Spider Mites on Poplar: Charcoal Dust Look, Weak Miticides

Charcoal-dust look on poplar leaves (won't wipe off), green underside, red bumps on branches that bleed red, tiny greenish spider underneath = spider mites. Regular insecticides don't work. Need true miticide. Homeowner options: dicofol (Kelthane, hard to find), acephate, dimethoate, chlorpyrifos, diazinon, disulfoton, malathion—all weak miticides. Check label for "miticide."
