Curzate® Fungicide Helps You Battle Late Blight in Potatoes

New strains of late blight will require new solutions.

Late blight evolves. The devastating fungal disease even jumps between crops. Potato growers have to stay on top of the latest methods of control to stay ahead in this high-stakes battle.

There are 24 strains of late blight in North America so far. So, what can you do to keep late blight away?

Infected seed is usually the culprit

Carefully grade-out infected seed, cut and plant as soon as possible. Use a seed treatment that contains mancozeb, and do not over irrigate. Eliminate cull piles immediately.

Use DuPont™ Curzate®

During the growing season, watch for potential hot spots – low-lying areas or spots that receive more irrigation than others.

Dr. Ron Howard, a plant pathology research scientist with Alberta’s department of Agriculture and Rural Development, says that while there are many fungicides on the market for late blight prevention, DuPont™ Curzate® stands apart for late blight control because it has both preventative and post-infection properties.

“Curzate® will kill infections of late blight, provided they are not too advanced,” he notes. “It should be used only once or twice a season to minimize the risk of resistance development in the pathogen.” 

It is recommended to use Curzate® as a tank-mix with a registered Group M fungicide.
