Management Problem

Name: Herbicide Injury

Secondary Name:

Source: Usually occurs from accidental drift from applications within the orchard or nearby. Aerial applications tend to drift farther and may be more destructive. Phenoxy herbicides in the ester form are more volatile and therefore are more likely to create damage on unintended targets.

Description: Leaves become yellow and small, sometimes cupped or extremely misshapen. Symptoms vary by herbicide and amount. Young trees may be permanently damaged, older trees often recover.
