Prepared by Ames Herbert, Virginia Tech, Jack Bacheler, North Carolina State University, Dominic Reisig, North Carolina State University

The insecticide landscape has become increasingly more complicated with generic products and the advent of premixes, or co-packs.  A premix is an insecticide product that contains multiple active ingredients.  The amount of active ingredient can vary widely, which can influence efficacy of various pests.  This table seeks to document many popular options and various chemistries for both bollworm and stink bug on cotton.  Not all products could be included for simplicity’s sake, but we have tried to capture some of the major ones.
