How to Manage Pests

Pests in Gardens and Landscapes

Herbicide injury

Herbicides used to control weeds near grapevines may drift and cause slight chlorosis and parallel vein construction of newly developing shoots. Leaves may be distorted and cupped, and flowers may be aborted.

Solutions

Herbicide injury can be minimized by reading the label and following the instructions carefully. Keep spray and drift off grape foliage to avoid injury. Grapes are especially susceptible to injury from summer and fall applications.
