I was disappointed to hear that late blight has been spotted in Massachusetts (links below) this week. On Tuesday, it was found on tomatoes in a field in Hadley MA (Hampshire County, western MA). Tests are being done to figure out where it came from.
Its also been found this year in a garden in Maine, and on commercial potatoes in Wisconsin.
I have been looking at tomatoes and potatoes in our plots and have yet to see any late blight.
