Willie Kirk, and Mary Hausbeck, Michigan State University Extension, Department of Plant Pathology -

Still no reports of late blight on Michigan potatoes and tomatoes, but there is a 24c label for Bravo ZN for long-term potato storage crops.

Late blight has been confirmed on potatoes and tomatoes in New York, Virginia and Florida within the last seven days. The reports were confirmed on the new potato and tomato late blight research project website at http://usablight.org where reports are updated as they occur throughout the country. There are still no reports of late blight in the field in Michigan on either potatoes or tomatoes.

Michigan has a 24c label in place for Bravo ZN that allows a maximum of 30.5 pints per A per season to be applied to long-term potato storage crops.
