What characterizes a selective pesticide?

A selective pesticide is designed to target specific pests while minimizing impact on non-target organisms. This characteristic allows it to effectively control the intended pest population without causing significant harm to beneficial insects, plants, or other wildlife in the environment.

The focus of selective pesticides lies in their mode of action, which primarily affects the physiological or behavioral aspects of the targeted pest. For example, certain herbicides may disrupt specific biological functions unique to particular weeds while sparing desirable crops or other plants. This balance helps maintain ecological integrity and supports beneficial organisms such as pollinators and natural pest predators.

In contrast, options that suggest the pesticide affects only non-target organisms or affects all types of organisms equally do not accurately describe a selective pesticide, as their defining feature is the targeted approach in controlling specific pests. Additionally, affecting both the targeted pest and beneficial organisms would suggest a broader impact, which contradicts the fundamental principles of selectivity in pesticide formulation.
