Retail nursery and garden center employees play an important role in communicating pest management information to gardeners and the public. The UC Statewide IPM Program (UC IPM) strives to help retailers stay current on emerging pest-related topics facing California that help consumers effectively manage pests.
As part of this effort, UC IPM partnered with several UC Cooperative Extension Advisors and Specialists to offer three regional train-the trainer workshops in 2016 and early 2017. A total of 188 participants from 41 retail.../span>
What are those white, frothy masses you see on your rosemary, salvia, lavender, or other plants? Spittlebugs. The masses of froth can be found on plant foliage, cones and stems.
Inside the foamy mass you will find immature spittlebugs feeding on plant tissue. Adult spittlebugs (also called froghoppers) can also be found on the plant, and are ¼ of an inch long, and green or brown.
Although not aesthetically pleasing, occasional masses of spittlebug generally do not harm established woody plants.
The best way to deal with spittlebugs is to wash them off with water, ignore them, or handpick the bugs. Pesticides are not usually effective or needed and can cause harm to pollinators that often visit these...
The following press release was distributed on April 13, 2017 by the Citrus Pest & Disease Prevention Program.
Huanglongbing was confirmed in a single citrus tree in the City of La Habra in Orange County on April 11. This new find will result in a new HLB quarantine area, which will link the existing quarantines into a contiguous zone spanning portions of Los Angeles and Orange counties.
Additionally, two samples of Asian citrus psyllids in Anaheim tested positive for carrying the bacteria that causes HLB. These lab results were confirmed last week, and the California Department of Food and Agriculture is treating host plants in the surrounding 800-meter area. No...

In the garden, catchweed bedstraw competes with landscape plants for nutrients, water and light. Once mature, it can reach 6 feet long and be problematic when it smothers desirable plants. It can also make it difficult for gardeners to harvest produce.
Catchweed bedstraw is a winter or summer annual in California. The best control is to physically remove it as soon as it appears so it does not spread. For tips on how to manage this weed in your landscape, please visit the

A mountain lion entered an Orange County corral last week where nine pygmy goats belonging to members of the Trabuco Trailblazers 4-H Club were housed. Only one goat survived the encounter.
UC Cooperative Extension human-wildlife interactions advisor Niamh Quinn said she was heartbroken, but not surprised.
“We know that this is happening all over California,” Quinn said. “Sixty to 85 percent of depredation permits are issued to hobby farmers and ranchers who seek to kill wild animals that threaten their livestock.”
The loss of the goats is a sad reminder for Californians to be aware of wildlife predators in their areas and make sure that livestock enclosures are secure against...
