Txhawm rau kom txo cov kev puas tsuaj los ntawm kab kab tsuag rau cov qoob loo, peb tau tsim cov tshuaj tua kab sib txawv. Lub tshuab ntawm kev ua ntawm ntau cov tshuaj tua kab yog tib yam, yog li peb xaiv cov uas haum rau peb cov qoob loo? Niaj hnub no peb yuav tham txog ob cov tshuaj tua kab nrog cov hlau sib thooj ntawm kev nqis tes ua: imidacloprid thiab thiamasam.
Peb cov neeg ua liaj ua teb tau paub txog imidacloprid, yog li Thiametoxam yog lub hnub qub kab tshiab. Dab tsi yog nws qhov zoo dua cov laus dua?
01. Qhov sib txawv tsom xam ntawm imidacloprid thiab thiametoxam
Txawm hais tias ob lub tshuab ntawm kev nqis tes ua yog zoo sib xws (tuaj yeem xaiv cov kab conduction ntawm kab thiab tuag ntawm kab tuag), kev tuag ntawm cov kab tuag),
Thiamethoxam yog cov nquag ua haujlwm
Lub ntsiab metabolite ntawm thiamethoxam hauv kab yog Whianidin, uas muaj ib qho kev sib txawv rau cov kab acetylcholam, yog li nws muaj cov tshuaj tua kab mob ntau dua;
Cov kev ua si ntawm hydroxylated metabolites ntawm Imidaclofrid tau txo.
Thiamethoxam muaj cov solubility siab hauv dej
Lub solubility ntawm thiametoxam hauv dej yog 8 lub sij hawm uas ntawm imidaclopround, yog li txawm tias nyob rau hauv kev nqus ib puag ncig, nws tsis cuam tshuam nrog kev nqus thiab siv cov thiametoxam los ntawm nplej.
Cov kev tshawb fawb tau pom tias nyob rau hauv ib txwm noo noo, thiametholam qhia tau tias muaj kev tswj hwm zoo sib xws li imidacloprid; Tab sis nyob rau hauv cov kev mob uas npau taws, nws yog qhov zoo dua imidacloprid.
Tsawg thiametoxam tsis kam
Txij li thaum Imidacloprid tau nyob rau hauv kev ua lag luam rau ze li 30 xyoo, kev txhim kho ntawm cov kab tsis kam tau dhau los ua kev loj hlob loj.
Raws li cov lus tshaj tawm, cov xim av ya tawm, paj rwb aphid, thiab chival Larval Yoov tshaj cum tau tsim qee yam tiv thaiv rau nws.
Txoj kev pheej hmoo ntawm tus ntoo khaub lig-resistance ntawm Thiametoxam thiab Imidacloprofrid ntawm cov dav hlau xim av, paj rwb aphids thiab lwm yam kab tsuag tsis tshua muaj.
ThiajeSoxam tuaj yeem txhim kho cov qoob loo tiv thaiv thiab txhawb nqa qoob loo loj hlob
Thiametoxam muaj qhov zoo dua uas tau txais kev tshuaj kho tsis tau, uas yog, nws muaj qhov cuam tshuam ntawm kev txhawb nqa keeb kwm thiab muaj zog seedlings.
Cov kev tshawb fawb tau qhia tias TswvThoxam tuaj yeem ua kom tsob ntoo muaj kev ntxhov siab tsis kam tiv taus cov protein, polytokined accidase, thiab phenylalanine ammonia nyob rau hauv cov nroj tsuag. Raws li qhov tshwm sim, Thiametoxam hauv lem ua cov qoob loo stems thiab cov hauv paus hniav ntau dua thiab txhim kho kev ntxhov siab tiv thaiv.
Thiamethoxam kav ntev dua
Thiamethoxam muaj cov nplooj ntawv muaj zog thiab cov hauv paus systemicic, thiab tus neeg sawv cev tuaj yeem raug nrawm thiab nqus tau.
Thaum nws tau thov rau av lossis noob, Thiamethop tau sai sai los ntawm cov hauv paus hniav lossis thauj khoom tshiab rau txhua qhov chaw ntawm cov nroj tsuag lub cev los ntawm lub cev cog. Nws nyob qis qis hauv cov nroj tsuag lub cev ntev thiab txo qis qeeb. Cov tshuaj pleev cov khoom lag luam ua rau muaj cov tshuaj tua kab ntau dua, yog li Thiamethopas muaj cov nyhuv ntev dua li imidacloprid.
