Control Effects of Different Herbicides Combinations on Lolium multiflorum Lamk.in Wheat Fields
A trial was carried out to explore effects of different herbicides on Lolium multiflorum Lamk.in wheat fields where 17 herbicides combinations were set up in Yicheng District,Zhumadian City,Henan Province in 2021-2022.The results showed that the best pre-emergent herbicide for weed control was pretilachlor 500 g/L EC at 100 mL/667 m2+isoproturon 50％ SC at 150 mL/667 m2,while pre-emergent effect of flufenacet·diflufenican 35％SC at 77 mL/667 m2 was not significantly different from that of pretilachlor 500 g/L EC at 200 mL/667 m2 .The best post-emergent herbicide for weed control was pinoxaden 5％ EC at 100 mL/667 m2+isoproturon 50％ SC at 150 mL/667 m2+water-soluble fertilizer containing amino acids at 50 mL/667 m2,followed by pinoxaden 5％ EC at100 mL/667 m2+isoproturon 50％ SC at 150 mL/667 m2,and then pinoxaden 5％ EC at 200 mL/667 m2 .The best combination of pre-and post-emergent herbicides for weeds control were flufenacet·diflufenican 35％ SC at 77 mL/667 m2+pinoxaden 5％ EC at 100 mL/667 m2+isoproturon 50％ SC at 150 mL/667 m2,followed by pretilachlor 500 g/L EC at 100 mL/667 m2+pinoxaden 5％ EC at 100 mL/667 m2+isoproturon 50％ SC at 150 mL/667 m2,and then pretilachlor 500 g/L EC at 100 mL/667 m2+isoproturon 50％ SC at 150 mL/667 m2+pinoxaden 5％ EC at 100 mL/667 m2 .In summary,combination of pre-and post-emergent herbicides for efficient control of the invasive weed L.multiflorum in wheat fields.In the selection of herbicides,the pre-emergent herbicides could be used with pretilachlor,pretilachlor+isoproturon or flufenacet·diflufenican,and post-emergent herbicides were selected with pinoxaden or pinoxaden+isoproturon.By carefully selecting pre-and post-emergent herbicides and following scientific guidance,effective control of L.multiflorum in wheat fields could be achieved.
