Mar 31, 2010Revus Approved for Shorter Entry Interval
Syngenta Crop Protection announced that EPA has approved a shorter Restricted Entry Interval (REI) for Revus fungicide. Revus, which previously required an REI of 12 hours, now has an REI of four hours, offering greater flexibility and ease of use.
Revus, which was introduced in February 2008, 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. Revus is labeled for use on grapes and vegetables, including bulb, fruiting, leafy and brassica vegetables, as well as cucurbits.
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, according to the company.
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. Product used with the shorter REI must carry a label designating a four-hour REI.
