Abstract：Asabroad-spectrum，low-toxicityandefficientfungicide，tebuconazole（TB）hasbeenwidelyusedinagricultural production.However，theexisting formulationsof TB fungicidesaremostlywetablepowders，suspensionconcentrate， emulsifiableconcentrate，whichexhbitdisadvantagesoflowefectiveutilzatioandenvionmentalpolution，soitisurentto developnewsystems toachieveenvironmentallfriendlyandeficientdeliverysystems.Inthisstudy，grapheneoxide（GO） wasused as the nanocarrier of TB，and GO loaded TB nanocomposites（TB @GO ）weresuccessfully prepared by physical adsorption method.The results showed that the adsorption capacity of GO for TB reached up to 2846mg/g ，significantly improving the loadingrateofTB.Further research indicated that TB@GOcould achieve effectiverelease under various conditionsofonicsrength，pHvaues，andtmperatures，demonstrating excellentcontroled-eleaseproperties.Particlarlyin aqueous systems， TB @GO achieved five effective releases， significantly enhancing the utilization rate of TB. This research providesnewideasandbroad prospects fortheapplicationofgraphene-based materialsinthefieldof pesticidecontroled release.TB@GO nanocomposites notonlyenhancethe efectiveutlizationrateof pesticides but alsoreduce the amountof pesticide applicationand environmental polution，providing anewsolution for the developmentof greenagriculture.
