What is one advantage of using wettable powders as a pesticide formulation?

The selection of having low risk of spills during storage as an advantage of using wettable powders as a pesticide formulation is insightful. Wettable powders are typically stored in dry conditions and, once mixed with water, create a suspension that adheres well to surfaces. This formulation helps to mitigate the risk of leaks or spills, making them safer to handle and store compared to liquid formulations which can easily spill and create hazardous conditions.

Additionally, wettable powders often allow for precise application since they can be mixed in controlled amounts, minimizing the likelihood of spills during the preparation and application processes. This enhances their overall safety and usability, particularly in terms of managing the environmental impact and maintaining the integrity of storage areas.

The other choices describe aspects that are not inherent benefits of wettable powders. For instance, high concentration of active ingredients can vary based on the specific formulation, and wettable powders do often require proper agitation to ensure the active ingredients are well-dispersed. Also, while they may have less visible residue compared to some formulations, this is not a definitive characteristic and can depend on various factors, including the specific application method and environmental conditions.
