Phytotoxicity refers specifically to the injury or damage inflicted on sensitive plants due to exposure to chemicals, such as pesticides or herbicides. This concept is important in pest control because it highlights the potential negative side effects that chemical treatments can have on non-target plant species. When a chemical intended for pest control is applied, it may affect plants in various ways, including leaf burn, stunted growth, and even plant death, depending on the sensitivity of the species and the concentration of the chemical. Understanding phytotoxicity helps pest control professionals make informed decisions to protect desirable plants while managing pest populations effectively.

Other options reflect different concepts in plant and pest management. Resistance of plants to pests involves the natural ability of certain plants to withstand or repel pest attacks without chemical intervention. The growth of invasive plant species pertains to how certain plants can thrive and spread aggressively in new environments, often outcompeting native species. Lastly, stimulating plant growth through chemical exposure relates to the use of fertilizers or growth enhancers rather than focusing on the detrimental effects of chemicals, which is the essence of phytotoxicity.
