How many ounces or grams makes a lethal dose for rats using Talon G?
When Talon (brodifacoum) first came on the market as the first single feeding anticoagulant rodenticide we were told by the manufacturer that a single pellet was sufficient to kill a house mouse and 3 pellets could kill a typical rat. Clearly this is not much bait, attesting to the higher toxicity of the active ingredient. In fact the LD-50 of pure brodifacoum to a Norway Rat is 0.27 mg/kg, compared with warfarin (58 mg/kg) or diphacinone (3.0 mg/kg). I took these numbers from a resource by Cornell University.
