Lagrange County, Indiana, reports late blight in potato and tomato fields.

A potato field and tomato field in Lagrange County, Indiana, have been reported with late blight over the weekend (July 25-26, 2015). The tomato field has now been treated. The genotype is US23 - A1 mating type and Ridomil sensitive. This information is important to Michigan growers as some have fields on both sides of the state/county lines.
