Cwilisa amasimi akho eembotyi ezomileyo? Qiniseka ukuba usebenzisa izibulali-zinambuzane ezisele.

Malunga nama-67 ekhulwini abalimi beembotyi ezomileyo ezityiwayo eNorth Dakota naseMinnesota balima amasimi abo eembotyi zesoya ngaxa lithile, ngokutsho kophando lwabalimi, utsho uJoe Eakley weNorth Dakota State University's Weed Control Center.
Ziqengqeleke phakathi ngaphambi kokuba iinkozo zivele. Ethetha kwiMini yeembotyi ka-2024, uthe ezinye iimbotyi ziyaqengqeleka ngaphambi kokuba zityalwe, kwaye malunga ne-5% ziyaqengqeleka emva kokuba iimbotyi zimile.
“Yonke iminyaka ndifumana umbuzo. Uyazi, ngokusisiseko, ndingayiqengqa nini njengoko kunxulumene nokusetyenziswa kwam kwe-residual herbicide? Ngaba ikho inzuzo yokutshiza i-herbicide kuqala uze uyiqengqe, okanye ukutshiza i-herbicide kuqala?” uze uyiqengqe?” – utshilo.
Ukujikeleza kutyhala amatye ezantsi nakude kwisixhobo sokuvuna, kodwa isenzo sikwabangela ukuxinana komhlaba, “njengengozi yendlela yamatayara,” utshilo uYackley.
“Apho kukho ukuxinana okuthile, sidla ngokufumana uxinzelelo olukhulu lokhula,” uyacacisa. “Ngoko ke ukuqengqeleka kwamavili kufana nolu. Ngoko ke besifuna ngokwenene ukujonga isiphumo sokuqengqeleka kuxinzelelo lokhula emasimini, size sijonge kwakhona ulandelelwano lokuqengqeleka ngokuchasene nokusebenzisa i-residual herbicide.”
U-Eakley kunye neqela lakhe benze uvavanyo lokuqala "lokuzonwabisa nje" kwiimbotyi zesoya, kodwa uthi imfundiso yebali iyafana naleyo bayifumene kamva kwiimvavanyo ngeembotyi ezityiwayo.
“Apho singenazo iirola okanye iiherbicides, sinengca ezimalunga ne-100 kunye nemithi engama-50 evuthulukayo kwiyadi yesikwere,” utshilo malunga novavanyo lokuqala ngo-2022. “Apho sivuthuluka khona, sinengcinezelo yengca ephindwe kabini kwaye siphindwe kathathu uxinzelelo lwe-broadleaf.” “
Icebiso lika-Eakley lalilula: “Ngokwenene, ukuba uza kulungela kwaye wenze into, nantoni na esebenza kakuhle ngokwezicwangciso, asiboni mahluko kwixesha.”
Uqhubeka echaza ukuba ukuqengqa nokusebenzisa i-residue herbicide ngaxeshanye kuthetha ukuba kuvela ukhula oluninzi kodwa lulawulwa.
“Oko kuthetha ukuba singabulala ukhula oluninzi ngale ndlela,” utshilo. “Ngoko ke enye yezinto endiziqwalaselayo kukuba, ukuba siza kuqalisa, siqinisekise ukuba sineebhidi eziseleyo, ezinokuba luncedo kuthi ekuhambeni kwexesha.”
“Asiboni mpembelelo ingako emva kokuvela kokhula kwisityalo ngokwaso,” utshilo. “Ngoko ke kubonakala kulungile nakuthi.”
