Kudliwanondlebe noMlawuli weMveliso yobuGcisa yeSyngenta ye-Herbicide yase-US, uDane Bowers, kudliwano-ndlebe malunga nendlela abathengisi kunye nabalimi abafanele baphendule ngayo kwixesha le-2021, ukhankanye umyalezo wakhe wokuthatha ekhaya kule minyaka imbalwa idlulileyo: Ukulawula ukuchasana akuyena umntu kodwa ingxaki yobugcisa.Imiba yokuziphatha.
“Ngokwembono yobugcisa, ndicinga ukuba sinombono omhle kakhulu.Zikho iingxaki—ungandivi kakubi,” wavuma, “kodwa sonke sizizidalwa.Ukuba iyasisebenzela, siqhele ukwenza into efanayo. ”
Sifuna ukucinga ukuba u-2021 uza kuzisa ukuchacha kuzo zonke iinkalo, kodwa kude kube ngoko, eli lixesha elihle lokuqonda undoqo wolawulo lokhula.Kuphela wabona ukhula oluthile lubaleka, kodwa aluninzi kakhulu?Bowles wacebisa oku: “Le ifanele ibe yicanary kumgodi wamalahle.”“Nanini na xa ubona iziganeko zokuqhwesha ezimbalwa endle, kufuneka ucinge malunga nokuba kudala ndisebenzisa le nkqubo, nokuba andizifakanga ngokwaneleyo ezinye iindawo zokusebenza kwinkqubo yam yokutshabalalisa ukhula.Ngawaphi amanye amanyathelo ekufuneka ndiwathathe ukuthintela le meko?Ngokuqhelekileyo, kunyaka wokuqala wokuchasa, awucingi ukuba unengxaki, kwaye ke kunyaka wokuqala Kwaba mbi kakhulu kwiminyaka emibini.Kunyaka wesithathu, yaba yintlekele.Ngokwenene yayilinyathelo elingaphambili.”
Kuluhlu lweengcebiso ze-Bowers zexesha elizayo lonyaka, kwaye zaqinisekiswa ngoososayensi bezolimo abangabalekiyo, zezi: 1) ukuqonda imingeni ekhethekileyo yayo nayiphi na ifama enikiweyo, kunye nemichiza yokutshabalalisa ukhula kubaqhubi, kunye 2) nokuqonda imfuneko yokuqalisa ukucoca nokuyigcina icocekile.Oku kuthetha ukuba kugalelwe imichiza yokutshabalalisa ukhula eyomeleleyo phambi kokuba kuvele, kwaye ke emva koko kugalelwe imichiza yokutshabalalisa ukhula enqwabelanayo kwiintsuku ezili-14 ukuya kwezingama-21 kamva.Imichiza yokutshabalalisa ukhula kufuneka idibanise iisayithi ezininzi ezisebenzayo ukunciphisa umngcipheko wokumelana nokhula.
“Eyona nxalenye ibalulekileyo idla ngokuba yeyona inzima.Enyanisweni, siye sabambelela kwisicwangciso kuba ixabiso kunye neemeko zokusingqongileyo ziya kusithintela ekwenzeni isigqibo esifanelekileyo, "utshilo uDrake Copeland, uMphathi weeNkonzo zobuGcisa be-FMC e-Ohio, eMichigan.
UWolfe uthe: "Ndicinga ukuba xa ucinga ngemichiza yokutshabalalisa ukhula, inkqubo elungileyo yokushiyeka eneendlela ezininzi zokwenza ifanele ibe lolona khetho lwakho lokuqala."“Xa uqhuba ngasentshona ngo-Agasti nasekuqaleni kukaSeptemba, Indawo oyibonayo ilula kakhulu.Intsalela yaba bantu yehlile, kwaye iintsalela ezingakumbi zongezwa ngeli xesha lonyaka.Amasimi abo abukeka elungile kakhulu kwaye akukho phantse kuqokelelwa kwamanzi.Abantu abatsiba intsalela, iMinnesota, Iowa kunye neDakota kufuneka ukuba babone uninzi lwe-cannabis ngasekupheleni kwehlobo kunye nokuwa kwangoko.
U-Bowers ugxininise ukubaluleka kokusebenzisa imichiza yokutshabalalisa ukhula ngaphambi kokuntshula kwiimveliso ze-dicamba, ingakumbi ngokuqwalasela ukuba uGqr. Larry Steckel weYunivesithi yaseTennessee (L) uchonge kuqala i-Palmer ngokuchasene ne-dicamba.
USteckel ubhale kwibhlog yakhe ye-UT ukuba ujonge phambili ku-2021, ngoku kuyafuneka ukuba ufake isicelo kwangaphambili okushiyekileyo okusebenzayo kuPalmer.Ukongeza, inkululeko kufuneka isetyenziswe ngokukhawuleza emva kokusetyenziswa kwe-dicamba ukuphelisa ukubaleka.
USteckel ubonise ukuba le yimowudi yesihlanu yokutshabalalisa ukhula uPalmer avelise eTennessee ukusukela ngo-1994. ukusebenzisa.”
Kwipotfoliyo yemveliso yeSyngenta, itekhnoloji yeTavium Plus VaporGrip idicamba premix ine-S-alachlor, ebonelela ngeeveki ezintathu zomsebenzi oshiyekileyo kune-dicamba yodwa.Inkampani ithi xa imichiza yokutshabalalisa ukhula emva kokuhluma isetyenziswa kwimichiza yokutshabalalisa ukhula yangaphambi kokuvela (efana neBoundary 6.5 EC, BroadAxe XC okanye imichiza yokutshabalalisa ukhula kwiPrefix), “inika elona thuba lihle lokupasa umchiza wokutshabalalisa ukhula emva kokuvela kwiimbotyi zesoya ngexesha elinye”.
“Le yimveliso enamandla kakhulu, akukhathaliseki nokuba uneziphi na iimpawu, ungalutshabalalisa ukhula phambi kweembotyi zesoya, kwaye ibonelela ngomlinganiselo othile wokuguquguquka kuba asiwafaki onke amaqanda kwintsalela yokupakishwa.Ungabuya ngokukhawuleza ukusebenzisa iqela le-15 lemichiza yokutshabalalisa ukhula, kwaye iqulethe isixa esipheleleyo sexylazine.UGqr Daniel Beran, uMlawuli weeNkonzo zobuGcisa base-Nufarm wase-US, uxelele iCropLife®.
“Singakwazi ukuphelisa ukungaqiniseki okuthile kwaye simisele inkqubo yokudinwa kunye nentsalela ngokuguquguquka okuhle.Ukuba iimpawu ziyatshintsha okanye izixhobo zesicelo kwisityalo zithintelwe okanye utshintsho oluthile lwexesha lesicelo, ngoko kufuneka kubekho okulungileyo Inkqubo eseleyo yokutshabalalisa ukhula iya kunciphisa kakhulu ubunzima bolu tshintsho. "Wabonisa ukuba ngoku kwi-Nufarm, kunomdla ukuba ube ngumntu wesithathu kwintsimi ye-dicamba kunye ne-2,4-D iteknoloji.Umzuzu-wenza abameli beenkampani bancede abathengisi baphinde bafunde iziseko.
Enye imveliso entsha yokutshiswa kwangaphambili kwesityalo yiReviton yasungulwa nguHelm Agro eUnited States.Yi-PPO inhibitor yokutshabalalisa ukhula kunye nesithako esitsha esisebenzayo iTergeo yombona wasendle, umqhaphu, iimbotyi zesoya kunye nengqolowa.Ngaphezulu kwe-700 yolingo lophuhliso lwemveliso yaseMntla Melika kunye nezifundo zolawulo, i-Reviton ibonakalise ukuba "ngaphezu kwama-50 amagqabi abanzi kunye nokhula lwengca (kubandakanya i-ALS, i-triazine kunye neentlobo ezixhathisa i-glyphosate) zithembisa kakhulu kulawulo lokudinwa kwenqanaba lokuSebenza."
Ngokuhla kwamaxabiso ezinto zorhwebo, iCopeland ibone izivuno ezilungileyo (ukwanda kwezityalo) kunye neemeko ezimbi (ukuncitshiswa kokusetyenziswa kwemichiza yokutshabalalisa ukhula).
Uthe: "Iintsalela ze-herbicide kwisicelo samva ngundoqo ekugcineni ukutshatyalaliswa kokhula okushiyekileyo okufunekayo ukuze isityalo sivalwe kwi-canopy," wongezelela, "Ukongezelela, i-herbicides eseleyo ayiyi kuhoywa kuyo nayiphi na isicelo.Ukwandisa imbuyekezo yembewu kwibhanki yembewu yomhlaba ekugqibeleni kuya kuvumela ukuba kusetyenziswe imali eyongezelelekileyo kwiipaseji ezongezelelweyo entsimini ukucoca ubumdaka. "
UCopeland ubize iDyunivesithi yasePurdue ukuba iqhube uphando, olufumanise ukuba ukuhlangana okushiyekileyo yeyona ndlela yokunciphisa ulawulo lwebhanki yembewu yonyaka wokuqala.Unyango ngaphandle kokusasazwa kwemichiza yokutshabalalisa ukhula eshiyekileyo eneendawo ezininzi zesenzo kukhokelele ekunyukeni okubukhali koxinano lwehempe yamanzi anokutyiwa kwibhanki yembewu.Ngokuchaseneyo, inkqubo yentsalela yexesha elide yasemva kokuvela isetyenziselwe ukugqithana kweentsalela zentsalela ukunciphisa ubushushu bamanzi Ukuya kuma-34% (jonga umfanekiso ongezantsi).
Uthe: "Idatha efana nale inokunceda abathengisi bethu kunye neengcali zezolimo ukuba zithethe nabalimi.""Banokuthi, 'Ndiyazi ukuba amaxesha anzima, kodwa ukuba sifuna ukufezekisa ikamva elizinzileyo kwifama yakho, akukho mfuneko yokuba sinqumle into, nokuba kusefektri okanye phezulu, sinokuyinciphisa intsalela. i-herbicide.'”
Njengoko uGqr. Bob Hartzler wachazayo kwiBlog ye-Iowa State University Integrated Pest Management Blog: “Ngenxa yokwanda ngokukhawuleza kokhula oluxhathisa ukhula, iindlela zangoku zase-Iowa zokulawula ukhula zisemngciphekweni Ukuze kugcinwe ukusebenza kwemichiza yokutshabalalisa ukhula, kufuneka kwenzeke izinto ezimbini: 1) ukwamkela ulawulo oludibeneyo lokhula;2) ukutshintsha injongo yokulawula ukhula ekukhuseleni izivuno zezityalo ukuya ekucutheni ubungakanani beebhanki zembewu yokhula.Into yokuqala efunekayo kukutshintsha iNdlela yokuZiphatha, eyesibini ifuna ukutshintsha isimo sengqondo.”
Ukongeza kwiindleko zokutsiba iintsalela zangaphambi kokuvela, i-Syngenta's Bowers ikwalumkise ngamayeza “enkohliso” awenziwe afana nalawo aveliswe ngumenzi ukonga imali.
I-Bowers yazisa uvavanyo lozinzo olusemgangathweni olwenziwa nguSyngenta kwiimveliso ngokubanzi.Ukuba izithako ezisebenzayo azenziwanga ngokuchanekileyo, i-AI inokuhlaselana kwaye ithobe imichiza ekhoyo.Xa umlimi esebenzisa imveliso apho kuphela i-80% ye-AI isebenza, akanakuhlangabezana neengxaki zokuxuba kuphela, kodwa unokuyisebenzisa kumlinganiselo ophantsi kuneleyibhile kwaye umphumo we-herbicidal ungaphantsi kunokuba ulindeleke.
U-Bowers uthe umzekelo othile kukuba abantu bavame ukusebenzisa ifomula ngokubanzi, eyindibaniselwano ye-AI S-metolachlor kwi-Dual II Magnum kunye ne-AI mesotrione e-Callisto, apho i-Syngenta inokubonelela ngeendidi ze-corn premixes, ezifana ne-Acuron.Kwi-premix ye-mesotrione kunye ne-S-metolachlor, "Ukuba i-S-metolachlor ayilungiswanga kakuhle, iya kuthoba i-mesotrione ekhoyo."
Bowers wongeze wathi: “Sisigqibo esingcono ukuchitha iidola ezimbalwa ngaphambili kwaye uhlengahlengise isicwangciso sokutshabalalisa ukhula ukunika iziphumo ezingcono zokulukhula, ukuze iibhasi ngehektare nganye zibengcono.Xa amaxabiso ezinto zorhwebo ephantsi, velisa ngakumbi Iibhasi ezininzi zizitshixo zakho.Asizukuyigcina indlela yempumelelo, ngoko ke kufuneka sigcine ibhalansi kwinkcitho engafanelekanga, kodwa kufuneka siqinisekise ukuba uyalifumana ixabiso lotyalo-mali lwakho kunye nembuyekezo ngeedola.
