Abstract:

Introduction:
NematodesareagroupofmicroscopicwormsthatbelongtothephylumNematoda.Theseorganismsareknowntoparasitizeplantsandcauseseveredamagetoagriculturalcrops,leadingtosignificanteconomiclossesworldwide.Traditionalchemicalnematicideshavebeenusedtocontrolnematodeinfestations.However,theirnegativeimpactontheenvironmentandhumanhealthhasraisedconcernsovertheiruse.Therefore,thereisagrowinginterestinthedevelopmentofbio-nematicidesasanalternative,safe,andsustainablesolutionfornematodecontrol.
Methods:
1.IsolationandScreeningofMicroorganisms:Soilsampleswerecollectedfromnematode-infestedagriculturalfields.Theisolationofmicroorganismswasperformedusingadilutionplatingtechniqueonnutrientagarsupplementedwithnematodeextract.Afterincubation,coloniesshowingantimicrobialactivitywereselectedandfurthercharacterized.
2.IdentificationofNematodeAntagonisticMicroorganisms:Theisolatedmicroorganismswereidentifiedusingvariousmoleculartechniquessuchaspolymerasechainreaction(PCR)andsequencingofthe16SrRNAgene.Biochemicaltestswerealsoconductedtodeterminethephysiologicalcharacteristicsoftheselectedorganisms.
3.EvaluationofNematicidalActivity:Theisolatedmicroorganismswerescreenedfortheirnematicidalactivityagainsttargetnematodespeciesusinginvitroassays.Theassayinvolvedinoculatingthenematodeswithdifferentconcentrationsoftheisolatedmicroorganism'sculturefiltrateandmonitoringtheirmortalityrateovertime.
