I have used Fertilome Fruit Tree Spray which is Neem oil and pyrethrins and it is very effective on aphids but not as good on mites. Permethrin in a strong soapy spray is better and malathion is even better but I rarely have to resort to it. I have sprayed for spider mites twice this year and used permethrin in a very soapy water mix and it was effective.
Raybo it seems that what is effective in the Azatrol is the insect growth regulator. Many IGRs can be used in con★★★★★★★★ with a poison like permethrin for a double whammy. If I had mites as bad as you, I think I would definitely use them both on all of my plants. I am considering using an IGR with poison to try to control whiteflies if they get as bad as last year.
