The results of the 1996 multi-state evaluation of the COTMAN insecticide termination rules are presented. Small plot experiments produced no evidnece that yields would be reduced by terminating insecticide treatments when COTMAN suggests. No statistically significant differences in yields, gross revenues nor net revenues were detected in large plot comparisons between the COTMAN rules and full season insect control following growers' normal economic thresholds.
