1 Rotate chemicals with a different mode-of-action Group number, and do not use products with the same mode-of-action Group number more than twice per season to help prevent the development of resistance. For example, the organophosphates have a Group number of 1B; chemicals with a 1B Group number should be alternated with chemicals that have a Group number other than 1B. Mode of action Group numbers ( "un" = unknown or uncertain mode of action) are assigned by IRAC (Insecticide Resistance Action Committee). For additional information, see their Web site at
2 Restricted entry interval is 7 days for cotton scouts.
3 Determined by amount of yearly rainfall; see label.
4 Do not apply after bolls open.
5 Brood poison at lower doses.
6 Determined by rate applied.
