Abstract：Inorder to explore weed control technology in machine transplanting rice fields using drone-assisted drip orfertilizer-mixed applicationof pyraclonilanditscompounds，a large-scale field experiment wasconducted in Xinghua City，Jiangsu Province in 2O24.Theresults showed that7days after machine transplanting rice，control ffects basedon plant and freshweight of pyraclonil 280g/L SC at 50mL/667m2 ，pyracloni ? lisoproturon 420 g/L SC at

80 mL/667 m2 and pyraclonil 280g/L SC at40 mL/667 m2+flufenacet 41% SC at 10 mL/667 m2 using drone - assisted drip or mixed fertilizer application were over 93% onEchinochloa spp.，Leptochloa chinensis（L.） Nees.， Pontederia vaginalis Burm.f.，Ammannia muliflora Roxb.，and Cyperus diffrmis L.，and wereselectivitytorice. Once applicationofherbicideviadrone-asisteddriporfertilizer-mixedapplicationefectivelycontrolled weeds throughoutthe entiregrowth periodof machinetransplanting rice.Compared totheconventional herbicideapplication method which involved drone-assisted application of bensulfuron-methyl ? pretilachlor 35% WP at 120 g/667 m2 mixed with fertilizer3 days before rice transplanting，followed by manual applicationof cyhalofop-butyl 20% EC at 100 mL/667 m2 + penoxsulam 25 g/L OD at 120 mL/667 m2 + bentazone 480 g/L SL at 175 mL/667 m2 20 days after transplanting，thisdrone-basedapproach significantlyreduced herbicideusage，saved labor costs，and enhancedthe efficiency of herbicide application.
