What is a characteristic of wettable powders (WP)?

• A. They form a solution when mixed with water
• B. They are non-hazardous when inhaled
• C. They form a suspension when mixed with water
• D. They are easier to apply as a granular form

Answer: (C)

Wettable powders (WP) are designed to disperse in water, creating a suspension rather than a true solution. When WP is mixed with water, the fine particles do not dissolve but rather remain suspended in the liquid, allowing for uniform distribution of the pesticide when applied. This characteristic is crucial in pesticide formulations, as it ensures that the active ingredient can effectively contact the target area during application. The formation of a suspension means that applicators must agitate the mixture to maintain the particles in suspension before and during spraying. This is particularly important for achieving effective pest control since the distribution of the active ingredients must be even to minimize the chance of underdosage or overdosing a target area. Other options refer to properties that do not accurately describe wettable powders. For example, wettable powders do not form solutions, they can pose inhalation hazards if proper safety measures are not taken, and their application is generally different compared to granular forms, which have their unique set of characteristics and uses.
