Define "insecticide."

An insecticide is specifically defined as a type of pesticide that is designed to target and manage insect populations. These substances work by acting on the physiological and biological systems of insects, which allows them to effectively control or eliminate pest species that are harmful to crops, structures, or human health.

The focus on insects is crucial because this distinguishes insecticides from other types of pesticides, such as herbicides, which are meant to control weeds, or fungicides, which target fungal pests. Insecticides can come in various formulations, including sprays, granulars, and systemic options, making them versatile tools in integrated pest management strategies.

Understanding the precise definition of insecticides helps in developing effective pest management practices, ensuring that the treatments chosen are specifically suited for the pests being targeted, leading to more efficient and responsible pest control.
