I still have my jar of Rotenone back from 1970.

Slightly different chemical.

I have kept it clean
by putting a little of the powder onto paper, using that on the
cuttings, then discarding the paper. The directions say not to dip
cutting directly into the jar (makes sense).

Spreads disease. Better just to waste 1/2 tsp than a tray
of the cuttings you thought were worth the effort to root.

I have tested the
effectiveness using coleus cuttings and it is still good.

Coleus is already fast. It rooted faster with Rootone?


I've been using same bottle for maybe 30 years. I would anticipate that
the naphthalene acetic acid would be very stable but thiram would slowly
degrade particularly if wet:

My stuff still appears to work. I just finished rooting a dozen
gardenias which to me has never been easy.
