Hi I have planted 6 tomato plants this year in a green house in new soil & using cow manure that has been lying fir 4 or 5 years. Their sister plants are in different soil in a green house and going fine. However mine have dry looking curled up leafs & very slow at bearing fruit. Any ideas on this ??

My E.H. House (from SHPC) is potato leaf, although the site doesn't say the leaf type. I'm about to email them and ask what it's supposed to be. It sounds like there are multiple versions of it going around. I'd guess the RL version is less likely to be authentic, considering there's one season less it would have to be grown to get that leaf type from a cross.

Well, I looked it up and found that a 70% neem oil product is labeled for early blight and other tomato leaf fungal diseases. But the product carries a warning regarding honey bees. You may want to note that when selecting a fungicide. Neem Oil Product Label I get a small amount of Early Blight most years and a greater amount of Septoria. The spots in the pictures look more like Septoria to me than Early Blight. I may be wrong on both accounts. However, I've found leaf trimming the affected foliage, and continually maximizing air flow by distancing plants and management pruning gives my plants an opportunity to outgrow most Early Blight and Septoria infestations. Still, I have to eliminate entire plants occasionally to safeguard the others. This year is the first time in several years that I've had to spray Daconil to arrest a severe Septoria infestation at one end of my garden (the least sunny end of the bed). And in this instance I trimmed off all the the lower and visibly infested leaves and only sprayed the foliage just above that point trying not to hit any fruit or flowers. I'll keep the neem oil thing in mind, but don't want to kill honey bees since I also have cukes and blackberries simultaneously and in same garden with tomatoes.

Pesticide injury is a possibility and a virus disease or ethylene gas injury can also be to blame. Usually look at the specific locations within the greenhouse to pinpoint the problem. How widespread is the damage? You mentioned 2 varieties. Do you have other varieties that are not affected? I heat with wood stoves and surprisingly the newer hybrids Torero and Rebelski are first varieties to exhibit intolerance to the stove gases. I would suggest taking a sample to your nearest university plant pathology department. Your county extension service can make the connections for you.
