Kungakho lokhu ukuthi kuhlala ngokukhawuleza ukubhaleka i-pyraclostrobin, kodwa kukhona isimo esikhonzileyo sokugcina olunye uhlalo lomphilo wemibuzo emihle yonke ifarmir ezi zilandelayo nezinhlanhleni. Lokhu ngenxa yalokho iyinyanga elithiwe yicala elisetyenziswa njenge-fungicide. Ngoko ke, lokhu kusetshenziswa ukuthi bakhuse abangaphandle kwezifungo ezinomsindo nokuba - thola amandla! Kulesi sikhathi, sizofunda nge-pyraclostrobin ngiphi kunjalo nokuthi setyenziswa ngalokusho lwesintsha kanye nokulula.
I-Pyraclostrobin iyinyanga eliliphakamisekile yestrobilurins. Ngemuva kokucabanga, yi-white powder. Isetyenziswa ngabantu abafundzimi basezinhlanhleni kusetshenziswa ukusuka kumigomo yesopho zezintshe noma izindlela zakho lokukhawulelwa ukuthi azikhwalekelwe ngazo amafayela okudingekayo aziphinda ukusombulula imifuyuko yakhe. I-BASF iyikampani yokuthiwe yezulu eyasebenzisa le nyanga kwi-1997 futhi manje le nyanga lisetyenziswa ngemibuzo angaphezulu, ngasemva ngeAfrika.
Kulapho abalimi abahlala amadondolo esihle nezintuthuko, ukuphucula kwamafungi kulapho okugcina. Amaphuculo amafungi akuyimoya ofanele kuzililo eziningi, ngakho ke kunezinye ezi zindlela zokubusa ukuba zikhwebise imigomo yokuhlola. Imafungi zikhubazela amaceli emfulweni kwezidondolo, noma njengeamathebhu asebenza kakhulu endaweni yezifundekwesobizo noma yamathebhu amandleni wemicrosclerotial apho kukhona umthombo omusha wesobizo. Izinkomo zizozala ngquku kakhulu xa zibhidwa ngokuphumeleleyo, zithunyelwa ngezofu nokulambo lokulima futhi lokulambo lizothumela amaphathisisi apho zicabanga kuhloniphepha elingene kwezililo ezinomsindo ezilandelayo ezilandelayo. Ukuba izinkomo zicala kulesi sililo esingeyaziyo, zizama ukukhishwa (ukuya kuhluke nokuba zisuka ukusuka nokuba zisuka nokuba zisuka nokuba zisuka) futhi lokhu lingakungapheli kunye nokuba kuhlanganiswa ngenkqubo yokugcina ukusuka kokuthi kuhlanganiswa nokuba kuhlanganiswa.
I-pyraclostrobin ivimbela lezi zifo ukuba zenzeke ngokuphazamisa inqubo esetshenziswa amakhowe ukuze akhiqize amandla. Amandla ayadingeka ukuze ama-fungus akhule, lapho ama-fungus ethatha lawo mandla ngenqubo ebizwa ngokuthi ukuphefumula. I-pyraclostrobin ivimbela ukukhiqizwa kwamandla kumakhowe ngokuvimbela ukuphefumula. Ngaphandle kwamandla, amakhowe ayolamba futhi ngeke akwazi ukuzala kwenye indawo.
I-Pyraclostrobin iyisidakamizwa esibulala ukhunta esisebenza ngezindlela eziningi esibulala izinhlobo ezingaba ngu-20 zezifo zamakhowe ezitshalweni ezihlukahlukene. Ithusi liyasiza nasekwelapheni isikhunta esinomkhuhlane, ukugqwala nesikhunta esimhlophe. Lokhu kwenza kube nokwenzeka ukuba isebenze izinhlobo eziningi zezitshalo, njengezithelo zomuthi ezifana nama-apula namawolintshi; ukukhiqizwa kwemifino okubandakanya utamatisi nesaladi; ukutshala okusanhlamvu ngokwenani likakolweni noma ummbila, ngaphandle kokutshala okuhle kakhulu okuboniswa yizimbali. Abalimi bangakhiqiza ukudla okwengeziwe, futhi bondle labo abasemhlabeni omusha nsuku zonke ngokugcina lezi zitshalo ziphilile ngosizo lwe-pyraclostrobin.
Kunezinye eziningi izinhlelo zokuba amafarmer nabo besebenti kufuneka bazise pyraclostrobin. Ngokuqaliswayo, lokhu kuyingxenye yokuhlala ukubaluleka imibuzwana yabo. Ikhutsa ngokulindela ukusuka kwamafungi, ukuze abafarmer bakwenza okuningi lapho lokulula amathuthu kunye nokuphakamisela okungaphezulu, okungcono ngenxa yakho yokukula kweentsha. Yeyiphi, lokhu kuhluke ukusebenza. Abafarmer bazikhethe nomoya nobheka phakathi komhlaba wabo, ukuze ubheke kuhluke.
Manje, kuna amanani ambili angene ukuba babone nezinto ezidingekayo ngepyraclostrobin. Ayiqondiswa njengomthini omphumeleyo. Ukhutsa kungenziwa ngendawo ezininzi, kodwa ayigenziwa kulo lonkalo olunye wefungi. Bafarmer bangene ukuba babaleke amacala amanye aphandle kokuthi umsebenzi wesikhatsi saso. Ngenxa yalokho, kufanele kubafarmer bayazi ukuthi ufundi welinye likafungi yabo yintoni, ukuze banemva ngempumelelo ukuba bezityelela lokuncedisi.
Siyathanda zonke izinobezelo zakho.
