Nginqume ukuzama ama-fungicides kubhontshisi wesoya okokuqala kulo nyaka.Ngazi kanjani ukuthi imuphi umuthi wokukhunta okufanele ngiwuzame, futhi kufanele ngiwusebenzise nini?Ngizokwazi kanjani uma kuyasiza?
Iphaneli yomeluleki wezitshalo oqinisekisiwe wase-Indiana ephendula lo mbuzo ihlanganisa u-Betsy Bower, Ceres Solutions, Lafayette;Jamie Bultemeier, isazi sezolimo namahlathi, i-A&L Great Lakes Lab, Fort Wayne;kanye no-Andy Like, umlimi no-CCA, eVincennes.
I-Bower: Bheka ukukhetha umkhiqizo wokubulala isikhunta onezinhlobo zesenzo ezixubile ezizofaka okungenani i-triazole ne-strobiluron.Okunye kufaka phakathi isithako esisha esisebenzayo i-SDHI.Khetha eyodwa enomsebenzi omuhle endaweni yamaqabunga e-frogeye.
Kunezikhathi ezintathu zesiteji zikabhontshisi wesoya abantu abaningi abaxoxa ngazo.Isikhathi ngasinye sinezinzuzo kanye nokubi.Ukube bengimusha ekusebenziseni isibulala-sikhunta sikabhontshisi wesoya, bengizokhomba isigaba sika-R3, lapho ama-pods eqala ukwakheka.Kulesi sigaba, uthola ukumboza okuhle emaqabunga amaningi ku-canopy.
Isicelo se-R4 sekwephuzile kakhulu emdlalweni kodwa singasebenza kakhulu uma sinonyaka wezifo ophansi.Kumuntu osebenzisa isibulali sikhunta okokuqala, ngicabanga ukuthi u-R2, oqhakaza ngokugcwele, kusesekuseni kakhulu ukuthi angafaka isibulala-sikhunta.
Okuwukuphela kwendlela yokwazi ukuthi isibulala-sikhunta siyathuthukisa isivuno ukufaka isiqeshana sokuhlola esingafakwanga ensimini.Ungayisebenzisi imigqa yokuphela komugqa wakho wokuhlola, futhi qiniseka ukuthi wenza ububanzi bomugqa wokuhlola okungenani bube usayizi wesihloko esihlanganisayo noma isiyingi esiyindilinga.
Lapho ukhetha ama-fungicides, gxila emikhiqizweni ehlinzeka ngokulawula izifo ohlangabezane nazo eminyakeni edlule lapho uhlola amasimu akho ngaphambi nangesikhathi sokugcwala okusanhlamvu.Uma lolo lwazi lungatholakali, bheka umkhiqizo obanzi onikeza izindlela ezingaphezu kweyodwa zesenzo.
I-Bultemeier: Ucwaningo lubonisa ukuthi imbuyiselo enkulu kakhulu ekutshalweni kwezimali uma kusetshenziswe isibulala-sikhunta esisodwa siphuma ekufakweni sekwephuzile ku-R2 kuya ku-R3 ngaphambi kwesikhathi.Qala ukuhlola amasimu kabhontshisi wesoya okungenani masonto onke kusukela ekuqhakazeni.Gxila esifweni nasekucindezelweni kwezinambuzane kanye nesigaba sokukhula ukuze uqinisekise isikhathi sokufaka isibulala-sikhunta esifanelekile.U-R3 uyaqashelwa uma kukhona i-pod engu-3/16-intshi kwelinye lamanodi amane aphezulu.Uma kuvela izifo ezifana nesikhunta esimhlophe noma ibala leqabunga lefrogeye, kungase kudingeke welaphe ngaphambi kuka-R3.Uma ukwelashwa kwenzeka ngaphambi kwe-R3, isicelo sesibili singadingeka kamuva ngesikhathi sokugcwaliswa okusanhlamvu.Uma ubona ama-aphid e-soybean abalulekile, ama-stinkbugs, amabhungane amaqabunga kabhontshisi noma amabhungane aseJapane, ukungezwa kwe-insecticide kuhlelo lokusebenza kungase kube kuhle.
Qiniseka ukuthi ushiya isheke elingalashiwe ukuze isivuno siqhathaniswe.
Qhubeka uhlola insimu ngemva kokufaka isicelo, ugxile ekwehlukeni kwengcindezi yesifo phakathi kwezingxenye ezilashiwe nezingakaphathwa.Ukuze ama-fungicides anikeze ukwanda kwesivuno, kufanele kube khona isifo ukuze isibulala-sikhunta silawule.Qhathanisa isivuno eceleni phakathi kokwelashwa nokungaphathwanga endaweni engaphezu kweyodwa yensimu.
Njengo: Ngokuvamile, ukufakwa kwesibulala-sikhunta esiseduze nesigaba sokukhula esingu-R3 kunikeza imiphumela engcono kakhulu yesivuno.Ukwazi isikhunta esingcono kakhulu ongasisebenzisa ngaphambi kokuqala kwesifo kungaba nzima.Ngokuhlangenwe nakho kwami, ama-fungicides anezinhlobo ezimbili zesenzo kanye nesilinganiso esiphezulu endaweni yamaqabunga e-frogeye asebenze kahle.Njengoba kuwunyaka wakho wokuqala nesibulala-sikhunta sikabhontshisi wesoya, ngingakushiya amapheshana ambalwa okuhlola noma ukuhlukanisa izinkambu ukuze nginqume ukusebenza kwemikhiqizo.
