Mitengo yakwera katatu, ndipo ogulitsa ambiri sayembekezera zatsopano zatsopano pofika masika mawa
Karl Dirks, yemwe amalima mahekitala 1,000 ku Mount Joy, Pa., wakhala akumva za mitengo yamtengo wapatali ya glyphosate ndi glufosinate, koma sakuchita mantha nazo.
"Ndikuganiza kuti izidzikonza zokha," akutero.“Mitengo yokwera imakonda kukonza mitengo yokwera.Sindikukhudzidwa kwambiri panobe.Sindili m'gulu la nkhawa, kusamala pang'ono.Tidzazindikira. "
Chip Bowling sakhala ndi chiyembekezo, komabe.Posachedwapa adayesa kuyitanitsa glyphosate ndi wogulitsa mbewu wapafupi ndi R&D Cross, ndipo sanathe kumupatsa mtengo kapena tsiku lobweretsa.
Bowling, yemwe amalima mahekitala 275 a chimanga ndi mahekitala 1,250 a soya ku Newburg, Md anati: “Ndili ndi nkhawa kwambiri.Tikhoza kukhala ndi zokolola zochepa kwambiri zaka zingapo zilizonse, ndipo ngati tikhala ndi chilimwe chotentha ndi chouma, alimi ena angakhumudwe kwambiri.”
Mitengo ya glyphosate ndi glufosinate (Ufulu) yadutsa padenga popeza zinthu zakhala zotsika ndipo zikuyembekezeka kutsika mpaka masika akubwera.
Pali zifukwa zingapo zomwe zimayambitsa, akutero Dwight Lingenfelter, Katswiri wa udzu wowonjezera ku Penn State.Zimaphatikizanso zovuta zobwera chifukwa cha mliri wa COVID-19, kupeza phosphorous wokwanira kupanga glyphosate, zotengera ndi zosungirako zoyendera, komanso kutseka ndi kutsegulidwanso kwa chomera chachikulu cha Bayer Crop Sciences ku Louisiana chifukwa cha Mkuntho wa Ida.
"Ndi zinthu zambiri zomwe zikuchitika pakadali pano," akutero Lingenfelter.Glyphosate ya Generic yomwe idapita $12.50 pa galoni mu 2020, akuti, ikupita pakati pa $35 ndi $40 pa galoni.Glufosinate, yomwe ingagulidwe pakati pa $33 ndi $34 pa galoni, ikupita ku $80 pa galoni.Ngati muli ndi mwayi wopeza mankhwala ophera udzu, khalani okonzeka kudikirira.
"Pali malingaliro ena kuti ngati maoda afika, mwina osati mpaka Juni kapena nthawi yachilimwe.Kuchokera pamalingaliro otenthedwa, izi ndizodetsa nkhawa.Ndikuganiza kuti ndipamene tili pano, kukhala ndi anthu kuganiza mozama pazomwe tikuyenera kusunga, "atero a Lingenfelter, ndikuwonjezera kuti kuchepaku kungayambitse kuchepa kwa 2,4-D kapena clethodim, chomalizacho ndi njira yolimba yolamulira udzu.
Kuyembekezera mankhwala
Ed Snyder wa Snyder's Crop Service ku Mount Joy, Pa., Akuti alibe chidaliro kuti kampani yake idzakhala ndi glyphosate kubwera masika.
"Izi ndizomwe ndikuwuza makasitomala anga.Sizili ngati pali tsiku lomwe laperekedwa, "akutero Snyder.“Palibe malonjezo a kuchuluka kwa momwe tingapezere.Adziwa mtengo wake tikadzaupeza.”
Ngati glyphosate palibe, Snyder akuti makasitomala ake abwereranso kumankhwala ena odziwika bwino, monga Gramoxone.Nkhani yabwino, akutero, ndikuti ma premixes amtundu wokhala ndi glyphosate mkati mwake, monga Halex GT ya postemergence, akupezekabe ambiri.
Shawn Miller wa Melvin Weaver and Sons akuti mitengo ya mankhwala ophera udzu yakwera kwambiri, ndipo wakhala akukambirana ndi makasitomala za malire omwe ali okonzeka kulipirira malonda ndi momwe angatambasulire galoni la mankhwala ophera udzu akapeza.
Sakutenganso maoda a 2022 popeza chilichonse chimagulidwa pamtengo wotumizira, kusiyana kwakukulu kuyambira zaka zapitazo pomwe adakwanitsa kugulira zinthu pasadakhale.Komabe, ali ndi chidaliro kuti malonda adzakhalapo kamodzi kasupe akuzungulira ndipo akudutsa zala zake.
“Sitingagule mtengo wake chifukwa sitikudziwa kuti mitengo yake ndi yotani.Aliyense akudandaula nazo, "akutero Miller.
PULUMUTSA UTSITSI WAKO: Mavuto omwe akupitilirabe akupangitsa alimi kulephera kuyitanitsa glyphosate ndi glufosinate munthawi yake ya 2022.Chifukwa chake, sungani zomwe muli nazo ndikugwiritsa ntchito zochepa masika akubwera.
Kusunga zomwe mumapeza
Kwa alimi omwe ali ndi mwayi wopeza zokolola kumayambiriro kwa masika, Lingenfelter akuti aganizire za njira zosungira malonda, kapena kuyesa zinthu zina kuti adutse nyengo yoyambirira.M'malo mogwiritsa ntchito ma 32 ounces a Roundup Powermax, mwina mutsitse mpaka ma ola 22, akutero.Komanso, ngati zinthu zili ndi malire, kudziwa nthawi yoti mupondereze - kaya pamoto kapena pambewu - ingakhalenso vuto.
M'malo mobzala soya masentimita 30, mwina bwererani ku mainchesi 15 kuti muonjezere denga ndikupikisana ndi namsongole.Inde, nthawi zina kulima ndi njira yabwino, koma ganizirani zovuta zake - kukwera mtengo kwamafuta, kusefukira kwa nthaka, kuswa malo osalima kwa nthawi yayitali - musanadutse ndikung'amba pansi.
Scouting, Lingenfelter akuti, zikhalanso zofunika, monganso kuyembekezera kukhala ndi magawo abwino kwambiri.
Iye anati: “Chaka chamawa kapena ziwiri, tingakhale tikuwona minda yaudzu."Khalani okonzeka kuvomereza pafupifupi 70% kuletsa udzu m'malo mwa 90% kuletsa udzu."
Koma palinso zovuta pamalingaliro awa.Udzu wochulukira umapangitsa kuti zokolola zichepe, Lingenfelter akuti, ndipo udzu umakhala wovuta kuuwongolera.
"Pamene mukuchita ndi Palmer ndi waterhemp, 75% kulamulira udzu sikokwanira," akutero."Lambsquarter kapena red root pigweed, kuwongolera 75% kungakhale kokwanira.Mitundu ya namsongole ifotokozadi momwe ingakhalire yotayirira ndi kuletsa udzu. ”
Gary Snyder wa Nutrien, yemwe amagwira ntchito ndi alimi pafupifupi 150 kum'mwera chakum'mawa kwa Pennsylvania, akuti mankhwala aliwonse ophera udzu omwe apezeka - glyphosate kapena glufosinate - amagawidwa ndikupatsidwa supuni.
Iye wati alimi akuyenera kukulitsa phale lawo la mankhwala ophera udzu m’nyengo ya masika kuti zinthu zigwere msanga, choncho udzu sivuto lalikulu pakubzala.
Ngati simunasankhe chimanga chophatikizika, Snyder akuganiza zopeza mbewu yomwe ili ndi njira zabwino kwambiri zothanirana ndi udzu.
Iye anati: “Chinthu chachikulu kwambiri ndi mbewu yoyenera.“Mizirani msanga.Yang'anirani mbewuyo kuti udzu uthawe.Zogulitsa za m'ma 90s zikadalipo ndipo zitha kugwira ntchitoyi.Lingalirani chilichonse. ”
Bowling akuti akusunga zosankha zake zonse.Ngati mitengo ya zipangizo ipitilila kuphatikizirapo mankhwala ophera udzu, ndipo mitengo ya mbeu ikapanda kukwera, iye wati asintha maekala ochuluka ku soya kaamba koti kulima kwake sikudula, kapena mwina asintha maekala ochuluka kukhala kulima udzu.
Lingenfelter akuyembekeza kuti alimi samadikirira mpaka kumapeto kwa dzinja kapena masika kuti ayambe kulabadira nkhaniyi.
Iye anati: “Ndikukhulupirira kuti anthu akuona kuti ndi nkhani yaikulu."Ndikuwopa kuti pakhala anthu ambiri omwe angodzidzimuka pongoganiza kuti angathe, bwerani Marichi, pitani kwa wogulitsa wawo ndikuyitanitsa ndikunyamula mankhwala ophera udzu, kapena mankhwala, kunyumba tsikulo.Ndikuganiza kuti pakhala kudzutsidwa kwamwano kumlingo wina. ”
