Group 1 herbicides for green foxtail in field corn
There are 2 Group 1 active-ingredient groups rated good or excellent for green foxtail in field corn, with products labeled for field corn.
Group 1 mode of action (MOA) options
Group 1 is a herbicide mode of action (MOA) group. Treat it as one resistance-management check, not as the whole program.
Every listed product is labeled for field corn. Ratings are shown when each weed guide that rates this weed stays at good or excellent for the active-ingredient group. If a guide gives a range, the weaker end of the range has to be good or excellent.
Based on 1 weed guide, 2 active-ingredient groups are rated good or excellent for green foxtail in field corn.
