摘要
为了筛选出防除豚草和薇甘菊的新型高效除草剂品种,采用茎叶喷雾法,测定30种除草剂对盆栽豚草和薇甘菊的防除效果。辛酰溴苯腈375g/hm2、麦草畏216g/hm2、百草枯600g/hm2、草铵膦540g/hm2、草甘膦异丙胺盐922.5g/hm2、乙羧氟草醚90g/hm2、三氟羧草醚540g/hm2、氟磺胺草醚427g/hm2、莠去津1 140g/hm2、莠灭净3 000g/hm2和灭草松1 440g/hm2对豚草防除效果好,药后30d鲜重防效达100%;对薇甘菊防效较好的有辛酰溴苯腈375g/hm2、麦草畏216g/hm2、2,4-滴钠盐125g/hm2、氯氟吡氧乙酸180g/hm2、氯氟吡氧乙酸异辛酯150g/hm2、草铵膦540g/hm2、草甘膦异丙胺盐922.5g/hm2、灭草松1 440g/hm2和百草枯600g/hm2,药后30天鲜重防效达98%以上。本试验结果将为豚草和薇甘菊的化学防控提供有益参考。
In order to screen new effective herbicides against the ragweed Ambrosia artemisiifolia and South American climber Mikania micrantha,the chemical control effects of 30 kinds of herbicides were tested during the seedling stage of ragweed and South American climber by foliar spraying method.The results showed that 11 kinds of herbicides,namely bromoxynil octanoate (375 g/hm2),dicamba (216 g/hm2),paraquat (600 g/hm2),glufosinate-ammonium (540 g/hm2),glyphosate-isopropylammonium (922.5 g/hm2),fluoroglycofen-ethyl (90 g/hm2),acifluorfen-sodium (540 g/hm2),fomesafen (427 g/hm2),atrazine (1 140 g/hm2),ametryn (3 000 g/hm2) and bentazone (1 440 g /hm2) had significant control effects against ragweed,of which the fresh weight control effects were 100% after 30 d.Bromoxynil octanoate (375 g/hm2),dicamba (216 g/hm2),2,4-D sodium (125 g/ hm2),fluroxypyr (180 g/hm2),fluroxypyr-meptyl (150 g/hm2),glufosinate-ammonium (540 g/hm2),glyphosate-isopropylammonium (922.5 g/hm2),bentazone (1 440 g/hm2) and paraquat (600 g/hm2) were effective against South American climber with a fresh weight control effect of more than 98%.The results can provide guidance on the chemical control of the ragweed and South American climber.
