Mississippi State University has published the “2016 Insect Control Guide for Agronomic Crops” in a free, downloadable version. A print edition will be available at county Extension offices in January.cotton,
The updated guide has removed pyrethroid insecticides for bollworm control for all crops because of resistance and poor control.
