger trees and vines, but generally, things are in dormancy, so it's not too much of a problem."
"For us out here, the cold nights are good," Norton said. "We fare quite well because we don't grow subtropical crops like citrus and avocados."
Scott Stoddard, UCCE advisor in Merced County, said crop storage facilities need to pay attention to temperature control when the weather gets very cold.
"We have a lot of sweet potatoes in storage," he said. "They guys need to make sure their storage rooms are working properly and don't get too cold."
"Actually, this is beautiful," Duncan said. "Tree crops need cold in order to break their rest."
