REDFIELD, Iowa (DTN) – Isazi zishobora kuba ikibazo ku matungo y’inka mu gihe cy’impeshyi n’izuba. Gukoresha uburyo bwiza bwo kugenzura amatungo mu gihe gikwiye bishobora gufasha kugera ku nyungu ku ishoramari.
“Ingamba nziza zo kurwanya udukoko zishobora gufasha mu kurwanya udukoko neza,” ibi byavuzwe na Gerald Stokka, umuganga w’amatungo akaba n’inzobere mu gucunga amatungo muri Kaminuza ya North Dakota State. Ibi bivuze ko kurwanya udukoko bikwiye mu gihe gikwiye kandi mu gihe gikwiye.
Stoica yagize ati: “Mu gihe cyo korora inyana z’inka, kurwanya udukoko tw’inyenzi n’udukoko mbere yo kuragira ntabwo bizagira ingaruka nziza kandi bigatera gutakaza ubushobozi bwo kurwanya udukoko.” Igihe n’ubwoko bwo kurwanya udukoko biterwa n’ubwoko bw’udukoko.”
Isazi zo mu bwoko bwa Hornflies n'izo mu mazi ubusanzwe ntizigaragara kugeza mu ntangiriro z'impeshyi kandi ntizigera ku rwego rw'ubukungu rwo kuzigenzura kugeza hagati mu mpeshyi. Isazi zo mu bwoko bwa Hornflies ni imvi kandi zisa n'izikomoka ku matungo mato. Iyo zitagenzuwe, zishobora kwibasira amatungo inshuro zigera ku 120.000 ku munsi. Mu masaha y'akazi kenshi, isazi zigera ku 4.000 zishobora kuba ku ruhu rumwe rw'inka.
Elizabeth Belew, inzobere mu mirire y’inka muri Purina Animal Nutrition, yavuze ko isazi zo mu bwoko bwa slingshot gusa zishobora guhombya inganda z’amatungo zo muri Amerika miliyari imwe y’amadolari ku mwaka. Yagize ati: “Kurwanya isazi z’inka mu ntangiriro z’igihembwe bishobora kugira ingaruka zikomeye mu kugenzura ubwinshi bw’inka mu gihe cyose cy’umwaka.”
Stokka yongeyeho ati: “Kurumana igihe cyose bishobora gutera ububabare n’imihangayiko mu nka kandi bishobora kugabanya ibiro by’inka kugeza ku biro 20.”
Isazi zo mu maso zisa n'isazi nini zo mu nzu yijimye. Ni isazi zidaruma zirya amacandwe y'inyamaswa, imyuka y'ibimera n'amazi y'umwanda. Izi sazi zishobora kwanduza amaso y'inka zigatera indwara ya conjunctivitis. Izi sazi akenshi ziba nyinshi mu mpera z'impeshyi.
Isazi zisanzwe zisa n'iz'inzu, ariko zifite ibimenyetso by'uruziga bizitandukanya n'iz'ihembe. Izi sazi zirya amaraso, akenshi ziruma inda n'amaguru. Biragoye kuzigenzura iyo zisutse cyangwa zitewe inshinge.
Hari ubwoko butandukanye bw’uburyo bwo kugenzura indege, kandi bumwe bushobora gukora neza kurusha ubundi mu bihe bimwe na bimwe. Nk’uko Belew abivuga, uburyo bwiza kandi bworoshye bwo kugenzura isazi z’ihembe mu gihe cyose cy’isazi ni ugutanga imyunyu ngugu irimo imiti igenzura gukura kw’udukoko (IGRs), ikwiriye ubwoko bwose bw’inka.
Asobanura agira ati: “Iyo inka zirimo IGR ziriye iyi myunyu ngugu, inyura mu nyamaswa ikajya mu mwanda mushya, aho isazi y’ingore ikuze itera amagi. IGR ibuza ibibwana gukura bikaba isazi zikuze ziruma.” Ni byiza kugaburira amatungo iminsi 30 mbere y’ubukonje bwa nyuma mu mpeshyi na nyuma y’iminsi 30 nyuma y’ubukonje bwa mbere mu gihe cy’impeshyi kugira ngo amatungo agere ku rwego rw’ingenzi.
Colin Tobin, umuhanga mu by’inyamaswa mu kigo cy’ubushakashatsi cya NDSU cya Carrington, yavuze ko ari ingirakamaro gusuzuma ubwatsi kugira ngo hamenyekane isazi zihari n’umubare wazo. Ibirango byo mu matwi, birimo imiti yica udukoko irekurwa buhoro buhoro mu bwoya bw’inyamaswa uko igenda, ni amahitamo meza, ariko ntibikwiye gukoreshwa kugeza igihe isazi zizaba nyinshi hagati muri Kamena kugeza Nyakanga, nk’uko yabitangaje.
Agira inama yo gusoma ibirango, kuko ibirango bitandukanye bishobora gutandukana bitewe n'ingano yo gukoresha, imyaka y'inka ishobora kuvugwa, n'urwego rw'imiti rw'ikintu gikora. Ibirango bigomba gukurwaho igihe bitagifite agaciro.
Ubundi buryo bwo kugenzura ni ugushyiramo imiti mu nkono n'imiti ikoreshwa mu gutera inyamaswa. Akenshi ishyirwa ku gice cyo hejuru cy'inyamaswa. Iyi miti iracengera ikazenguruka umubiri wose w'inyamaswa. Iyi miti ishobora kurwanya isazi mu gihe cy'iminsi 30 mbere yuko yongera gukoreshwa.
“Kugira ngo isazi zigenzurwe neza, imiti ikoreshwa mu gutera isazi igomba gushyirwamo buri byumweru bibiri cyangwa bitatu mu gihe cyose cyo kuguruka,” Tobin yagize ati.
Mu bihe byo gukoresha ku ngufu, uburyo bwiza bwo kurwanya isazi ni ugukusanya ivumbi, udupira two guhanagura inyuma n'amacupa y'amavuta. Bigomba gushyirwa ahantu amatungo ashobora kubona kenshi, nko mu masoko y'amazi cyangwa aho kugaburira. Ifu cyangwa amazi akoreshwa nk'umuti wica udukoko. Bellew amenyesha ko ibi bisaba igenzura rihoraho ry'ibikoresho byo kubikamo imiti yica udukoko. Inka zimaze kubona ko bizifasha, zizatangira gukoresha ibyo bikoresho kenshi, nk'uko yabitangaje.
