As in past years, Dr. Brian Hogg at USDA’s Western Regional Research Center in Albany, California, is seeking research sites for bagrada bug research, and is interested to hear about bagrada bug infestations anywhere in California.  This is the time of year when bagrada bug populations usually start increasing in cole crop fields. High numbers may also be found on weeds, especially shortpod mustard and perennial pepperweed.  Any cole crop fields or weed patches that are infested with bagrada bug would work for our purposes. Time constraints prevent us from visiting sites more than four hours...

Joji Muramoto, a longtime research associate with University of California Santa Cruz, has been hired as the first University of California Cooperative Extension Specialist dedicated to organic agriculture. Muramoto will coordinate a statewide program focusing research on organic fruit and vegetable production. He will provide educational resources to producers on topics such as organic pest management and soil fertility. Cooperative Extension serves as a vital link between the University of California and the agricultural sector. Extension Specialists conduct research that addresses on-farm...

Wild Farm Alliance (WFA) and our partners are pleased to announce our fourth upcoming field day as part of our All Things Avian Series.  If you want more help with pest control, consider supporting beneficial birds. Learn who these birds are, what they need, and how to provide for them. The overwhelming majority of songbirds are beneficial in the spring and early summer when they feed insects to their nestlings. We’ll also discuss the few bird species that can be pests and how manage them.  We are bringing together farmers who use practices to support beneficial birds, avian researchers who...

The California Department of Pesticide Regulation (DPR) will hold a public hearing and commenting period regarding the designation of chlorpyrifos as a toxic air contaminant. Chlorpyrifos is a prohibited pesticide in organic production.  DPR will accept written comments on chlorpyrifos until 5:00 p.m. on November 9, 2018. Comments can be submitted electronically to dpr18002@cdpr.ca.gov or via fax to (916) 324-1491.  DPR will hold a public hearing on Thursday, November 8, 2018 at 2:00 p.m. at: California Environmental Protection Agency Headquarters BuildingSierra Hearing Room1001 I...

A blog entry written by Alejandro Del Pozo-Valdivia, entomologist with Cooperative Extension Monterey County, reports that bagrada bug adults were found on shortpod mustard plants north of Soledad and near King City. While no nymphs or eggs were found, their offspring may be moving into adjacent cole crops soon.    Newly planted or early-stage mustard family crops are most at risk from bagrada bug damage. Dr. Del Pozo-Valdivia encourages PCAs to check crops that fit this description in areas surrounding Soledad and King City.   No bagrada was found earlier this season in the San Ardo area,...

Organic Grower Summit December 12-13, 2018 at the Monterey Conference Center   The Organic Grower Summit (OGS) has announced Western Growers will again serve as the Ag Technology sponsor for this year’s event. As the Ag Technology sponsor, Western Growers will help coordinate the attendance of technology companies as exhibitors, and help facilitate elements of the technology area at the event.    To date, OGS has secured over 45 committed exhibitors and 35 sponsoring companies.   Among participating exhibitors are leaders in the fields of seed, soil amendments, food safety, and ag technology...

A recent blog post by Alejandro Del Pozo-Valdivia, UC Cooperative Extension entomologist based in Salinas, addresses reports he’s received about “red aphids” being found in organic romaine lettuce varieties that are resistant to the lettuce aphid.   Laboratory analysis showed that the “red aphids” were not lettuce aphids, but were actually either potato aphids or foxglove aphids.    Del Pozo-Valdivia’s blog shows pictures of different species of aphids and makes the point that body color is not the best trait to use to identify aphid species because they can change color during their lifespan...

Hedgerows, windbreaks, filter strips, grassed waterways, riparian areas, and beetle banks are increasingly being planted on farms and can have multiple functions: they can serve as habitat for beneficial insects, pollinators, and other wildlife; provide erosion protection and weed control; stabilize waterways; serve as windbreaks; reduce non-point source water pollution and groundwater pollution; increase surface water infiltration; buffer from pesticide drift, noise, odors, and dust; act as living fences and boundary lines; increase biodiversity; and provide an aesthetic resource.    Many...

California’s Department of Pesticide Regulation (DPR) released long-anticipated rules restricting pesticide applications close to public schools and daycare facilities.    The new rules require that pesticides using aircraft, airblast sprayer, sprinkler chemigation, or applied as a dust, powder, or fumigant between 6 a.m. and 6 p.m. Monday through Friday be located at least ¼ mile from schools.    At least 25-foot distance is required when application is made via ground-rig sprayer, soil injection equipment, or other types of applications including drip or flood chemigation.    There are no...

The laboratory of Dr. Brian Hogg of the U.S. Department of Agriculture’s Agricultural Research Service in Albany, California, is seeking sites for Bagrada bug research in California.    Any cole crop fields or weed patches that are currently infested with Bagrada bug would work for our purposes. We are investigating whether native predators or parasitic wasps attack Bagrada bug eggs as part of our efforts to develop a biological control program for Bagrada bug. We would put out frozen Bagrada bug eggs (dead, so there is no possibility of spreading the bug around) on index cards and leave them...

Spring is the time to anticipate pest problems that may emerge with the warmer weather of summer. It is a good time to remember what to look out for and to take some preventative steps to keep ahead of the pests. After the very wet winter in California, we might be about to experience an abundance of some of these pests, as well as invasive plants.   Because in California we grow so many crops over such a long season, there are always pests of concern.  Some pests are already under quarantine in certain regions, while other species are not quarantined but are worth preparing for. This blog...

The stakes are high in the fight to save California citrus from the threat of Asian citrus psyllid (ACP) and the disease it spreads, Huanglongbing (HLB) (also known as citrus greening). In Florida, more than 90 percent of commercial citrus trees are estimated to have HLB, and there has been a 70 percent decline in production, with an economic impact of $7.8 billion. California growers and government have invested heavily in trying to contain the spread of the pest and disease. Because of this, and somewhat because of the varied geography of California compared to Florida, the pest has not...

The fourth issue of Bagrada Bug News, a free newsletter dedicated to developing organic management strategies and biocontrol of the bagrada bug, is now available online. Bagrada bug, Bagrada hilaris, is an invasive stinkbug that first appeared in California in 2008. A prolific breeder with few organic control options, the pest has caused significant economic losses for organic growers, particularly in brassica crops such as broccoli, cauliflower, cabbage, and other mustard family members. CCOF joined with the California Department of Food and Agriculture to form a Bagrada Bug Working Group in...
