James - I purchased some 1.oz (28g) Gnatrol OMRI selective biological larvicide for Fungus gnat control this year but have not used it because I didn't know how it would affect germinating seeds. Plus there was no label on the container and I can't find the instructions that came with it on how to measure and use it. But I have some. I just didn't want to kill my very young seedlings with Gnatrol.
