CheckMate MD

—a group of mating disruption products for the control of codling moth (CheckMate CM, CheckMate CM-F, Oriental fruit moth; CheckMate OFM Dispenser and CheckMate OFM-F or both species at the same time; Check- Mate CM-OFM Duel). The hand-applied dispensers should be placed in the orchards before the spring emergence of the pests (biofix) or when the moths are first detected in pheromone traps. Similarly to other mating disruption materials, the CheckMate products will not have an effect on female moths, eggs, or larvae.  The CheckMate pheromone dispensers (pouches) are placed on trees by hand and therefore require high labor input. The time of application, length of activity, number of dispensers per acre, and placement within the tree vary from species to species, and detailed instructions from the product label should be followed to achieve success. Mating disruption usually works better under lower pest pressure and may require supplemental insecticide treatments. It is recommended that mating disruption be used on the whole orchard or block. Most of CheckMate hand-applied MD products are OMRI listed (for more information, see “Using pheromones for mating disruption”).
