3种杀菌剂防治稻曲病田间药效试验

The Prevention and Control Test of Three Fungicides on False Smut for Rice

为提高水稻稻曲病的防治效果,选用27.8%福赛SC(13.9%苯醚甲环唑·13.9%赛呋酰胺)等3种药剂对稻曲病进行药效对比试验。结果表明:27.8%福赛SC(13.9%赛呋酰胺·13.9%苯醚甲环唑)每667m^2用25 m L和30%福连SC(8%戊唑醇·22%多菌灵悬浮剂)每667m^2用70 m L的防效及对水稻制种田的增产效果均显著高于常用杀菌剂30%爱苗EC(15%苯醚甲环唑·15%丙环唑)每667m^2用20 m L的处理。

In this paper,in order to improve rice disease control effects,27.8% forsyth SC（13.9% phenyl ether Jia Huan azole,13.9% cefuroxime amide）of rice disease piece for three kinds of agents such as efficacy.Results showed that the 27.8% the SC（13.9% cefuroxime acid,13.9% phenyl ether）per 667m^2 with 25 m L and 30% the SC（8%,22% carbendazim e listed suspending agent）per 667 m^2 with 70 m L of control effect.Yield of rice seed farm effects were significantly higher than that of common fungicides 30% love EC（15% phenyl ether Jia Huan azole,15% c ring azole）per 667m^2 with 20 m L of processing.
