Sometimes, chemical manufacturers recommend use rates in terms of the amount of active ingredient (A.I.) It's essentially like a percentage, which you could analogously refer to as "parts per hundred," but PPM is better suited to substances in much smaller concentrations. Adjuvant - Chemical added to a pesticide formulation or tank mix to increase its effectiveness or safety. If the label gives the pesticide application rate in volume units such as quarts or pints, then the amount was found in Step 1. This result suggests that the effect of a mixed pesticide only reduces the pest density to 74.6% of the post-treatment density treated with a single active ingredient. Cold test: Example: Calcium nitrate contains 15% N (0.15 x 75 = 11.25).
