Pulogalamu yatsopano yogwiritsira ntchito mankhwala ophera tizilombo polimbana ndi kachilombo ka mbatata ku Colorado.

Munkhaniyi, Zsofia Sendre wa Dipatimenti ya Zachilengedwe ku Michigan State University akulemba kuti zatsopanomankhwala ophera tizilombo amalamulira bwino mankhwala ophera tizilombokachilombo ka mbatata ka ku Colorado ndi tizilombo tina ta mbatata, zomwe zimapatsa alimi chida chatsopano chamtengo wapatali chogwiritsira ntchito mu mapulogalamu awo othana ndi mankhwala ophera tizilombo.

Kambuku wa mbatata wa ku Colorado akadali mmodzi mwa tizilombo toopsa kwambiri ta mbatata. Alimi tsopano akhoza kugwiritsa ntchito Zivalgo (fiazolin, ukadaulo wa prazoline), mankhwala atsopano ophera tizilombo omwe amapereka chida chatsopano chofunikira chothana ndi kachilombo ka mbatata ka ku Colorado.
Zivalgo ndi mankhwala ophera tizilombo a Class 30, zomwe zikutanthauza kuti njira yake yogwirira ntchito imasiyana ndi mankhwala ena ophera tizilombo omwe avomerezedwa kuti athetse kachilombo ka Colorado potato. Popeza kachilombo ka Colorado potato kakhala kakulimbana ndi mankhwala ophera tizilombo kwa nthawi yayitali, kuwonjezera njira yatsopano yogwirira ntchito ndikofunikira kwambiri polimbana ndi matenda. Kusinthasintha mitundu yosiyanasiyana ya mankhwala ophera tizilombo nthawi ya kukula kumathandiza kuti zinthu zomwe zilipo zigwire ntchito bwino.

Zivalgo ndi yothandiza kwambiri polimbana ndi magawo onse a kachilomboka ka mbatata ka ku Colorado ndipo ingagwiritsidwe ntchito nthawi yonse yobzala, kuyambira masiku 14 isanakololedwe. Komabe, m'minda momwe mankhwala ophera tizilombo ankagwiritsidwa ntchito pobzala kuti athetse tizilombo tomwe timakhala m'nyengo yozizira, Zivalgo nthawi zambiri imagwiritsidwa ntchito bwino poletsa kumera kwa akuluakulu m'chilimwe, chomwe nthawi zambiri chimayamba kumayambiriro kwa Julayi m'madera ambiri ku Michigan.
Kuti muteteze mankhwala atsopanowa ndikuchepetsa kukula kwa kukana, pewani kugwiritsa ntchito Zivalgo pa nthawi yozizira kwambiri komanso nthawi yachilimwe yomweyi.
