This sucks, after thinking I was doing everything right with trying to solarize my garden over with the extra warm winter, and spraying my plants with bonide fruit & veggie spray, looks like the late blight is here on my tomato plants again (though I have lovely tomatoes!). After uncovering my garden I also put a thick new layer of dirt on top of the old and was trying to be careful not to disturb the old dirt.
So what can I do to try to knock this out when I tear my plants out this fall or early in the spring? I hear broken egg shells sprinkled in the garden help, and read someplace a spraying on the dirt of 2 Tbs bleach + 2 Tbs baby shampoo in a gallon of water works on the soil. Any other advice?
