Which type of pesticide forms gases or vapors toxic to plants, animals, and microorganisms?

  1. Fungus

  2. Flowable

  3. Foaming Agent

  4. Fumigant

The correct answer is: Fumigant

Fumigants are types of pesticides that form gases or vapors that are toxic to plants, animals, and microorganisms. This makes them particularly effective for controlling pests in enclosed spaces or soil. Fumigants can penetrate cracks, crevices, and soil to target pests that are not easily reached by other types of pesticides. This mode of action distinguishes fumigants from other forms like fungicides, flowables, or foaming agents, which work differently to control pests.
