摘要
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 30d株防效分别为 76.88%、64.52%,施药后60d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.
Abstract
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-methanoxacol soluble concentrate should be preferred for weed control in pea fields.
