What is the strongest systemic pesticide available?

So I want them all dead and don’t care how I do it since it’s not edibles or smokable getting sprayed.

Orthene (acephate) is systemic and readily available. The stink of the stuff is enough to kill. LOL

Cygon (dimethoate) is another systemic insecticide/miticide. Not as widely available.

If all those webs in the grass and bushes are spider mites, I am doomed. I just found the start of an infestation on a plant 3 weeks away from chop, and had to spray my Haze Hybrids for te first time
