3种杀菌剂防治稻曲病田间药效试验

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。

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

In this paper, in order to improve rice disease control effects, 27.8% forsyth SC (13.9% phenyl ether JiaHuan 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 667m2 with 25mL and 30% the SC (8%, 22% carbendazim e listed suspending agent) per 667 m2 with 70 mL of control effect. Yield of rice seed farm effects were significantly higher than that of common fungicides 30% love EC (15% phenyl ether JiaHuan azole, 15% c ring azole) per 667m2 with 20mL of processing.
