Phyton 27 & Dends?
All,
As far as I know, copper is not good when mixed with Dendrobiums (leaf drop). Phyton 27 is copper based. Yet, I know several people who say it's okay to use. Opinions, please? Diana |

1) Copper is a very effective herbicide, sometimes used to kill aquatic
plant life. 2) Copper is known to be toxic to several orchids and many other plants.

Actually Physan 27 is one of the few products out there that is labeled for

Never did it myself, but I have also seen Dens completely defoliated by Kocide, another copper fungicide. The fellow grower who made that error tells me that most of the plants survived, but the old growth was ugly for a LONG time. The folks at Phyton 27 claim to have somehow "buffered" the copper ... -- Kenni Judd Juno Beach Orchids http://www.jborchids.com "Diana Kulaga" wrote in message ink.net...
