Mitengo yakawedzera katatu, uye vatengesi vazhinji havatarisiri chigadzirwa chitsva pachirimo chinotevera
Karl Dirks, uyo anorima maeka chiuru muMount Joy, Pa., anga achinzwa nezvemitengo yepamusoro yeglyphosate neglufosinate, asi haasati ari kuvhunduka nazvo.
“Ndinofunga kuti ichazvigadzirisa,” anodaro.“Mitengo yakakwira inokonzeresa mitengo yakakwira.Handisati ndanyanya kunetseka.Handisati ndave muchikamu chekunetseka, zvishoma kungwarira.Tichazvigadzirisa."
Chip Bowling haina tariro zvakadaro, zvakadaro.Nguva pfupi yadarika akaedza kuisa odha yeglyphosate nemutengesi wembeu nembeu yemuno, R&D Cross, uye havana kukwanisa kumupa mutengo kana zuva rekutumira.
“Chokwadi ndinonetsekana,” anodaro Bowling, anorima maeka 275 echibage uye maheka 1 250 esoyabhinzi muNewburg, Md. “Kuno kuEast Coast, takanakidzwa negoho rakawedzerwa uye kurima kwakanaka kwazvo.Tinogona kuva negoho risiri pakati pemakore akati kuti, uye kana tiine zhizha rinopisa, rakaoma, zvinogona kurwadza vamwe varimi.”
Mitengo yeglyphosate uye glufosinate (Rusununguko) yapfuura nepamusoro pedenga sezvo zvekushandisa zvave zvakaderera uye zviri kufanotaura kuti zvichadzikira muchirimo chinotevera.
Zvinhu zvakawanda zvinokonzeresa, anodaro Dwight Lingenfelter, nyanzvi yekuwedzera masora nePenn State.Izvi zvinosanganisira nyaya dzinogara dziripo dzekutengesa kubva kuCOVID-19 denda, kuwana phosphorus yakakwana yakacherwa kugadzira glyphosate, mudziyo uye zvekutakura, uye kuvharwa nekuvhurwazve kwechirimwa chikuru cheBayer Crop Sayenzi muLouisiana nekuda kweDutu reDutu.
"Ingori musanganiswa wezvinhu zviri kuitika izvozvi," Lingenfelter anodaro.Generic glyphosate iyo yakaenda nemadhora gumi nemaviri pagaloni muna 2020, anodaro, yave kuenda pakati pemadhora makumi matatu nemashanu nemadhora makumi mana pagaloni.Glufosinate, inogona kutengwa pakati pemadhora makumi matatu nematatu nemadhora makumi matatu nemana pagaloni, yave kuenda nemari inodarika makumi masere emadhora pagaloni.Kana uine rombo rakanaka rekuti utore mushonga wesora uodharwe, gadzirira kumirira.
"Pane imwe pfungwa yekuti kana maodha akasvika, pamwe kwete kusvika June kana gare gare munguva yezhizha.Kubva pakuona kwekutsva, izvi zvinonetsa.Ini ndinofunga ndipo patiri pari zvino, kuita kuti vanhu vafunge kuburikidza nemaitiro ezvatinofanira kuchengetedza, "Lingenfelter anodaro, achiwedzera kuti kushomeka uku kunogona kukonzera kukanganisa kwekuwedzera kushomeka kwe2,4-D kana clethodim, iyo yekupedzisira iyo isarudzo yakasimba yekudzora uswa.
Kumirira chigadzirwa
Ed Snyder weSnyder's Crop Service muMount Joy, Pa., Anoti haana chivimbo chekuti kambani yake ichave neglyphosate muchirimo.
“Ndizvo zvandiri kuudza vatengi vangu.Hazvina kuita sekuti pane zuva rakapihwa, ”anodaro Snyder.“Hapana kuvimbiswa kuti tingawana zvakadii.Vachaziva kuti mutengo wacho ndewei kana tauwana.”
Kana glyphosate isipo, Snyder anoti vatengi vake vangangodzokera kune mimwe mishonga yakajairika, seGramoxone.Nhau dzakanaka, anodaro, ndezvokuti mazita-brand premixes ane glyphosate mavari, seHalex GT ye postemergence, achiri kuwanikwa zvakanyanya.
Shawn Miller weMelvin Weaver and Sons anoti mitengo yemishonga yesora yakwira zvakanyanya, uye anga achikurukura nevatengi nezve mukana wavanenge vachida kubhadhara chigadzirwa uye kuti vangatambanudza sei galoni remishonga kana vangoiwana.
Haatombotore maodha e2022 sezvo zvese zviri mutengo panzvimbo yekutumira, mutsauko mukuru kubva kumakore apfuura paakakwanisa kutenga zvinhu pachine nguva.Zvakadaro, ane chivimbo chekuti chigadzirwa chichave chiripo kamwe chitubu chinotenderera uye chiri kuyambuka zvigunwe zvake.
“Hatikwanise kuitengesa nekuti hatizive kuti mitengo yacho ndeipi.Munhu wese ari kusvotwa nazvo,” anodaro Miller.
CHENGEDZA MUPFUPI YAKO: Matambudziko arikuenderera mberi ezvekugovera ari kukonzera varimi kuti vatadze kuodha glyphosate uye glufosinate munguva yemwaka wekukura wa2022.Saka, chengetedza zvaunazvo uye shandisa zvishoma muchirimo chinotevera.
Kuchengetedza zvaunowana
Kune varimi vane rombo rakanaka rekuwana chigadzirwa kutanga kwechirimo, Lingenfelter anoti vafunge nezve nzira dzekuchengetedza chigadzirwa, kana kuedza zvimwe zvinhu kuti vapfuure mwaka wekutanga.Panzvimbo pekushandisa 32 ounces yeRoundup Powermax, pamwe idonhedze pasi kusvika makumi maviri nemaviri, anodaro.Zvakare, kana zvekushandisa zvakashomeka, kuona nguva yekupfapfaidza - kungave pakutsva kana muchirimwa - inogona kunge iri nyaya zvakare.
Panzvimbo pekudyara soya beans makumi matatu, pamwe dzokera kumashure masendimita gumi nemashanu kuti uwedzere kanopi uye kukwikwidza nesora.Ehe, kurima dzimwe nguva isarudzo, asi funga zvipingamupinyi - kuwedzera kwemutengo wemafuta, kuyerera kwevhu, kuputsa munda wenguva refu usingarima - usati wangopfuura nekudzura pasi.
Scouting, Lingenfelter anoti, kuchave kwakakosha, sezvichaita zvinokatyamadza tarisiro pamusoro pekuve neminda yakanyanya pristine.
“Gore rinouya kana maviri, tingave tichiona minda ine sora yakawanda,” anodaro."Gadzirira kubvuma 70% kurwisa sora pane 90% kudzora mamwe masora."
Asi pane zvinokanganisa kufunga uku, zvakare.Sora rakawanda zvinoreva goho rakaderera, Lingenfelter anodaro, uye dambudziko resora richanetsa kudzora.
"Paunenge uchibata nePalmer uye waterhemp, 75% kudzora sora hakuna kukwana," anodaro."Lambsquarter kana red root pigweed, 75% kutonga kunogona kunge kwakakwana.Mhuka dzemasora dzichataura kuti dzinogona sei kusununguka nekudzora sora. "
Gary Snyder wekuNutrien, anoshanda nevarimi vangangosvika zana nemakumi mashanu kumaodzanyemba kwakadziva kumabvazuva kwePennsylvania, anoti chero mushonga wesora uchange uripo — glyphosate kana glufosinate — uchange uchipihwa migove nekudyiswa chipunu.
Anoti varimi vanofanira kuwedzera mishonga yavo yesora muchirimo chinotevera kuti zvinhu zvikurumidzwe, saka sora harisi dambudziko guru pakudyara.
Kana usati wasarudza chibage chakasanganiswa kusvika pari zvino, Snyder anokurudzira kuwana mhodzi ine mageneti emhando yepamusoro anowanikwa pakubvisa sora.
“Chinhu chikuru imbeu chaiyo,” anodaro.“Pfapfaidza nekukurumidza.Ramba wakatarira chirimwa kutiza sora.Zvigadzirwa kubva kuma'90s zvichiri kutenderera uye zvinogona kuita basa.Funga zvose. "
Bowling anoti arikuchengeta sarudzo dzake dzese dzakavhurika.Kana mitengo yemishonga ikaramba ichikwira, kusanganisira yemishonga yesora, uye mitengo yezvirimwa ikasakwira kuti zvienderane, anoti achachinja maeka akawanda nesoya bhinzi nekuti dzinodhura pakurima, kana kuti anozoshandura maeka akawanda kuita huswa.
Lingenfelter inotarisira kuti varimi havamirire kusvika kupera kwechando kana chirimo kuti vatange kuterera nyaya.
“Ndinovimba kuti vanhu vari kuzvitora zvakakomba,” anodaro.'Ini ndinotya kuti kuchave nevanhu vazhinji vachabatwa vasina kungwarira vachingofungidzira kuti vanogona, huyai Kurume, enda kumutengesi wavo moisa odha uye nekutakura rori remishonga yesora, kana mishonga yekuuraya zvipembenene, kumba zuva iroro.Ndinofunga kuti kuchava nekumuka kusina kunaka kusvika pamwero wakati.
