Maui Diamondback Moth Pesticide Resistance Management Program, insecticide spray schedule for the second half of the 2021 calendar year. The insecticide spray schedule is from July through December, based on insecticide bioassay results conducted in May, 2021. On Maui, the bioassay test results showed an increased resistance to Coragen and Radiant, and these pesticides will continue to be removed from the insecticide resistance management program. It’s VERY IMPORTANT that you follow the DBM Pesticide Resistance Management Program spray schedule to avoid a buildup in insecticide resistance. Until further notice, please follow the insecticide rotation spray schedule. Thank you for your commitment to the program. If you have any questions, please email me at firstname.lastname@example.org.
