A friend has lots of orchids and a scale infestation. He has tried many mild treatments and is now preparing to use Cygon...any suggestions? Has anyone used this chemical? He hates to use chemicals this strong but if he doesn't he's going to lose his orchids it seems.
scale on orchids
I found this letter that refers to using cygon for scales on orchids http://www.notsogreenthumb.org/q_and_a/1998/98-oct-scale.htm
Many thanks! I will pass it along.
