This weekly update reports on the status of late blight in New York and the contiguous states and Canadian provinces.

New reports the week of 6/15-22:

On 6/19 late blight was reported on tomato in a community garden in north central Suffolk county, NY.  The gardeners were taking out all their tomato and potato plants.

On 6/17  late blight was confirmed on tomato from a home garden in New Haven county, CT.  The plants had been grown from seed by the gardener.

Outside our reporting area, a 6/21 find on potato in Michigan.

Previous reports (most recent first):

The week of 6/8-15 there were two additional late blight reports in Pennsylvania.  Both were on tomato transplants in home gardens.  One find was in Somerset Co. (south central PA), on a plant purchased at a local greenhouse.  The other was from Beaver Co. (near the Ohio border), unknown source.

Late blight was found in a greenhouse in northwestern Pennsylvania in mid-May.  It was being monitored and treated to prevent spread.
