A new fungicide, Orondis Ultra, has recently been released by Syngenta Canada to help control oomycete diseases, downy mildews and Phytophthora specifically in potatoes and vegetables. 

The new fungicide contains Mandipropamid and an active ingredient called Oxathiapiprolin.

Oxathiapiprolin will provide preventive and residual control at use rates much lower than fungicides currently on the market. In field trials, the active ingredient did not show cross-resistance to other fungicides and had exceptional rain-fastness. The fungicide is able to protect plants during active growing periods by moving across the leaves as well as up through the water-conducting vessels of the plant. Most notably, it protects potatoes from late blight caused by the oomycete Phytophthora infestans.

“Throughout the growing season, weather conditions can bring about high levels of moisture and temperatures that allow late blight to thrive and develop,” Eric Phillips, Syngenta Canada's product lead for fungicides and insecticides, said. “The residual control that Orondis Ultra provides allows growers to proactively manage late blight.”

Orondis Ultra can also be used on a variety of vegetables including head and stem brassica vegetables, bulb vegetables, leafy vegetables and cucurbit vegetables.

The fungicide will be on the market for consumer use this spring.
