What is referred to as undesirable injury to plants?

Phytotoxicity refers specifically to the harmful effects that certain substances, especially chemicals or pesticides, can have on plants. This term encompasses a broad range of undesirable injuries that can manifest in various symptoms, such as leaf burn, stunted growth, or discoloration. It highlights the negative impact that these substances may impose on plant health, distinguishing it from broader concepts like plant vigor reduction, which may or may not stem from chemical exposure.

Understanding phytotoxicity is crucial in the field of pest control and turf management, as it emphasizes the importance of proper application techniques and dosage to minimize any potential damage to desirable plants while effectively managing pests and diseases.
