摘　　要：JSW002、JSW021是以芳氧苯氧丙酸类和氰基丙烯酸酯类拼接而成的具有除草活性的化合物。针对这两种化合物进行了室内除草活性筛选和作物安全性评价试验,表明JSW002、JSW021对禾本科杂草有较好的防除效果,对大豆、油菜等作物安全,在低剂量情况下对禾本科杂草的防治效果略逊于同剂量下对照药剂精喹禾灵。JSW002 and JSW021 belonged to quinoxalyloxy phenoxy propionate derivative, their chemical structure was made up of quinoxalyloxy phenoxy and cyano propenoate. Their herbicidal activity and safety were tested in greenhouse. JSW002 and JSW021 were high efficacy against gramineous weeds, for example, Green bristlegrass （Setaria viridis（L.）Beauv）, Common crabgrass （Dig#aria sanguinalis（L.）Scop）, Equal alopecurus （Alopecurus aequalis Sobol）, Barnyardgrass （Echinochloa crusgalli（L.）Beauv.voa＇.）, Chinese Sprangletop （Leptochloa chinensis（L.）Nees） and Bermudgrass （Cynodon dactylon（L.）Pars.）. They were safety to soybean and oilrape. But their herbicidal activity was lower than quizalofop-P at the same dosage.
