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。/hm2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。/hm2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。
Study on efficacy and safety of 9.5％propyrisulfuron SC on Echinochloa crusgalli and Monochoria vaginalis in transplanting paddy fields
A field test of 9.5％propyrisulfuron SC under 15～60 g a.i./hm2 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./hm2 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.
