Tom Here is an example of why I say READ THE LABEL. In front of me I have a bottle of Bonide's Mancozeb Flowable with Zinc Front label says A broad spectrum fungicide for use on grapes, tomatoes, potatoes and other listed vegetables. For The control of anthracnose, boytrytis, blights, downey mildew and other listed diseases. In the store you say to yourself, H'mm it list tomatoes so may good for peppers. You buy, you bring home, and then read the stuck on label. Asparagus Corn Cucumbers Melons Onions Potatoes Summer squash Tomatoes and Grapes. (did not list flowers) H'mm, Peppers and Winter Squash not listed. Point, If it does not say ALL Vegetables on the outside label read the inside before applying. Tried a 25% solution on 1 plant, had phytotoxicity Oh well another $14 bottle of stuff to go to the once a year, hazzardous waste day at the recycling center. Byron
