Answer: Based on your description I am not certain what is affecting your plants although it sounds as though you may have some insect and disease problems both. I would strongly suggest you work with your local county extension to obtain a specific diagnosis of the problem(s) before you continue spraying. Once you know the exact culprit(s) they will be able to help you determine how best to treat it and with what. If a chemical control is needed they can tell you how and when to apply it for the best results, also then be sure to read and carefully follow all of the label instructions.
