摘要
[目的]明确8种茎叶处理除草剂对花生田杂草的防除效果和对花生的安全性。[方法]采用田间小区试验方法进行药效试验。[结果]15%精喹禾灵·乙羧氟草醚EC、37%精喹禾灵·三氟羧草醚·灭草松ME和12%精喹禾灵·乙羧氟草醚·甲咪唑烟酸ME的剂量分别为135.00、832.50、180.00 g a.i./hm^2时,药后40 d对花生田一年生杂草防效均达到95%以上。[结论]精喹禾灵·乙羧氟草醚、精喹禾灵·三氟羧草醚·灭草松和精喹禾灵·乙羧氟草醚·甲咪唑烟酸可有效防除花生田杂草,并对花生有较好的安全性。
[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.
