To protect commercial citrus from Huanglongbing (HLB), it is critical to keep Asian citrus psyllid (ACP) populations in groves as low as possible. While there has been a significant amount of monitoring and preventative ACP treatment in Kern County, the San Joaquin Valley ACP/HLB Area-Wide Task Force recommends that all commercial citrus orchards east and south of Bakersfield be treated with an ACP-effective insecticide sometime within the next two to three weeks.
Kern County Post Petal Fall Treatment – Treatment Guidelines for Commercial Citrus
- Treat ALL citrus blocks located east and south of Bakersfield, including non-bearing trees and blocks not normally treated at this time.
- Use an ACP-effective insecticide sometime within the three weeks following April 15, 2018. For a list of ACP-effective insecticides, please reference this list provided from the University of California.
- Treat the borders of blocks first as ACP tend to initially populate these areas. As a result, ACP will be driven toward the center of the block, where there should also be treatment, instead of away from the block and into surrounding areas.
- Submit your Pesticide Use Report for this application as soon as possible.
