Revysol Fungicide from BASF Gets EPA Registration

New active ingredient available in 2020 as Veltyma in corn, Revytek in soybeans.

For the 2020 growing season, farmers will have a new fungicide for a host of crops, including corn and soybeans. 

BASF announced June 27 it has received EPA registration for Revysol, the industry’s first fungicide to use the active ingredient isoporopanol azole, which "...provides fast-acting and long-lasting disease control for a broad range of crops and disease combinations," the company said in a statement to Agriculture.com. Revysol has a unique molecular structure that gives it the ability to flex to various conformations, providing more flexibility to fight a broad spectrum of diseases and control resistant strains. In addition, it offers longer residual activity than competitors," BASF says.

In corn, its brand name will be Veltyma fungicide. BASF officials say it will give excellent control of major corn disease including gray leaf spot, northern corn leaf blight, tar spot, and southern rust. 

Research from Iowa State University in 2018 showed that corn treated with Revysol fungicide consistently outperformed other fungicides in suppressing gray leaf spot, when applied at the VT-R1 stage at a 7-ounce-per-acre use rate.

In soybeans, its brand name will be Revytek fungicide. BASF officials say it will give excellent control of frogeye leaf spot, septoria, target spot, and Asian soybean rust.

BASF says Revysol features several improvements over DMI fungicide products. These improvements include the following:

  • Application for a wide variety of crops, including corn, soybeans, grapes, potatoes, and sugar beets.
  • Faster fungicide uptake by the plant, leading to immediate disease-protective action.
  • Quick absorption leading to quick rainfastness and low water solubility, which allows the active ingredient to move through the plant for longer residual activity. 
  • Curative activity, or postinfection applications, made prior to symptoms developing, can help stop the disease from progressing and save yield. 

“Revysol fungicide will give growers the confidence to manage disease and resistance effectively while reducing their exposure to weather-related risks,” says 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.” 

BASF has spent several years of research and discovery to develop Revysol, accoring to a company spokesperson. "Revysol fungicide is an original BASF innovation. It is not a product we received in the acquisition. This new AI is the result of years of BASF research and expertise. It was designed to meet the highest level of regulatory standards while helping growers manage their toughest disease challenges, including resistant plant pathogens. Growers now have access to an outstanding new tool for disease management," she said in a statement.

In addition to corn and soybean products, the Revysol AI will be available in Provysol fungicide for potatoes, sugar beets, and peanuts, and Cevya fungicide for grapes, almonds, pome, and stone fruits.
