Hauv kev sib ntaus sib tua tas mus li kom cov taum teb huv si, ob peb cov nroj tsuag tau ua pov thawj nyuaj rau cov neeg ua liaj ua teb los tswj xws li waterhemp.
"Xyoo tas los, xyoo 2025 peb tau tawm tsam ntau nrog waterhemp, thiab qhov ntawd yog cov nroj tsuag uas tseem yuav nthuav tawm cov teeb meem rau peb ntxiv," sau tseg Mike Hannewald, tus kws tshaj lij agronomist nrog Beck's Hybrids.
Kev sib tw raws caij nyoog los ntawm waterhemp (ntau tshaj 20 nroj tsuag ib square feet) tau pom tias yuav txo tau cov taum pauv los ntawm 44%. Waterhemp tshwm sim lig li V5 soybean txo yields txog 10%, raws li Take Action.
Hannewald cov lus rau cov neeg ua liaj ua teb rau xyoo 2026 yog qhov no: Kev tswj cov dej hemp tsis yog hais txog ib qho khoom lossis dhau. Nws yog hais txog kev tsim ib qho kev xav, txheej txheej tshuaj tua kab mob uas pib ua ntej cog qoob loo.
Nov yog cov ntsiab lus ntawm plaub qhov kev coj ua tseem ceeb uas nws pom zoo:
1. Pib lub caij nrog tej teb huv si.
Thawj lub hauv paus ntsiab lus yog kev dag ntxias yooj yim: pib huv si.
Hannewald qhia txog kev siv cov tshuaj tua kab mob tua kab mob los yog teeb tsa tillage kom zoo yog tias koj nyob rau hauv cov pa tillage kom tshem tawm cov nroj tsuag uas twb muaj lawm ua ntej cog.
2. Siv daim ntawv thov "peb nyob rau hauv pre" tshuaj tua kab mob
Beck's Practical Farm Research (PFR) cov ntaub ntawv qhia tau hais tias thaum peb hom kev nqis tes ua yog siv nyob rau hauv ib daim ntawv thov ua ntej - tawm los tswj dej hemp, 97% kev tswj tau ua tiav thiab khaws cia 45 hnub tom qab kho.
Hannewald hais tias "Qhov seem seem tuaj yeem ua tau tom qab peb ua peb cov tillage lossis ua ke nrog peb qhov kev kub hnyiab," Hannewald hais.
Vim tias muaj ntau cov khoom xyaw nquag muaj - thiab ntau lub npe khoom lag luam - nws yog ib qho yooj yim kom tsis tau txais peb qhov sib txawv chemistry hauv lub tank. Txhawm rau pab txo qhov tsis meej pem, Hannewald pom zoo kom hloov mus rau hauv cov lej ntawm chemistry.
Nws pom zoo kom cov neeg cog qoob loo siv qee qhov sib xyaw ntawm peb cov tshuaj tua kab mob los ntawm plaub pawg no:
Pawg 2: Amino acid synthesis inhibitors, xws li cloransulam.
Pawg 5: Photosynthesis inhibitors, xws li metribuzin.
Pawg 14: Cell membrane disruptors, xws li sulfentrazone
Pawg 15: Seedling cag kev loj hlob inhibitors, xws li metolachlor, acetochlor thiab pyroxasulfone
"Tam sim no, yog tias koj cog XtendFlex soybeans thiab koj tab tom siv ib qho kev pom zoo ntawm dicamba raws li koj qhov hlawv, dicamba puas muaj nqi seem, yog li suav tias yog ib qho ntawm peb," Hannewald hais. "Tab sis yog tias koj siv 2,4-D ntawm Enlist soybeans, 2,4-D tsis muaj nqi seem, yog li ntawd tsis suav. Koj yuav tsum tau ntxiv peb hom kev ua haujlwm ntxiv rau qhov ntawd."
3. Ua ib qho kev tshaj tawm - tshuaj tua kab mob ua ntej paj
Yog tias tsim kom muaj lub tswv yim ua ntej muaj zog yog ib feem ntawm chemistry, cov kauj ruam tom ntej - lub sijhawm xa ntawv hla dhau - yog hais txog kev xav. Rau ntau tus neeg cog qoob loo taum, tos kom txau kom txog thaum cov nroj tsuag pom tseeb yog ib qho kev coj ua. Hannewald ntseeg tias nws yog lub sijhawm los hloov qhov kev xav ntawd.
Nws hais tias "Qhov no yog qhov kev xav loj tshaj plaws rau peb nyob ua ntej ntawm waterhemp, thiab qhov ntawd yog txau koj cov taum pauv ua ntej paj," nws hais.
Hauv cov ntsiab lus siv tau, qhov no txhais tau tias txav cov ncej dhau los ua ntej ntau tus neeg ua liaj ua teb siv rau -feem ntau thaum daim teb zoo li huv si (xws li nyob ib puag ncig V3 es tsis yog R1).
"Feem ntau, tej zaum koj yuav tau tsav tsheb los ntawm kev xav, 'Kuv tsis tas yuav tawm ntawm no rau lub sijhawm no vim tias tsis muaj nroj tsuag ntau, yog tias tag nrho," nws hais.
Tab sis tsom rau cov nroj tsuag me me thaum ntxov, ua ntej taum canopy, tso cai rau koj kom tau txais kev pab zoo thiab tswj. Qhov no yog qhov tseem ceeb tshwj xeeb yog tias koj yuav tshuaj glufosinate (Kev ywj pheej), qhia Isaac Ferrie, Crop-Tech Consulting field agronomist.
Raws li cov Daim ntawv lo Liberty tuaj yeem txau rau ntawm LibertyLink soybeans los ntawm qhov tshwm sim mus txog R1 kev loj hlob theem (thawj paj).
"Qhov ntawd txhais tau hais tias ib zaug 50% ntawm cov nroj tsuag tawm muaj ib lub paj rau lawv, peb tsis tuaj yeem txau Liberty," Ferrie hais.
Lwm qhov kev txiav txim siab yog qhov cuam tshuam ntawm kev siv tshuaj tua kab tom qab ntawm cov peev txheej tawm los.
Ib txoj kev tshawb fawb PFR uas piv cov ntawv siv tshuaj tua kab hauv cov taum pauv ntawm V3 rau cov uas tau ua ntawm R1 pom tias daim ntawv thov tom kawg ua rau cov qoob loo poob qis.
"Peb pom poob ntawm 1.2 bushels mus rau 2.5 bushels ib evkawj tsuas yog los ntawm R1 daim ntawv thov hais tias cog taum mog," Hannewald piav qhia. "Txawm hais tias peb cov taum ua siab ntev rau cov tshuaj tua kab mob no, nws tseem siv zog rau cov nroj tsuag soybean los ua cov tshuaj tua kab mob, metabolize nws, zom nws thiab tshem tawm, thiab lub zog ua rau muaj kev ntxhov siab rau cov nroj tsuag."
4. Ntxiv ib qho nyob rau hauv -lub caij nyoog seem nrog daim ntawv hla tebchaws
Kauj Ruam 4 yog ntxiv ib qho nyob rau hauv - lub caij seem rau daim ntawv hla tebchaws. Qhov no yog dab tsi ua rau thaum ntxov post pass ua haujlwm.
"Lub sijhawm no, peb tseem muaj qee qhov av pom, thiab thaum peb ntxiv qhov ntawd hauv - lub caij seem, nws zoo li koj tab tom tso ib daim pam hla cov av ntawd kom tsis txhob lig - cov dej hemp los ntawm kev loj hlob," Hannewald hais.
Nws hais ntxiv tias nws nyiam siv Pawg 15 tshuaj tua kab mob raws li qhov seem tam sim no, vim tias lawv siv tau rau cov me me - noob broadleaf nroj tsuag.
Hannewald hais tias Beck's PFR qhia tias cov neeg ua liaj ua teb tau txais 6% kev tswj hwm ntxiv - mus los ntawm 88% mus rau 94% kev tswj hwm ntawm waterhemp thaum sau - los ntawm kev ntxiv rau hauv - caij nyoog seem.
"Txawm hais tias 6% yuav tsis zoo li tag nrho, uas ua haujlwm rau 17.1 lab tsawg dua cov noob qoob loo hauv ib daim acre mus rau hauv peb lub txhab nyiaj rau xyoo tom ntej thiab xyoo tom ntej," nws hais.
Nyob rau hauv cov ntsiab lus, Hannewald boils nws cov lus pom zoo rau 2026 mus rau plaub- kauj ruam lub hauv paus: pib huv si, txheej peb hom kev txiav txim rau hauv pre pass, txav daim ntawv thov ua ntej- ua ntej flowering-thiab ntxiv ib qho nyob rau hauv - lub caij seem mus nqa teb los ntawm canopy thiab mus sau qoob.
