在陇西县首阳镇进行了甘草褐斑病发生动态调查及药剂防治试验。结果表明，甘草褐斑病6月中旬开始发生，至8月上旬株发病率达100%，同时病害进入快速蔓延期；8月中旬病斑逐渐连片并开始大量脱落，病情指数快速增加，至9月上旬大部分田地50%植株叶片全部脱落。供试的6种杀菌剂对甘草褐斑病都具有一定的防治效果， 第1次施药后7 d，以20%丙环唑微乳剂2 000倍液和5%烯唑醇微乳剂1 000倍液防效较好，分别为65.82%、64.41%；第2次施药后14 d，10%苯醚甲环唑微乳剂1 500倍液和20%丙环唑微乳油2 000倍液防效较好，分别为90.73%和85.34%。

The dynamic survey and chemical control of Cercospora astragalis were investigated in Longxi county.The dynamic survey results showed that Cercospora astragalis was happen in mid-june， early August incidence of disease to reached 100%， the disease into rapid spread at the same time， the scab shall gradually in mid August and start to fall off， disease index increase quickly， through early September， leaves in nearly 50% of all fall off .The control test results that 6 fungicide effected control Cercospora astragalis .The 7 days after first drug delivery， 20% propiconazole 1∶2 000 and 5% diniconazole 1∶1 000 control effect reached 65.82%、 64.41% respectively .The 14 days after second drug delivery， 10% of difenoconazole 1∶1 500 and 20% propiconazole 1∶2 000 control effect reached 90.73% and 85.34% respectively .
