If I were you, i'd try that method. I believe it's rare and difficult to chance upon a mold/fungus killer that does not incur damange upon your plants.[b said:Quote[/b] (Bugweed @ Feb. 25 2006,9:32)]I just got Cleary's 3336WP from PetFlytrap (ever hear of these guys??) for molds and fungus, and have 0 mold this winter. TRY IT! It will kill many forms of mold and fungus. In the proper amounts, and they ARE premeasured, your plants will thrive while fungus and mold WILL NOT!!!!
