Herbicide available as premix formulationSyngenta announced Prefix herbicide is now registered as a premix formulation, which will offer growers superior weed control with a new level of convenience and flexibility. The premix was granted registration on May 15, by the U.S. Environmental Protection Agency, and will be available for the 2008 growing season. For the current growing season, Prefix is available to growers as a co-pack. Prefix, a pre-emergence herbicide for soybeans, was performance tested as a co-pack in 2006 on more than 50,000 acres. Syngenta expects growers to use Prefix CP co-pack on more than 500,000 acres in 2007 because of its excellent performance on tough weeds the previous year. By delivering residual control of tough-to-control broadleaf weeds and grasses early in the season, Prefix helps growers start the season right to capitalize on their crop's true yield potential. Prefix is composed of two active ingredients, S -metolachlor and fomesafen, which provide exceptional broadleaf weed and grass control in both conventional and glyphosate-tolerant soybeans. Offering two modes of action, Prefix not only controls troublesome weeds like common ragweed, waterhemp and Palmer pigweed, but also helps growers fight against glyphosate and ALS resistance in their fields. Syngenta recommends the use of pre-emergence, residual herbicides on glyphosate-tolerant soybean acres following 2-1-2 as a resistance management guideline for corn and soybean growers, which means no more than two applications of glyphosate on one field over a two-year period. Prefix fits well in this program and also widens the application window for post emergence herbicide applications, if necessary.
