What does the label Alpha 40 WP indicate about the concentration of active ingredient?

The label Alpha 40 WP indicates that the product contains 40% active ingredient by weight. In pesticide labeling, the number preceding any designation such as "WP" (which stands for Wettable Powder) typically reflects the concentration of the active ingredient contained within the formulation. Therefore, when you see "40" in "Alpha 40 WP," it clearly conveys that 40% of the total product is comprised of the active ingredient responsible for pest control.

This understanding is crucial as it helps pesticide applicators determine the appropriate dosage and effectiveness of the product for their intended use. Knowing the concentration allows users to make informed decisions when mixing and applying the pesticide, ensuring both efficacy and safety while minimizing environmental impact.
