Is this blight?
Roma tomatoes, live in Michigan, planted tomatoe in a standing planter with 50/50 compost and garden soil from home depot. Never planted in it before. Tried to use a mix of neem oils, garlic and hot pepper mix 1 spray so far. Can't see and overt pests. This plant is near another tomato plant that looks pretty ok and green beens.
Did have a 2 day period with low watering because I was on vacation.

|Welcome to NGA, @Jpbunka !
Tomatoes are subject to a number of different diseases... mine always are infected with something -- for years I assumed it was "blight," but I now believe it is either fusarium or verticillium wilt -- but they mostly grow faster than the disease can keep up with and provide me with lots of tomatoes, so I just don't worry about it all that much. I would suggest spraying your plants with Daconil and fertilizing them with a balanced fertilizer.

|Tomatoes really do have many fungal diseases. Just the nature of the plant. Also they easily pick up soil borne diseases. Cut off the bad leaves and throw them in the trash, not the compost. Also cut off any healthy leaves that are touching the soil.
Daconil is a very good product. Use it and it shows most tomato problems down and you end up getting a nice harvest.

|The Daconil is the best you can do but repeat EVERY 7-10 days and after a heavy rain.It's a constant fight, must stay on top of it.|

|Jpbunka I feel your pain. I have what looks like the same issue. I have come to believe it is Septoria leaf spot or possibly early blight. I have been pruning the affected leaves/branches and using Daconil once a week. I thought I had it contained but overnight it got loose again. Today was the day I usually spray them with Daconil. I look them over everyday and they looked fine yesterday. I started spraying everything in my container garden with Daconil when the fungus showed up on my tomatoes back in the end of May. So far it has not spread to any other plants but it is on all my tomatoes now. Good luck. |
