What is phytotoxicity?

• A. Injury to plants
• B. Toxicity to animals
• C. Degradation rate
• D. Residual life

Answer: (A)

Phytotoxicity is plant injury caused by a chemical or pesticide. It refers to adverse effects on the plant itself, such as leaf burn, chlorosis, necrosis, stunted growth, or deformities, rather than effects on animals. This is different from how fast a chemical degrades (degradation rate) or how long it remains in the environment (residual life), and it’s also distinct from toxicity to animals. When choosing products, understanding phytotoxicity helps ensure the treatment harms pests without injuring the crop or other plants.
