    Question What to look for in a fungicide?

    I hate to pay inflated shipping charges so I am looking for a fungicide from local suppliers. Local hydroponic stores, home inprovement stores, and garden centers all carry a wide variety of fungigides but none that I have ever heard of being used on orchids.

    What should I be looking for in one? I assume I should get a systemic one but what else?

    What kind do you use and why?

    Do you use it regulary as a preventative or only as needed?

    Thanks,
    Travis

    Well I'm not really one to mess about with cottonballs, q-tips, voodoo recipes and hoping for the best. And I'm not afraid of using chemicals as directed either. Sure I'll use a quick dab of cinnamon occasionally during routine grooming but if I have a problem I want to use something I know will work. Or at least I want the peace of mind of knowing I did as much as I could... So after doing some research into what the professionals use/recommend I settled on buying Phyton-27 and found it at a local nursery. It's a systemic fungicide and bactericide product. No, it's not cheap. A 2 oz bottle cost $15 but I usually treat only on an 'as needed' basis. The only exception being that I usually do treat new plants received in the mail, particularly if they've been in transit 2 or more days. Anyway, I draw up what I need with a syringe. Those clear, marked medication cups work well too. 2.5ml in 25oz water is usually ample for what I'm treating. I have no idea how well it stores once diluted so I promptly use up whatever I make. But I'm definitely satisfied with it.

    We spray every few months as a preventative with an alternating series of things: Phyton-27, Daconil, RD-20. If you're looking for something readily available locally, I'd recommend the Phyton which is systemic; the Daconil is not systemic but works very well too as long as you don't mind the whitish residue on the leaves, and it's available pretty much anywhere. We use these for the same reason Maire already stated: because if we're going to take the time to spray, we need to know that the stuff we're using is actually effective and really works. If for some reason you can't find any of the above locally, most brands of fungicides will do the trick (I say "most" because of the discussion that came out of orchid_fan's earlier Neem question); just make sure you choose one that's labelled for use with ornamentals--preferably for orchids in particular (!!) Finally, many growers who don't want to use poison use cinnamon as a fungicide. Do a forum search on the word cinnamon and you'll come up with several relevant threads.

    Systemic means that it enters the 'bloodstream' of the plant and effects the entire plant, not just the area where the spray (fungicide, pesticide, etc...), made contact with the plant. When speaking of pesticides a pest will die by eating any part of a plant treated with a systemic instead of having to spray the actual pest in question and make contact with it. I think that how long the effects last can vary but usually about 2 weeks I think. All of what I just wrote is based off what I have always known and could be wrong.

    Not wrong at all, Travis. Two weeks for a systemic is a pretty certain bet; many times it'll stay in the system for a lot longer.
