Mold?? On New Orchid

I've mentioned this before, but I have used marathon for scale with good results. Either spray or dab it on with a Qtip. One cupful in a quarter of water is plenty.

Interesting! Marathon appears to be imidacloprid.

I also heard of malathion - but haven't used that one yet. Pretty sure that is an effective treatment too.

Malathion*is an*organophosphate*insecticide*which acts as an*acetylcholinesterase inhibitor. In the*USSR, it was known as*carbophos, in*New Zealand*and*Australia*as*maldison*and in*South Africa*as*mercaptothion.

Imidacloprid*is a systemic*insecticide*that acts as an*insect*neurotoxin*and belongs to a class of chemicals called the*neonicotinoids*which act on the*central nervous system*of insects. The chemical works by interfering with the transmission of stimuli in the insect nervous system. Specifically, it causes a blockage of the*nicotinergic*neuronal pathway.
