To explore the degradation effects of AMF on the residual of tricyclazole in the soil and plant of rice, we assay the residual quantity of tricyclazole in soil and plant of rice which were set by different AMF and different concentration. The results showed that the infection rate was significantly increased after applying agent. The infection rate of GI+GM was 56.06％, which was better than that of GM with 53.86％ and GI with 34.57％. The digestion rate of tricyclazole of those treatments with AMF was bigger than that without AMF. The half-life period of tricyclazole of those treatments with AMF were shorter than that without AMF. The digestion effect of three AMF on tricyclazole in soil was GM+GI> GM> GI. AMF got the best effect at 150％ which was the one of four different concentrations. The digestion effect of three AMF on tricyclazole in plant was GM> GM+GI> GI, GM and GM+GI got the best effect at 150％.
