1. Ukhula ngalunye lune-spectrum ethile yokulawula ukhula, kanti ezinye izinhlobo zokulawula ukhula zingaba zincane kakhulu. Isibonelo, i-dimethoate iyasebenza kakhulu ekulawuleni ukhula oluyimpuphu kanye nembewu ye-rapeseed yasendle, kodwa umphumela wokulawula ukhula oluyimpuphu awubonakali, noma mubi kakhulu.
2. Izindawo zasendaweni kufanele zikhethe imithi yokubulala ukhula esebenzayo ngokwezinhlobo zokhula ezivame kakhulu endaweni yakini. I-Caokuojing, i-Kuomie, i-Hekuojing, njll. ziyasebenza ngokumelene nokhula olunamaqabunga abanzi, kuyilapho i-metsulfuron-methyl kanye ne-chlorsulfuron-methyl (evinjelwe njengamanje) zinesikhathi eside kakhulu esisele futhi zinomthelela omkhulu kakhulu enhlabathini nasendaweni ezungezile. Uma utshani olunamaqabunga abanzi (izithombo) lutshalwe ngemva kokufakwa esikhundleni, kuzokwenzeka umonakalo omkhulu wezibulala-zinambuzane. Uma kunokhula oluningi otshanini, ukusebenzisa i-Caohejing, i-Helike, i-Hekejing, njll. kunemiphumela emihle.
3. Khetha imithi yokubulala ukhula efanelekile ngokwezinhlobo ezahlukene zotshani. Ngokwezindinganiso ezahlukene zokuhlukanisa, utshani lungahlukaniswa lube utshani olulodwa kanye notshani olunezinhlobo ezimbili, olufudumeleutshani bomhlabakanye notshani obuhlala ezindaweni ezibandayo, njll. Izinhlobo ezahlukene zotshani zinokumelana okuhlukile nemithi yokubulala ukhula. Sesivele sazi ukuthi uhlelo lokumelana nemithi yotshani obuvuthiwe kusukela kokukhulu kuya kokuncane yilolu: I-Zoysia> Utshani baseBermuda> Utshani Oluhlaza Okwesibhakabhaka> I-paspalum yolwandle> I-Ryegrass> I-fescue ende> Utshani obune-Bent. Isibonelo, ukusebenzisa i-Grass-Kuangjing ukulawula ukhula olunamaqabunga abanzi otshanini be-Gramineae kuphephile otshanini; ukusebenzisa i-Grass-Kuangjing ukwelapha utshani obunamaqabunga abanzi kuphephile otshanini; ukusebenzisa i-Grass-Kuangjing ukulawula ukhula lwe-Gramineae otshanini obunamaqabunga abanzi kuphephile otshanini; ukusebenzisa i-Grass-Kuangjing ukulawula ukhula olunamaqabunga abanzi otshanini be-Gramineae kuphephile, futhi kungasusa nokhula oluhlukahlukene oluyingozi; I-Mesa-Kuang ingalawula i-Cyperus rotundus.
4. Utshani bunokumelana okuhlukile nemithi yokubulala ukhula ezigabeni ezahlukene zokukhula.Utshani obutshalwe kabushaUngasebenzisa ama-herbicides ngesikhathi sokuvuthwa kwawo kanye nezigaba zokukhula. Kuma-grass ahlwanyelwe ngqo, uma usebenzisa ama-herbicides ngaphambi kokutshala, isikhathi esisele kumele sicatshangelwe, kungenjalo sizothinta izinga lokuvela kwembewu yotshani. Ukusetshenziswa kwama-herbicides ekukhuculeni ukhula okuvaliwe ngaphambi kokutshala imbewu ngemva kokutshala utshani kudinga ukuphepha okuphezulu kwama-herbicides. Kuma-grass ahlwanyelwe ngqo ngemva kwesigaba samaqabunga ama-5, ama-herbicides engeziwe afanelekile.
5. Ukukhethwa kwemithi yokubulala ukhula yezigaba ezahlukene zokukhula kokhula nakho kubaluleke kakhulu. Ngaphambi kokuba ukhula lube namaqabunga ama-5, ukumelana kubuthakathaka, umthamo uncane futhi umphumela muhle. Ngemva kwamaqabunga ayi-7, umthamo uyanda, umphumela uyancipha, futhi isici sokuphepha setshani siyancipha; esigabeni sokukhula sekwephuzile kokhula, ikakhulukazi ngemva kokuba ukhula selubeke imbewu, umphumela wokubulala ukhula uba mncane nakakhulu.
6. Ezinye izinto: njengokukhukhuleka kwemithi yokubulala ukhula, umthelela kwezinye izimbali endaweni ezungezile; ukuthi ngabe izinsalela zemithi yokubulala ukhula zizothinta yini isivuno esilandelayo sezitshalo zasegadini; izidingo zokuvikela indawo ezungezile, njll. Ezindaweni lapho abantu, ikakhulukazi izingane, bevame ukudlala khona, njengezinkundla zegalofu, izinkundla zemidlalo, utshani bepaki, utshani obuluhlaza, njll., kufanele kusetshenziswe imithi yokubulala ukhula engenabo ubuthi, futhi inani lokufafaza imithi yokubulala ukhula kufanele libe lincane ngangokunokwenzeka.
