Phal Orchid Rot Starting from the roots - lost 8 plants and counting HELP

[becky77]

I am having a serious problem with my collection of Phalaenopsis Orchids. They have what appears to be a type of Orchid Rot that starts with the roots and moves to the core of the plant after which the leaves start to turn go & the plant then dies. I am at a loss to pin point this problem, as I cannot find any classic disease signs before it’s too late. I am treating the plants with a topical fungacide and bactericide but it seems to be ineffective. It spread like wildfire killing 6 plants in the space of a week before I separated the plants to their own discrete areas and since then another 2 have died. I have ruled out the basics (water humidity temp etc) changed the mix sterilized everything but so far nothing seems to slow this pest down. Any advice is appreciated, as I am desperate so save at least one or two. Photos will be posted

I think this is a clear case for buying some Phyton 27 (don't confuse it with Physan 20, which is not systemic). Phyton 27 is expensive, I bought mine at Hummert Int. It was $53 for 8 oz. I see they now have a 2 oz bottle for about $20, but they have a minimum order of $50, so you can look else where or buy the larger size or add in something else.

Phyton 27 is systemic for both fungal and bacterial diseases. It is the best thing out there that I know of and it works. In your case it will be worth the cost.
