Late Blight Alert

Dear Maine Vegetable and Small Fruit Growers,



Yesterday (May 29) we received notification from Dr. Meg McGrath (Plant Pathologist, Cornell University) that late blight was just identified in an early-planted potato field on Long Island. The farmer has destroyed the plants showing symptoms and has applied fungicides to protect the remainder of the plants.



On May 24, late blight was confirmed in an 8-acre potato field in Cookstown, NJ (Burlington County).



According to Dr Meg McGrath, the plants showed large brown classic late blight leaf spots; and a very few stems had large brown spots. She believes that the outbreak is due to contaminated seed. Two varieties with symptoms are Dark Red Norland and Superior(; seed from Maine.)



It is VERY important to scout your potato plantings and tomato plants for late blight symptoms, regardless of where seed was purchased.



Good resources with photos of symptoms and detailed discussions of how to manage late blight include:

If you suspect late blight, please take photos and contact Highmoor Farm (933-2100) or the Pest Management Office (581-3880). Please contact any of us with your questions.

Thanks for the update Tree! Hate the news, but appreciate the knowledge. This year I started quite a few of Johnny's blight resistant tomatoes as well as several heirloom varieties that got nailed last time blight came through. If I get hit again this year I'll post a run down of how the various cultivars did.

Oh, I'm very interested in the blight-resistant cultivars. Do let me know how they are, in general, also.
Like: do they taste good?
Thanks, Greg!
