Diflufenican carboxamide wakupha udzu poteteza mbewu

Mafotokozedwe Akatundu

Diflufenican ndi mankhwala opangidwa a gulu la carboxamide.Ili ndi gawo ngati xenobiotic, herbicide ndi carotenoid biosynthesis inhibitor.Ndi ether onunkhira, membala wa (trifluoromethyl)benzenes ndi pyridinecarboxamide.Amagwira ntchito ngati mankhwala otsalira komanso opha udzu omwe angagwiritsidwe ntchito isanameke komanso ikamera.Diflufenican ndi mankhwala opha tizilombo omwe amagwiritsidwa ntchito polimbana ndi namsongole, monga Stellaria media (Chickweed), Veronica Spp (Speedwell), Viola spp, Geranium spp (Cranesbill) ndi Laminum spp (Anakufa).Mayendedwe a diflufenican ndikuchita blekning, chifukwa choletsa carotenoid biosynthesis, kuletsa photosynthesis ndikupangitsa kufa kwa mbewu.Amagwiritsidwa ntchito kwambiri pa msipu wa clover, nandolo, mphodza, ndi lupins.Zasonyezedwa kuti zimapanga zotsatira pazitsulo zamagulu okhudzidwa a zomera zomwe zingakhale zodziimira pa zoletsa zake za carotenoid synthesis.Diflufenican imakhalabe yogwira ntchito kwa milungu ingapo ngati dothi lili ndi chinyezi chokwanira.Pawiriyi ndi yokhazikika mu yankho komanso motsutsana ndi zotsatira za kuwala ndi kutentha.Amagwiritsidwa ntchito m'dzinja ngati mankhwala ophera udzu wa dzinja

Zaloledwa kugwiritsidwa ntchito pa balere, durum tirigu, rye, triticale ndi tirigu.Itha kugwiritsidwa ntchito limodzi ndi isoproturon kapena mankhwala ena ophera udzu.

Diflufenican imakhala ndi kusungunuka kwamadzi pang'ono komanso kusinthasintha kochepa.Itha kukhala yosakhazikika m'nthaka kutengera momwe zinthu ziliri.Itha kukhalanso kulimbikira kwambiri m'madzi am'madzi kutengera momwe zinthu ziliri.Kutengera ndi mawonekedwe ake a physico-chemical sizimayembekezereka kutsika pansi pamadzi.Imawonetsa kawopsedwe wochuluka ku algae, kawopsedwe kakang'ono kwa zamoyo zina zam'madzi, mbalame ndi nyongolotsi.Ili ndi kawopsedwe kakang'ono kwa njuchi.Diflufenican imakhalanso ndi poizoni wochepa kwa nyama zoyamwitsa ngati itamwedwa ndipo imaganiziridwa kuti imakhumudwitsa.

Kugwiritsa Ntchito mbewu:
Lupins, minda, rye, triticale, balere yozizira ndi tirigu wachisanu.
