Hi again. I usually just apply the fungicides on the wound directly. If it's sprayed on I just follow the directions on the container, being sure that the temp. isn't above 78degrees. The soap drench is alot less technical... a couple squeezes of the bottle into a bucket of water(which is about room temp). Then I leach them within a couple days. I usually use Ivory/Palmalive soap, they seem be the safest.
I don't like using the copper spray(Bordo) as well since it leaves such an ugly blue residue, but this is probably one of the strongest fungicides out there that is safe to use. I have also used Safer's Defender on outdoor roses, etc. to great success, haven't tried it on orchids yet though.
In the past we had so many bugs in the bark of our plants(we had moved them outdoors for the summer where they picked up everything) so we had to resort to using Diazonan! The orchids didn't flitch, but they smelled like death warmed over.
Not a critter moved for months afterwords.
