Phytotoxicity means harmful effects of a chemical on plants, causing undesirable injury to the plant tissue. It describes negative reactions such as leaf burn, curling, stunting, chlorosis, or distortion that can result from pesticide applications, drift, improper rates, or incompatible tank mixes. It’s not about beneficial growth effects, toxicity to animals, or improvements in yield. Understanding phytotoxicity helps you choose labeled products for a specific crop, apply them at the correct rate and timing, and take precautions to protect non-target vegetation.
