Syngenta names oxathiapiprolin fungicide
Syngenta has named its new oxathiapiprolin-based fungicide Orondis. The product is for the control of late blight (Phytophthora infestans), downy mildews and Phytophthora spp root and stem blights on vegetables, potatoes and tobacco. Syngenta has a global licence to the active ingredient from DuPont. The latter plans to market the fungicide as Zorvec and recently forecast peak annual sales at $100-500 million. US approval decisions have been scheduled for the second quarter of this year. Oxathiapiprolin comes from the piperidinyl thiazole isoxazoline class of fungicides. It has a novel mode of action with no known cross-resistance to other products, Syngenta points out. "Compared to other fungicides, Orondis brings a paradigm shift in oomycete disease control with ten to 100 times lower ai rate and consistent efficacy," says fungicide technical product lead Paul Kuhn.
