Monsanto plans US Warrant Ultra debut
Monsanto plans to introduce a microencapsulated formulation of the herbicide, acetochlor, in combination with fomesafen, as Warrant Ultra, in the US next year for use on soybeans and cotton. The product received EPA approval last month. It provides two modes of action for residual weed control, while fomesafen adds post-emergence control of "problematic" weeds such as waterhemp and Palmer amaranth (both Amaranthus spp), the company points out. The product controls glyphosate-resistant weeds and is seen as a useful resistance management tool in the cultivation of glyphosate-tolerant Roundup Ready crops. Monsanto introduced a microencapsulated formulation of acetochlor, as Warrant, in 2010.
