Watch our video to learn how preventive applications of DuPont™ Zorvec™ technology as a potato late blight treatment help stop the spread of the disease by penetrating leaves to prevent oomycete sporulation.

 The critical time for potato development is typically the period from 20 days after emergence to 50 days after emergence (roughly 40 to 70 days after planting). This timeframe has the biggest impact on harvest quality and yield size.

The two key stages of potato phenology – or development – occur during this time: rapid vegetative growth and tuber initiation. Research trials show Zorvec™ technology is most effective when applied throughout these stages according to label directions, before symptoms of potato late blight appear. Preventive use protects potato crops during this crucial period when the disease has the greatest negative effect on crop yield.

In field trials, Zorvec™ technology has proven highly effective at controlling late blight of potatoes at lower use rates than competitive products, with no cross-resistance to other fungicides.

As a potato late blight treatment, DuPont™ Zorvec™ disease control technology delivers an unmatched combination of consistency and longer-lasting control to help you realize a more successful potato harvest.
