Dimefluthrin Yogulitsa Yogwira Ntchito Pochotsa Tizilombo

Mafotokozedwe Akatundu

Mankhwala ophera tizilombo otchedwa pyrethroid omwe amagwira ntchito mwamphamvu polimbana ndi udzudzu ndi tizilombo tina. Dimefluthrin ndi yabwino kwambirimankhwala ophera tizilomboNdi madzi achikasu chopepuka mpaka a bulauni wakuda opanda zinthu zina zakunja, ndipo ndi chinthu chogwira ntchito bwino mu zofukiza zochotsa udzudzu. Chochepetsa ululu kapena poizoni muchozungulira cha udzudzuimagwiritsidwa ntchito poletsa ululu kapena kupha udzudzu, chifukwa mlingo wake ndi wochepa, kotero kuvulaza munthuyo ndi kochepa. Sili ndi poizoni pa nyama zoyamwitsa, ndipo silikhudzaZaumoyo wa Anthu Onse.

Kuzindikira zomwe zili mkati
Gwiritsani ntchito mpweya wa chromatography kuti mufufuze zomwe zili mu tetrafluoromethrin. Pogwiritsa ntchito fenpropathrin ngati muyezo wamkati, DB-1 quartz capillary column separation ndi FID detection. Zotsatira za kusanthula zikuwonetsa kuti linear correlation coefficient ya tetrafluoromethyl ether Chemicalbook pyrethroid ndi 0.9991, standard deviation ndi 0.000049, coefficient of variation ndi 0.31%, ndipo recovery rate ndi pakati pa 97.00% ndi 99.44%.

Kusamala

Ngati chipindacho chasuta ndi zofukiza zochotsa udzudzu kwa nthawi yayitali ndipo mpweya sukuyenda bwino, izi zingayambitse zizindikiro za kuuma pachifuwa ndi chizungulire kwa amayi apakati, kuchepetsa kuchuluka kwa mayendedwe a mwana wosabadwayo, komanso kuyambitsa hypoxia ya mwana wosabadwayo m'mimba. Chifukwa chake, ndi bwino kuti amayi apakati asagwiritse ntchito zophimba udzudzu.
