Does anyone use AzaMax???

[Daintree]

Hi,
I was wondering if anyone is using AzaMax (organic insecticide/anit-feedant/IGR made by General Hydroponics) as pest control.  Some of my greenhouse plants get mealy bugs very easily (especially my coffee and citrus) and I usually use Neem/Py.  It works, but you have to keep on top of it ALL the time.
I bought some AzaMax this summer to try.  It came in little vials that you mix into a 1 pint "trigger style" spray bottle.  Of course, my hand cramped and my enthusiasm wore out long before the little bottle was emptied.  The results I saw were about the same as for the Neem/Py, but I don't feel like I gave it a fair shot. The organic nursery here in town uses it by the gallon, including as a soil drench, and swears by it.

I am tempted to buy the larger bottle of AzaMax, but it is outrageously expensive.
Does anybody have any experience with this product? 

Thanks!
Carolyn
