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 ukumbozwa okuhle emaqabungeni 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 yokugcina yomugqa wakho wokuhlola, futhi qiniseka ukuthi wenza ububanzi bomugqa wokuhlola okungenani ubungako besihloko 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 kokungu-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, izimbungulu ezinukayo, amabhungane amaqabunga kabhontshisi noma amabhungane aseJapane, ukungezwa kwesibulala-zinambuzane 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.
