摘要
通过在大豆结荚初期喷施不同剂量240 g/L氯氟醚·吡唑酯乳油,并与吡唑醚菌酯悬浮剂+苯醚甲环唑悬浮剂进行对比,研究240 g/L氯氟醚·吡唑酯EC对促进大豆生长、提高产量、减少农药用量的效果.试验中,该药剂表现出较好的抗病增产作用,大豆籽粒光滑圆润,促进提早成熟.通过调查,喷施240 g/L氯氟醚·吡唑酯EC对大豆褐斑病的防效可达96%以上,大豆叶片浓绿,产量比清水对照增加22.1%;对照药剂对大豆褐斑病的防效为72%,产量比清水对照增加16.2%.试验结果表明,按240 g/L氯氟醚·吡唑酯EC 750 mL/hm2的量使用,防治大豆褐斑病效果最佳,增产效果显著,可大面积推广.
Abstract
By spraying different doses of fungicide 240 g/L chlorofluoroether·pyrazole ester EC during the early stage of soybean podding,and comparing it with pyrazolate suspension and difenoconazole suspension,the effects of 240 g/L chlorofluoroether·pyr-azole ester EC on promoting soybean growth,increasing yield,and reducing pesticide use were demonstrated,providing scientific ba-sis for promotion and application.Through experiments,this agent has shown good resistance to disease and increased yield,with smooth and round soybean seeds,promoting early maturity.Through investigation,the control effect of spraying 240 g/L chlorofluo-roether·pyrazole ester EC on Septoria glycines can reach over 96%.The soybean leaves are thick green,and the yield increases by 22.1%compared to the water control.The control agent had a 72%control effect on Septoria glycines,and the yield increased by 16.2%compared to the water control.The experimental results showed that the use of 240 g/L chlorofluoroether·pyrazole ester EC 750 mL/hm2 has the best control effect on Septoria glycines,with significant yield increase.It can be widely promoted in production.
