Group 1 herbicides for kochia in barley
There are 2 Group 1 active-ingredient groups rated good or excellent for kochia in barley, with products labeled for barley.
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 barley. 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 kochia in barley.
| Example product | Active ingredients | MOA group | Ratings checked |
|---|---|---|---|
| Wolverine EPA 264-1075; same active ingredients on 1 other branded product | bromoxynil, fenoxaprop-p-ethyl, and pyrasulfotole | 1, 6, 27 | ND Weed Guide 2026: G-E (PDF) |
| Axial Star EPA 100-1389 | fluroxypyr 1-methylheptyl ester and pinoxaden | 1, 4 | ND Weed Guide 2026: E (PDF) |
Rating legend: E=excellent, G=good, F=fair, P=poor, N=no control. A range such as G-E means the guide gives a range; 'a' after a rating (e.g., Ga) means the guide assumes its recommended additive.
