Syngenta launches Quadris Top fungicide

May 17, 2012  By Press release

May 17, 2012, Guelph, Ont – Syngenta Canada Inc. recently announced the registration of Quadris Top, a pre-mix fungicide for the control of a broad spectrum of diseases in both potato and vegetable crops.

Quadris Top contains two active ingredients: azoxystrobin (a Group 11 strobilurin fungicide) and difenoconazole (a Group 3 triazole fungicide) with translaminar and xylem-systemic properties for preventative control of target pests.

“Quadris Top is an exciting evolution of an already trusted and effective fungicide,” stated Eric Phillips, asset lead for fungicides and insecticides for Syngenta Canada Inc. “With a dual mode of action, Quadris Top provides the disease control growers have come to appreciate with Quadris, along with the addition of the active ingredient difenoconazole for enhanced performance.”


Specifically, in potatoes, Quadris Top protects against early blight (Alternaria solani). Other key diseases controlled in potatoes include black dot (Colletotrichum coccodes), brown spot (Alternaria alternata) and Botrytis leaf blight (Botrytis spp.).

In vegetable crops, Quadris Top provides protection against leaf blight and Cercospora leaf spot in carrots; purple blotch, leaf blotch, Stemphyllium leaf blight, Botrytis leaf blight and downy mildew in bulb vegetables; Ascochyta blight and Anthracnose in dried shelled peas and beans; Mycosphaerella blight in field peas; plus, several other diseases in a wide variety of horticultural crops.

Quadris Top can be applied by ground or air (for potatoes only). It is a disease resistance management tool, and should be used in a fungicide spray program alternating with other modes of action.
