Sooty mold
Hi, all,
I currently have a number of my planst that have what looks like sooty black mold on the leaves. It's not selective as to kind of orchids; it's on different kinds. I have tried to clean the leaves by hand using cotton balls and alcohol. The mold 'washes' off without too much effort. It occures on the top and bottom sides of the leaves. Can anyone recommend a deterent of some kind? (spray?) Chris Savas (remove not from the address to respond directly) |

Sooty mold
Often, such a "sooty mold" is a precursor to insect problems (I'll be
honest, after than nice French viognier we had with dinner, I don't recall if it's scale or mealies), but soapy water is useful to wash it off.

Can anyone recommend a deterent of some kind? (spray?) Sooty mold is a fungus that grows on honeydew, a sugary excretion of sucking insects and mites. Some of the most common are aphids, scale, whitefly, mealybugs, leafhoppers and spider mites. If you deal with that problem the mold will go away or it can be washed off with a mild soap or detergent. Often ants will be tending the insects and harvesting the honeydew so they need to be controlled also. -- 09=ix |
