I think Arbor-jet also has the Azadirachtin based treatment.

That tre-age is expensive, $600 for a liter. How much of that stuff would you use for a preventative treatment with 18" DBH ash ?

For a 18" DBH you would use 80ml of Tre-age with equal amount of water. Around here its about $500 a liter and you save if you buy a case.
