From Meg McGrath, Long Island Horticultural Research & Extension Center.
“Concern that rainy weather this spring would provide favorable conditions for late blight has unfortunately turned to reality. This devastating disease has just been confirmed on on five different farms on the South Fork of Long Island, and on potatoes in Virginia and Delaware. Researchers involved with a national project on this disease are studying the outbreaks. Greater understanding of the source of the pathogen responsible for these outbreaks will lead to better prediction and management in the future. Reports and samples are needed from gardeners as well as farmers who have late blight.”
