From Meg McGrath, Long Island Horticultural Research & Extension Center, mtm3@cornell.edu:
Since the period lasting several years when late blight was common in the region, starting with the late blight pandemic of 2009, occurrence of this destructive disease has been steadily declining. It was reported in only two counties in the Northeast in 2020 and in 2021, and none in 2022. This decline likely reflects growers having increased knowledge about the disease and implementing good management programs. A new late blight webpage has a table with counties by state and state regions where late blight was reported in the Northeast since 2017 at the USABlight website plus U.S. maps with all occurrences highlighted by county by year since 2011.
