Kufotokozera kosavuta: mankhwala osasankha herbicides amapha mbewu zonse, mankhwala opha udzu amapha udzu wosafunikira komanso samapha mbewu zamtengo wapatali (kuphatikiza mbewu kapena malo obiriwira, etc.)
Kodi Selective Herbicides ndi chiyani?
Popopera mankhwala ophera udzu pa udzu wanu, namsongole wamtundu winawake amavulazidwa ndi mankhwala pamene udzu ndi zomera zomwe mukufuna sizikukhudzidwa.
Kusankha herbicides ndi njira yabwino mukawona udzu ukukula m'madera omwe mukufuna udzu ndi zomera, kotero simuyenera kudandaula za kupukuta mosamala ndi kupeza mankhwala pa udzu wanu ndikuwononga iwo.
Kusankha herbicides ndikosavuta kugwiritsa ntchito. Ingotsatirani malangizo olembedwa ndikusakaniza kusankha kwanu kwa herbicide ndi madzi mu chopopera cham'manja. Kenako mutha kuwaza pamitengo yomwe mukufuna kuchotsa!
Kupalira Mwakuthupi Kosankha
Polekanitsa mankhwala ophera udzu ku mbewu kapena mbewu zonse, mutha kulimbana ndi udzu wopopera mbewu mankhwalawa. Njira imodzi yabwino yochitira zimenezi ndi kupopera mankhwala mutabzala mbewu komanso namsongole.
Mankhwala Osankha Herbicides
Panthawiyi, mutha kupopera mankhwala a herbicide mwachindunji pa mbewu kapena m'munda popanda kudandaula kuti muwononge zomera zina. Kusankha kwenikweni kungatheke m'njira zitatu:
Physiologically, izi zikutanthauza kuti momwe zomera zimatengera mankhwala, zomera zomwe mukufuna kuchotsa zimatenga mankhwala mofulumira kuposa zomera zomwe simukuzifuna.
Mofologically, izi zikutanthawuza makhalidwe omwe udzu ungakhale nawo, monga mtundu wa masamba, kuphatikizapo masamba otambalala, atsitsi, ndi zina zotero.
Kagayidwe kachakudya, pamene zomera zomwe mukufuna kuziteteza zimatha kusokoneza mankhwala popanda kuwonongeka, namsongole sangathe.
Posankha mankhwala ophera udzu, ndikofunikira kudziwa ndikuwerenga malangizo mosamala kuti musawononge mbewu zomwe mukufuna kusunga. Kumbukirani kuti mphamvu ya herbicide imadalira nthawi yomwe mumagwiritsa ntchito komanso kuchuluka kwa momwe mumagwiritsira ntchito.
