Glyphosate Injury on Grape
Return to Abiotic Disorders
Glyphosate (e.g., Roundup) herbicide injury symptoms occurring at the time of exposure include crinkled leaves with cuplike depressions between major veins. Late season injury results in multiple stunted shoots emerging from nodes the following season. Damage may not be evident until the following year if vines are exposed to glyphosate after mid-July.
