I am in Central VA and I have this small garden where I am growing Cucumber, Tomatoes, Eggplants, Green Pepper, Zucchini and long Squash. It started with Zucchini, which got powdery mildew and it got zucchini completely so I pruned it and now Zucchini is almost gone and I am not much worried about it.
Last couple of weeks I am seeing Cucumber, Tomatoes and Long Squash also started getting brown spots on their leaves and and the leaves are turning brown completely. I googled many times and find it could be a fungus and suggestions were to use "milk" or "neem extract" as fungicide to control and eliminate the disease. But I am not seeing much improvement in Cucumber and Tomatoes and now I am very concerned about them. Please Help!!!
