Where can i buy auxin?

Question

I am trying to find some auxin (indole-3-acetic acid) in a paste form to use on some plants. Does anybody know where I can get this?

Answer 1

You really sure you want IAA and not IBA or NAA? (the last two are a lot more stable).

I've gotten IAA from Sigma, and just made my own paste of the required concentration, with either lanolin or KY jelly (which appears not to be phytotoxic).  I've also used agarose blocks for IAA demonstrations.

IBA and NAA are generally found in dilute forms as "rooting powder" or "rooting liquid", and are much easier to come by -- just about any greenhouse supplier will carry these preparations.
