Minnesota Pesticide Applicator Practice Test

In the case of "Sevin 50WP," the designation "50WP" indicates that the product contains 50% active ingredient by weight. Therefore, if you have an 80 lbs container of this pesticide, you would calculate the amount of active ingredient by taking 50% of that total weight.

To find the active ingredient content, you multiply the total weight of the container by the percentage of active ingredient:

80 lbs (total weight) x 0.50 (50% active ingredient) = 40 lbs of active ingredient.

This calculation shows why the amount of active ingredient in an 80 lbs container of "Sevin 50WP" is 40 lbs. Understanding how to interpret the labeling of pesticide products is crucial for effective and safe pesticide application.
