Locally, a commercial grower was having, for the first time, unacceptable
losses from fungal infection after deflasking orchid seedlings into
community pots. Finally, he brought in the government agricultural extension
experts who diagnose it as the gnats, with the fungi entering from root
damage. So, he sprayed with insecticide rather than fungicide and his
problem disappeared. So, which is primary and which secondary?
Cordially, Phil
