What does a defoaming agent do in a spray mixture?

  1. Promotes foaming to aid in even coverage

  2. Induces foam to protect plants from pests

  3. Increases the toxicity of the pesticide

  4. Reduces foaming caused by agitation

The correct answer is: Reduces foaming caused by agitation

A defoaming agent is added to a spray mixture to reduce foaming caused by agitation. When pesticides are mixed or agitated in a tank, it can create excessive foam which can be problematic for accurate application and coverage. By adding a defoaming agent, it helps to control and reduce the foam formation, ensuring that the pesticide mixture can be applied evenly and effectively onto the target surfaces.
