Research-backed Solutions to Late Blight in Potatoes

August 9, 2018
This agronomic image shows late blight on a potato leaf.

Late blight thrives in cool, wet weather, and under such conditions can damage potatoes quickly. The first symptoms of the disease usually appear on lower leaves as small, light-to-dark green, circular or irregular-shaped water-soaked spots. White cottony mildew develops on and around these foliar lesions. Stems, petioles, and tubers are also susceptible to late blight. Dry weather may interrupt the disease cycle, but if damp weather returns late blight will continue to progress.

In the following Spud Doctor video, Kiran Shetty, technical product lead for Syngenta, talks late blight and how research at the Syngenta Vero Beach Research Center tests management tools in the field under real conditions. Orondis® Opti fungicide, a combination of oxathiapiprolin and chlorothalonil, is one such tool. It protects the potatoes under heavy late blight pressure to help maximize marketable yields.
