Notes: Pesticides registered for pest control on a given food crop can also be used for that food’s seed crop, unless prohibited. For pesticide recommendations in addition to those listed below, see the appropriate food crop section in this handbook.
Modes of action are important criteria in selecting insecticides so as to prevent the development of resistance to insecticides. Rotate chemicals with a different mode-of-action (MOA) group number, and do not use products with the same mode-of-action group number more than twice per season. For example, pyrethroids have a group number of 3A; chemicals with a 3A group number should be alternated with chemicals that have a group number other than 3A.
