What does the abbreviation WP stand for?

The abbreviation WP stands for "Wettable Powder." This term refers to a type of formulation commonly used in pesticide applications. Wettable powders are solid particles that can be mixed with water to form a suspension, making them easier to apply through spray equipment. This formulation allows for a more even distribution of the active ingredient over the target surface and helps improve adherence. Wettable powders are favored in various pest control situations due to their effectiveness in managing pests while minimizing off-target drift, as the powder is designed to disperse well in water when mixed appropriately. Understanding this formulation is crucial for pest control applicators as it affects how products perform and how they should be applied in the field.
