为明确新化合物O,O-二甲基-1-(2,4-二氯苯氧基乙酰氧基)呋喃甲基膦酸酯(HIA-1)的开发应用前景,对其除草活性、杀草谱、对作物的安全性、施药适期、吸收部位进行了综合评价.温室盆栽试验结果表明:该化合物在有效成分用量为600 g/hm~2剂量下对苘麻、反枝苋、马齿苋等常见阔叶杂草具有较高的除草活性,茎叶处理后防效在90%以上;在有效成分用量为1 600 g/hm~2剂量下对小麦、玉米较安全,鲜重抑制率分别为9.06%和12.04%,对棉花、花生、大豆和油菜有明显的药害;使用适期为杂草2～3叶期.活性炭隔离和植株茎叶喷雾、灌根试验结果表明,该化合物可通过胚芽、胚根、根、茎、叶吸收进入植物体内.化合物HIA-1具...

In order to demonstrate the development and application value of a novel compound O, O- dimethyl-1-（ 2, 4-dichlorophenoxy-acetyloxy ）-methylfuran phosphonate （ HIA-1 ）, comprehensive evaluation on the herbicidal activity, spectrum of weed control, safety to crops, application timing and absorption site of HIA-1 were carded out. The result of pot bioassay in greenhouse showed that the efficacy of HIA-1 to most familiar latifoliate weeds such as Abutilon theophrasti, Amaranthus retroflexus and Portulaca oleracea was over 90% at dosage of 600 ...
