Jul 28, 2015Indiana reports late blight in potato 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.
See “Potato late blight found in Michigan in 2015” published July 24, 2015, for an update on scouting, treatment recommendations and products.
