The first spray is applied at 250 DD50 after the biofix. A second spray may be applied 10-14 days later. If pressure is not overly severe, one spray, applied at 360 DD50 after the biofix, is sufficient. 1260 DD50 after the biofix date. If CM pressure is severe, that application should be followed by another one in 10-14 days.
CM is controlled by the same synthetic insecticides as plum curculio and apple maggot.
The use of pheromones to disrupt CM mating is being investigated in western United States fruit producing regions.
