Ukuqapha kuthuthukisa ukulawulwa kwezinambuzane ze-potato tuber

I-Potato tuber moth ingaba yiphupho elibi kumkhiqizi wamazambane. Ngenhlanhla, uhlelo lokuqapha olusebenza kahle kakhulu lwe-InteliGro alugcini nje ngokusiza ekulawuleni lesi sinambuzane ngempumelelo kodwa luvumela abakhiqizi ukuthi baphathe izingozi futhi banciphise izindleko zokufaka ngokuhamba kwesikhathi.

Ngaphandle kwemikhiqizo yokulawula izinambuzane, bekungeke kwenzeke ukukhiqiza amazambane anele ukuhlangabezana nesidingo sabathengi. Ngokwesiko, abakhiqizi bamazambane balandela uhlelo oluqinile lokufafaza ukuze bavikele izitshalo zabo. Le ndlela ibalulekile, ikakhulukazi ukuqinisekisa ukuphathwa kwezifo okuphumelelayo.

Kodwa-ke, ngezinambuzane ezifana ne-potato tuber moth, indlela ebalwe kakhudlwana ingenzeka. Nakuba kunezinketho eziningana ezibhalisiwe zokulawula ngempumelelo i-potato tuber moth, imifantu iqala ukuvela esivikelo sezinye zezithako ezisebenzayo ezitholakalayo. Uma isu elifanele futhi imikhiqizo uma zingasetshenziswa, i-potato tuber moth ingabhubhisa isivuno samazambane sonke.

Ngenxa yezindleko zokukhiqiza ezikhula njalo, abakhiqizi abakwazi ukukhokhela iphesenti elikhulu lesitshalo ukuba lenqatshwe noma lehliswe ngenxa yomonakalo wezinambuzane. Izigidi zamarandi zisengozini.

Benalokhu engqondweni, i-InteliGro noStef Stephan baseStephan & Seun Potatoes bahlangene ukuze baqalise iphrojekthi yokuqapha amazambane yesikhathi eside ngo-2016. Ngaphansi kobuholi buka-André Erasmus, uchwepheshe wezobuchwepheshe bamazambane e-InteliGro, le phrojekthi isithole umfutho omkhulu futhi okwamanje iyingxenye ebalulekile yesevisi kanye nokusekelwa kokwenza izinqumo okunikezwa yi-InteliGro esifundeni sokukhiqizwa kwamazambane eSandveld.

U-André Erasmus:

"Ukuqapha sekuvele kuwumkhuba osuvele ukhona embonini yezithelo ezibolayo kanye nezithelo ezisawolintshi. Kodwa-ke, kungasetshenziswa ngempumelelo nakwezinye izitshalo, njengamazambane, njengoba kubeka isisekelo sokwenza izinqumo eziphumelelayo kanye nezixazululo eziqhubekayo."

Ukuqapha kuwukubambisana phakathi kwemvelo nezolimo. Ama-pheromone akhishwa yizimbungulu zesifazane ukuze adonsele abesilisa ukuze bahlangane akhiqizwa emalabhorethri futhi apakishwa ngama-ampule. Ama-ampule afakwa ezicuphweni futhi, njengoba ezama ukufinyelela emithonjeni yama-pheromone, izimbungulu zesilisa zibanjwa ezicuphweni. Umqaphi oqeqeshiwe ubala izimbungulu kanye ngesonto futhi ulwazi lusetshenziselwa ukuhlela izitayela nokwenza izinqumo ezinolwazi ngokuphendula imibuzo efana nalokhu:

Ingabe inkathazo ikhona noma cha?

Ingabe izinombolo zisezingeni lapho kudingeka kuthathwe khona isinyathelo, noma cha?

Ingabe izinyathelo zamanje ziyaphumelela, noma kufanele kulungiswe izikhawu zokusetshenziswa, imithamo, kanye/noma imikhiqizo?

INingizimu Afrika inamahektha angaba ngu-60 000 akhiqizwa amazambane. Iphrojekthi yokuqapha izibonakalise kaningi emasimini okunisela aseSandveld futhi manje isikulungele ukusekela abalimi bamazambane kwezinye izingxenye zezwe.

UStef Stephan:

"UStephan & Seun Potatoes bathenge iphrojekthi yokuqapha ye-InteliGro kusukela ekuqaleni. Eminyakeni emine edlule, inani lokulinganisa kwangempela lisinike ukuzethemba okwengeziwe futhi izinhlelo zethu zokufutha zokuvimbela zamasonto onke seziqalile ukwenza indawo yezinhlelo zokufutha ezisekelwe ku-100% emiphumeleni yokuqapha yamasonto onke."

"Manje sisebenzisa amakhemikhali ambalwa kunangaphambili ukulawula i-potato tuber moth, ngoba ukuqapha kusifundise ukufafaza ngesikhathi esifanele futhi kuphela uma ingcindezi yezinambuzane iphezulu. Lesi sinyathelo se-InteliGro siyindaba yempumelelo enkulu futhi siyisinyathelo esiqonde endleleni efanele."

U-André Erasmus:

“Sesike sabona, izinkathi ezine eSandveld, ukuthi ukuqapha kunganezela inani ekuvuneni nasekhwalithini. Siyazi ukuthi kusiza kangakanani ekuphuculeni ukuphathwa kwezingozi kwabakhiqizi nokunciphisa izindleko zabo zokufaka ngenxa yokunciphisa ukusetshenziswa kwemikhiqizo yokuvikela izitshalo. Sekuyisikhathi sokwabelana ngezinzuzo zokuphathwa kwezinambuzane okuhlanganisiwe nabakhiqizi kwezinye izindawo zokukhiqiza amazambane ezweni.”

Ngokusho kwe-Potatoes SA, isilinganiso esingu-6% samazambane afinyelela ezimakethe zemikhiqizo emisha eNingizimu Afrika sehliswa; lokhu kungaphezu kwamathani aqoqwa ezitolo ezithengisa ukudla emapulazini. Ukuqapha kanye namasu asebenza kahle kungasithuthukisa kakhulu lesi simo.

U-André Erasmus:

"Uma abakhiqizi bethatha izinyathelo ezifanele ngesikhathi esifanele nangezizathu ezifanele, bonga imali futhi bathuthukise amathuba abo okuvuna ngempumelelo. Ngaphezu kwalokho, sonke sisebenzisana ukuvikela imikhiqizo yokulawula izinambuzane etholakala kithi njengamanje."

Ngokubambisana ne-Cropwatch Africa, i-InteliGro iveza ipulatifomu yobuchwepheshe evumela ukuthi idatha yokuqapha yamasonto onke ithathwe futhi yabelwane ngayo ngogesi nabakhiqizi. Le pulatifomu idala nethuba lokuqoqwa kolwazi oluhlukahlukene, njengezithombe zesathelayithi, idatha yesimo sezulu, kanye nemininingwane yohlelo lokusebenza.

Ukubhekisela kulolu lwazi esikhathini esizayo kuzokwenza abakhiqizi bakwazi ukulungisa ukwenza izinqumo kanye nokugcina amarekhodi epulazini. I-InteliGro itshala imali ocwaningweni, ekuhlolweni, kanye nobuchwepheshe ukuze kube lula ukuqapha epulazini. André Erasmus:

"Siyazi ukuthi ukuphepha kokudla kuqala epulazini futhi kwakhelwe ekwenzeni izinqumo eziphumelelayo ezivikela izitshalo futhi ziqinisekise isivuno esihle kakhulu."
