Umbuzo: Ingaba kuyasebenza ukunyanga ingca ukuthintela icrabgrass ngoku, okanye kufuneka siyilinde ikhule phambi kokuba siyibulale ngemichiza yokutshabalalisa ukhula?Kwikwindla yokugqibela, ndiye ndabeka phantsi imichiza yokutshabalalisa ukhula.Ngaba oko kwanele?Ngaba ucinga ukuba i-verbena yasinda kubusika obunzima?Inxalenye yengca yam isandula ukuhlwayelwa.
IMPENDULO: Isityalo sehawthorn owasityala kwingca yakho kunyaka ophelileyo sifile ngoku.Nangona kunjalo, ngaphambi kokuba bafe, uninzi lunokuvelisa amawaka eembewu, eziya kuntshula kwingca yakho kwiiveki ezimbalwa ezizayo.Indlela yokuthintela ukuqhushumba kwerayisi kwangethuba kukusombulula ingxaki, hayi ukuzama ukubulala ukhula emva kokuba lumile kwingca yakho.
Nangona ikwindla lixesha elifanelekileyo lokunyanga ukhula lwe-broadleaf kunye ne-herbicides, akukho nzuzo ingako ekusebenziseni i-verbena yokuthintela ekwindla, kuba i-verbena yonyaka ehlotyeni kwaye intshula ekuqaleni kwentwasahlobo endaweni yekwindla.Xa kufika iqondo lomkhenkce ebusika, izityalo ziyafa.Phambi kokuba imbewu yeverbena iqale ukuntshula kwaye ikhule, kufuneka kusetyenziswe isithintelo severbena (“pre-emergent herbicide”) kufuneka sisetyenziswe.
Kwiingca ezisanda kulinywa, kufuneka ukhethe kwaye usebenzise imichiza yokutshabalalisa ukhula ngononophelo ukuthintela ukubulala okanye ukonakalisa ingca entsha oyityalayo.Phakathi ku-Matshi ukuya phakathi ku-Epreli lelona xesha lifanelekileyo lokusebenzisa umjikelo wokuqala we-pre-emergence herbicides ukulawula ingca ye-horsetail.Le michiza igalelwa phambi kokuba imbewu yokhula intshule.Ziyakwazi ukuthintela imbewu ye-horsetail ekuhlumeni okanye ukubulala izithole ze-horsetail xa ziqala ukuhluma.Qinisekisa ukuba imveliso oyithengayo ingasetyenziswa ngokukhuselekileyo kwingca emitsha enezithako ezisebenzayo ezifana ne-siduron (Tupersan).Oku kusenokusetyenziswa ngexesha lokutyala okanye emva kokutyala entwasahlobo.Iyakwazi ukulawula ingca yomsila wehashe kunye nengca yomsila wempungutye.
Kwingca esele ikhulile, ungakhetha iindlela ezingakumbi zokulawula ukuntshula kwengca yehashe, ingca yomsila wempungutye kunye neentsiba zerhanisi, kuquka ibefen+trifluralin (Iqela), benzsulfone (Betasan, PreSan, Lescosan), kunye neAustrian Sand pine (Ronstar), pendimethalin ( Ukulawula i-Weedgrass, i-Pre-M, i-Halts, i-Pendulum), i-dithiopyr (i-Dimension), i-Prodiamine (i-Barricade) kunye ne-bensulide + oxadiazon (i-foie gras / crab grass control).Emantla eKentucky, ezi khemikhali kufuneka zisetyenziswe ngaphambi kwe-15 ka-Epreli. Landela emva kweeveki ezintandathu kwaye uyisebenzise ngokuphindaphindiweyo ukwandisa uluhlu lolawulo kulo lonke ihlobo.Ukuba i-gooseweed lolona khula ekujoliswe kulo, nceda wenze isicelo sesibini malunga ne-15 kaMeyi.
Xa kuhlwayelwe ingca, kwingca emitsha okanye emhlabeni oza kuhlwayelwa kwiiveki ezimbalwa ezizayo, ukutshatyalaliswa kokhula lwamagqabi abanzi alulo khetho lokwenyani, njengoko uninzi lwemichiza yokutshabalalisa ukhula luya kubulala iidandelions, clover, kunye neplantain Grass, violets, ivy, njl. Iqulethe i-2,4-D okanye iimveliso ezifanayo, zinokubulala okanye zitshabalalise ingca esandula ukuntshula.Jonga iinkcukacha kwileyibhile yemveliso, kodwa imichiza yokutshabalalisa ukhula emagqabini amaninzi inokugalelwa kuphela kwingca entsha emva kokuba ichetywe kane.Ukuba umchiza wokutshabalalisa ukhula ugalelwe ukhula phambi kokulukhula, kufuneka ulinde iiveki ezimbalwa emva kokugalela umchiza wokutshabalalisa ukhula phambi kokuba ekugqibeleni uhlwayele imbewu yengca.Jonga ileyibhile yemveliso kwizithintelo.
Kwingca esele ikhulile ngaphandle kokutyala kakhulu, ungasebenzisa indibaniselwano yemveliso equlathe i-2,4-D ukubulala ukhula lwamagqabi abanzi njengeplantain, igalikhi yasendle, kunye nedandelion.
Ngolwazi oluthe vetshe malunga nengca kunye nokhathalelo lomhlaba, kunye nohlaziyo lwekhosi eyandisiweyo ezayo, kunye nokuphumelela imbewu yemifuno yasimahla kwisitiya sakho sasentwasahlobo, nceda undwendwele www.facebook.com/BooneHortNews okanye www.twitter.com/BooneHortNews.
