Trees are facing stress from a variety of pressures in California, including climate change and exotic invasive pests, reported Jeanette Marantos in the Los Angeles Times.
“There are lots of invasive pests everywhere because of global warming and the movement of plant materials in general,” said Philippe Rolshausen, UC Cooperative Extension subtropical tree specialist at UC Riverside.
Yellowing leaves, a thinning canopy and branch die-back are symptoms that the tree is sick. UC Master...

Is your tree on death's door? Here's how to tell
(LA Times) Jeanette Marantos, Feb. 28
…Climate change, invasive species and even international trade are taking a serious toll on California trees. An estimated 150 million trees died during the drought that started in December 2011, according to Smithsonian Magazine, and the stressed trees that survived became more vulnerable to attack by a host of newcomer pests, said Philippe Rolshausen, subtropical tree specialist for the Cooperative Extension office at UC Riverside.
“There are lots of invasive pests...

Labor costs drive mechanized pruning technology
(Farm Press) Todd Fitchette, Feb. 14
… As labor costs in California escalate, growers are becoming more interested in cost-saving technology. The Sunpreme variety of raisin grapes, developed by the U.S. Department of Agriculture and released in about 2014, lends itself to more efficient pruning and harvesting.
The variety naturally dries on the vine, according to George Zhuang, a Cooperative Extension farm advisor who specializes in grapes in the Central Valley. Combined with an ability to mechanically box hedge the vines during the dormant season, Zhuang says this will be the first year the variety will experience fully mechanized management...
A 16-year-old high school student and sixth generation Santa Ynez Valley rancher Lily Masopust traveled to Denver for the Society for Range Management's annual High School Youth Forum Feb. 16-20, reported the Santa Ynez Valley News.

Faced with growing global food demand, one solution to increasing productivity is cutting air pollution, reported Ohio's Country Journal.
MIT Sloan School of Management visiting professor Konstantinos Metaxoglou and UC Davis ag economics professor Aaron Smith quantified crop yield increases attributed to recent reduction in the emissions of NOx from power plants in the U.S. They found that the average corn yield increased by 2.5% and soybeen yield by 1.6% from 2003 to 2011.
The increased yield led to an increase in the two crops' total annual surplus.
“While farmers are worse off and consumers are...
