Poyankhulana ndi a Syngenta's Herbicide US Technical Product Director, a Dane Bowers, poyankhulana za momwe ogulitsa ndi alimi ayenera kuyankha pa nyengo ya 2021, adatchula uthenga wake wopita kunyumba zaka zingapo zapitazi: Kulamulira kukana si munthu koma vuto laukadaulo.Nkhani zamakhalidwe.
"Kutengera luso laukadaulo, ndikuganiza kuti tili ndi lingaliro labwino kwambiri.Pali zovuta—musandilakwitse,” iye anavomereza motero, “koma tonsefe ndife zolengedwa zachizoloŵezi.Ngati zitithandiza, timakonda kuchita zomwezo. ”
Tikufuna kuganiza kuti 2021 ibweretsa kuchira m'mbali zonse, koma mpaka pamenepo, ino ndi nthawi yabwino kwambiri yomvetsetsa tanthauzo la kasamalidwe ka udzu.Anangowona namsongole akuthawa, koma osachuluka?Bowles anapereka lingaliro lakuti: “Imeneyo iyenera kukhala canary mumgodi wa malasha.”“Nthawi zonse mukawona zochitika zopulumukira kuthengo, muyenera kuganizira ngati ndakhala ndikugwiritsa ntchito pulogalamuyi kwa nthawi yayitali, komanso ngati sindinaphatikizepo malo ena okwanira papulogalamu yanga yophera udzu.Ndi zinthu zina ziti zomwe ndiyenera kuchita kuti ndipewe izi?Nthawi zambiri, m'chaka choyamba cha kukana, simukuganiza kuti muli ndi vuto, ndiyeno m'chaka choyamba Zinafika poipa m'zaka ziwiri.Pofika chaka chachitatu, zinali zoopsa.Zinalidi sitepe lakutsogolo.”
Pamndandanda wa malingaliro a Bowers pa nyengo yotsatira, ndi kuvomerezedwa ndi akatswiri ambiri azachuma, ndi: 1) kumvetsetsa zovuta zapadera za famu iliyonse, kuphatikiza mankhwala ophera udzu oyendetsa, ndi 2) kumvetsetsa kufunika koyamba kuyeretsa ndikusunga ukhondo.Izi zikutanthawuza kuthira mankhwala otsalira a herbicides amphamvu asanatulukire, ndiyeno kuthira mankhwala otsalira ophatikizika patatha masiku 14 mpaka 21.Mankhwala ophera udzu ayenera kuphatikiza malo angapo ogwira ntchito kuti achepetse chiopsezo cha udzu wosamva kubzala.
“Nthawi zambiri mbali yofunika kwambiri imakhala yovuta kwambiri.Ndipotu, takhala tikutsatira ndondomekoyi chifukwa mtengo ndi chilengedwe zidzatilepheretsa kupanga chisankho choyenera, "anatero Drake Copeland, Mtsogoleri wa FMC Technical Services ku Ohio, Michigan.
Wolfe adati: "Ndikuganiza poganizira za mankhwala ophera udzu, pulogalamu yabwino yotsalira yokhala ndi njira zingapo iyenera kukhala imodzi mwazosankha zanu zoyambirira.""Mukamayendetsa kumadzulo mu Ogasiti komanso koyambirira kwa Seputembala, zomwe mukuwona ndizosavuta.Otsala a anthuwa achepa, ndipo zotsalira zawonjezeka munyengoyi.Minda yawo ikuwoneka bwino kwambiri ndipo pafupifupi palibe madzi akuwunjikana.Anthu omwe amalumpha zotsalira, Minnesota, Iowa ndi Dakota ayenera kuti adawona chamba chambiri kumapeto kwachilimwe komanso koyambirira kwa autumn.
Bowers anagogomezera kufunika kogwiritsa ntchito mankhwala ophera udzu asanamere m’zinthu za dicamba, makamaka poganizira kuti Dr. Larry Steckel wa pa yunivesite ya Tennessee (L) poyamba anazindikira Palmer motsutsana ndi dicamba.
Steckel adalemba pa blog yake ya UT kuti akuyembekezera 2021, ndikofunikira kuti mulembetu zotsalira zomwe ndizovomerezeka kwa Palmer.Kuonjezera apo, ufulu uyenera kugwiritsidwa ntchito mwamsanga mutatha kugwiritsa ntchito dicamba kuthetsa kuthawa.
Steckel adanenanso kuti iyi ndi njira yachisanu yopha udzu yomwe Palmer adapanga ku Tennessee kuyambira 1994. kugwiritsa ntchito."
Pazogulitsa za Syngenta, ukadaulo wake wa Tavium Plus VaporGrip dicamba premix uli ndi S-alachlor, yomwe imapereka milungu itatu yotsalira kuposa dicamba yokha.Kampaniyo imanena kuti mankhwala ophera udzu akayamba kumera akagwiritsidwa ntchito mu mankhwala ophera udzu (monga Boundary 6.5 EC, BroadAxe XC kapena Prefix herbicides), "amapereka mwayi wabwino kwambiri wopereka mankhwala ophera udzu ku soya pakadutsa kamodzi".
"Ichi ndi chinthu champhamvu kwambiri, ngakhale mutakhala ndi mikhalidwe yotani, mutha kuletsa udzu pamaso pa soya, ndipo chimakupatsani mwayi wosinthika chifukwa sitiyika mazira onse m'paketi yotsalira.Mutha kubwereranso posachedwa kuti mudzagwiritse ntchito gulu la 15 la mankhwala ophera udzu, ndipo lilinso ndi kuchuluka kwa xylazine.Dr. Daniel Beran, Mtsogoleri wa Nufarm US Technical Services, adauza CropLife®.
"Titha kuthetsa kusatsimikizika kwina ndikukhazikitsa njira yotopetsa komanso yotsalira ndi kusinthasintha kwabwino.Ngati machitidwe asintha kapena zida zogwiritsira ntchito mbewuzo zili zoletsedwa kapena kusintha kwa nthawi yogwiritsira ntchito, ndiye kuti payenera kukhala zabwino. Pulogalamu yotsalira ya herbicide idzachepetsa kwambiri vuto la kusinthaku. "Iye adawonetsa kuti tsopano kwa Nufarm, ndizosangalatsa kukhala gawo lachitatu pagawo la dicamba ndi ukadaulo wa 2,4-D.Moment-imathandizira oimira makampani kuthandiza ogulitsa kuti adziwenso zoyambira.
Chinthu china chatsopano chopsereza mbewu chisanachitike ndi Reviton yomwe idakhazikitsidwa ndi Helm Agro ku United States.Ndi mankhwala a PPO inhibitor okhala ndi chinthu chatsopano cha Tergeo cha chimanga, thonje, soya ndi tirigu.M'mayesero opitilira 700 aku North America aku North America komanso maphunziro owongolera, Reviton yatsimikizira kuti "matsamba opitilira 50 amasamba ndi udzu (kuphatikiza mitundu yolimbana ndi ALS, triazine ndi glyphosate) ndiwothandiza kwambiri pakuwongolera magwiridwe antchito."
Chifukwa cha kutsika kwa mitengo ya zinthu, Copeland wawona mbewu zabwino (zomera zochulukirapo) ndi mikhalidwe yoyipa (kuchepetsa kugwiritsa ntchito mankhwala ophera udzu).
Ananenanso kuti: "Zotsalira za herbicide zomwe zikugwiritsidwa ntchito pambuyo pake ndiye chinsinsi chosungira udzu wotsalira wofunikira kuti mbewuyo isatsekedwe padenga," adawonjezeranso kuti, "Kuphatikiza apo, mankhwala otsalira a herbicides adzanyalanyazidwa pakugwiritsa ntchito kulikonse.Kuchulukitsa kubweza mbewu ku nkhokwe yanthaka kudzalola kuti ndalama zambiri zigwiritsidwe ntchito powonjezera zodutsa m'munda kuti zichotse zonyansazo. ”
Copeland adayitanitsa Yunivesite ya Purdue kuti ipange kafukufuku, yemwe adapeza kuti kuphatikizika kotsalira ndi njira yokhayo yochepetsera kasamalidwe ka nkhokwe ya mbewu ya chaka choyamba.Kuchiza popanda kugwiritsa ntchito mankhwala otsalira a herbicide okhala ndi malo angapo ochitirapo kanthu kunapangitsa kuti kuchuluke kwambiri kwa hemp yamadzi yodyedwa munkhokwe yambewu.Mosiyana ndi izi, njira yotsalira yotsalira kwa nthawi yayitali imagwiritsa ntchito zotsalira zotsalira kuti zichepetse kutentha kwa madzi Kufikira 34% (onani chithunzi pansipa).
Anati: "Zomwe zili ngati izi zitha kuthandiza ogulitsa ndi akatswiri azachuma kulankhula ndi alimi.""Atha kunena kuti, 'Ndikudziwa kuti nthawi ndizovuta, koma ngati tikufuna kukhala ndi tsogolo lokhazikika pafamu yanu, ndiye kuti sitiyenera kudula china, kaya fakitale kapena pamwamba, titha kuchepetsa zotsalira. mankhwala ophera udzu.’”
Monga momwe Dr. Bob Hartzler anafotokozera mu Blog ya Iowa State University Integrated Pest Management Blog kuti: “Chifukwa cha kufalikira kwa namsongole wosamva mankhwala a herbicide, njira zamakono zosamalira udzu zili pachiwopsezo Kuti mankhwala ophera udzu akhalebe olimba, zinthu ziwiri ziyenera kuchitika: 1) kutengera kasamalidwe ka udzu wophatikizika;2) kusintha cholinga cha kasamalidwe ka udzu kuchoka pa kuteteza zokolola kupita ku kuchepetsa kukula kwa nkhokwe za udzu.Chofunikira choyamba ndicho kusintha Khalidwe, chachiwiri chimafuna kusintha kaganizidwe.”
Kuphatikiza pakudumpha ndalama zotsalira zomwe zidachitika mwadzidzidzi, a Syngenta's Bowers adachenjezanso za mankhwala "abodza" kuti asunge ndalama.
Bowers adayambitsa mayeso okhazikika osungira omwe amachitidwa ndi Syngenta pazinthu wamba.Ngati zosakaniza zomwe zimagwira sizinapangidwe bwino, AI imatha kuukirana ndikuwononga mankhwala ophera udzu omwe alipo.Mlimi akamagwiritsa ntchito mankhwala omwe 80% yokha ya AI imagwira ntchito, sangakumane ndi zovuta zosakaniza, koma angagwiritsenso ntchito pa chiwerengero chochepa kusiyana ndi chizindikiro ndipo zotsatira za herbicidal ndizochepa kuposa momwe amayembekezera.
Bowers adanena kuti chitsanzo chapadera ndi chakuti anthu amakonda kugwiritsa ntchito njira yowonjezera, yomwe ndi kuphatikiza kwa AI S-metolachlor mu Dual II Magnum ndi AI mesotrione ku Callisto, yomwe Syngenta ingapereke Mitundu yambiri ya chimanga, monga Acuron.Mu premix ya mesotrione ndi S-metolachlor, "Ngati S-metolachlor sinapangidwe bwino, imanyoza mesotrione yomwe ilipo."
Bowers anawonjezera kuti: "Ndi lingaliro labwino kugwiritsa ntchito madola angapo patsogolo ndikusintha dongosolo la herbicides kuti lipereke zotsatira zabwino zopalira, kuti ma bushes pa ekala akhale abwinoko.Mitengo ikatsika, pangani zambiri Mabasi ambiri ndi makiyi anu.Sitingapulumutse njira yotukuka, chifukwa chake tiyenera kukhala osamala pakuwononga ndalama, koma tiyenera kuwonetsetsa kuti mukupeza mtengo wandalama zanu komanso kubweza kwa madola. ”
