Which term describes pesticides that affect only a limited group of pests?

Explanation:
Understanding spectrum of activity is essential. Pesticides differ in how many pests they affect. Some are broad-spectrum, attacking a wide range of pests and often impacting non-targets as well. Others are narrow-spectrum, designed to affect only a specific, limited group of pests, which supports selective control and minimizes collateral damage. Therefore, the term that describes pesticides that affect only a limited group of pests is narrow-spectrum. The other terms describe different ideas: systemic refers to how the chemical moves through a plant after uptake, not the breadth of pests targeted, and contact refers to needing to touch the pest to be effective rather than the range of pests affected.
