Syngenta announces that Orondis fungicide is now approved for use by the U.S. Environmental Protection Agency (EPA) as the first fungicide in the Fungicide Resistance Action Committee's ( FRAC) group U15.
Pending state registrations, Orondis could be available for the 2016 season.
Orondis contains the active ingredient oxathiapiprolin and offers a new mode of action for control of economically important soil and foliar diseases caused by Oomycete fungi in vegetables, potatoes, and tobacco.
Syngenta secured a license to develop and market products containing oxathiapiprolin from DuPont in 2013 and has exclusive rights in North America for foliar and soil use on vegetables, potatoes, tobacco, and other specialty crops.
A Syngenta spokesperson calls Orondis an excellent foundation fungicide and offers growers a new tool in their disease control programs. Its new mode of action complements and enhances the company’s diverse fungicide portfolio.
Orondis will be marketed as three multi-packs of separately registered products:
- Orondis and Ridomil Gold fungicide for control of soil-borne Oomycete diseases in vegetables and tobacco;
- Orondis and Bravo fungicide for control of downy mildew and late blight in potatoes and vegetables; and
- Orondis and Revus fungicide for control of downy mildew and late blight in leafy vegetables (lettuce and spinach), potatoes, tobacco, and other vegetables.
Pre-mix products will be developed combining these products. When approved by the EPA and states, the products will be sold under the following brand names: Orondis Gold fungicide (Orondis and Ridomil Gold); Orondis Opti fungicide (Orondis and Bravo); and Orondis Ultra fungicide (Orondis and Revus).
A company news release says Orondis showed outstanding efficacy in trials at significantly lower active ingredient rates, compared with other fungicides. It demonstrated an ability to greatly reduce disease severity in treated fields and provide measurable improvements in yield.
