Best organic fungicide
Comments (5)The best overall organic fungicide for regular use is sulphur. #2 is probably Serenade and #3 is Saf-T-Side oil I would say. As ltilton mentions, you need to first figure out what disease you have since there is no one size fits all spray. For grapes you often need to use copper since downy mildew and black rot are not controlled at all by sulphur, oil or serenade. Copper is the best dormant spray but most plant leaves are phytotoxic to copper; grapes are one of the few exceptions. Scott...See MoreOrganic Fungicide
Comments (6)Thanks to everyone for the responses. Nandina, I've been doing some research on diseases of asters, including aster yellows, but nothing seems to fit exactly. My best guess is either aster yellows or botrytis blight. I'm leaning toward botrytis blight, since the plants went downhill so quickly and botrytis likes wet conditions.

Comments (11)Well said Ami, b/c I was going to attempt to answer the question by linking elsewhere but I've asked several times if linking to other message site threads to help answer questions could be done without someone being banned here, and have never received a definite answer, How does one distinguish between an "ad" and another message site or to even a Google search that would bring up links to several disease sites. I did check the Pest and Disease Forum here last night and I can't find any of the links that many of us entered that would help folks make diagnoses for various diseases and pests. Tamara, could you please help clarify for us? It would be greatly appreciated. Thanks, Carolyn, who should have also put this post in the correct thread which was the one at the top asking a huge question about pests and diseases, but it goes here as well in terms of organic fungal products, in a general sense.
