What is a potential risk associated with using wettable powders in pesticide applications?

Using wettable powders in pesticide applications can lead to abrasion of application equipment due to the physical nature of the powders. Wettable powders are finely ground particles that, when mixed with water, can create a slurry that is often abrasive. When this slurry passes through pumps, hoses, and nozzles, the finer particulates can wear down the components of the spraying equipment over time. This wear can lead to leaks, reduced efficiency, and a higher likelihood of equipment failure, necessitating more frequent maintenance or replacement of parts.

While high toxicity levels, excessive residue, and limited shelf life can be characteristics of certain pesticides, they are not inherently tied to wettable powders. The primary concern with wettable powders relates to their potential for mechanical wear and tear on the application equipment. Understanding this risk is important for those in the industry to ensure longevity and effectiveness of equipment and to maintain safety during pesticide applications.
