Determining Chlorantraniliprole Residual Activity Against Bollworm (Helicoverpa Zea) in Cotton

In 2020, at the Delta Research and Extension Center in Stoneville, MS, lab bioassays were conducted at weekly time intervals to evaluate the residual activity of chlorantraniliprole in cotton.  At the same time intervals, leaf samples were collected to determine chlorantraniliprole concentrations. Results from this study are still being analyzed.
