Group 2 herbicides for morningglory in rice
There are 3 Group 2 active-ingredient groups rated good or excellent for morningglory in rice, with products labeled for rice.
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 rice. 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, 3 active-ingredient groups are rated good or excellent for morningglory in rice.
