Mankhwala ophera tizilombo Fipronil 95% Tc CAS 120068-37-3
Tsatanetsatane wa Zamalonda
CAS: 120068-37-3
1.Fipronil, mankhwala otchedwa 5-amino-1- (2, 6 dichloro-4-trifluorotolyl) -4-trifluoromethyl-sulfinyl-pyrazole-3-carbonitrile, ndi benzopyrazole yoyamba yomwe imagwiritsidwa ntchito polimbana ndi tizilombo.kuyambira pomwe idapezeka mu 1987, yakhala ikugwiritsidwa ntchito kwambiri m'magawo ambiri monga ulimi ndi mankhwala a Chowona Zanyama, kukhala mtundu wolemera wa Chemicalbook wopha tizilombo.Fipronil, dzina lamalonda la Rexinte, ndi mtundu watsopano wa mankhwala ophera tizilombo a benzopyrazole, omwe ali ndi ubwino wambiri komanso mphamvu zambiri poyerekeza ndi mankhwala ophera tizilombo (organophosphates, pyrethroids, carbamates), ndipo amagwiritsidwa ntchito kwambiri m'minda yambiri yaulimi. mankhwala omwe amagwiritsidwa ntchito polimbana ndi tizirombo.
2.Fipronil makamaka imapangitsa Cl-flow mwa kutsekereza neural neural Cl-channel yomwe imayendetsedwa ndi γ-aminobutyric acid receptors, yomwe imayambitsa chisangalalo chachikulu cha dongosolo lamanjenje ndikupangitsa kufa kwa tizilombo, ndikukwaniritsa zotsatira za kupewa ndi kuwongolera tizirombo tosiyanasiyana tachuma. .
3.mp200.5～201℃, kachulukidwe wachibale 1.48～1.63, kuthamanga kwa nthunzi 3.73×10-7Pa(2.8×10-7Pa)(20℃).Kusungunuka: acetone 54.6g/100mL, dichloromethane 2.23g/Chemicalbook100mL, methanol 13.75g/100mL, hexane ndi toluene 0.3g/mL, madzi 1.9mg/L.Coefficient yogawa (octanol/madzi) 4.0.khola pansi pazikhalidwe zosungirako, theka la moyo m'madzi 135d, theka la moyo wa photolysis m'madzi 8h.
Kugwiritsa ntchito
1.Fluoropyrazole yomwe ili ndi tizilombo toyambitsa matenda, ntchito yaikulu, ntchito zambiri, ku Hemiptera, Compositae, Coleoptera, Lepidoptera ndi tizirombo tina ndi pyrethroids, mankhwala ophera tizilombo a carbamate apanga kukana tizilombo kumasonyezanso kukhudzidwa kwambiri.Itha kugwiritsidwa ntchito mu mpunga, thonje, masamba, soya, kugwiririra, fodya, mbatata, tiyi, manyuchi, chimanga, mtengo wa zipatso, nkhalango, thanzi la anthu, kuweta nyama, ndi zina zotere thonje, tizilombo tating'onoting'ono, njenjete zazing'ono zamasamba, njenjete za kabichi, njenjete za kale night, kakumbu, chodula mizu, bulb nematode, mbozi, udzudzu wamtengo wa zipatso, nsabwe za tirigu, coccid, trichoderma, ndi zina zotero. Mlingo wovomerezeka ndi 12.5~150g/ hm2 ndi.China yavomereza kuyeserera kogwira mtima kwamunda pa mpunga ndi ndiwo zamasamba.Kupanga ndi 5% kuyimitsidwa gel ndi 0.3% granule
2.Amagwiritsidwa ntchito kwambiri pa mbewu monga mpunga, nzimbe, mbatata, etc. Pazaumoyo wa nyama, amagwiritsidwa ntchito makamaka kupha tizilombo toyambitsa matenda monga utitiri ndi nkhupakupa pa amphaka ndi agalu.
