What is a general guideline for mixing small amounts of spray with wettable powder?

Using 1 tablespoon of wettable powder per gallon of spray solution is a widely accepted general guideline because it strikes a balance between effective pesticide performance and ease of mixing. Wettable powders require a specific amount of water to ensure they dissolve adequately and disperse evenly in the spray mixture, which is crucial for consistent application and optimal pest control.

This ratio allows for a sufficiently concentrated solution that enhances the efficacy of the pesticide while preventing issues such as sedimentation or clogging of sprayers. This guideline is particularly useful for applicators as it simplifies the mixing process and helps ensure the solution remains uniform, which is vital for achieving effective coverage on target pests.

Maintaining this established ratio contributes to both the safety and efficacy of pesticide application, making it an essential practice for professionals in the field.
