Ricestrawisamajorbyproductofthericefarmingindustryandiswidelyusedasananimalfeed,buildingmaterial,andfuel.However,duetoitsorganicnature,ricestrawishighlysusceptibletodecayandmustbetreatedtopreventfungalandinsectattacks.Inthisstudy,weinvestigatetheanti-fungalpropertiesofricestrawinahumidenvironmentanditstensilestrengthunderwetanddryconditions.

Methodology

Freshricestrawwasharvestedfromalocalfarmandcutinto10cmsegments.Thestrawwasdividedintotwogroups,onegroupwasleftuntreatedandtheotherwascoatedwithafungicidalspray.Bothgroupswerethenexposedtoahighhumidityenvironment(80%relativehumidity)forfourweeks.Aftertheexposureperiod,samplesweretakenfromeachgroupandtestedforfungalgrowthusingastandardpetridishmethod.

Forthetensilestrengthtest,ricestrawsamplesweresoakedindistilledwaterfordifferentperiods(1,2,4,8,and24hours)tosimulatewetconditions.Similarly,drysamplesweretakenascontrols.ThesampleswerethentestedfortensilestrengthusingauniversaltestingmachinefollowingtheASTMD638standard.
