Introduction:
Riceisoneofthemostimportantcropsintheworld,providingfoodformorethanhalfoftheworld'spopulation.However,riceproductionisoftenlimitedbyvariouspestsanddiseases.Riceseedlingblight,causedbyRhizoctoniasolani,isoneofthemostdestructivediseasesinriceproduction,especiallyintheseedlingstage.Thediseasecancausedamping-off,rootrot,andleafblight,leadingtosignificantlossesinyieldandquality.Atpresent,thecontrolofriceseedlingblightmainlyreliesonchemicalfungicides.However,theresistanceofpathogenstotraditionalfungicideshasbecomeincreasinglyserious,makingiturgenttodevelopnewtypesoffungicideswithhighefficacyandlowresistance.Fluoxastrobinisanewtypeofdehydrogenaseinhibitorfungicidedevelopedinrecentyears.Studieshaveshownthatfluoxastrobincaneffectivelycontrolvariousfungaldiseasesincrops,suchaswheatheadblightandapplescab.However,thereislimitedinformationonthecontroleffectoffluoxastrobinonriceseedlingblight.Therefore,inthisstudy,weinvestigatedthepreventiveandtherapeuticeffectsoffluoxastrobinonriceseedlingblightandexploredthepotentialoffluoxastrobinasafungicideforcontrollingriceseedlingblight.
