Syngenta seeks OKs for mesotrione on soy
Syngenta has applied to the US and Canadian authorities for approval of its established maize herbicide, mesotrione, on genetically modified mesotrione-tolerant soybeans. Syngenta and Bayer CropScience are co-developing soybeans with tolerance to mesotrione, isoxaflutole and glufosinate-ammonium, with a launch expected between 2015 and 2020 ( Agrow No 659, p 23). Mesotrione will provide pre- and post-emergence control of weeds such as waterhemp and pigweed ( Amaranthus spp) and lambsquarters ( Chenopodium album). Mixtures of mesotrione, isoxaflutole and glufosinate-ammonium will provide “overlapping efficacy with residual control to help mitigate the evolution of herbicide-resistant weeds”, Syngenta points out.
