Leaf rollers are small caterpillars that attack many of our small fruits. The larva spins a silken thread and folds over the edges of the leaves, feeding on the inside tissue. It spends the winter as a pupa inside this fold in the fallen leaves. Infestations may occur in the same field year after year if control measures are not used. Insecticide applications should be made before leaves have become folded to any extent to be effective, since they must come in contact with leaf rollers before they construct their silken cases.
Thorough coverage is necessary.
Apply choice of insecticide to the point of runoff. Be sure the chosen insecticide is labeled for use on the crop before applying. Refer to product labels for rates, usages, and precautions.
