摘  要:
[Aims] This study aims to evaluate the control effects and safety of eight foliar applied herbicides to provide a basis for the weed control in peanut fields. [Methods] The field trial was carried out by foliar treatment. [Results] The results showed that both the plant and fresh weight control efficacies were more than 95% on annual weeds in peanut field after 40 d treatment when applied the herbicides, at the effective dosages of quizalofop-p-ethylofluoroglycofen-ethyl15% EC, quizalofop-p-ethyloacifluorfenobentazone 37% ME and quizalofop-p-ethylofluoroglycofen-ethyloimazameth12% ME were 135.00, 832.50 and 180.00 g a.i./ha, respectively. [Conclusions] Quizalofop-p-ethylofluoroglycofenethyl,quizalofop-p-ethyloacifluorfenobentazone and quizalofop-p-ethylofluoroglycofen-ethyloimazameth show good control to annual weeds in peanut field and are safe on peanut growth.
