Syngenta Crop Protection announced today the federal registration of Revus Top fungicide.

The fungicide is a premix of two active ingredients, mandipropamid and difenoconazole, for use on potatoes and tomatoes against destructive oomycete pathogens. 

Revus Top, a 1-to-1 combination of mandipropamid, a carboxylic acid amide (CAA) fungicide and difenoconazole, a triazole fungicide (sterol inhibitor), provides protection against early blight and late blight, as well as a broad-spectrum of other tough diseases including black mold, black dot, Septoria leaf spot, anthracnose and other diseases.

The pre-mixed product has exhibited crop safety, good tankmix compatibility and effectiveness in Integrated Pest Management (IPM) programs.

State registrations or specific crop and/or pest uses may still be pending in certain states. Check with state regulatory agencies to determine registration status.

"Revus Top combines two powerful active ingredients into one protective fungicide, providing control of two of the most damaging diseases, late blight and early blight, in potatoes and tomatoes," said David Laird, fungicide brand manager for Syngenta.

Applied by ground, air or chemigation, the fungicide is rainfast as soon as spray droplets have dried. Through LOK +
FLO action, it locks tightly to the waxy cuticle of treated leaves and establishes a protective barrier to prevent fungi from taking hold. A steady supply of Revus Top enters the leaf, moving through the plant tissue via translaminar movement, protecting both leaf surfaces and providing long-lasting, preventive protection.

"Mandipropamid is a member of Fungicide Resistance Action Group 40, and difenoconazole is a Group 3 fungicide," said Laird. "With a powerful foundation from Revus Top protecting against a broad spectrum of diseases, growers can build a highly effective, sustainable defense against pathogens all season long."
