I have got a severe problem with some of my tomatoe plants. I have two rows of tomatoes. The first row, which has a black spotted and yellow leaves that fall off and is contagious to all other plants in that row, I have planted in ground that has acorns that fall in it (the row sets under an oak tree, but it gets lots of morning and midday sun), and the other row, which is about 10 feet over looks good. Now, the first row is planted with Arkansas Traveler which is not a hybrid, and the other row is planted with Early Girl, which is a hybrid. However, these leaves on the Arkansas Traveler are yellowing and falling off with black spots on them and my plants will soon be gone if I don't find out what is happening. We have had lots of good rain also. Does anyone know what I can do, or what is going on??? Help!!!!
