Herbicide Injury: Diphenylether (PPO) Herbicides (blazer, reflex) injury on Soybeans


Return to Herbicide Injury Gallery

PPO herbicides cause contact burning injury on the leaves, but newer leaves will not be affected.

PPO herbicides cause contact burning injury on the leaves, but newer leaves will not be affected. New leaves that are not fully axpanded at the time of spraying may appear twisted or crinkled without having the necrotic spotting. Injury symptoms may occur within a few hours after application. The canopy greens up again as new leaves emerge. For more information see Blazer and Reflex.
