¹Mode of action. NC = not classified..
² Efficacy ratings denote the relative ability of a pesticide to control its target. The ratings are E = excellent, G = good, F = fair/suppression; P = poor, and ND = no data. Efficacy ratings are based on the inherent toxicity of the pesticide against its target, the likelihood that the target will contact or ingest the product as applied, duration of impact on the target, and undesired effects, such as negative impacts on natural enemies that could lead to future pest outbreaks.
³ Rate per acre per application. Refer to the product label for maximum use rate per season.
⁴ Reentry interval.
⁵The minimum pre-harvest interval. Some products do not list PHI.
