Izindaba zokuthi umquba ungase ungcoliswe izinsimbi ezinzima ezivela emanzini angcolile kanye nezibulala-khula eziyingozi ezithela emhlabathini azintsha. Ngo-2010, iNyuvesi yaseMaryland Extension yakhipha "Isaziso Somgadi! Qaphela umquba ongcoliswe ngama-herbicides kanye nomquba.” I-Ohio State University Extension ishicilele iphepha lamaqiniso (PDF) mayelana nesibulala-zinambuzane esisodwa esiqhubekayo esitholakala kumquba obulala utamatisi, ama-eggplant neminye imifino ye-nightshade, kanye nobhontshisi nobhekilanga.
Kodwa muva nje, kubonakala sengathi abalimi baqala ukunaka enye inkinga ehlobene nenhlabathi ekhiqizwa ngobuningi bezentengiselwano kanye nomquba: ukwethulwa kwezinambuzane nezifo engadini yakho noma indawo ekhulayo.
Akhona amaphutha? Chofoza kusixazululo sethu sezinambuzane ukuze ubuke izithombe, izincazelo kanye nohlu olugcwele lwemikhiqizo eco-friendly. Uma ihlasela izitshalo... uzoyithola lapha! Ihlanganisa yonke into kusuka kuma-aphid kuya kuma-whiteflies.
Ukutshala inhlabathi, kungakhathaliseki ukuthi kuza ezikhwameni noma ezimbizeni ezinempahla yokutshala oyithengayo, kuwukungcola okunamandla. Kwaziwa ngokwethula i-aphid yezimpande eyayingaziwa kangako ezindlini zokugcina izithombo nasezingadini ezweni lonke ngezinga elifana nobhubhane. Kwaziwa futhi ngokuthwala omiyane besikhunta.
Olunye uhlobo oludumile lwenhlabathi yobumba ludume kakhulu ngokuqukatha izinambuzane Ukusebenza namakhasimende Kunekhasi elibhekelele izikhalazo.
Ungathola futhi izikhalazo ku-inthanethi mayelana nenhlabathi enezinga eliphansi kanye nomquba ezitolo ezinkulu eziqukethe ipulasitiki nezinye izibi.
Kunzima ukulandelela ukusabalala kwezifo zezitshalo kanye nezifo zefungal ezindaweni zasengadini. Kodwa inhlabathi yokufaka imbiza isolwa kakhulu ngokubhebhetheka kwezifo, isikhunta kanye nesikhutha lapho isetshenziswa khona. Thenga kuphela ikhwalithi ehamba phambili kulabo obathembayo.
Ama-root aphid avame ukungena emhlabathini lapho kugxilwe khona izitshalo zasebhodweni. Lezi zintwala ziphuca izitshalo amandla namandla, okuholela ekuwohlokeni kwezithelo nokuqhakaza. Ukuthenga ama-clones nama-nursery kubalimi abathembekile, okungcono basekhaya ongababuza nxazonke kuyinzuzo enkulu. Gwema imikhiqizo yezingane ethengiswa ngezitolo ezinkulu kanye nezitolo ezinkulu zamabhokisi.
Ukuthenga amabhrendi athembekile emithonjeni ethembekile nakho kubalulekile lapho uthenga umquba nomquba. Noma yimuphi umquba owenziwe ngezicucu zotshani basedolobheni kanye nokunye udoti oluhlaza ungaqukatha izinsalela zokubulala ukhula. Idolobha laseSeattle lafunda isifundo esinzima emuva ngeminyaka yawo-1990 lapho umquba owenziwe ngemfucumfucu yasegcekeni egaywe kabusha uqala ukubulala izitshalo zemifino. Le nkinga yagcina iholele ekuvinjweni kokusetshenziswa kwe-clopyralid otshanini.
Manje enye i-herbicide ephikelelayo itholakala kumquba - i-aminopyralid. I-Aminopyralid isetshenziswa kakhulu ezindaweni ezinotshani nasemadlelweni ukubulala ukhula lwamaqabunga abanzi. Njenge-clopyralid, ihlasela izinhlobonhlobo zezitshalo zemifino enamahlamvu abanzi, okuhlanganisa uphizi, ubhontshisi notamatisi. Njenge-clopyralid, ingaqhubeka emhlabathini kanye nomquba izinyanga noma ngisho neminyaka (inqubo yokwenza umquba ayisheshi ukubola kwayo).
I-Aminopyralid, ekhiqizwa yi-Dow AgroSciences, itholakala emqubeni wobisi kanye nezinkomo. Lomquba usetshenziswa kakhulu emapulazini nasemasimini, kodwa futhi ugcina usebulongwe nasemvundisweni odayiselwa abalimi basekhaya.
Izinkinga ngesibulala-zinambuzane, ezaqala ukuvela ngo-2005, zaqala ukuvela eNgilandi ngo-2008. I-Dow ikumise okwesikhashana ukusetshenziswa kwesifutho kuze kube yilapho kukhishwa isexwayiso (isixhumanisi sisusiwe).
Uma ungeke ukwazi ukuthenga umquba nomhlabathi emithonjeni yemvelo, kuphephe kakhulu ukuzenzela owakho. Ngale ndlela uzokwazi kahle ukuthi kwenzekani nokuthi yini engekho. Ukuthula kwengqondo akukwazi ukuthengwa njalo.
Ngaphambilini
