[ Method] The field trids were carried out by routine spraying method, and the control effects of mixtures of Beichuang （ Liangfenbao and Jianweikang） and less dose of phoxim than conrentional against B. odoriphaga larvae were examined. [Result] The results indicated that the control effects of mixtures （containing 14% of Liandeibao or Jian- veikang and 30% -40% less phoxim than conventional dosage） against B. odoriphaga larvae were 84.01% -2.46% and 81.07% -86.12%, respectively. The mntrol effects were equivalent to the conventional dose of phoxim （89.42%）. [ Conclusion] When Beichuang is mixed with phoxim in controlling B. odor/phaga arvae, the suitable reduction level of phoxim is 30% -40%.展开更多
为验证示范药剂的减药增效作用,2019—2020年度在种粮大户承包地内设立防治小麦病虫减药增效大区示范.示范结果表明,减量示范区每667 m 2农药使用量235 g,较常规处理区减少29.0%;减量示范区每667 m 2实际产量为605.6 kg,分别较常规处理...为验证示范药剂的减药增效作用,2019—2020年度在种粮大户承包地内设立防治小麦病虫减药增效大区示范.示范结果表明,减量示范区每667 m 2农药使用量235 g,较常规处理区减少29.0%;减量示范区每667 m 2实际产量为605.6 kg,分别较常规处理区、空白对照区增加19.8%,39.9%,比常规处理区每667 m 2增加纯效益184.10元.展开更多
