Ingca yesanti sisityalo “sesincamathelisi” esikhangeleka njengengca.Idla ngokungena kwingca engcakacileyo, ngakumbi kwiminyaka eyomileyo.Ngoko ke, olona lawulo lulungileyo kolu khula yingca engqindilili nesempilweni.Nangona kunjalo, ukuba ingca yakho ibhityile kakhulu kule ntlakohlaza kwaye isanti yengca yonyaka ophelileyo yingxaki, sebenzisa umchiza wokutshabalalisa ukhula phambi kokuvela kwesanti.Nangona kunjalo, ayizizo zonke imichiza yokutshabalalisa ukhula ezisebenzayo.Iimveliso ezintathu ezinokunceda ukunciphisa ukunqunyulwa kwengca ngumququ, i-pendimethalin kunye nepropylenediamine.
I-Oryzalin ithengiswa phantsi kwegama le-brand Weed Impede.Ingasetyenziswa kuyo yonke ingca yexesha elishushu kunye nengca yefescue ende.Ngaphandle kwefescue kunye nezinye iingca zefescue ezide, akufanele zisetyenziswe kwingca kwixesha elipholileyo, njengeKentucky bluegrass.I-Oryzalin nayo inokuthengiswa njengendibaniselwano yeGreen Light Amaze kunye ne-benefin.Njengomququ wodwa, ungasetyenziselwa zonke iingca zexesha elifudumeleyo kunye nengca yefescue ende.Ngaphandle kwefescue kunye nezinye iingca zefescue ezide, akufanele zisetyenziswe kwingca kwixesha elipholileyo, njengeKentucky bluegrass.Xa umthi we-bauhinia udubula ngokupheleleyo, sebenzisa iimveliso ze-Amaze okanye i-Oryzalin malunga ne-15 ka-Epreli.
I-Pendimethalin ithengiswa njengePendulum kwimarike, kwaye kukho namanye amagama amaninzi.Kwicala lomninimzi, ithengiswa njengeScotts Halts.Kungcono ukusebenzisa i-Pendimethalin ngokwahlukileyo, isiqingatha sokuqala siya kusetyenziswa malunga ne-15 ka-Apreli, kwaye inxalenye yesibini iya kusetyenziswa malunga ne-1 kaJuni.Okanye, yenza isicelo sokuqala xa umthi we-bauhinia udubule ngokupheleleyo, kunye neeveki ezintandathu emva kweveki yesibini.
Ipropylenediamine ithengiswa phantsi kwegama lezorhwebo elithi Barricade.Ikwathengiswa njengemveliso yomninimzi Howard Johnson Crabgrass Control Plus kunye 0.37 Prodiamine 00-00-07.Ingasetyenziswa kuzo zonke ingca yethu eqhelekileyo.Malunga ne-15 ka-Epreli okanye xa i-bauhinia idubula, i-spartina isasetyenziswa.Sinye kuphela isicelo esifunekayo ngonyaka.
Akukho “michiza yokutshabalalisa ukhula” inokulawulwa ngokupheleleyo, kodwa ngamnye kufuneka ancede.I-Quinclorac (i-drive) inokubonelela ngolawulo oluthile emva kokuhluma, ngakumbi ukuba i-sand bur ikwinqanaba lezithole.I-Quiniclac ikwafumaneka kwiimveliso ezininzi ezidityanisiweyo ezilawula zombini ukhula lwamagqabi abanzi kunye ne-crabgrass, njengenye yezi mveliso zilandelayo: Ortho Weed-B-Gon Max + Crabgrass Control;Ortho Weed-B-Gon Max + Crabgrass Control ;Ortho Weed-B-Gon Max + Crabgrass Control;BioAdvanced zonke-in-enye ukhula kunye crabgrass umbulali;Monterey Crab-E-Rad Plus;i-fertility herbicide crabgrass killer;Trimec Crabgrass Plus yokutshabalalisa ukhula;Ukukhula kwebhonidi Yongeza ingca engu-C kunye nomchiza wokutshabalalisa ukhula;I-Spectracide herbicide, ilungele ingca kunye nombulali wecrabgrass.
