为探明新药剂对水稻纹枯病的防治效果及其应用技术,从而为大面积推广应用提供科学依据,2012年8月在水稻纹枯病发病始盛期进行了30%已唑·噻呋酰胺SC等9种药剂防治纹枯病的田间药效比较试验。结果表明,供试的9种药剂对纹枯病均有一定防效,其中以每667m2用24%噻呋酰胺SC 25mL、75%拿敌稳WG 15g、20%满穗SC 20mL处理的防效较好,其防效分别达83.13%、88.60%、84.47%,持效期可维持20d以上;用药适期为纹枯病穴病率5%~10%时,用水量以60~75kg/667m2为好。 In order to explore the control effect of new pesticides on rice sheath blight and its application technology, and to provide a scientific basis for large-scale popularization and application, in August 2012, 30% oxazole thiazuron Amide SC 9 kinds of pesticides in the control of edaphicosis field efficacy comparison test. The results showed that all the 9 tested species had some control effects on sheath blight. The control efficacy was 667m2 with 24% thifluzamide SC 25mL, 75% SW 15g and 20% SC 20mL The control effect is 83.13%, 88.60%, 84.47%, respectively, and the persistence period can be maintained for more than 20d. When the suitable disease point is 5% -10% of the point blight incidence, the water consumption is 60-75kg / 667m2 As well
