Ngesikhathi uChris Schlegel eqala ukusebenza e-DS Cole, enye yezindawo zokugcina izithombo ezinkulu zezentengiselwano eNew Hampshire, isu lokulawula izinambuzane lalilula: fafaza yonke into ngesibulala-zinambuzane ngokushesha nje lapho kuvela izimpawu zokuqala zokutheleleka kwezinambuzane, bese uphinda njalo ngeviki.
UChris Schlegel, isazi sezolimo e-DS Cole, uthe ukulawulwa kwezinto eziphilayo kuthathe indawo yezibulala-zinambuzane zamakhemikhali njengomzila wokuqala wokuzivikela ezilokazaneni.
Leli cebo lashiywa futhi lathathelwa indawo yindlela ehlukile. Njengengxenye yale ndlela, uSchlegel nozakwabo banciphisa ukuvama kanye nenani lezindlela zokulawula amakhemikhali ezisetshenziswayo, ngisho nalapho zisetshenziswa. Abasasebenzisi izibulala-zinambuzane, kodwa kunalokho basebenzisa ngokuyinhloko lokho okubizwa ngokuthi “ukulawula kwezinto eziphilayo,” okusebenzisa izinqubo zemvelo ukulwa nezinambuzane.
Ezolimo ezigcina izitshalo eziluhlaza, ukulawulwa kwezinto eziphilayo kufezwa ngokuyinhloko ngokusebenzisa izinambuzane ezidla ezinye izilwane, ezingenabungozi ezitshalweni ngaphandle kwezilwane ezidlayo. Abalimi abaningi, njengo-DS Cole, basebenzisa ukulawulwa kwezinto eziphilayo ukunciphisa kakhulu ukusetshenziswa kwezibulala-zinambuzane.
Ubuchwepheshe obusha bonke bunamaphayona abo, kodwa abalimi abaningi baseNew Hampshire basathembele ezibulala-zinambuzane njengendlela yabo yokulawula izinambuzane nezifo. UJonathan Eba, uchwepheshe wasensimini e-University of New Hampshire Extension Center, kanye nozakwabo, okuhlanganisa u-Amber Venchesi-Wahl no-Amy Papineau, basebenza ukwenza ukushintshela ekulawulweni kwezinto eziphilayo kube lula futhi kuphumelele kakhudlwana.
"Ngenkathi nginikeza usizo lobuchwepheshe oluqondile kubalimi bezindlu ezigcina izitshalo kulo lonke izwe, kancane kancane ngaqaphela ukuthi badinga imiyalelo ecacile, yesinyathelo ngesinyathelo," kusho u-Eba, omunye wamalungu eqembu esiza abalimi abanjengo-DS Cole. "Ngakho ngakha ikhithi yokuqalisa yokulawula izinto eziphilayo. Luhlelo olungasiza abantu ukuthi baqale, bese beluhlela ngokwezidingo zabo ezithile eminyakeni elandelayo."
Ikhithi yokuqala yokulawula izinto eziphilayo iqukethe ulwazi ngezinto eziphilayo ezithile abalimi abangazisebenzisa, kanye namasu okusebenzisa ajwayelekile okuhlasela izinambuzane. Indlela ye-Eba idinga abalimi ukuthi baqaphe njalo umsebenzi wezinambuzane endlini eluhlaza okotshani—isibonelo, besebenzisa amakhadi aphuzi anamathelayo ukuze babambe izimpukane ezihamba phakathi kwezitshalo—futhi banqume isikhathi sokukhishwa kwezinambuzane ezidla ezinye.
Ukusetshenziswa kwezibulala-zinambuzane zamakhemikhali kungase kudingeke, yize ukuvama kwazo kanye nomthamo wazo kuzoncishiswa.
“Angazi muntu otshala izitshalo zokuhlobisa ngaphandle kokusebenzisa izibulala-zinambuzane,” kusho u-Eba, “kodwa ukulawulwa kwezinto eziphilayo kunciphisa kakhulu inani lezibulala-zinambuzane ezisetshenziswayo.”
Ngo-2008, uSchlegel waqala ukuzama ukulawula izinto eziphilayo e-DS Cole. Wakhipha izibungu ezazidla ama-thrip, ezazilimaza ama-gerbera. La ma-thrip aqala ukumelana nezibulala-zinambuzane zamakhemikhali, futhi ngisho nokufutha kwamasonto onke kwehluleka ukuwalawula. Ukuhlolwa kwanda ngokushesha ukuze kulawulwe izimpukane ezimhlophe, ezazilimaza izitshalo ze-poinsettia. Eminyakeni eyalandela, u-DS Cole waqala ukutshala amakhambi ezitsheni, futhi ukufika kwezitshalo ezidliwayo kwenza ukunciphisa ukusetshenziswa kwezibulala-zinambuzane kwaba yinto ebaluleke kakhulu.
USchlegel uthe ukulawulwa kwezinto eziphilayo okwamanje kuyindlela yokuqala yokuzivikela yenhlangano ezilonakalweni, futhi ukulawulwa kwamakhemikhali kuzosetshenziswa kuphela uma kukhona ukuqubuka kwezinambuzane futhi kungekho zitha zemvelo ezitholakalayo kwezentengiselwano ezitholakalayo.
USchlegel uthe ukulawulwa kwezinto eziphilayo kunezinzuzo eziningi. Okokuqala nokubaluleke kakhulu, kuphephile kubasebenzi abangu-80 be-greenhouse kanye nemvelo. Ezinye izinzuzo zifaka phakathi iqiniso lokuthi izitshalo eziningi ezikhuliswe yi-DS Cole zithengwa abanye abalimi abangafuni izitshalo eziphathwe ngezibulala-zinambuzane ziphazamise amasu abo okulawula izinto eziphilayo. Ekugcineni, ngemva kokunciphisa ukusetshenziswa kwezibulala-zinambuzane, baqala ukuthola izinambuzane zendawo ezicupheni ezinamathelayo eziphuzi. Lezi zinambuzane ezivelela ngokuzenzekelayo, ezisetshenziswa ekulawulweni kwezinto eziphilayo, zingena ngamafasitela avulekile, into ababengenakuyenza enkathini yokusetshenziswa kwezibulala-zinambuzane zamakhemikhali okusabalele.
Kuthiwani ngezindleko? Ingabe uDS Cole usebenzisa imali eningi ekulawuleni izinto eziphilayo kunasezindleleni zokufutha zendabuko? USchlegel ukholelwa ukuthi asikho isidingo sokubala lezi zibalo.
UChris Schlegel, isazi sezolimo e-DS Cole, uthe amakhadi aphuzi anamathelayo abekwa kuyo yonke indlu eluhlaza ukuze kuqashwe izinambuzane ezingafuneki.
"Ngicabanga ukuthi into ebaluleke kakhulu kithi nakwabanye abalimi abaningi ukuthi, uma sibheka indawo ezungezile, ukuphepha kwabasebenzi bethu, izinyosi, njalo njalo, zonke lezi zinto ziqinisekisa umzamo," kusho uSchlegel. "Le ndlela ibe yimpumelelo enkulu. Sisabhekana nezinambuzane, kodwa singazilawula ngempumelelo enkulu. Uma ungakaze usebenzise amakhemikhali amaningi ngaphambili, ukulawula izinambuzane kulula kakhulu ngoba izinambuzane azikakakhiqizi ukumelana nazo."
USchlegel uthe umnyango wokwandisa ungumlingani othembekile ka-DS Cole ekwandiseni ukusetshenziswa kwezindlela zokulawula izinambuzane eziphilayo. Ochwepheshe bokuphathwa kwezinambuzane abahlanganisiwe basiza inkampani ekuthuthukisweni kwamasu okuhlonza izinambuzane nokulawula, futhi bahlela nama-webinar anyanga zonke kanye nama-seminar okuphathwa kwezinambuzane mathupha. U-DS Cole uvumile ukusingatha enye iseminari enjalo ngo-Okthoba 2025.
“Sithole usizo olukhulu eNyuvesi yaseNew Hampshire, futhi nabo babambisene nabantu abaningi abanolwazi,” kusho uSchlegel.
"Enye yemigomo yami ukuveza ukuthi inani lezibulala-zinambuzane ezisetshenziswa ezitshalweni zokuhlobisa eNew Hampshire linciphile ngenxa yokulawulwa kwezinambuzane eziphilayo," kusho u-Eba.
Uma izindawo zokugcina izithombo zaseNew Hampshire zingasebenzisa njalo izindlela zokulawula izinambuzane eziphilayo esikhundleni sezibulala-zinambuzane esikhathini esizayo, la mabhizinisi azokwazi ukukhiqiza imikhiqizo enempilo, agcine abasebenzi bawo bephephile, futhi angase azuze imvelo.
