|I had a different question but when i was going through the Q&A section I read a post about early blight! Well that lead me to this question: My cucmbers, beans and tomatoes, all beside each other have little reddish brown spots and holes in them! Thougth it was bugs but maybe early blight? Is this something I need to worry about? I try not to use sevin unless absolutely necessary. I even sacrifice some of my crop to the bugs cuz I figure there will be plenty. Please help and thanks for such a nice program!|

There aren't many diseases that the cucumber, bean and tomato share (they're all in different plant families), and none that fit your description. Warm, humid/wet weather is favorable for the growth of fungal and bacterial diseases, and it's possible that your plants are suffering from some kind of infection. Late blight, caused by a fungi (Alternaria solani) doesn't infect beans or cukes. Bacterial spot (caused by Xanthomonas vesicatoria) does cause leaf spots on cukes and tomatoes, but doesn't affect beans. Since you describe the spots as the same on all the plants, I'll bet they're the cause of some pest insect (your first intuition!). Look for flea beetles, tiny, shiny black specks that disappear as you approach (they jump like fleas, hence their name). They'll eat most anything, and are most happy in dry, hot weather. They're not easy to control, but since their damage is mostly cosmetic, control is seldom necessary. If they start to defoliate your plants, that's cause for action. So keep sharing, and enjoy the harvest!
