Brown lesions on various vegetables
My plants are being afflicted by something, and I have no idea what it is. I have done some web research, including searching gardenweb, but the problem is that there seem to be many different infections that cause similar symptoms, and I can't get a straight answer on which this might be, and more importantly, what to do about it.
The problem is surprisingly broad-spectrum, and visions of losing large swaths of my garden are running through my head. The symptoms are as follows: yellow spots on leaves turn into dry, brown lesions, that eventually result in the entire leaf turning brown and wilting. The problem seems to have started on the lower leaves of the tomatoes. The really disturbing thing (to me) is that, not only were tomatoes affected, but so were a few kohlrabi that were in contact with them. And so were some beans, summer squash, broccoli, and potatoes, that were not even in contact with the tomatoes. As I think about it, IÃ¢ÂÂm starting to wonder if this is what killed all my early peas (and seems to be in the process of killing my 2nd batch of peas now). ItÃ¢ÂÂs possible that this isnÃ¢ÂÂt the same thing for every plant, but you be the judge. I've posted the pictures in a gallery over on my domain, which can be accessed at this URL:
Thanks for any help you can offer.
