Pesticide Applicator Practice Test – Pass the Wisconsin Exam in 2025

Wettable Powders, also known as WP, are a type of pesticide that are used to control pests. They are typically derived from plant or mineral sources, and come in powder form. They are designed to be mixed with water and sprayed onto plants or crops. Option A, which states that WP are highly soluble in water, is incorrect because they actually do not dissolve completely in water. They remain in suspension, which allows for more contact with the pests being targeted. Option C, stating that WP dissolve quickly, is incorrect because it takes some time for WP to fully dissolve in water. Finally, option D, which says that WP provides immediate pest control, is incorrect because it actually takes some time for WP to fully take effect and provide control over pests. This leaves us with the correct answer, option B, which states that WP formulations have been known to wear out pumps and nozzles. This is because the particles in WP are fine and can easily clog equipment if not properly filtered. Therefore, it is important to use appropriate equipment and follow proper mixing instructions when using Wettable Powders.
