This week, late blight was confirmed in gardens in New York’s Chenango and Livingston Counties.
If you’d like to stay up to date on where late blight has been detected, check out the new Late Blight Alert blog. Abby Seaman, WNY Vegetable IPM Educator with the New York State Integrated Pest Management Program, updates the blog weekly, reporting if and where late blight has been confirmed in New York and contiguous states and provinces. She also includes links to other late blight resources, including instructions for what to do if you think you might have it in your garden or on your farm.
Late blight diagnosis can be difficult for those of us who aren’t trained plant pathologists. To help, Meg McGrath, plant pathologist at the Long Island Horticultural Research and Extension Center, has developed a Late blight ‘imitators’ page that compares late blight with several other common diseases that might be mistaken for it.
“There are several diseases and disorders with symptoms that could be mistaken for late blight,” writes McGrath. “But unless you are able to conclude with great certainty that your plants do have one of the other maladies, get help by submitting a sample to a diagnostic clinic.”
