  3. Metolachlor or S-metolachlor is a selective and systemic herbicide which control weeds by inhibiting the synthesis of long chain fatty acids. Metolachlor is one of the widely used herbicides on corn in Minnesota, and is also labeled for use on soybeans, potatoes, sugar beets, sunflowers, and tomatoes
  4. the sorption affinity of S-metolachlor. Similar Koc coefficients for metolachlor (mean &=249.250) and S-metolachlor (mean K0,=265.875) were observed in paired batch equilibrium studies. These data suggest that metolachlor and S-metolachlor are expected to be highly mobile to mobile in soil and water environments

• S-metolachlor has more of the S-isomer pair in each pound due to a selective manufacturing process, i.e., a 7.3:1 ratio is achieved (88% S and 12% R), making it more active than racemic metolachlor. S-metolachlor provides the same level of weed control at a 35 percent lower rate than generic herbicide brands containing the racemic metolachlor On March 11, 2019, EPA published in the Federal Register a final rule establishing tolerances for residues of S-metolachlor in or on several commodities based on the Agency's conclusion that aggregate exposure to S-metolachlor is safe for the general population, including infants and children. See ( 84 FR 8611) (FRL-9983-79) It is a selective herbicide for the control of annual grass weeds, yellow nutsedge, and some broadleaf species. Metolachlor is used in corn, peanuts, and soybeans. S-metolachlor, which contains a higher percentage of the more active of two isomers, was registered in 1997. Its formulations are soid under trade names such as Dual® Magnum®

  1. S-Metolachlor is the result of a proprietary breakthrough in the catalyst system of the manufacturing process for metolachlor. Metolachlor is a 1:1 mixture of R- and S- isomer pairs (1). The manufacturing process breakthrough allows for selective production of the more active isomer, S- metolachlor, in commercial quantities. S-Metolachlo
  2. S-Metolachlor has a wide application window and can be used pre-plant incorporated, early pre-plant, pre-plant, pre-emergence and early post-emergence. Post-emergence applications should be made before grasses exceed the 2 leaf stage. The product provides 4-6 weeks residual activity against newly emerging weeds
  3. At the lower use rates and with highly concentrated formulations containing up to 96% (w/v) active ingredient, the use of S -metolachlor will result in a substantial reduction of risk to applicators, consumers and the environment and the herbicide will continue to play an important role in sustainable weed-management.
