I mixed up the pyrethrin/rotenone insecticide and put it on my plants. On one hand, they stopped getting worse, so that's good. On the other hand, the stuff I put on them smelled strongly of mineral spirits/kerosene in its concentrated form. I accidentally got a few drops of the diluted mix on one of my plants and it killed the leaves that it got on. Why the hell do they mix that stuff with kerosene? The lady at the nursery said it wouldn't hurt my plants, shows what she knows.

I STILL don't know for sure what my problem is.
