Revus Fungicide Receives Federal Registration

New chemistry protects against Phytophthora and downy mildews

Syngenta Crop Protection.

Greensboro, North Carolina (February 26, 2008)--Syngenta Crop Protection announced today the federal EPA registration of Revus™ fungicide for use on Brassica vegetables, bulb vegetables, cucurbit vegetables, peppers, leafy vegetables and grapes. Revus contains the active ingredient mandipropamid, the first mandelamide fungicide on the market, and targets oomycete fungi, including the pathogens that cause Phytophthora blight, late blight and downy mildews. State registrations or specific crop and/or pest uses may still be pending in certain states. Please check with your state regulatory agency to determine registration status.


“Revus represents an exciting new chemistry with outstanding performance on some of the most challenging pathogens in vegetables and grapes,” said David Laird, Syngenta fungicide brand manager. “Revus also provides excellent rainfastness and efficacy.”

Revus exhibits LOK + FLO™ technology, preventing spore germination and producing a barrier to prohibit further infection. Upon application, mandipropamid locks tightly to the waxy cuticle of treated leaves, quickly becoming rainfast and establishing a protective barrier to prevent fungi from taking hold. Meanwhile, a steady supply of the fungicide enters the leaf, flowing through the inner tissue by translaminar activity to protect both sides of the leaf with a long-lasting reservoir of the active ingredient. The rainfastness and photostability of Revus deliver excellent residual activity.

A mandelamide fungicide, Revus is a member of the carboxylic acid amide (CAA) class of chemistry, part of the Fungicide Resistance Action Committee’s Group 40. Members of the CAA class exhibit no cross-resistance to other classes of fungi, establishing Revus as an outstanding tool on its own in addition to being an integral part of an Integrated Resistance Management (IRM) program. And as a powerful, reduced-risk pesticide1, Revus is also an excellent Integrated Pest Management (IPM) tool.

“It’s always exciting to bring a new product to the market,” Laird added. “It’s especially exciting to deliver a tool to growers that raises the bar on performance and helps them tackle pathogens like Phytophthora and downy mildew fungi. Revus is a tool that can significantly improve the productivity and returns in vegetables and grapes.”

1A reduced-risk pesticide use is defined as one which “may reasonably be expected to accomplish one or more of the following:” (1) reduces pesticide risks to human health; (2) reduces pesticide risks to non-target organisms; (3) reduces the potential for contamination of valued, environmental resources, or (4) broadens adoption of IPM or makes it more effective. Revus satisfies all four of these criteria.
