Jan. 23, 2012 – Syngenta Canada Inc. is pleased to announce that Quadris Fungicide now has control of the disease, Black Dot, added to its label for use on potatoes.“Quadris is a well respected and well used fungicide because it delivers effective control of a multitude of challenging potato diseases,” stated Eric Phillips, Asset Lead for Syngenta Canada Inc. “With this label expansion to include control of Black Dot, potato growers now have one less disease to worry about.”
Black Dot, or Colletotrichum coccodes, is a common disease in potatoes. It is most often found on tubers but can affect all parts of the plant. On potato foliage, symptoms of the disease are nearly indistinguishable from early blight, and on tubers, it produces blemishes sometimes mistaken for silver scurf. Black Dot can significantly impact potato production, as it can affect the plant’s vascular system causing the plant to wilt; while below ground, it can cause severe rotting of roots, shoots and stolons, leading to early plant decline, discoloured tubers and reduced yields.
Quadris is a broad-spectrum, preventative fungicide with systemic properties. Optimum disease control is obtained when Quadris is used as a protective treatment prior to disease establishment. In addition to Black Dot, as a foliar spray, Quadris is also registered on potatoes for control of early blight (Alternaria solani) and late blight (Phytophthora infestans).
For control of Black Dot, Quadris should be applied on a 7 to 14 day interval, starting prior to disease establishment at a rate of 500 to 800 mL/ha.
