采用咪鲜胺、硫磺·三环唑、苯醚甲环唑、多菌灵4种常用杀菌剂开展茭白胡麻斑病防效试验。试验结果表明,25%咪鲜胺乳油1 500倍液、45%硫磺(40%)·三环唑(5%)可湿性粉剂500倍液2个处理的胡麻斑病防控效果及增产优势明显,防控效果分别达到87.4%和88.3%,产量达到1 796.2、1 758.6 kg/667 m^2。

Four types of common fungicides, including prochloraz, sulphur tricyclazole, difenoconazole and carbendazim were used to carry out the control effect trial against Helminthosporium blight of Zizania Jafa.ibJia in this study. The twotreatments, 25% prochloraz emulsifiable concentrate 1 500 times liquid and 45% sulfur （40%）＋triazole （5%） wettable powder 500 times liquid had significantly effect on controlling blight and increasing yield. The controlefficiency reached to 87.4% and 88.3%, and the yield reached to 1 796.2, 1 758.6 kg/667 m2, respectively.
