Blight is identified by brown or black spots and yellowing leaves.

Next, you must purchase a fungicide that will halt the spread of the blight. Organic growers choose a natural, copper solution, though many other products are on the market. Visit your local garden center, nursery or hardware store to find a fungicide which targets blight on tomatoes. Generally, you will need to dilute the product in water and use a spray bottle to apply it thoroughly to the entire plant. Spray until the plant's leaves are dripping with the solution. Though you should always read the directions carefully, you will probably be instructed to apply it once a week and after rains.
After you begin spray-treating your tomato plants, continue to check for the spread of blight and remove damaged leaves. Though this process is tedious, it is the only way of minimizing the damage to your plants and encouraging as much tomato-production as possible.

- Tomato blight, if left untreated, can completely devastate your crop.
- You must remove all of the damaged leaves to help stop the spread.
- Blight remains in the ground, so you'll have to plant your tomatoes somewhere else next year.

I have lived in Western PA all my life (now at age 54) and have had a garden much of my adult life. I never heard of this blight before, this is the first year I have seen it and have fallen victom to it. My question is the last few years we have had strange bugs and now strange diseases to our plants why all of a sudden is Western PA having problems? I believe this is a man made problems!!

We started our plants from seed this year but still got blight in on section of our garden. The spores are airborne and you can get them from neighboring gardens so keep a very close watch on your plants and act quickly if you see anything. I have heard of folks going away for a few days and coming back to find most of their tomatoes ruined.

Bought plants at Lowes in Milford, now have blight. Thought it was going great until I checked recentlt. Question...any potential harm to me...breathing in these spores? I did not know this was fungus based disease until after being out there all day with my face in these plants clipping leaves and bad branches.
