Preserving Biocontrol Agents

Tuesday May 16, 2017 4:04pm
Natural enemies (NE) are crucial to the long-term stability of management programs. Pesticides need to be chosen not only on the basis of efficacy against the pests, but also by minimizing their effect on natural enemies. DAS provides both the effects on pests and on the key natural enemies.

Leafroller and Codling Moth Movement During the Season

Tuesday May 16, 2017 4:04pm
Movement of codling moth and leafrollers into your orchard can be the start of serious damage. Both CM and leafrollers can easily fly 5-7 miles in a single night and their reproduction is as high as those that do not fly. Although 5-7 mile flights are common, the likelihood of the moths coming to your orchard in high numbers is directly related to wind speed, distance from the source, and the environment in between the source and your orchard.
