A fellow forum gardener introduced me to AzaMax --

Used a lot with hydroponics but not limited to hydroponics. Food grade ingredients and good for use on food crops. Works well on spider mites on my lemon tree too. In the fall, I hose down all containerized plants that I want to bring indoors and then spray thoroughly with AzaMax. And I avoid bringing indoors aphid magnets like peppers or Abutilon. I can spray as needed over the winter/early spring indoors with no problems.
