Is tomato blight limited to tomatoes or can other plants become infected with it?

I bought a mixed herb pot from a garden shop that had a tomato plant as well. The tomato plant is infected with tomato blight and it seems like it has spread to the basil and the dill in the pot. My rose bush nearby and my rhubarb plant also have yellowing leaves with dark spots on them as well.





Here is what the tomato blight looks like

It can spread. I would spray with a fungicide to save my roses and rhubarb. The rest of the plants should go. In late fall and again in early spring spray your soil with a mixture of 2tbsp of bleach and 2tbsp of baby shampoo in a gallon of water. This covers 100 sq ft.


Another option is to soalize the garden area, you can do that by putting black plastic down and leaving it all winter. The soil will be sterile in the spring, kill weed seeds, fungus etc.
Reply:the perfect answer!!!!these two things work perfect for me...When you are ready to plant tomatoes,,lay down rolled black plastic, it works like a blanket, no weed can come up or blight for that matter, just cut out holes where you want to plant and poke small hole for drainage, when tomatoeplants get larger you can also trim off bottom leaves....The black plastic is also great when growing cukes!!!good luck
