California weather has been perfect for almond set

The warm, dry late winter weather in California has been good news for almond farmers who were concerned about a bee shortage during bloom, reported Capital Press.

"It looks good right now," said Rich Buchner, UC Cooperative Extension advisor in Tehama County. "The bees are out working like crazy. It's going to be warm and dry over the next 10 days, so it should be about perfect for almond set."

Almond growers are enjoying a vibrant blossom season even though California only had about 500,000 bee colonies available as of mid-February to pollinate this year's crop of 800,000 acres, according to Eric Mussen, UCCE specialist in the Department of Entomology at UC Davis. Typically, as many as 1.6 million are needed to provide two colonies per acre.

The favorable weather for bee activity comes with a catch, however. Precipitation totals are behind seasonal averages.

A 'multi-million dollar food fight' heats up, plus other recent news coverage

Currently, GMO labeling is not required in the United States. Some manufacturers label foods that do not contain GMOs.
Alison Van Eenennaam, UC Cooperative Extension specialist in the Department of Animal Science at UC Davis, commented on a KCRA news segment about Proposition 37, an initiative on California's November ballot that, if passed, would require special labeling on products that contain genetically modified ingredients.

The reporters called the proposition a "multi-million dollar food fight."

"All of the data that's come out from the American Medical Association and National Academy of Sciences have all agreed that the food products on the market today that are genetically engineered are safe," Van Eenennaam told the reporter

Polls show the 'Yes on Proposition 37' campaign  is "way ahead" of those who oppose the initiative, "but there's a long way to go until November," the reporter said.

Vision still pays dividends after 150 years
Sacramento Bee editorial

The Sacramento Bee editorial staff called the 1862 Congress of the United States one of the most productive in American history. One of the reason was it's passage of the Morrill Land-Grant College Act July 2, 1862. The act created the world's best system of public colleges and universities for people of modest means, the editorial said. Previously most Americans had no access to higher education. California took up the land-grant offer in 1864 and the University of California was born – at Berkeley – in 1868. Later, the University Farm would become UC Davis. The Citrus Experiment Station would become UC Riverside.

Building a better, tastier tomato
Lauren Sommer, QUEST Northern California, KQED

Lauren Sommer interviewed Ann Powell, associate researcher in the Department of Plant Sciences at UC Davis, about her finding that the gene that creates "green shoulders" in tomatoes influences the amount of sugar in the ripe fruit. Powell says now that they know about this gene, plant breeders could put it back in commercial varieties.

Bees need a hand, especially in drought
Debbie Arrington, Sacramento Bee

In honor of National Honeybee Day, the Sacramento Bee paid homage to the indispensable pollinator with information about the challenges it faces. Colony collapse disorder, drought and urbanization take their toll. There was some good news: "Bees got through the winter a little better," said Eric Mussen, UC Cooperative Extension specialist, apiculture. "This spring, we saw bigger, earlier and more swarms." However, nationwide, the hot dry summer has made it a tough year for honey production.

Questions about coyotes or bees? UC experts respond

The Napa Valley Register took a closer look at coyotes in western Napa County subdivisions, after neighbors started spotting the canines near their homes.

Reporter Peter Jensen talked to Robert Timm, director of the UC Hopland Research and Extension Center, which is located in Mendocino County. Timm said that researchers track reports of coyote attacks on humans, though no such attacks have ever been reported in Napa County.

For some Sacramento area trees, it's already spring

The Sacramento Bee reported that Bradford pear trees along Sacramento streets are blooming, and sidewalks were littered with flower petals after Monday's storm.

Reporter Debbie Arrington talked to Eric Mussen, UC Cooperative Extension apiculturist with the UC Davis Entomology department, about how the early warm weather might affect pollination and fruit formation.

"Honeybees don't really get confused," Mussen said. "They do act predictably. Anytime the temperature gets above 55 degrees, if there's food somewhere, they'll go get it."

Though petals may fall, Mussen explained that bees will be able to pollinate trees unless storm winds and rain knock entire flowers to the ground, leaving nothing to pollinate.

Re-washing bagged greens may do more harm than good

There's no need to re-wash pre-washed greens.
Re-washing bagged greens may be making salads dirtier, according to a bevy of food safety experts, reported Deborah Schoch in the Los Angeles Times.

Even the cleanest kitchens can teem with harmful pathogens - on cutting boards and in salad spinners, on knives that just sliced raw chicken, on damp, well-used cloth towels.

"In brief, consumers don't wash up very well and may contaminate produce due to dirty hands and dirty sink," emailed Christine M. Bruhn, director of the Center for Consumer Research at UC Davis. That's especially a problem with salad greens, since they never get cooked.

Schoch spoke to food experts from Kansas State University and the University of Maryland who also recommended pre-washed greens not be re-washed.

California apprenticeship building future producers
Amy Trinidad, Sheep Industry News

The American Sheep Industry Association is teaming up with the state sheep associations to expand the Let’s Grow initiative to include mentor programs for beginning sheep producers. 

“There is a real movement as far as people wanting to get back to the land. In some ways, it’s like the 1960s and 70s, only with a whole bunch of bigger challenges,” says Roger Ingram, University of California Cooperative Extension farm advisor.

Shepherds need to know how to run animals in a variety of environments, be able to identify common and uncommon pasture and range plants, know range nutrition, identify potential poisonous plants, be able to quickly asses the health of the flock and be able to take the appropriate steps in field conditions to fix problems, Ingram said.

Mild winter shifts the start of the growing season

The lack of rain has meant some Butte County almond growers have already irrigated twice, and some are starting a third run with the water. They would rather not water at all, and often don't need to this time of year, said Joe Connell, UC Cooperative Extension farm advisor.

It can cost about $40 to apply 12 inches of water to one acre, he said. Growers will think carefully before pumping if it looks like another storm is on the way. The most recent rain provided water to the first foot of soil, depending on the soil conditions. But almond growers will want the soil irrigated 3 to 4 feet down by bloom time.

Almond trees in the area will likely begin to bloom around Valentine's Day this year, about a week earlier than normal. 

Yuba-Sutter beekeepers abuzz on research
Jonathan Edwards, Orland Press Register

Losing bees to colony collapse disorder is not good for Yuba-Sutter. Beekeeping brought in about $3.9 million to area beekeepers in 2010, the last year for which data is available. On average, beekeepers have lost nearly one-third of their colonies each year since 2006.

That number likely skyrocketed last year as dwindling colonies drove higher prices. A shrinking supply of vibrant hives nearly doubled the price of a colony, from $33 to $58 between 2009 and 2010, according to the Sutter County Crop Report. The price nearly tripled again and is holding at about $150 a colony, said Eric Mussen, an apiculturist with UC Cooperative Extension at UC Davis.

"It just shot up," he added.

Pest threats 'overblown'

Glenn County farmers are restricted by law from planting cotton in the same field three years in a row if the level of verticillium wilt is detected in 3 percent or more of the crop.
It's been nearly 20 years since olive, walnut and pistachio farmers first declared war on cotton, but the Glenn County Board of Supervisors declared Tuesday that fear of verticillium dahliae levels might be a a bit overblown, said an article by Susan Meeker in the Colusa County Sun-Herald.

The board agreed to revisit the 2008 regulation that prevents cotton growers from planting in the same field three years in a row if the level of verticillium wilt is detected in 3 percent or more of the crop.

Doug Munier, farm advisor for University of California Cooperative Extension, said verticillium dahliae exists in native valley soils and is spread by movement.

"Verticillium was a minor problem with cotton was first planted in the mid-1990s and it is still a minor problem after 17 years of production," he said.

New bee threat more media hype than reality
Wayne Anderson, The Washington Times

Government officials, leading bee experts and average beekeepers around the country say the strange discovery of a deadly bee parasite fly that makes honeybees act "zombie-like" is not seen nationwide — but only in a recently published San Francisco State University study. And some even question the veracity of the discovery itself.

The parasite fly is a long-time resident of California and a known nemesis to other bugs besides honeybees, the article said.

“They’ve been known to infest or parasitize bumblebees for some time all over the country,” said Eric Mussen, California State bee specialist and professor at the University of California, Davis. “It’s not new. We’re aware of it. I don’t believe it’s a terribly important thing to honeybees as a whole.”
