The active pesticidal ingredient in Azatrol and Azamax is 1.2% Azadirachtin.
Azadiractin is extracted from neem oil making it more potent than straight neem oil, also it is more water soluble for easier spraying and drenching.
There are also products containing "Clarified hydrophobic extract of neem oil" which contains less Azadirachtin.

Summary
These two active ingredients are derived from the oil found in neem tree seeds. Humans have used this naturally-occurring oil for millennia for medicinal, cosmetic, and pesticidal purposes. When used in pesticide products, both azadirachtin and clarified hydrophobic extract of neem oil can be applied to many food and non-food crops indoors and outdoors to control certain insects and related pests.

Azadirachtin and Clarified Hydrophobic Extract of Neem Oil are derived from the natural oil found in seeds of the neem tree, Azadirachta indica A.Juss, which is native to arid regions of India. The ability of the oil to repel pests has been known for thousands of years; the oil also has been used on skin and medicinally. When the natural neem oil is removed from the seeds and treated with alcohol, virtually all of the azadirachtin and related substances separate from the oil itself. The remaining oil - without the azadirachtin - is called Clarified Hydrophobic Extract of Neem Oil. Azadirachtin acts in the following ways: It deters certain insects, such as locusts, from feeding and it interferes with the normal life cycle of insects, including feeding, molting, mating, and egg laying.

I never have, but I know people who have watered it in as per the label rates, and none have had problems with burning the plants. I have not heard of anyone eradicating their mite infestation by watering in neem products
Also remember to rotate sprays, you just can't rely on one thing.
And spray often.
And spray them when they're young.:rastasmoke:
KaptainKron Reviewed by KaptainKron on . Azatrol Spider Mites Killer? Hi everybody. I had a nasty battle with SM that I think I finally won. But now I found out that product called Azatrol will kill them if you will mix it with water and water your plants. SM than will drink the plant juce that was poisoned and will die. Do you think it's going to work? If it is, for next time I rather do that than spraying plants or using booms. It sounds like Azatrol will do less damage to the plants if you'll use it this way, because spraying fucks up plants pretty good. Rating: 5
