摘　　要：2020和2021年在江西省南昌市进行了9.5%丙嗪嘧磺隆SC在15~60 g a.i./hm^(2)处理下及对照药(苄嘧磺隆和五氟磺草胺)的大田杂草防效试验,并评估其对水稻安全性和产量的影响。结果表明,9.5%丙嗪嘧磺隆SC对移栽水稻田稗草和鸭舌草均具有良好的防除效果,60 g a.i./hm^(2)剂量处理后,对稗草的株防效高达92.40%~98.91%,对鸭舌草的株防效为82.62%~89.15%。所有处理对水稻均无药害产生,并实现增产。因此,新型除草剂丙嗪嘧磺隆可有效防除移栽水稻田稗草和鸭舌草,有较好的应用价值。A field test of 9.5%propyrisulfuron SC under 15~60 g a.i./hm^(2)treatment and control drugs(benzosulfuron and pentafluorosulfamide)was conducted in Nanchang,Jiangxi Province in 2020 and 2021,as well as its effects on rice safety and yield.The result showed that 9.5%propyrisulfuron SC had good control effect on both Echinochloa crusgalli and Monochoria vaginalis in transplanting paddy fields,which the strain control effect of 60 g a.i./hm^(2)on Echinochloa crusgalli was 92.40%~98.91%,and 82.62%~89.15%on Monochoria vaginalis.All the treatments had no harm to rice and increased rice production.Therefore,the new herbicide propyrisulfuron can effectively control Echinochloa crusgalli and Monochoria vaginalis,which has good application.
