If yes, amount per gallon?
There are a lot of articles that say that the active ingredient in Garden Tech Daconil Fungicide Concentrate, Chlorothalonil, is safe to be used on orchids. Since the product itself is not labeled for them, the only rate we can give is for ornamentals which is 2 1/4 tsp - 3 tbs per gallon. You may want to double check with someone more familiar with orchids though.
