What does the term phytotoxic mean?

Phytotoxic refers specifically to the ability of a pesticide or chemical substance to cause injury to a plant. This injury can manifest in various forms such as leaf burn, stunted growth, or discoloration. Understanding the concept of phytotoxicity is critical for applicators because it helps them assess the potential risks associated with using certain pesticides near or on sensitive plant species. Additionally, knowledge of phytotoxic effects enables applicators to make informed decisions about the appropriate chemical use and application methods to minimize harm to desirable plants while effectively managing pests. Recognizing that not all substances that affect plant health promote growth is also essential, as some may adversely impact plants, highlighting the importance of careful product selection and application strategies.
