Umbuzo: Ingabe kuphumelela kakhulu ukwelapha utshani ukuze kuvinjelwe inkalankala manje, noma kufanele silinde ukuthi ikhule ngaphambi kokuyibulala ngama-herbicides?Ngekwindla edlule, ngibeke phansi imithi yokubulala ukhula.Ingabe kwanele lokho?Ucabanga ukuthi i-verbena yasinda ebusika obunzima?Ingxenye yotshani bami isanda kuhlwanyelwa.
IMP: Isitshalo se-hawthorn owasitshala otshanini bakho ngonyaka odlule sesifile.Nokho, ngaphambi kokuba zife, eziningi zingase zikhiqize izinkulungwane zembewu, manje ezomila otshanini bakho emasontweni ambalwa ezayo.Indlela yokuvimbela ukuqhuma kwerayisi kusenesikhathi ukuxazulula inkinga, hhayi ukuzama ukubulala ukhula ngemva kokuba selusungule otshanini bakho.
Nakuba ikwindla kuyisikhathi esihle sokwelapha ukhula lwe-broadleaf ngama-herbicides, ayikho inzuzo enkulu ekusebenziseni imithi yokuvimbela i-verbena ekwindla, ngoba i-verbena iba minyaka yonke ehlobo futhi ihluma ekuqaleni kwentwasahlobo esikhundleni sekwindla.Lapho kufika amazinga okushisa abandayo ebusika, izitshalo ziyafa.Ngaphambi kokuba imbewu ye-verbena iqale ukuhluma futhi ikhule, kufanele kusetshenziswe isivikelo se-verbena (“pre-emergent herbicide”) kufanele sisetshenziswe.
Ezitshanini ezisanda kuhlwanyelwa, kufanele ukhethe futhi usebenzise izibulala-khula ngokucophelela ukuze uvimbele ukubulala noma ukulimaza utshani obutsha obutshalile.Phakathi no-March kuya phakathi no-April isikhathi esingcono kakhulu sokusebenzisa umzuliswano wokuqala wemithi yokubulala ukhula ngaphambi kokuhluma ukuze ulawule utshani be-horsetail.Lawa makhemikhali asetshenziswa ngaphambi kokuba imbewu yokhula iqhume.Bangakwazi ukuvimbela imbewu ye-horsetail ukuthi ingahluma noma ibulale izithombo ze-horsetail lapho ziqala ukuhluma.Qiniseka ukuthi umkhiqizo owuthengayo ungasetshenziswa ngokuphepha otshanini obusha obuqukethe izithako ezisebenzayo njenge-siduron (Tupersan).Lokhu kungasetshenziswa ngisho nangesikhathi sokutshala noma ngemva kokutshala entwasahlobo.Ingakwazi ukulawula utshani be-horsetail notshani be-foxtail.
Etshanini obuvuthiwe, ungakhetha izindlela eziningi zokulawula ukumila kwangaphambi kokuhluma kotshani behhashi, utshani be-foxtail nezimpaphe zehansi, okuhlanganisa i-befen+trifluralin (Ithimba), i-benzsulfone (Betasan, PreSan, Lescosan), ne-Austrian Sand pine (Ronstar), pendimethalin ( I-Weedgrass Control, Pre-M, Halts, Pendulum), dithiopyr (Dimension), Prodiamine (Barricade) kanye ne-bensulide + oxadiazon (foie gras/crab grass control).Enyakatho yeKentucky, lawa makhemikhali adinga ukusetshenziswa ngaphambi kuka-April 15. Landela ngemva kwamasonto ayisithupha futhi uyisebenzise ngokuphindaphindiwe ukuze welule ububanzi bokulawula kulo lonke ihlobo.Uma i-gooseweed iwukhula oluqondiswe kakhulu, sicela wenze isicelo sesibili cishe ngoMeyi 15.
Lapho utshani obutshaliwe, otshanini obusha noma emhlabathini obuzohlwanyelwa emasontweni ambalwa ezayo, ukulawula ukhula lwamaqabunga abanzi ngokuvamile akuyona inketho yangempela, njengoba imithi yokubulala ukhula eminingi izobulala ama-dandelion, i-clover, nokhova Utshani, ama-violets, i-ivy, njll. Iqukethe i-2,4-D noma imikhiqizo efanayo, ingaphinda ibulale noma ibhubhise utshani obusanda kumila.Hlola ilebula yomkhiqizo ukuze uthole imininingwane, kodwa imithi eminingi yokubulala ukhula ye-broadleaf ingasetshenziswa kuphela otshanini obusha ngemva kokuba isigundwe izikhathi ezine.Uma umuthi wokubulala ukhula ugcotshwa okhulani ngaphambi kokuwukhipha, kufanele ulinde amasonto ambalwa emva kokufaka umuthi ngaphambi kokuhlwanyela imbewu yotshani.Hlola ilebula yomkhiqizo ukuthola imikhawulo.
Etshanini obuvuthiwe ngaphandle kokuhlwanyela ngokweqile, ungasebenzisa umkhiqizo oyinhlanganisela oqukethe i-2,4-D ukubulala ukhula lwamaqabunga abanzi njenge-plantain, ugalikhi wasendle, nedandelion.
Ukuze uthole ulwazi olwengeziwe mayelana nokunakekelwa kotshani nokwakheka kwezwe, kanye nezibuyekezo zesifundo esandisiwe esizayo, kanye nokuwina imbewu yamahhala yemifino engadini yakho yasentwasahlobo, sicela uvakashele ku-www.facebook.com/BooneHortNews noma ku-www.twitter.com/BooneHortNews.
