There are 6 Group 2 active-ingredient groups rated good or excellent for f = fair) crop tolerance (g = good in soybeans, with products labeled for soybeans.
Group 2 mode of action (MOA) options
Group 2 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 soybeans. 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.
