Boston, MA USA “… Here’s an innocent victim who sent me her sad experience with the potato late blight:
“I am from upstate NY. I am an organic gardener with 63 heirloom tomato plants of 23 different varieties, all gone. I am in tears. I have 100% loss. I inspected every day and the blight took my plants in matter of hours.” …”
The Hack: any sign of blight on a tomato plant, bag it, seal it, DON’T compost it, and plant something else there next year – not potatoes either! Legumes (beans), cruciferous (cabbage, broccoli, etc), umbellifers (carrots, etc.).
