    Default Captan dosage for Orchids

    I have a bottle of Captan wettable powder by Bonide. The mixing instructions do not list orchids but various fruits, vegetables, trees, and flowering plants. Note that there are no listings for tropicals or house plants.

    Would the mixing instructions for roses be close enough for orchids or is there another key plant I can use as an indicator?

    (I have Physan and Phyton; I am asking about Captan)

    Yes, the rose recommendation is the standard fallback dose for most chemicals if orchids are not listed.

    FWIW, the Captan 50WP I have seen calls for 5g/gal.
