I-PHILADELPHIA-FMC yethula isibulala-sikhunta esisha i-Xyway 3D, okuwukuphela kwesibulala-sikhunta sombila esisetshenziswa efektri ukuze sivikele izifo ngaphakathi kuyo yonke isizini kusukela ekuhlanyelweni kuya ekuvuneni.Ihlanganisa i-triazole fungicide fluorotriol kanye nokuguquguquka kwefekthri okuyingqayizivele.
Uma isetshenziswa enhlabathini, izithako ezisebenzayo ze-FMC zizomuncwa ngokushesha izimpande zesitshalo futhi zidluliselwe ngokushesha kuso sonke isitshalo ngaphambi kokuba isifo sivele, ngaleyo ndlela sinikeze ukuvikelwa kwezifo zakuqala, ezihlelekile futhi ezihlala isikhathi eside.Ikhono le-flutimofol lokuhamba ezitshalweni futhi liye ngaphandle emaqabunga asanda kunwetshwa afakazelwe, amanye ama-fungicides awakaze afakazelwe.
Uhlobo lwe-Xyway lomuthi wokukhunta luzoba semakethe ngesikhathi sokukhula sika-2021.Isibulala-sikhunta i-Xyway 3D yakhelwe ngokukhethekile isistimu yokufaka imisele ye-3RIVE 3D, evumela abalimi ukuthi bamboze umhlabathi omningi ngokugcwaliswa kabusha okumbalwa ngesikhathi esifushane.Ivikelwe yi-US Environmental Protection Agency (EPA) ngesifo samaqabunga, i-southern corn leaf blight, i-northern corn leaf blight, i- common rust, i-smut kanye ne-common smut.
Ngaphezu kwalokho, i-FMC inamanye amafomula adinga ukubhaliswa ne-EPA.Isibulala-sikhunta se-Xyway LFR, esakhelwe uhlelo lokufaka umanyolo owuketshezi.I-EPA yesibulala-sikhunta i-Xyway LFR kulindeleke ukuthi ibhaliswe engxenyeni yesine ka-2020. I-FMC ifuna ukubhaliswa kohlobo lwesifo esifanayo nesibulala-sikhunta i-Xyway 3D.
UBruce Stripling, i-FMC Regional Technical Service Manager, uthe: “Ukusetshenziswa kwezibulala-sikhunta zohlobo lwe-Xyway embonini kuzohlale kufinyelela izinga elifanayo lokuvikela izifo kanye nesivuno esikhulu njengoba kusetshenziswe ama-foliar fungicides ngesikhathi sokukhula kuka-R1.”“Isikhunta esisha sohlobo lwe-Xyway sivumela abalimi ukuthi basebenzise izibulala-sikhunta zezitshalo kalula nangempumelelo ukuze bathole ukuvikela izifo zesizini eyodwa.”
Ezifundweni nasezivivinyweni zasensimini kulo lonke elase-United States, isithako esisebenzayo se-flutriafol sohlobo lwe-Xyway fungicide sibonise ukusebenza kahle kwayo ngokumelene namabala amaqabunga ampunga, ukubola kwamaqabunga ommbila wasenyakatho kanye nokugqwala okuvamile.Ezinhlolweni eziningi, isilinganiso sezinga eliphezulu lokuqina kwesifo salezi zifo ezintathu sasiyingxenye yokulawula okungalashwanga, futhi ngokwezibalo lalilingana nokuncintisana kokwelashwa ngama-foliar.Kuzo zonke izifunda ezimaphakathi neziseningizimu, ucwaningo oluningi ekwenziweni kwesibulala-sikhunta somkhiqizo we-Xyway luveze isilinganiso esingu-13.7 bu/A ngaphezu kokulawula okungalashwanga, futhi isivuno sasifana nokwelashwa okuncintisanayo kwamakhasi angu-R1 kwe-Trivapro noma isibulala-sikhunta se-Headline AMP.Ezivivinyweni ezingama-42 zase-US ngo-2019, uma kuqhathaniswa namasheke angakacutshungulwa, ifomula ye-biocide yomkhiqizo we-Xyway ihlole u-8 bu/A owengeziwe ngokwesilinganiso.
“Siyibonile imiphumela yokusebenza engaguquki kusukela eLouisiana kuya eSouth Dakota kuzo zonke izinhlobo zenhlabathi nasemhlabeni owomile noma ukukhiqizwa okuniselwayo.Isithako esisebenzayo sizinzile emhlabathini futhi sihlala endaweni eyimpande, lapho Izitshalo zikwazi ukumunca ngokuqhubekayo kanye namanzi nemisoco.”Kusho Stripling.
Abalimi nabacwaningi baphinde babike ukuthi izimpande zombila ezilashwa nge-Xyway brand fungicide zinamandla.Ukuhlolwa kwe-FMC kubonise ukuthi ummbila olashwe nge-Xyway 3D fungicide unezimpande ezinde ngo-51%, indawo yempande emikhulu engu-32%, izimfoloko zezimpande ezingu-60% kanye nomthamo wezimpande ongaphezulu ngo-15% kunokuhlolwa okungakahlanzwa.Isimiso sezimpande esinamandla singakhuphula amandla ezitshalo okumunca amanzi nezakhamzimba, futhi andise isivuno.
Ucwaningo lwe-FMC nolwasenyuvesi lubonise ukuthi isithako esisebenzayo se-flutriafol ku-Xyway brand fungicide sinikeza isivikelo esibalulekile sesikhathi eside ezifweni eziningi ezibalulekile zamaqabunga ommbila lapho zisetshenziswa emhlabathini ngesikhathi sokutshala.UGail Stratman, oyiMenenja ye-FMC Regional Technical Service, uthe: “Ngemva kokufaka isicelo efektri, sibone izinsuku ezingaphezu kuka-120 zokuvikela izifo nokugcinwa kangcono kwemiphumela yezempilo eluhlaza kanye notshani.”“Lokhu ukuphela kwento engenzeka, ngoba i-flutimofin inezici Eziyingqayizivele, okuhlanganisa ukuthi ihlala kanjani eduze nezimpande, ihleleke kakhulu futhi ingakwazi ukuhambisa i-xylem.Ngaso sonke isikhathi lapho isitshalo sihlasela, sithatha amanzi, izakhi kanye nama-fluorotriphenols emhlabathini futhi siwahambisa ezicubu eziluhlaza ngokusebenzisa i-xylem , Ukuze kuvikelwe izitshalo emonakalweni wangaphakathi nangaphandle ngaphambi kwesifo.Lokhu kuhluke ngokuphelele kuma-foliar fungicides noma ezokwelapha imbewu.”
UKianna Wilson, umphathi womkhiqizo we-FMC American fungicide, uthe isikhathi esisele sezithako ezisebenzayo kuhlobo lwe-Xyway fungicide flutriafol kanye nokuvikelwa ngaphakathi ezifweni kungase kuyishintshe ngokuyisisekelo indlela abalimi abalawula ngayo izifo.Ujabule kakhulu ngokuthi i-FMC iletha lobu buchwepheshe obusha kubalimi.UWilson uthe: "I-FMC inefomula yemisele ehamba phambili emakethe kanye nobuchwepheshe bokusebenzisa inoveli, okusenza sibe nombono ohlukile wokuthi zisetshenziswa kanjani izithako ezisebenzayo nokuthi zibaluleke kangakanani kubalimi kunabakhiqizi abaningi."Qonda ukuthi abalimi bafuna ukuvikela izitshalo zabo ngosuku lokuqala ngaphambi kokuqala kwezifo.Ukuthola kabusha kanye nokwelashwa kungadla isikhathi futhi kuzwele isikhathi.Abalimi abaningi bazothola ukuthi ngokusebenzisa isibulala-sikhunta sohlobo lwe-Xyway efektri, futhi bathole iqabunga elifanayo Izinga elifanayo lokuvikela nokusabela kwesivuno njengesibulala-sikhunta likhanga kakhulu.”
I-Flutimofin iyilungu leqembu le-FRAC 3 futhi iyi-demethylation inhibitor (DMI).Kuyisisekelo semithi ebulala isikhunta ebalulekile ye-FMC foliar esetshenziswa ezitshalweni nasezitshalweni ezikhethekile.
Manje usukwazi ukufinyelela ngokugcwele izinsiza ze-inthanethi eziphelele, ezinamandla nezisebenziseka kalula ukuze ugweme ukulima.Umbono omuhle uzokhokha izikhathi ezingamakhulu ngokubhalisa kwakho.
