Am 58 was used to having a good greenhouse crop of tomatoes .the last 3 years I have had in 2 different greenhouses brown stem tomato blight spreading to the leaves and fruit. Have cleaned the greenhouses disposed of the soil and put in new horse manure with a peat overlay well rotted and moist. good ventilation kept window and doors open all summer.watered early morn and late evening. still stem rot leaves crinkled brown and some fruit discoloured. help me please am at my wits end.
It's hard to say without seeing them - but at a guess I'd say they've been overwatered. Even in a greenhouse they shouldn't need watering twice a day - if the soil is permanently damp and the greenhouse is warm you've got the perfect conditions for blight to develop
Probably too late this year, but next year let the soil dry out until the leaves loose a little turgidity then water well.

peter, Dove's right. That's too much water, but it's not going to cause a fungal problem if what you actually have is a fungal problem. It's hard to identify the problem without seeing it. Can you post photos?
The aspirin-as-a-treatment-for-fungal-problems theory has been around for a few years. In short, it's based on the notion that one of the constituent parts of aspirin triggers a tomato plant's inbuilt defences against fungal disease. I've never tried it, the few people I know who did try it said it had no noticeable effect. Give it a try, see what happens.
Purchase regular strength aspirin. The brand does not matter; purchase the cheapest brand that is available.
Mix together one aspirin with one gallon of water. Combine the ingredients well, so that the aspirin is distributed evenly throughout the liquid.
Add a dash of mild liquid soap to the mixture. This is used as a way to help the aspirin water stick better to the tomato plants. Once the soap is added, attach a spray nozzle to the gallon jug and it is ready to use.
Spray the tomatoes when you first set them in the ground. Aspirin sprayed directly on seeds improves germination, on plants it stimulates the growing process. There is no need to soak the area. A light and gentle spray will suffice.
Continue to spray the aspirin mixture on the tomato plants every 2 to 3 weeks. You are going to notice that the plants stay healthier and attract fewer insects.

Would spraying with a aspirin mix as a preventative measure stop blight ??

thank you itlophile
here is the mix anyway
Water your plants with an aspirin?! Salicylic acid, in aspirin, triggers a defense response in tomatoes and other plants as well! Adapted from eHow: The main benefit of aspirin in planting involves aspirin’s ability to fend off potential plant diseases.
