Good luck with this project Dar, and when you get plants ready for sale that are septoria tolerant, I'll be first in line to buy some
. Last year it stripped every single plant bare. This year has been drier than usual, but one of my Legend plants is really getting hit hard, even with the preventative spraying I began a while back. It is not only on the leaves, but the stems are becoming covered with the black specks. I even found one green tomato with teeny little specks on it, and I've never seen that before. Thankfully so far it is just one plant, but that doesn't mean the others in the area won't start as well.
Please keep us posted!
