Natiijooyinka qaar ka mid ah tijaabooyinka aqalka dhirta lagu koriyo ee jiilaalka iyo gu'ga iyo natiijooyinka daraasadaha gudaha ee xilli-koritaanka ayaa muujiyay in Palmer Palm khudradda dicamba (DR) ay u adkaysato.Dadkan DR-ka ah waxa laga aasaasay gobollada Crockett, Gibson, Madison, Shelby iyo Warren iyo suurtogalnimada dhawr degmo oo kale.
Heerka iska caabinta dicamba waa mid hooseeya, qiyaastii 2.5 jeer.Goob kasta oo la bixiyo, heerka cudurku wuxuu ka bilaabmaa jeeb yar, halkaas oo geedka waalidka dheddigga ah lagu beero 2019, aagguna wuxuu daboolayaa dhowr hektar.Tan waxaa la barbar dhigi karaa markii ugu horeysay ee la diiwaan geliyo glyphosate-u adkeysiga Palmer mar khudradda laga helay Tennessee 2006. Waqtigaas, badi beeralayda ayaa weli si fiican u xakameynaya glyphosate Palmer mar khudradda, halka beero kale uu qofku ogaaday baxsashada beertiisa.
Markii ugu horreysay ee dalagyada Xtend ay ka soo muuqdeen goobta, ma ahayn wax aan caadi ahayn in khudaarta Palmer mar ay ka baxsadaan dicamba, taas oo meel walba ka leexday.Baxsashadani waxay kori doontaa wax yar ama ma koraan 2 ilaa 3 toddobaad gudahood.Dabadeed, inta badan dalagyada waxaa qarsoomi doona dalagyada oo dib looma arki doono.Si kastaba ha ahaatee, maanta meelo gaar ah, DR Palmer mar suxuunta ayaa bilaabaya inay mar kale u koraan tiro aan horay loo arag ilaa 10 maalmood gudahood.
Qaar ka mid ah sifooyinka gaarka ah ee daraasaddan ayaa ah baaritaanka DR haramaha ee aqalka dhirta lagu koriyo ee Jaamacadda Tennessee iyo Jaamacadda Arkansas.Daraasadani waxay muujineysaa in dulqaadka Palmer ee khudradda dicamba uga baxsaday beero badan oo ku yaal Tennessee sanadka 2019 ay tahay midda Palmer khudradda laga soo ururiyay Arkansas iyo Tennessee toban sano ka hor.In ka badan 2 jeerTijaabooyin aqalka dhirta lagu koriyo oo xigay oo lagu qabtay Jaamacadda Texas Tech waxay muujiyeen in dadka laga soo aruuriyay Degmada Shelby County, Tennessee ay 2.4 jeer uga dulqaad badnaayeen dicamba marka loo eego Parma a ee Lubbock, Texas (Jaantuska 1).
Tijaabooyin soo noqnoqda ayaa lagu sameeyay qaar ka mid ah dadka lagu tuhunsan yahay Palmer ee Tennessee.Natiijooyinka tijaabooyinkan goobuhu waxay ka tarjumayaan shaashadaha aqalka dhirta lagu koriyo, oo muujinaya in 1x heerka codsiga dicamba ee calaamadeysan (0.5 lb/A) uu bixin karo 40-60% Palmer mar kantaroolka khudradda.Tijaabooyinkan, codsiga xiga ee dicamba ayaa wax yar uun hagaajiyay xakamaynta (Jaantus 2, 3).
Ugu dambeyntii, beeraley badan ayaa soo sheegaya inay u baahan yihiin inay ku buufiyaan isla Palmer mar khudradda 3 ilaa 4 jeer si loo xakameeyo.Nasiib darro, warbixinnadani waxay muujinayaan in aqalka dhirta lagu koriyo iyo daraasaadka goobtu ay ka tarjumayaan waxa qaar ka mid ah la taliyayaasha, tafaariiqlayaasha iyo beeralayda Tennessee ay ku arkaan beeraha.
Haddaba, ma la gaadhay waqtigii argagaxa?mayaSi kastaba ha ahaatee, waa waqtigii dib loo qiimeyn lahaa maaraynta haramaha.Hadda, maaraynta dhirbaaxada ayaa aad uga muhimsan waligeed.Tani waa sababta aan xoogga u saarno isticmaalka herbicides-ka daboolan ee suufka, sida paraquat, glufosinate, Valor, diuron, metazox iyo MSMA.
Marka aan sugno 2021, hadda waa lagama maarmaan in si wax ku ool ah loo isticmaalo hadhaaga buufinta PRE ee Palmer.Intaa waxaa dheer, xorriyadda waa in isla markiiba la isticmaalo ka dib isticmaalka dicamba si loo baabi'iyo baxsashada.Ugu dambeyntii, daraasado horudhac ah ayaa muujiyay in DR Palmer mar uu sidoo kale aad ugu adkeysanayo 2,4-D.
Sidaa darteed, tani waxay ka dhigaysaa Liberty ka-hortagga doogga ugu muhiimsan ee nidaamka maaraynta haramaha ee Xtend iyo Enlist dalagga.
