AB  - Increased usage of herbicides means increased injury to sensitive plants. Signs of chemical injury include cupped, chlorotic leaves, lack of apical dominance, enlarged bud size, parallel leaf venation, stem lesions, abnormal stem coloration, and nastic growth. Identification of weed-killer injury is difficult, requiring knowledge of individual species as well as detailed investigation and research.
