Mafotokozedwe Akatundu

Trifluralin ndi mankhwala omwe amagwiritsidwa ntchito kwambiri asanatuluke.Trifluralin nthawi zambiri amagwiritsidwa ntchito panthaka kuti athe kuwongolera mitundu yosiyanasiyana ya udzu wapachaka ndi udzu.Imalepheretsa kukula kwa mizu mwa kusokoneza mitosis, motero imatha kuletsa udzu pamene ukumera.Poletsa meiosis ya chomera, trifluralin imalepheretsa mizu ya mmera kukula, motero imaletsa kumera kwa udzu.Trifluralin amagwiritsidwa ntchito kwambiri kuchotsa udzu m'minda ya thonje, soya, zipatso, ndi masamba ena.Mankhwala ena atha kugwiritsidwa ntchito kunyumba poletsa udzu ndi mbewu zosafunikira m'munda.

Trifluralin ndi mankhwala osankhika, osankhidwa asanatuluke a dinitroaniline omwe ayenera kuphatikizidwa m'nthaka pogwiritsa ntchito makina mkati mwa maola 24 atagwiritsidwa ntchito.Mankhwala opha udzu asanamere mbande amathiridwa udzu usanamere.Mapangidwe a granular akhoza kuphatikizidwa ndi kuthirira pamwamba.Trifluralin ndi mankhwala opangira dothi osankha omwe amagwira ntchito polowa mbande m'chigawo cha hypocotyls ndikusokoneza magawano a cell.Zimalepheretsanso kukula kwa mizu.

Angagwiritsidwe ntchito thonje, soya, nandolo, kugwiririra, mtedza, mbatata, yozizira tirigu, balere, Kasitolo, mpendadzuwa, nzimbe, masamba, mitengo ya zipatso, etc., makamaka ntchito kupewa kuchotsa monocotyledonous namsongole ndi pachaka yotakata-leaved namsongole, monga udzu wa barnyard, thrush yayikulu, matang, udzu wa dogtail, udzu wa cricket, udzu wokhwima, golide zikwi, udzu wa ng'ombe, udzu wa tirigu, oats zakutchire, ndi zina zotero, komanso kuteteza kuchotsedwa kwa mbewu zazing'ono za purslane, wisps ndi namsongole wina wa dicotyledonous.Sichigwira ntchito kapena sichigwira ntchito polimbana ndi namsongole osatha monga mpendadzuwa wa dragon, khutu la nzimbe ndi amaranth.Osagwira ntchito motsutsana ndi udzu wamkulu.Manyowa, mapira ndi mbewu zina zovutirapo sizingagwiritsidwe ntchito;Beets, tomato, mbatata, nkhaka, ndi zina zotero sizotsutsa kwambiri.

Amagwiritsidwa ntchito ndi linuron kapena isoproturon poyang'anira udzu wapachaka ndi namsongole wamasamba ambiri m'nyengo yozizira.Nthawi zambiri amagwiritsidwa ntchito kubzala chisanadze ndi kuphatikiza nthaka.

Trifluralin imagwira ntchito m'nthaka.Kumera kwa mbewu kungakhudzidwe kwa zaka 1* mutabzala nthaka, makamaka m'malo owuma.Nthawi zambiri sichimatengedwa m'nthaka ndi zomera.
