Why is it important to frequently agitate the pesticide solution during mixing?

• A. To keep the solution uniform
• B. To increase potency
• C. To decrease mixing time
• D. To create more drift

Answer: (A)

Keeping the solution well mixed is essential because the ingredients in many pesticide formulations can settle or separate as you mix and as you operate the sprayer. Frequent agitation helps keep all components—active ingredient, diluent, and any carriers or adjuvants—in suspension so every gallon has the same concentration. This uniformity ensures the spray you apply is consistent in rate and coverage, meeting label directions and reducing the risk of under- or over-application. It also helps prevent settled materials from re-accumulating and causing nozzle clogging or uneven spray patterns. Agitation won’t make the product more potent, nor will it meaningfully shrink mixing time or increase drift; those are not outcomes you’re aiming for with proper agitation.
