摘要:

为明确氟噻草胺在水稻田的应用效果,2023年开展了田间大区试验,研究氟噻草胺对稻田杂草的防治效果和对水稻秧苗的安全性。结果表明,在水稻移栽前、移栽后使用氟噻草胺封闭处理,于药后15 d和50 d对禾本科杂草(特别是稗草和千金子)株防治效果和鲜重防治效果可达92.0%~98.0%,但对阔叶杂草的株防治效果和鲜重防治效果仅为50.0%左右。施药方式(喷雾或拌土)、药后是否保水对氟噻草胺的封闭效果影响小,各处理的防治效果均在90.0%以上。使用氟噻草胺后,水稻正常生长,处理区产量较空白对照显著增加。建议在水稻生产中根据实际情况,灵活使用氟噻草胺进行封闭处理,并搭配使用阔叶草封闭除草剂。

Abstract:

To clarify the application effect of flufenacet in rice fields, a large-scale field experiment was conducted to study its herbicidal effect and safety on rice seedlings in 2023. The result showed that when flufenacet was used for sealing treatment before and after rice transplanting, the seedling control effect and fresh weight control effect against grassy weeds (especially Echinochloa crus-galli and Leptochloa chinensis) could reach 92.0% to 98.0% at 15 days and 50 days after application, but the seedling control effect and fresh weight control effect against broadleaf weeds were only about 50.0%. Different application methods(spray or soil mix), and different management after medication (whether water is preserved after medication), the control effect is more than 90.0%, have little influence on flufenacet. After the application of flufenacet, rice grew normally and yield increased obviously than control group. It is recommended that in rice production, flufenacet could be flexibly used for sealing treatment based on actual conditions, with broadleaf grass sealing herbicides used in combination.
