Kuti muchepetse kuwonongeka komwe kumayambitsidwa ndi tizirombo kwa mbewu, tapanga zipolowe zambiri. Njira yogwiritsira ntchito mankhwala osokoneza bongo ndi ofanana, ndiye kuti timasankha bwanji zomwe zili zoyenera kwambiri? Lero tikambirana za tizilombo tating'onoting'ono tomwe timachitanso zinthu ngati izi: IMidacloprid ndi Thiamethoxam.
Ife alimi tikudziwa bwino Indidacloprid, motero thiamethoxam ndi nyenyezi yatsopano matenda. Kodi zabwino zake ndi ziti pa m'badwo wachikulire?
01. Kusanthula kwa IMidacloprid ndi Thiamethoxam
Ngakhale njira ziwiri zochitikira ndizofanana (zitha kuyankha mwapakati pakati mwamanjenje a acetylcholineanthur system system, ntholtoxam ndi 5 yayikulu:
Thiamethoxam imagwira ntchito yambiri
Metabolite ya thiamethoxam mu tizilombo ndi katswiri, yemwe ali ndi ubale wapamwamba kwambiri chifukwa cholandirira tizilombo toyambitsa matenda a Acetylcholine kuposa thiamethoxam, motero ali ndi chidwi chachikulu;
Ntchito ya mankhwala a hydroxty metabolites a imidacloprid adachepetsedwa.
Thiamethoxam ali ndi solubility wakwera m'madzi
Kusungunuka kwa thiamethoxam m'madzi ndi nthawi 8 ku Immacloprid, kotero ngakhale pamalo ouma, sizikhudza mayamwidwe ndi kugwiritsa ntchito tirigu.
Kafukufuku wasonyeza kuti mu dothi lonyowa lokhazikika, thiamethoxam limawonetsanso mphamvu ngati imidacloprid; Koma m'malo osalala, nkwabwino kuposa Imidacloprid.
Kukana kwa Thiamethoxam
Popeza imidacloprid yakhala ikuyenda pafupifupi zaka 30, kukula kwa matenda ayamba kwambiri.
Malinga ndi malipoti, mphepo yamkuwa ya bulauni, thonje nsabwe ya thonje, ndi udzu wa udzu waponda unayamba kutsutsana nawo.
Chiwopsezo cha kukana pakati pa Thiamethoxam ndi IMidacloprid pa brawmoptopsparsrs, nsabwe za thonje ndi tizirombo tina ndizochepa kwambiri.
Thiamethoxam imatha kuwonjezera mbewu ndikulimbikitsa kukula kwa mbewu
Thiamethoxam ali ndi mwayi kuti kachiromboka sichingafanane ndi izi, ndiye kuti, zimakhudza mizu ndi mbande zolimba.
Kafukufuku wawonetsa kuti Thiamethoxam amatha kuyambitsa mapulongete osokoneza bongo, ndipo nthawi yomweyo amatulutsa oxin, cytokinin, absphenune, polysphenoase axidase, ndi pheroyanol aaseta mu mbeu. Zotsatira zake, thiamethoxam pa nthawi ya mbewu zimayambira ndipo mizu imathandizira kwambiri kupewa kupsinjika.
Thiamethoxam imatenga nthawi yayitali
Thiamethoxam ali ndi masamba olimba a tsamba ndi mizu ya muzu, ndipo wothandizirayo amatha msanga komanso wotanganidwa kwambiri.
Zikagwiritsidwa ntchito dothi kapena mbewu, thiamethoxam limayamwa mwachangu ndi mizu kapena maluwa atsopano, ndipo imayendetsedwa ndi mbali zonse za mbewu m'thupi lazomera. Imakhala mu thupi lomera kwa nthawi yayitali komanso osakhazikika pang'onopang'ono. Wosavala wosavalayo ali ndi matenda okwera, motero Thyamethoxam ali ndi vuto lalikulu kuposa imidacloprid.
