水稻褐变穗药剂防治效果试验研究

Study on Efficacy Trials to Brown Panicle Disease in Rice

通过不同药剂对水稻褐变穗病田间防治效果的试验研究,结果表明,这几种药剂对水稻褐变穗病的防治、产量的提高均有效果,与清水对照相比爱可防效最高,达到74%;拿敌稳次之,为69.13%;尊保第三,防效为59.79%;多抗霉素第四,防效为48.03%;磷酸二氢钾防效最低,为28.03%。拿敌稳较对照相比增产率最高达到6.71%;爱可排名第二,比对照增产率为6.43%;尊保和磷酸二氢钾表现一般,增产率分别为0.95%和3.08%。

Study on efficacy trials to brown panicle disease in rice were researched by different pesticides and the result indicated that pesticides had certain effect on control diseases and increase yield. Compared with control of water, Aike had the best control efficiency with 74%; followed by Nadiwen on control efficiency with 69.13%; Zunbao was ranked third by control efficiency with 59.79%; Duokangmeisu was ranked fourth by control efficiency with 48.03%; Monopotas- sium phosphate had the lowest control effect with 28.03%. Compared with control of water, Nadiwen had highest yield- increase rate with 6.71%; followed by Aike on yield-increase rate with 6.43%; Zunbao and Monopotassium phosphate were performing normally by yield-increase rate with 0.95% and 3.08%.
