Which pesticide formulation has the lowest concentration?

The formulation labeled as 8D indicates that it is a dilute formulation, which typically represents a lower concentration of the active ingredient compared to other formulations. In pesticide formulations, the letter or symbol often signifies the type of formulation and the concentration can generally be inferred from the number associated with it.

When comparing different formulations, the number typically indicates the concentration or specific measurement of the active ingredient. A formulation denoted with a lower number, such as 8D, suggests that it contains less of the active ingredient than others like 4F, 10WP, or 25G.

In contrast, formulations like 4F (which stands for a flowable formulation), 10WP (wettable powder), and 25G (granular formulation), suggest higher concentrations based on their respective numerical values. The presence of higher numerical values correlates to higher concentrations in those formulations. Thus, 8D is recognized for having the lowest concentration of the active ingredient among the options provided.
