My tomato plants have some sort of fungus taking over the leaves and stems. I've been removing the dead infected leaves, and today when I went out to tend to my plants, I was saddened to see that a large portion of my plants were infected! What is this, and is there a way that I can (organically) take care of this problem?
These tomatoes were supposed to be a source of food for my family this winter, so this is devastating.
Just a pic of the amount of leaves I had to prune off this morning:
