Hessian Fly

Foliar Insecticides for Hessian Fly Control

This page presents the results of experiments on foliar insecticides for control of Hessian fly in the Southeast.* For specific insecticide recommendations please see the Pest Management Guide for your state.

This study from Beaufort Co., NC, showed that a foliar application of insecticide at the two leaf stage (15 days after planting) controlled early season Hessian flies.  Wheat was planted around October 20.

An additional study from North Carolina that shows the efficacy of this early season spray.

Foliar insecticide sprays can also be used in spring to rescue fields that are heaviliy infested with Hessian flies. At this time there may be less yield potential, because the plants have already been damaged.
