I have had a pest decimating my collection of orchids. I tried repotting because I thought it may have been a bad batch of coconut husk chips. I have sprayed acephate and malation, azadiractin, and now Talstar (bifenthrin…a synthetic pyrethroid) multiple times over the last 9 months and still my leaves brown from the bottom and die. Also the color of the leaves is lighter than it should be. I have dealt with other pests and never had a problem. The broad mites are only seen under 40 x magnifications. They are transparent clear to brown and look like a white dotting on the underside of the leaves. There seems to be some leaf cell collapse in brachys. I am at my wits end. Any suggestions? I’ll post photos soon. HELP!
