I live in Chicago area. Last year we had a cool year. I had an eruption of some sort of virus that wiped out almost all of my 40 plants. It was a disaster. The plants were looking to be very productive and then they all dies. It stated out with spots on the lower leaves and progressed higher into the plant and to the stems. The stems turned a yellowish color and became limp. Even some of the ripening tomatoes saw some effect. The progress was rapid. Eventually almost the entire plant shriveled up and I removed them. I have three pictures that show the disease. One shows the leaf spots. Another shows more leafs as well as stems in the background which have spots and can be seen to be turning a pale green to yellow color.
Do any of you recognize what this might be? I'm trying to diagnose it so I can hopefully mitigate the consequences. I only have two locations, about 20 ft. by 20 ft, in a suburban location where I can plant. Crop rotation is not much of an option. I either plant or don't plant and I prefer to plant. I have not turned the soil over at the end of the year for the past two years and I understand now that perhaps that is something that should be done to keep viruses from over wintering.
If any of you could recognize what my plants were afflicted with and what actions I need to take to avoid a recurrence, I would most appreciate it if you could share what you can with me.
