Don't Spread the Asian Citrus Psyllid

CPDPC endorses “Best Practices for Growers in Response to HLB in California.”

    To provide California citrus growers with a strong toolbox of options to protect their orchards from Huanglongbing (HLB), the Citrus Pest & Disease Prevention Committee has endorsed the following “Best Practices for Growers in Response to HLB in California.” The recommendations – which are grouped based on a grower’s proximity to an HLB detection – represent the most effective tools known to the citrus industry at this time and are meant to supplement the California Department of Food and Agriculture’s required regulatory response.

    Growers are encouraged to use as many methods as feasible for their operation in order to limit the spread of the Asian citrus psyllid (ACP) and HLB, as the cost to manage the Asian citrus psyllid is far less than any potential costs or loss to the industry should HLB take hold throughout our state.
