I have been advised that SM90 as a root drench is advisable for fungus gnats. Also, by the sounds of this post i saw, this guy seems confident that it will not kill the beneficials in the soil food web. But, as any organic gardener, i'm skeptical of bottled toxic junk. What d'yall organics guys think about this product? I will start searching organic remedies for this problem. Please see below explanation from the guy i referred to; the post of which i found on icmag.com0.:

theres not concern for it being hazardous expecially at 5% by volume. google MSDS Triethanolamine, that will fetch the Materials Saftey Data Sheet for this compound and its pretty benign, though all bets are off it you decided to drink it.
as far as its function id say that it probably has to do with Ph stabilization of some kind judging from the 3 exposed OH groups on the ethanol groups, which will freely donate a hydrogen atom. im willing to bet that it was added because one or more of the other ingredanse is more basic and the TEA(triethanolamine) is used to counter act bringing the Ph back ot neutral. why not use some other chemical to stabilize the Ph other then TEA? well because its an amine that means that there is a nitrogen present and in this case the Nitrogen is located directly in the center with the three ethanol groups shooting out from it. nitrogen is very happy with three single bonds and wants to remaine that way. so in commercial application that means that the compound, wont degrade creating unwanted by products and possiable unwanted interactions (ie killing your plant) and #2 its stable and inert. it wont interact because all the atoms present are happy and want to remaine that way.
