The avian acute oral toxicity test (avian single-dose LD₅₀) for new pesticides "Shaman" (cypermethrin — 50 g/l and chlorpyrifos — 500 g/l), "Cethodim" (clethodim — 240 g/l) with surface-active substance "Fofir" (1:3), "Triumph" (phenmedipham — 91 g/l, desmedipham — 71 g/l, ethofumesate — 112 g/l), "Batu" (rimsulfuron — 500 g/kg and thifensulfuron methyl — 250 g/kg) with surface-active substance "Talant" (25 g "Batu"/200 ml "Talant") was provided. Japanese quails (Coturnіx coturnіx japonіca) were treated with a single oral dose of one of these pesticides in different doses. It was shown that LD₅₀ of "Shaman" was 25,2±1,2 mg/kg body weight, LD₅₀ of "Cethodim" was 32807±1780 mg/kg body weight, LD₅₀ of "Triumph" was 7642±444 mg/kg body weight, LD₅₀ of "Batu" was 1036±54 mg/kg body weight.
