摘  要：
氟磺胺草醚在施药不均匀,剂量倍加的情况下可对大豆和后茬敏感作物产生药害。盆栽试验表明,氟磺胺草醚剂量为750g/hm2时对大豆株高有显著影响,剂量为1500g/hm2时大豆株重显著下降。间隔90d播种作物,剂量为495g/hm2时玉米和小麦株重显著下降;剂量为562.5g/hm2时,对油菜株重显著下降;而在推荐剂量375g/hm2时,玉米、小麦和油菜的株重没有显著影响。氟磺胺草醚与灭草松混用可以降低前者的使用剂量,是降低药害风险良好的措施。

摘  要：
Fomesafen unevenly applied at 2x rates can injure susceptible crops. Potted plant experiments indicated significant soybean plant height reductions with fomesafen at 750 g/ha, and significant soybean plant weight reduc- tions at 1500 g/ha. Corn and wheat plant weights were reduced significantly when seeded 90 d after application of fomesafen at 495 g/ha. Rapeseed plant weights were significantly reduced when seeded 90 d after application of fomesafen at 562.5 g/ha, while plant weights of corn, wheat, and rapeseed were not significantly affected when seeded 90 d after application of the recommended fomesafen rate of 375 g/ha. Application in mixture with bentazon allowed reduction of the fomesafen use rate and thus provided a useful means of reducing fomesafen crop injury.
