Muri iyi nkuru, Zsofia Sendre wo mu ishami ry’udukoko muri Kaminuza ya Leta ya Michigan yanditse ko udukoko dushyaimiti yica udukoko irwanya udukoko igenzura nezaInyenzi y’ibirayi ya Colorado hamwe n’izindi ndwara nyinshi z’ibirayi, biha abahinzi igikoresho gishya cy’agaciro cyo gushyira muri gahunda zabo zo kurwanya imiti yica udukoko.
Udukoko tw’ibirayi twa Colorado dukomeje kuba kimwe mu dukoko duto cyane tw’ibirayi. Ubu abahinzi bashobora gukoresha Zivalgo (fiazolin, ikoranabuhanga rya prazoline), umuti mushya wica udukoko duto dutanga igikoresho gishya cy’ingenzi cyo kurwanya udukoko tw’ibirayi twa Colorado.
Zivalgo ni umuti wica udukoko wo mu cyiciro cya 30, bivuze ko uburyo ukoreshwamo butandukanye n'ubundi bwoko bw'imiti yica udukoko bwemewe muri iki gihe mu kurwanya udukoko two mu bwoko bwa Colorado potato. Kubera ko udukoko two mu bwoko bwa Colorado potato twica udukoko tumaze igihe kinini turwanya imiti yica udukoko, kongeramo uburyo bushya bwo gukora ni ingenzi mu kurwanya udukoko. Guhinduranya ubwoko butandukanye bw'imiti yica udukoko mu gihe cy'ihinga bifasha gukomeza kugira umusaruro w'ibicuruzwa bihari.
Zivalgo irakora neza mu byiciro byose by’udukoko two mu bwoko bwa Colorado potato beetle kandi ishobora gukoreshwa mu gihe cyose cy’ihinga, guhera ku minsi 14 mbere y’isarura. Ariko, mu mirima yakoreshejwemo imiti yica udukoko mu gihe cyo gutera kugira ngo irwanye udukoko two mu gihe cy’itumba, Zivalgo muri rusange ikoreshwa neza mu kurwanya ikwirakwira ry’ibimera bikomeye mu mpeshyi, akenshi itangira mu ntangiriro za Nyakanga mu turere twinshi twa Michigan.
Kugira ngo urinde iyi miti mishya kandi ugabanye ubushobozi bwo kuyirwanya, irinde gukoresha Zivalgo mu gihe cy'itumba no mu gihe cy'impeshyi mu gihe kimwe.
