Citrus Grower Workshop REMINDER (April 26) Dr. Beth Grafton-Cardwell will present findings from her continuing survey of ACP populations across Ventura County, including data on the effects of pesticide treatments on ACP abundance. Other speakers will present updates on the statewide Citrus Pest and Disease Prevention Program, the status of Huanglongbing disease in California, grower participation in the local ACP suppression effort, and updates to the Fall 2018 ACP area-wide treatment schedule. The workshop will be from 9:30 to 11:30 a.m. on Thursday, April 26, at the Agriculture Museum, 929 Railroad Ave., Santa Paula. Attendance is free, but advance registration is required. Please register online at: https://vctaskforce-workshop.eventbrite.com.
HLB Confirmations The number of trees confirmed as being infected by HLB has reached 552 (321 in Orange County, 228 in Los Angeles County and 3 in Riverside County). All were in residential settings, not commercial groves. The HLB quarantine boundaries and the latest tally of HLB confirmations, updated weekly, is available online at https://citrusinsider.org/maps/. As confirmations increase and spread closer to commercial citrus, it is a good time to consider removing citrus trees not worth the resources required to protect them from ACP and HLB.
ACP Areawide Treatments Thank you to those submitting timely ACP treatment pesticide use reports (PURs) and providing the grower liaisons with updates such as contact information and farm manager/applicator/PCA changes. This helps ensure ACP treatments are immediately recognized, and allows more effective communication with growers.
The Spring uncoordinated ACP treatment window begins now through July 15. Although these treatments are not coordinated, psyllid populations must be kept low to reduce the risk of HLB. Scout/monitor and treat if you see ACP, and use an ACP-effective material during spring/summer management. Click here for University of California recommendations for ACP monitoring.
Upcoming Meetings The Citrus Pest and Disease Prevention Committee will meet May 9 in Ventura. Attendance is free. Here is a link to the CDFA site with agenda, venue, and webinar information: https://www.cdfa.ca.gov/citruscommittee/.
