I noticed that on the top of one of my vanda's this clear sticky liquid seems to be forming. I read that the presence of a honey dew like substance can be an indicator of scale insects, which secrete such a substance. I first notice its presence about a week ago. I have look been monitoring very closely with an magnifying glass but see no other signs of an infestation. Such as web like material on the underside of the leaves.
I am wondering if I should treat it with a Fungicide. I have uploaded a pic in my galley.
