What does the abbreviation WP stand for in pesticide formulations?

1. Wettable Powder

2. Water Phased

3. Washable Product

4. Worm Powder

The correct answer is: Wettable Powder

The abbreviation WP in pesticide formulations stands for Wettable Powder. This type of formulation consists of solid pesticide particles that can be mixed with water to form a suspension. Wettable powders are often used because they can provide effective control of pests and diseases while allowing for a more targeted application. When mixed with water, the wettable powder creates a slurry, which adheres well to plant surfaces and facilitates the distribution of the active ingredient. This formulation type is particularly valued for its stability and ease of handling during transport and storage. The option referring to "Water Phased," "Washable Product," or "Worm Powder" does not accurately describe established pesticide formulations; they do not reflect common industry terminology or practices related to pesticide application. Thus, Wettable Powder is the correct answer, as it directly correlates with a recognized and widely used pesticide formulation.
