Which formulation does the abbreviation WP represent?

The abbreviation WP stands for "wettable powder." This formulation type is a dry formulation that consists of solid particles, which can be mixed with water to form a suspension. Wettable powders are commonly used in pest control because they allow for more uniform application and effective pesticide distribution when sprayed. When water is added, the wettable powder creates a slurry that can easily adhere to plant surfaces and provide effective pest control while also minimizing drift and exposure hazards.

Other formulations, like emulsifiable concentrates or granules, have different properties and methods of application, which wouldn’t apply to the characteristic and effective nature of wettable powders. The terminology in pesticide formulations is important for understanding how to properly mix and apply them, which directly influences their effectiveness in pest management strategies.
