BASF’s Revysol fungicide gets EPA registration, could help with early blight resistance

basf revysolBASF received the U.S. Environmental Protection Agency (EPA) registration for Revysol fungicide, its newest active ingredient (AI). The first and only isopropanol azole of its kind in the market, the AI provides fast-acting and long-lasting disease control for a broad range of crops and disease combinations.

In recent BASF trials, Revysol has shown exceptional biological performance against several economically significant diseases, including northern corn leaf blight in corn, cercospora leaf spot in sugarbeets, frogeye leaf spot in soybean, and powdery mildew in grapes.

For growers challenged with resistance and seeking to maximize their yields, Revysol fungicide offers unique benefits when compared to DMI fungicides.

Curtis Rainbolt, technical service representative for BASF, said Revysol is a group 3 fungicide, which have been around for quite some time, but called it a “new generation” group 3. It hasn’t been used on potatoes much, so resistance should’t be an issue.

“When you look the structure of the molecules, it’s really different,” Rainbolt told Spudman during Potato Expo in January. “It has a different spectrum of disease control than what those older ones do.

“It’s really going to do well in potatoes.” Rainbolt cited early blight as a particular disease of promise.

“Revysol fungicide will give growers the confidence to manage disease and resistance effectively while reducing their exposure to weather-related risks,” said Paula Halabicki, BASF technical marketing manager. “The treatment offers longer residual properties than its competitors and protects against many weather conditions like drought, hail, frost and heat.”

The AI will be available in several customized products, Provysol fungicide in potatoes, sugar beets and peanuts.

Revysol, and its related product brands, will be available to growers for the 2020 planting season.
