Vegetable fungicide offers new chemistry

Syngenta Crop Protection has picked up what’s known as a “NAFTA label” for registration of a new fungicide for vegetable crops across Canada.

The company’s Canadian wing on Friday announced the registration of Revus, which it said protects against oomycete fungi in crops including potatoes, tomatoes, peppers, brassica vegetables, bulb vegetables, cucurbit vegetables, leafy vegetables and grapes.

Syngenta bills Revus as the first mandelamide fungicide on the market, combining mandipropamid with a unique “LOK+FLO” technology. Upon application, mandipropamid locks (LOK) tightly to the waxy cuticle of treated leaves, quickly becoming rainfast and establishing a barrier to prevent fungi from taking hold.

Meanwhile, the company said, a steady supply of fungicide enters the leaf, flowing (FLO) through the inner tissue by translaminar activity to protect both sides of the leaf with a long-lasting reservoir of the active ingredient.

“Revus is an excellent product for resistance management when used in a rotation with other classes of fungicides that are labeled for the same disease,” said Wayne Bennett, the company’s brand manager for Eastern Canada, in its release.

“Revus provides anti-germination effects, which means disease spores land on the plant and the product prevents them from germinating. When used in a preventative program, this can dramatically reduce the level of new infections in a field.”

In Canada, Bennett said, “it often takes years to expand a label to this magnitude.

“We are particularly pleased with the collaboration efforts between the Canadian and U.S. regulators which resulted in a product with a NAFTA label,” he said. “This allows free movement of Revus between Canada and the U.S. and ensures Canadian growers have access to the same tools as their neighbours to the south.”
