To maximize the impact of Asian citrus psyllid treatments in commercial groves and prevent the spread of Huanglongbing, the ACP/HLB Task Forces in Santa Barbara and Ventura counties have established winter area-wide treatment dates.
Area-wide management is a strategy where growers in a specific area coordinate treatment efforts to maximize the impact on psyllid populations in areas where the psyllid has become established. This process has been effectively implemented in Florida to help manage Asian citrus psyllid populations and here in California to manage the glassy-winged sharpshooter. To combat the psyllid, coordinated management is one strategy that provides the maximum impact on psyllid populations, making it essential that neighboring growers work together.
Area-Wide Treatment Dates by County
Santa Barbara County: Dec. 31, 2017 – Jan. 20, 2018
Ventura County: Dec. 1, 2017 – March 16, 2018
Area-wide management regions are divided into small manageable zones called Psyllid Management Areas (PMA) where a grower network is established to work together. Maps of the PMAs can be found here, and recommended ACP-effective insecticides can be found at ucanr.edu/sites/ACP/. Ventura County growers can view the PMA schedule here.
