摘　　要：[ Objective] The phytotoxicity effect of quinclorac on peanut succeeding seedlings was studied. [ Method] Peanut was taken as the indicator crop, plant height and fresh weight were adopted as bioassay indicator, the biological activity of quinclorac on peanut was determined by the method of adding quinclorac in the soil, and the residue dynamic of quinclorac in paddy soil was determined. [Result] The linear correlation equations of peanut plant height and fresh weight with the concentration range of 0.7 -8.0 mg/kg separately were y = 11.235x ＋3.818 6, R^2 = 0.969 1 ; y = 5.973 3x ＋ 6.532 8, R^2 = 0.988 2. There would be no residual phytotoxicity effect when peanut was going to be planted in the same block in the second year. [Condusion] The bioassay method was simple and exact with good repeatability.[ Objective] The phytotoxicity effect of quinclorac on peanut succeeding seedlings was studied.
