Effectiveness of Pesticides Used for the Control of Major Grape Pests in the Midwest. See label restrictions on use. Several species of insects and mites infest or feed on grapes in the Midwest.
Damage is direct to the berry clusters or indirect to vines, shoots, roots, or leaves.
Many of the pests are found only in certain regions, others only occasionally reach damaging population levels. Much of the potential for reducing pesticides used on grapes will be in the area of insect control. IPM methods have been developed for monitoring and controlling insects which allow the grower more flexibility in making decisions on whether or not insecticides are needed, alternative control methods that might be applied, which control measure to apply, and when to apply them. Suggested time to scout vineyard for damage or presence of specific pests.
