I got a notice today that late blight appears to be in our area. Its within 200 miles away – in Franklin County, western MA. **#@&!!! *^&&%%*!!
At our community garden, we had such a bad experience with late blight last year that we contracted to have late blight resistant tomato seedlings grown for us by a local grower this spring. (I wish I could find the newspaper article link – another **%^$@!)
Our garden is supplying a few organic pest controls to all gardeners. Now that late blight is in the area, our recommendation is to spray all tomatoes and potatoes before rains and at least every 7 days alternating between Oxidate (Johnny’s) and copper fungicide.
