This year I grew a few varieties that are supposed to have some resistance to late blight:
Mountain Merit
Iron Lady
Early Sue
Magic Trick
Sky Komish
There have been cases of late blight reported in MA. So far, all varieties are healthy. Iron lady doesn't seem to be producing blossoms (at all).
I've been spraying the plants with Fung-onil which lists "late blight fruit rot" as a disease it is supposed to control. A little confusing because late blight really attacks the whole plant (leaves, stems and fruit).
So far so good....
