Group 15 herbicides for f = fair) crop tolerance (g = good in soybeans
There are 10 Group 15 active-ingredient groups rated good or excellent for f = fair) crop tolerance (g = good in soybeans, with products labeled for soybeans.
Group 15 mode of action (MOA) options
Group 15 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.
Based on 1 weed guide, 10 active-ingredient groups are rated good or excellent for f = fair) crop tolerance (g = good in soybeans.
