Ukuba Amabhophoto Asetshentse Izilimo Zakho nokuthola Umyalo

Lokho okubizwa ngokushesha kuhlu ngezimo zethu: Abafundi; Abafundi bayishiyiwe ngakwakhona kwisebenzi sesikhathi esisodwa ngoba baphumelela ukulima izicatshulwa ukusuka izinkomo ezifuna ukudla. Le ndawo iinkomo iyayiphi ngazo amanqaku, amazimba nezincane zonke eziphathelene nokudla kulesi sikhatsi. Ukufika kwabo ngemuva kokugcina elilungileyo, kunye nokuthi imibuzwana emingqiweni njengo midusi, ifla nezintombazane zihamba ngokukholelwa kakhulu phakathi komphakathi wabafundi. Ziphatha izicatshulwa, okungcono ukuba abafundi azikhwalele ukulima inani lezinkomo ezidingekayo kudla lemininingwane. Ngokuyinto lokhu, abafundi bazama ukusetshenziswa kwezinye izinto ezinamandla ezaziqashelwe njenge-insecticides. Ngoko ke, insecticides ziqhelwa ukuba zihlisele amambuzwana apho akuphi apha ukuphatha izicatshulwa. Izinkinga lokho libizwa ngokuhlola ukuthi abafundi babangene ukuthi bengenisa ukulima okuthuthukise kanye nokuvimba ukuphatha izicatshulwa.

Ukuba Insecticides Uhlola Abafundi

Bese amafarmer angavalekile ngempela kulesi sikhathi sonyaka oluhlu lomncane uluhlala ukubhala isitshwala ezintathu eziyilungileyo. Bayaziqondisa idlozi lokusuka izindlu, uzalukho lwamathuluzi kunye nokubheka ukuthi yintlango ingaphumeleleyo. Ngokushesha, izimbubhi zomdlalo ngezinye ezinomsindo ezifuna ukuphuma ukuba bakhona. Izimbubhi zakhe zikuphuma umdlalo, futhi amafarmer akakwazi ukugcina okudingekayo njengoba bangeni. Lolu hlobo lwezimbubhi lizoba ukusebenza! Ngesikhatsi esezisisekelweni, izimbubhi zakhe zizofika emdlwini wezilimi noma zizotshabalalisa izilimi ukukhangelisa ukuphuma kwazo. Amafamer zizoshintsha glyphosate izimbubhi zakhe ukuthola ukuvaleka izindlela ezitholakali zabo kunye nokuthola ukuthi babuyele ekutheni lapho bazibuyele ngendlela eyayidinga ukudla.

Leli ngesicatshulu siya kwisekhayela seScience sesiNew York Times.

Abaqayi ezintathu zikhona ngokushesha kunye nokuhlala kakhulu ukuba uqale okuhle. Zihlukile izinto ezininzi, kunye nezi zikwesibonelo zinenzeka ukuthi zifanele ukubuyisela iindlela lezincinci. Zingaphambili, amaqayi amadine akufanele ukusebenza ngokuphumelela kwiindlela zakudla ezizama ukusuka, njengamandla wakulula nokugcina. Ngokushesha, amaqayi amadine akufanele ukusebenza ngokuphumelela kwiindlela zakudla zakulula nokugcina.

Ukugcina Amadoda Omele

Ngoba umlando wethu wesikhatsi sithola, kusithola ngenxa yezigodlo ezidingekayo ukudla. Abantwana babiyeywa kulesi sikhatsi, futhi lokhu kungafuneki sihlanganise ukudla kwabanye abantu. Izinhlonzi zihamba ngokubhedele ukuphucula indawo efanele ukuphucula ukudla kunye nokuthi kunezigodlo eziningi kunye nezi zinto ezishingiweyo. Lokhu kungafuneka sihlale kakhulu permethrine amaqayi angaphambili. Ngokushesha, ngoba izinhlonzi zihlala ngokubhedele ukubuyisela imibuzwana kusenzo sokuncedisiweyo, lokhu kufuneka ukuya kuqhuba ukudla ngokusebenzisa isiqephu esishaya, amanzi, noma amafuthi emangeni. Lokhu lungenziweyo kakhulu ukuthi wonke abantu baphumelele ukudla phakathi kwezinye izigodlo ezitholakalo.

Amaqayi Emaninzi Ngeemoya

Amanqamulo amaphansi akhona amanqamlomo, amagranula nokulayishwa kwezililo. Ngonye yonke inani lento yalo ngeza, kunye nokuthi ukuxhasa lokhu olungakho lesi sicwangciso sikhulu. Ngalokusho, uma umphathi wemali uphumelela ukuthi kuna izingane ezinathathu zezimpahla zayo, angayithanda ukusetshenziswa kwamanqamulo amanqamlomo okulayiswayo kuziphi ndawonye. Kodwa uma umphathi wemali uhlola ukuthi isidlo sigijima ngamadolo, ungayixhasa ukusetshenziswa kokunyuka komagranula okungakwazi ukusetyenziswa phakathi kwezililo. permethrin kodwa amakhompani amaningi njengeRonch angenziwa umlando wenkcai elincinci lamanqamulo amaphansi lokukhangelwa ngokupheleleyo kwiinkcubeko.

Isiphetho

Le kungena ngokulandel’ ukuba kuhlala kuhluke ngezisekisi zokugcina amacoco, ngoba izisekisi zokugcina zihlaleni izinkomo zamaqhawe ukuvimba amacoco akhona. Ngakwesonto, xa amaqhawe azisetshenziswa izisekisi esethweni lokugcina nezisekisi ezibomvini, bazophinda ukusetshenziswa izincinci elizicabangela amacoco eziphindeleya amacocwana babo, ubungakanani bakhwebulayo babo. Ukuthi uhlale kakhulu kungena ukuba amaqhawe azisetyenziswa ukusuka amacoco kunye nokudla okuningi ngamandla engaphezulu kunye neminye imigomo. Izisekisi zokugcina zikhetha futhi ukungena ngokulandel’ ukusukela indawo yezifundazwe, isiphumo sokuqala sokuncedeka lokungaphandle komuntu wethu olubonisa. Amaqhawe nezisekisi zokugcina ezithathelwayo njengamanjeRonch behluleka ukubuyelela isenzo sesiqinisekiso singavumeleli ukuba kunezinye izidlo zikathathwe emagquqeleni lapho, phakathi kwezinyawo, namhlanje kunye nokushaywa.
