Mchitidwe wa zochita za dinotefuran umatheka mwa kusokoneza kufalitsa kolimbikitsa mkati mwa dongosolo lamanjenje la tizilombo tomwe tikulimbana nalo pamene limalowa kapena kutenga chinthu chogwira ntchito m'thupi lake, zomwe zimapangitsa kuti asiye kudya kwa maola angapo pambuyo powonekera ndi imfa posakhalitsa.

Dinotefuran imatchinga njira zina za neural zomwe zimapezeka kwambiri mu tizilombo kuposa nyama zoyamwitsa.Ichi ndichifukwa chake mankhwalawa ndi owopsa kwa tizilombo kuposa anthu kapena agalu ndi amphaka.Chifukwa cha kutsekeka kumeneku, tizilombo timayamba kutulutsa acetylcholine (mankhwala ofunika kwambiri a neurotransmitter), zomwe zimapangitsa kufa ziwalo ndi imfa.

Dinotefuran imakhala ngati agonist pa tizilombo ta nicotinic acetylcholine receptors, ndipo dinotefuran imakhudza kumangidwa kwa nicotinic acetylcholine m'njira yosiyana ndi tizilombo tina ta neonicotinoid.Dinotefuran sichiletsa cholinesterase kapena kusokoneza njira za sodium.Chifukwa chake, machitidwe ake amasiyana ndi a organophosphates, carbamates ndi mankhwala a pyrethroid.Dinotefuran yasonyezedwa kuti imagwira ntchito kwambiri polimbana ndi mtundu wa whitefly wa silverleaf womwe sumva ku imidacloprid.

Ntchito ya Dinotefuran

Dinotefuran sikuti imangokhala ndi kawopsedwe komanso kawopsedwe ka m'mimba, komanso imakhala ndi mayamwidwe abwino kwambiri, kulowa mkati ndi ma conduction, omwe amatha kuyamwa mwachangu ndi tsinde, masamba ndi mizu.

Amagwiritsidwa ntchito kwambiri mu mbewu, monga tirigu, mpunga, nkhaka, kabichi, mitengo ya zipatso ndi zina zotero.

Imatha kuwongolera bwino tizirombo tosiyanasiyana, kuphatikiza tizirombo tapansi, tizirombo tapansi panthaka ndi tizirombo tina taukhondo.

Kugwiritsa Ntchito Njira

Zindikirani

1. Tikamagwiritsa ntchito dinotefuran ku Sericulture Area, tiyenera kusamala kuti tipewe kuipitsidwa mwachindunji kwa masamba a mabulosi ndikuletsa madzi oipitsidwa ndi furfuran kulowa m'nthaka ya mabulosi.

2. Kuopsa kwa mankhwala ophera tizilombo a dinotefuran ku njuchi kunkachokera pakatikati mpaka pa chiopsezo chachikulu, choncho kufalitsa mungu wa zomera kunali koletsedwa pa nthawi ya maluwa.
