Igihe cyiza cyo gutera imbere kiri murwego rwo kwinjira muri ingano, ni ukuvuga Ingano yimpeta zihindura icyatsi.
Igihe cyiza nicyiciro cyambere cyingano. Niba ikoreshwa hakiri kare, ingaruka zigenda zidashobora kuba ingirakamaro, ariko irashobora kuzana umusaruro wo kongera imbaraga;
Igihe cyiza no kwibanda kugirango ukoreshe chlorupquat chloride
Gushyira mu bikorwa chlorude ya chrlomequat hafi yicyumweru mbere yingano nigihe cyiza cyo kugera ku ngaruka nziza zo kugenzura imikurire no gukumira icumbi. Muri iki gihe, chloriaquat chloride irashobora kugabanya neza uburebure bwintangarugero munsi yingano. Ibisabwa byibanda kubiyobyabwenge ni 1,5 kugeza kuri garama 2 yibiyobyabwenge kuri litiro yamazi. Niba ingemwe z'ingano zikura cyane mu mpeshyi, garama 50 kugeza kuri 60 zimaze gukoreshwa kuri hegitari, kandi ibiro 30 by'amazi birashobora kongerwaho mugutererana; Niba ingemwe z'ingano zikura buhoro, garama 25 kugeza kuri 30 z'umukozi irashobora gukoreshwa kuri hegitari.
