常用杀菌剂对水稻恶苗病菌的毒力测定
Toxicity Determination of Commonly Used Fungicides Against Fusarium fujikuroi
摘要
Abstract
In order to clarify the inhibitory effect of fungicides on the growth of Fusarium fujikuroi,the mycelial growth rate method was used to determine the inhibitory ability of 10 fungicides and prochloraz combined with oxamycin,among them,fluconazole,carbendazim,fludioxonil,phenamacril and prochloraz all had strong antibacterial activity,EC5o values were 0.012,0.21,0.22,0.46 and 0.80 μg·mL-1 respectively.The EC50 values of boscalid,thiram and hymexazol were between 50 and 150 μg·mL-1,and the inhibitory effect was relatively weak.When EC50 values of azoxystrobin and chlorothalonil were greater than 1 000 μg·mL-1,the antibacterial effect was the weakest.When the compound ratio of prochloraz and hymexazol was 8:2,it showed synergistic effect,and the co-toxicity index was 126.58.When the mixture ratio was 9∶1,it had additive effect,and the co-toxicity index was 92.46.The other four combinations(7∶3,6∶4,5∶5,4∶6)showed antagonistic effects,and the co-toxicity index were less than 80.Fluconazole,carbendazim,fludioxonil,phenamacril and prochloraz had good antibacterial effect,and the compound ratio of prochloraz and hymexazol was 8∶2,which had synergistic effect,and could provide a theoretical basis for the control of rice bakanae disease in the field.关键词
