Abstract: | Objective] The research aimed to study the effect of flucarbazone and compounded agents on controlling weeds in winter wheat field.Method] The security and control effect of flucarbazone and compounded agents were investigated.Result] 70% flucarbazone of 45.0,52.5 g/hm2 had poor control effect on grass in wheat field,and had no effect on broad-leaf grass.Compounded agents of flucarbazone and tribenuron-methyl,MCPA could improve the control effects on broad-leaf grass,but decrease the control effects on grass.Conclusion] During the period of the experiment,phytotoxicity of flucarbazone and compounded agents was not found in winter wheat field.So flucarbazone was safe for winter wheat. |
