To prevent Asian citrus psyllid populations from developing in Kern County this fall, the San Joaquin Valley ACP-HLB Task Force recommends growers with citrus blocks east and south of Bakersfield make a soil-applied imidacloprid treatment or a foliar-applied Actara treatment before mid-September.
Over the past several years, psyllid detections in Kern County have usually occurred in the fall – starting in September and peaking in October. The San Joaquin Valley ACP-HLB Task Force has been tracking and analyzing psyllid detections to date in Kern County and believes a soil-applied imidacloprid treatment or a foliar-applied Actara treatment will help suppress this historical increase in the fall psyllid population and minimize the risk of Huanglongbing (HLB) transmission.
In order to protect our citrus from HLB, it is extremely important to keep psyllid populations as low as possible. Last year’s coordinated treatment significantly helped mitigate and suppress this historical increase in the fall psyllid population and inhibit possible transmission of HLB. This is especially important in light of the significant level of HLB-positive citrus trees in Los Angeles, Orange and Riverside counties.
The San Joaquin Valley ACP-HLB Task Force recommends growers with citrus blocks east and south of Bakersfield should:
- Treat all of their citrus blocks, including non-bearing trees, located east and south of Bakersfield with imidacloprid (Admire Pro, generic imidacloprid 2F or 4F, etc.) or a foliar-applied Actara treatment.
- Make the application sometime between mid-August and mid-September.
- Read and follow all label instructions. Read the University of California’s recommendations.
- Submit your Pesticide Use Report for this application electronically if possible. If you cannot send electronically, send a copy of the original PUR directly to Kern County grower liaison Judy Zaninovich at firstname.lastname@example.org.
