45％三·福可湿性粉剂防治水稻恶苗病试验研究

EXPERIMENTAL STUDIES ON EFFECTS OF“SAN-FU” WATER DLSPERSIBLE POWOER ON BAKANAE OISEASE OF RICE

１９８９～１９９４年用４５％三·福可湿性粉剂（代号９０１）５００倍浸种防治水稻恶苗病，院内试验结果表明，对恶苗病平均防效为９７．４８％，高于其它对照药剂．田间小区试验平均防效为９７．５％，高于对照药剂恶苗灵．田间示范试验平均防效为９９．０９％，高于生产上推广的恶苗灵和溴硝醇等药剂．９０１浸种防治恶苗病，防效高，病菌不易产生抗药性，用量少，成本低，使用安全、方便．

The experiments were conducted in Gongzhuling,1989 to 1994,with 45% “San-Fu”water dispersible powder(0 code: 901)to controll the bakanae disease of rice.The seeds were treated with 500x solution of the pesticide. The controll effect was 97.48%,higher than that of any other pesticide (CK).Bakanae controll with “01”treatment has advantages of high effect,less pesticide resistance of the pothogen,low cost,low harmfulness to human bodies and convenient for use.
