.Nubwo ubu uburyo bwo kurwanya imiti yica udukoko muri Amerika bwibanda ku burozi bukabije bw’imiti yica udukoko kandi bushobora gutekereza ku ngaruka zimwe na zimwe zidakira, ibintu bigoye ku isi byasobanuwe muri ubu bushakashatsi ntibyigeze bisubirwamo.Ibyuho mu isuzuma ryacu ntabwo bizazana ingaruka mbi gusa kubinyabuzima, ahubwo bizana no kubidukikije byose.
Abashakashatsi bakoze ubushakashatsi ku buryo parasite fungal bita chytrids igenzura imikurire ya phytoplankton.Nubwo ubwoko bumwebumwe bwa chytrid buzwiho ingaruka ku bwoko bwibikeri, bimwe mubyukuri bitanga ingingo zingenzi zihagarara mubidukikije.
Umushakashatsi wa IGB, Dr. Ramsy Agha, yagize ati: “Mu kwanduza cyanobacteria, ibihumyo bya parasitike bizagabanya imikurire yabyo, bityo bigabanye ubukana n’uburabyo bw’uburozi bwa algal.”Ati: “Nubwo ubusanzwe dutekereza ko indwara ari ibintu bibi, parasite ni ingenzi ku bidukikije byo mu mazi Imikorere myiza ya sisitemu ni ingenzi cyane, kandi muri iki gihe ishobora no kugira ingaruka nziza.Abashakashatsi bongeyeho ko umwanda uterwa na fungiside ushobora kubangamira iki gikorwa gisanzwe.
Muri laboratoire, fungiside yubuhinzi penbutaconazole na azoxystrobin yapimwe na cyanobacteria yanduye chyle nuburabyo bwuburozi.Itsinda rishinzwe kugenzura naryo ryashinzwe kugereranya ingaruka.Mubitekerezo bishobora kugaragara kwisi, guhura kwa fungicide byombi bizavamo kugabanuka cyane kwandura parasite.
Ibisubizo byerekana ko ikoreshwa rya fungiside rishobora guteza imbere imikurire yangiza ya algae yangiza udukoko twangiza, kandi indwara ziterwa na fungal zishobora kugenzura imikurire yazo.
Ntabwo ari ubwambere imiti yica udukoko igira uruhare mu kubyara algae yangiza.Ubushakashatsi bwasohotse mu kinyamakuru Nature mu 2008 bwerekanye ko attriazine ya herbicide ishobora kwica mu buryo butaziguye algae yubusa, bityo bigatuma algae ifatanye idakura.Muri ubu bushakashatsi, abashakashatsi basanze izindi ngaruka kurwego rwibidukikije.Ubwiyongere bwa algae bufatika butera ubwiyongere bwabaturage b’ibisimba, bishobora kwanduza parasite ya amphibian.Kubera iyo mpamvu, udusimba twinshi nu mutwaro mwinshi wa parasite biganisha ku kwandura kwinshi mu baturage b’ibikeri byaho, bigatuma umubare w’abaturage ugabanuka.
Kurenga imiti yica udukoko turimo gukora kugirango tumenye ingaruka zidasobanutse ariko zikomeye kurwego rwibidukikije kurwego rwo gukoresha imiti yica udukoko.Nkuko twabigaragaje mu bushakashatsi bwashyizwe ahagaragara mu cyumweru gishize, ubushakashatsi bwagaragaje ko inyoni miliyari 3 zabuze kuva mu 1970, bingana na 30% by’abatuye Amerika.Raporo ntabwo ari raporo y’inyoni gusa, ivuga, Raporo ya Hookworms na cad igabanuka, ikora amoko ashingiye ku biribwa.
Nkuko umwe mu banditsi b'ubwo bushakashatsi, Dr. Justyna Wolinska yabigaragaje: “Mu gihe guhinga no kumenya ibihumyo byo mu mazi muri laboratoire z'ubumenyi bikomeje gutera imbere, gusuzuma ingaruka bigomba gutekereza ku ngaruka ziterwa na fungicide ku bihumyo byo mu mazi.”Ntabwo ari ngombwa gusuzuma gusa ibibazo byavuzwe nubushakashatsi buriho., Ariko nanone dukeneye gutekereza ku ngaruka zitaziguye zo gukoresha imiti yica udukoko.
Kubindi bisobanuro byukuntu imiti yica udukoko igira ingaruka kurubuga rwibiryo byose hamwe na ecosystem, reba Kurenga Pesticide.Gukoresha imiti yica udukoko bibangamira amoko nyamukuru muri ecosystem yose.
