摘要: 为了明确防除水稻移栽田阔叶杂草的有效药剂,研究3%吡氟酰草胺颗粒剂对水稻移栽田阔叶杂草的防除效果及对水稻的安全性。水稻移栽前1 d在田块均匀撒施药剂,药后20、40 d对水稻的生长和阔叶杂草的防效进行调查。结果表明,3%吡氟酰草胺颗粒剂能有效防除丁香蓼(Ludwigia prostrata)、鸭舌草(Monochoria vaginalis)、鳢肠(Eclipta prostrata)等一年生阔叶杂草,施药后对杂草生长的抑制作用明显,对水稻安全,推荐施用3%吡氟酰草胺颗粒剂用药量135~225 g (a.i.)/hm2

Abstract: In order to identify the effective agent to prevent and remove broadleaf weeds in rice transplanting field, the control effect and safety of 3% diflufenican granules on broadleaf weeds in rice transplanting field were studied. One day before rice transplanting, the field was evenly distributed with the herbicide, and the growth of rice and the control effect of broadleaf weeds were investigated regularly after spraying herbicide 20, 40 days. The results showed that 3% diflufenican granules could effectively prevent and eliminate annual broadleaf weeds such as Ludwigia prostrata, Monochoria vaginalis, Eclipta prostrata. After application, the inhibition effect of 3% diflufenican granules on the growth of weeds was obvious, and it was safe for rice. It was recommended to apply 3% diflufenican granules with the dosage of 135~225 g(a.i)/hm2.

Key words: diflufenican, paddy fields, broadleaf weeds, security, efficacy
