Message from the ACP/HLB San Joaquin Valley Task Force:

‘Now is the time to act against increased Asian citrus psyllid’

The ACP/HLB San Joaquin Valley Task Force has sent out a message to the San Joaquin Valley citrus growers.

"To all Citrus Growers in the San Joaquin Valley,

The ACP/HLB San Joaquin Valley Task Force called a meeting on Oct. 8 due to the increased number of Asian citrus psyllid (ACP) trap finds in the southern part of Kern County.  In the last month (September and into October), there have been a total of 35 ACP trap finds in the areas of the south part of Bakersfield, Arvin, Lamont, Mettler and Maricopa. There were 15 residential and 20 commercial citrus sticky trap finds. While there have been finds in some of these areas in the past, the amount of detections in this last 30-day period is alarming. The Asian citrus psyllid, as a reminder, transmits Huanglongbing (HLB); the best way to prevent HLB is to control ACP, which the valley has been successfully doing. 2020 has been a suspiciously quiet year for ACP finds but now, it is time to act.

We are now in the late part of the season where most spray programs have already been executed.  A coordinated spray is not recommended at this time.  Kern County growers are encouraged to use an ACP effective material if they have not done so in the last six weeks. It is prudent for all growers to use ACP effective materials when treating other pests. Regarding the residential finds, CDFA is at various stages of treating them.  Prior to these finds, CDFA had released Tamarixia radiata in certain residential areas of Kern County. Future Tamarixia releases are scheduled.

The task force wants to convey the seriousness of what is being seen and what it means to our industry. Unfortunately, the suspicion is that these finds in commercial citrus groves are spilling over from residential properties. It is up to the citrus industry to deal with this threat. San Joaquin Valley citrus growers have done a good job using ACP effective materials when treating. The cooperation shown by growers during coordinated treatments reflects their commitment to keeping ACP suppressed. Nevertheless, task force members wished to highlight what should be done to help control the Asian citrus psyllid here in the valley."
