Syngenta announced that Orondis fungicide is now approved for use by the U.S. Environmental Protection Agency (EPA) as the first fungicide in the FRAC group U15. Pending state registrations, Orondis is expected to be available for the 2016 season.

Orondis contains the active ingredient oxathiapiprolin and offers a new mode of action for control of 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.

“Orondis is an excellent foundation fungicide and offers growers a new tool in their disease control programs,” said Bernd Druebbisch, fungicide product lead, Syngenta. “Its new mode of action complements and enhances our diverse fungicide portfolio.”

Orondis will be marketed as three multi-packs of separately registered products to customers:

  • 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
  • Orondis and Revus fungicide for control of downy mildew and late blight in leafy vegetables (lettuce and spinach), potatoes, tobacco and other vegetables

Premix products will be developed combining these products and, when approved by the EPA and states, 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).

“In extensive trials, Orondis has shown outstanding efficacy at significantly lower active ingredient rates, compared with other fungicides,” said Paul Kuhn, technical product lead, Syngenta. “It has demonstrated an ability to greatly reduce disease severity in treated fields and provide measurable improvements in yield.”
