中文摘要:

铁苋菜（Acalypha australis L.）在黑龙江省大豆田的种群数量及其危害日益严重，农民已将其列为难防杂草。采用盆栽试验方法，筛选了防治铁苋菜的茎叶处理除草剂。结果表明，灭草松、噻吩磺隆、异噁草松、咪唑乙烟酸对2～6叶期铁苋菜无防除效果；防除2叶期铁苋菜，可以施用氟磺胺草醚300 g/hm2、乳氟禾草灵90 g/hm2、乙羧氟草醚60 g/hm2；防除4叶期铁苋菜，氟磺胺草醚施药量需高于300 g/hm2，乙羧氟草醚的施药量需高于90 g/hm2；防除6叶期铁苋菜，仅能施用氟磺胺草醚，且施药量需高于300 g/hm2。

英文摘要:

The population and damage of Acalypha australis L. are increasing in soybean fields in Heilongjiang Province, and farmers regard it as the troublesome weed. Pot experiments were conducted to screen postemergence herbicides for controlling A. australis. The results showed that bentazone, thifensulfuron, clomazone or imazethapyr could not control 2 leaf through 6 leaf A. australis. Two leaf A. australis could be controlled by formesafen with an application rate of 300 g/hm2, lactofen with an application rate of 90 g/hm2 or fluoroglycofen ethyl with an application rate of 60 g/hm2. To control 4 leaf A. australis, the application rate of formesafen should be more than 300 g/hm2, and that of fluoroglycofen more than 90 g/hm2. Six leaf A. australis could only be controlled by formesafen with an application rate of more than 300 g/hm2.
