Every year we wash out the greenhouse with Jeyes and change the soil completely for well rested replacement.
We grow our tomatoes from seed, give them daily attention and usually have a bumper crop.
This year everything proceeded as normal except now the leaves have lost their luster and developed yellow patches ALL OVER and one plant has shrivelled up and turned brown and is like powder if you touch it. It would appear to be fungal.
Can anyone identify this problem and suggest a crop-saving strategy - PLEASE??!?!?! - RUTINELI

My friend had the same thing happen to his tomatoes he tried separating the diseased ones but ended up burning the lot. Also one of his neighbours has the same problem , so it must be an airborn virus . We have tomatoes in the garden with no problems , it only seems to attack the ones in the greenhouse. Don't think there is a cure . Hope that helps . Good luck .

Sounds like tomoato blight to me, except normally it's outdoor tomatoes that are affected by this first - mine have it this year, I suspect because of all the rain we've had. Obviously it doesn't rain in the greenhouse but I think the spores are air-born.

hi, have the same problem. leaves going black and dying off, tomato's turning black. beleive it was caused by lack of ventilation in the greenhouse due to the damp humid weather. I cut the dead leaves away and trimmed lots of other leaves to leave just new growth from the main stem, left the door open all day and a roof vent to cause a flow of air, and sprayed a fan water jet from a hose quite fiercly all over the plants. looking better now, all growing green, but we need some long sunshine periods to spur them on.

Thanks for that Alf. I have had the vent open and the door a crack but the cutting and spraying is a good idea. Normally get about 80 to 90 lbs a year but things are going to go on ration I think.. Funny thing is the cucumbers are not affected and are roaring away. Cheers anyway to all. Rutineli
