UMass Extension Landscape Message July 12, 2013

"Late blight (LB) was confirmed in Franklin County, MA on tomato July 11th, in Erie County, NY on tomato July 10th and on potato July 9th. Previous reports in (FL, WV, LA, TN, MD, KY, VA, NC, WI) have been confirmed as Phytophthora infestans strains US-23 and US-7. Track disease progress at USA BLIGHT. Tomato and potato growers should be spraying those crops with protectant, curative and locally systemic fungicides labeled for oomycetes to prevent disease establishment and spread.

If you suspect late blight, contact the UMass Extension Plant Diagnostic Lab at 413-545-3208.

Home gardeners should refer to our home garden late blight fact sheet at http://ag.umass.edu/fact-sheets/home-lawn-garden/late-blight-tomatoes-and-potatoes";
