KathySEFL Delray Beach, FL (Zone 10a) October 30, 2009 10:14 AM	Hi, I am relatively new to Daves Garden, and have been posting on the self contained garden forum. I started my first veggie garden in a long time. I am in South Florida. I planted "Bandit" sweet corn on September 29. I interplanted Kentucky Wonder pole beans October 4th when the corn was about 4 inches high. Perhaps I should have waited another week, for my beans are outgrowing my corn at this point. I think my corn has corn blight, but am not positive. Some lower leaves are browning, and newer leaves have brown elongated spots. Thinking I had an insect pest, I sprayed last week, one evening, with insecticidal soap. I still think I have a bug, something tiny but perhaps blight as well. It has been very warm and humid here--in the mid to high 70's at night, and near 90 F during the day. Does anyone have a control, organic preferable, that they recommend? I have posted this on the organic gardening forum as well I am including a picture of the corn leaf with symptoms when it first appeared last week. View Larger

Serenade Garden Disease Control is a broad spectrum organic approved fungicide, but I don't know if it will work on corn blight or rust.
