What is the purpose of a wetting agent with regard to pesticides?

Plants that complete their life cycle within a year
An adjuvant for reducing liquid surface tension
A device for pesticide application
A plant that germinates in the fall or winter

The correct answer is: An adjuvant for reducing liquid surface tension

Wetting agents, also known as surfactants, are substances added to pesticide formulations that reduce the surface tension of water. This allows the pesticide to spread more evenly across plant surfaces, increasing its coverage and effectiveness. Option A is incorrect because it defines annual plants, not wetting agents. Option C is incorrect because it refers to a different type of application device. Option D is incorrect because it describes a different type of plant.
