With potato harvest winding down in many regions, growers have changed their focus to post-harvest tuber management and storage.

Phosphorous acid-based products can help control many post-harvest diseases if applied following best management practices.

To assist growers, Extension agents and consultants with the use of these products, Focus on Potato has produced a nine-minute Web seminar.

Steve Johnson, a professor and University of Maine Cooperative Extension crop specialist, narrates the presentation, according to a news release.

It will cover the differences among phosphorus-based compounds, which pathogens are controlled by the products, how to apply them to potatoes entering storage, and best practices to optimize disease control after harvest.

The presentation will be open access through Oct. 31.

Focus on Potato is a product of the non-profit Plant Management Network, a collaborative effort of the American Phytopathological Society, American Society of Agronomy and Crop Science Society of America.
