AbstractThe current situationof gramineous weeds in wheat fields was examined in Mengcheng County，Bozhou， AnhuiProvince，the reasons for their increasing prevalencewere analyzed，and integrated control measures were proposed. Over the past decade，gramineous weeds in the studyarea，including Avena fatuaL.，Aegilops tauschi Coss， and Alopecurus myosuroides Huds，have spread rapidly.The exacerbating factors includethe contaminationof wheat seeds with weed seeds，insufficient deep plowing ortillage in field management，improperuseofcombine harvesters and straw balers，the decline inbroadleaf weedcommunities，and the strong vitalityof the weeds.Basedon these findings， integrated control measures for gramineous weeds are proposed.These include avoiding the introduction of wheatseeds fromareas with high weed infestation to preventthe spread of weed seeds via contaminated seeds;implementing deep plowing or tillage （toa depth ofover 25cm）tosuppress weed growth; thoroughlycleaning combine harvesters and balers to reduce thespread of weed seeds by machinery;and adhering to the principleof“combining pre-emergence control with post-emergence treatment，along with scientific herbicide application.”Recommended practices include soil sealing with herbicides such as flufenacet before wheat emergence after sowing，and around15 days after sowing （at the 1-leaf and1-heart stage of wheat seedlings）before frost and temperature drop，using herbicides like isoproturon for combined pre-and post-emergencecontrol.After the wheat reaches the 4-5 leaf stage in winter，herbicides such as clodinafop-propargyl can be selected for stem and leaf treatment.This study provides areference for the control of gramineous weeds in wheat fields.
