Abstract：Inordertoclarifythecontrolefectofdifferentherbicidesonone-year-oldweedsingingerfield，tentreatments were carried out in 2-4 leaf stage after ginger emergence and 2-4 leaf stage of weeds，including 4 doses of 18% haloxyfop-R-methyl·fluroxypyr·dichloropyridine acid dispersible oil suspension per 667m2 40mL of 108g?L-1 haloxyfop-R-methyl EC， 60mL of 200g?L-1 fluroxypyr ·isooctyl EC， 45mL of 30% dichloropyridine acid AS， 50mL of 240g?L-1 oxyfluorfen EC，artificial weedingand blank control.Evaluate the weeding effect andsafety.Theresults showed that after15and 35 days of application，the plant control effect of 4 doses of 18% fluroxypyr·clopyr ??ε dichloropyrdispersible oil suspension agent on the target weeds reached more than 75.00% .The plant control effect of 4 doses of 18% fluroxypyr ∵ clopyr·dichloropyr dispersible oil suspension agent on Eclipta prostrata and Medicago minima was significantlybeter thanthatonPortulaca oleraceaand Setariaviridis.The plantcontrol efectof180 gper 667m2 onMedicago minima and Eclipta prostrata reached 100.00% ，and the fresh weight control effect on the target weeds eached more than 85.00% .Among them，the fresh weight control effectsof 100g and 180g per 667m2 onMedicagominima and Eclipta prostrata reached up to 100.0% .The fresh weight control effect of the dosage of the tested agents on the fresh weight ofEcliptaprostrataandMedicagominima wassignificantlybetterthanthatofPortulacaoleraceaandSetariaviridis.

There wasnosignificant effectonthe growthof gingerand other non-target organisms ateach stage after theapplication of the tested agents.The yield increase rate of 18% fluroxypyr·fluroxypyr·dichloropyr dispersible oil suspension at 80，90，100 and 180g per 667m2 was more than 15% .It can be popularizedand applied inginger field production.
