杂草严重影响豌豆产量和品质，制约豌豆产业发展。为了筛选安全、高效的除草剂，选用3种芽前土壤封闭除草剂和6种苗后茎叶处理除草剂，在大田试验条件下进行作物安全性及杂草防除效果评价。结果显示，480 g/mL氟乐灵乳油和460 g/mL 2-甲-灭草松可溶液剂防效较好，施药后30 d株防效分别为76.88%、64.52%，施药后60 d株防效分别为75.86%、66.98%，鲜重防效分别79.59%、71.43%。24%乙氧氟草醚乳油对豌豆产生轻微药害；250 g/mL氟磺胺草醚水剂药害较重，严重抑制豌豆生长，应慎用。建议豌豆田杂草防除优先选用480 g/mL氟乐灵乳油和460 g/mL 2-甲-灭草松可溶液剂。

Weeds are the major limiting factors for the low productivity and quality in peas, restricting industrial development of pea. In order to screen safe and efficient herbicides, three kinds of pre-budding soil sealing herbicides and six kinds of post-seedling stem and leaf treatment herbicides were selected to evaluate the crop safety and weed control effect under field test conditions. The results showed that 480 g/mL fluralin emulsifiable concentrate and 460 g/mL 2-methyl-metamoxacol soluble concentrate had better control effects, and the control effects were 76.88% and 64.52% of strains 30 days after application. After 60 days of application, the control efficiency of the isolates were 75.86% and 66.98%, and the fresh weight control effects were 79.59% and 71.43%, respectively. Furthermore, 24% Oxyfluorofe emulsifiable concentrate caused slight pesticide injury to peas, 250 g/mL Fomesafen aqueous solutions had severe phytotoxicity, and seriously inhibited the growth of peas. It is suggested that 480 g/mL fluralin emulsion and 460 g/mL 2-methyl-methaNO_xacol soluble concentrate should be preferred for weed control in pea fields.
