Corteva Agriscience Unveils Three New Herbicides — TerraVue™, DuraCor™ and ProClova™

The U.S. Environmental Protection Agency (EPA) has registered two new Corteva Agriscience herbicides — DuraCor™ and TerraVue™ — for the 2020 season and is evaluating a third — ProClova™. DuraCor and TerraVue herbicides are powered by Rinskor™ active, a new active ingredient in the vegetation management market, designed to deliver superior weed and brush control with tolerance to grasses, forbs, shrubs and other desirable plants. That combination provides two-fold advantages to vegetation managers. Rinskor received the American Chemical Society’s 2018 Green Chemistry Challenge Award.

DuraCor effectively controls common rangeland and pasture weeds, such as thistles, ragweed, horsenettle, pigweed and others. TerraVue can be used on roadsides, utility rights-of-way, natural areas and wildlife management areas, including grazed areas in and around these sites, among other locations. Both products will be available for the 2020 application season.

ProClova is designed to provide cattle producers access to a broad-spectrum weed control product that preserves white clover and annual lespedeza, and all their benefits. Pending EPA registration, Corteva anticipates making ProClova available to livestock producers for the 2021 season.
