Which term is used to describe a pesticide that can cause harm to plants?

The term "phytotoxic" specifically refers to substances, including certain pesticides, that can cause damage to plants. This damage can manifest in various forms, such as wilting, chlorosis (yellowing of leaves), stunted growth, or even plant death. Understanding phytotoxicity is crucial for those applying pesticides, as it emphasizes the need for careful application and consideration of the specific plants being treated, ensuring that the pesticide does not harm desirable vegetation while targeting pests or diseases.

While "toxic" broadly refers to anything that can cause harm to living organisms, it does not specifically address the plant-focused impact that "phytotoxic" conveys. Similarly, "insecticide" denotes a type of pesticide that targets insects specifically, without addressing potential plant harm. "Pestidal" is not a standard term used in the context of pesticide discussions.

Therefore, the most precise term for describing a pesticide that can cause harm to plants is "phytotoxic."
