Tomatoes - is it blight?

Asked September 17, 2014, 4:53 PM EDT

Every year my tomatoes plants lose their leaves, usually after they have set fruit. I end up with a fairly decent crop, but the plants have no leaves. They lose the older leaves first. Does this sound like early blight? Is there an organic cure besides rotating crops? I don't have much room. Thanks

Thank you for contacting MSUE's Ask an Expert

There are several tomato fungal diseases running rampant this year in our area, due to the extremely high rain levels, heavy dews and high humidity. It sounds like you are indeed seeing early tomato blight on your plants. The website below will help you ascertain if what you are seeing is early blight or one of the other diseases and give you some informationn about helping to control it in future years.

It is good that your fruit is still healthy, but you may want to consider relocating your plants in another part of your garden next year.

Below is information on LATE blight of tomatoes (as well as potatoes) that you will want to watch for.
