Barb from Pontiac, Illinois writes
Can I spray daconil on my orchids, cattleya has fungicide on it, how much to gallon of water, please ?
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.
We would recommend contacting a local orchid specialist/nursery or the Master Gardener with your County Extension Office for their recommendations.
