摘要:
介绍了应用丁草胺+农得时、除稗特+草克星、稻思达+威农、禾大壮+太阳星、神锄+莎多茯等5种复配除草剂在稻田杂草三个不同时期的安全性及防治效果。试验结果表明:丁草胺1500mL/hm2+农得时225 g/hm2、除稗特900 g/hm2+草克星150 g/hm2、稻思达90 g/hm2+威农150g/hm2对低龄杂草防效较好,总防效分别达到98.8％、99.1％和98.9％;禾大壮1 500 mL/hm2+太阳星150 g/hm2和神锄300 g/hm2+莎多茯150 g/hm2对3龄时期杂草防效较好,总防效达到96.7％和96.3％,且对水稻生长无不良影响。
Abstract:
The Preliminary Report on the Control Efficiciency of Weed ofSeveral Complex Herbicides in Rice Seedling Bed at Different Stage1002-2767(2002)06-0011-03Abstract: The paper introduced the safety to rice and the control efficiency of five sorts of com-plex herbicides: butachlor and bensulfuron methyl , mefenacet and pyrazosulfuron-ethyl . top-star and methyl 2-benzoate , ordrarm ancl sunstar , quinclorac and cinosulfuron at three differ-ent rice weed growing stage. The results showed that the control efficiency of butachlor 1500ml/h m2 and bensulfuron 225g/h m2 , mefenacet 900g/h m2 and pyrazosulfuron-ethyl 150g/h rTf . top-star 90g/h m2 and methyl 2-benzoate 150g/h m2 was better in early stage of weed, the total con-trol efficiency was up t0 98. 8% , 99. 1% and 98. 9% respectively . The control efficacy of ordram1500ml/h nf and sunstar 150g/h m2 , quinclorac 300g/h mz and cinosulfuron 150g/h m2 was betterat three-leaf stage of weed, and the total control efficiency was up t0 96. 7% and 96. 3% respec-tively. All of those complex were harmless to rice.
