| Basis of Selectivity | Selectivity of flumetsulam in soybeans is based on metabolism. Basis of selectivity of s-metolachlor is not established. |
| Application Methods | Surface preplant, preplant incorporated or preemergence. |
| Residual Activity | The most significant means of dissipation of both s-metolachlor and flumetsulam is microbial degradation. Provides season-long residual control of annual broadleaf and grass weeds. Rotational crops are winter wheat, spring wheat, spring barley, soybeans, common beans (dry, snap), lima beans, peas, field corn, seed corn. |
