水稻纹枯病是目前影响水稻生产的主要病害之一,为了提高化学药剂的防治效果,试验选取己唑醇与噻呋酰胺复配剂为防治药剂,通过设计不同的施药时期和剂量,研究了其对水稻纹枯病的防效及其对水稻经济性状和产量的影响。结果表明:在分蘖末期和破口期,分别喷施50%己唑醇水分散粒剂6 g/667m2+24%噻呋酰胺悬浮剂20 mL/667m2,防效可达81.37%,产量比施用苯甲·丙环唑的增产6.09%,比不施药剂增产30.52%。
Rice sheath blight is one of the major diseases that affect rice production at present. In order to improve the control effect of chemical agents, we tested the combination of hexaconazole and thifluzamide as control agents. By designing different application periods and doses, Its control effect on rice sheath blight and its effect on economic traits and yield of rice. The results showed that at the late tillering stage and breaking stage, 50% hexaconazole water dispersible granule 6 g / 667m2 + 24% thiafoamide suspending agent 20 mL / 667m2 was sprayed at the end of tillering stage and the breaking stage, the control effect was 81.37% The increase of benzo-propiconazole was 6.09%, which was 30.52% higher than that of non-application.
