Iinkcukacha zeMveliso

CAS: 8003-34-7

I-1.I-Pyrethrins yizona zixhobo eziphambili zokulungiselela isiqhumiso seengcongconi, kwaye ziyizithako ezisebenzayo ze-insecticidal eziqulethwe kwi-pyrethrum, imifuno engapheliyo yentsapho yase-Asteraceae.Kukho ubukhulu becala i-pyrethrin I kunye ne-pyrethrin II, kwaye kukho kwakhona i-guaifenesin I kunye ne-guaifenesin II enesakhiwo esifanayo esinexabiso elincinci le-Chemicalbook.Okwangoku, iintlobo ngeentlobo zeekhompawundi ezifana neepyrethroids zendalo ziye zadityaniswa kwaye zisetyenziswa njengezibulali-zinambuzane, ngokudibeneyo ezaziwa ngokuba ziipyrethroids.

I-2.I-Pyrethrins zicatshulwa zeentyantyambo ze-chrysanthemum ezomisiweyo kwaye zisetyenziswa kakhulu njengezinambuzane zangaphakathi ngenxa yokuba zizinzile phantsi kobushushu kunye neemeko zokukhanya.Ezinye iishampu ezibulala iintwala zentloko zikwanazo neepyrethrins.I-Pyrethroids yenziwe ngesiseko se-pyrethroids kunye nomsebenzi we-biological, kwaye ukuzinza kwabo kuye kwanda.Ubukhulu becala bohlulwe kuhlobo lwe-I kunye nohlobo lwe-II, kwaye uhlobo lwe-II lunetyhefu ngakumbi kunohlobo lwe-I. I-Chemicalbook synthetic pyrethroids isetyenziswa kakhulu kwezolimo kunye ne-horticulture ukubulala izitshabalalisi zokwakha (ezifana neentubi), iintwala kunye neentakumba.Iipyrethroids kunye ne-synthetic pyrethroids zinokungena ngokukhawuleza kwizinambuzane kwaye zibakhubaze.I-Permethrin sisitshabalalisi esiphandiweyo sakwangoko se-pyrethroid esingaqulathanga isakhiwo se-cyano, kwaye yayiyeyokuqala kwizibulali-zinambuzane zepyrethroid ukuvela njengesitshabalalisi esizinzile sokukhanya esilungele ukulawula izitshabalalisi zezolimo.

3.Pyrethrum (igama lesayensi: Pyrethrum cinerariifolium Trev.) lilungu losapho lweCompositae.Wazalelwa eYurophu.IShaanxi, iShandong, iHeilongjiang, iJilin, iLiaoning, iJiangsu, iZhejiang, iAnhui, iJiangxi, iHunan, iSichuan, iGuangdong neYunnan zonke zilinywa eTshayina.
I-Pyrethrum iqulethe i-0.6-1.3% yepyrethrin kunye ne-grimethrin kwiintyatyambo zayo.I-Pyrethrin, ekwabizwa ngokuba yi-pyrethrin, lulwelo olunamafutha e-viscous olusetyenziswa ngokuqhelekileyo njengesibulali-zinambuzane.

Isicelo

1.I-Pyrethroid sisibulali-zinambuzane esibanzi esikwaziyo ukulawula iintlobo ngeentlobo zezinambuzane ezitshabalalisayo.I-insecticidal virulence yayo i-10 kumaxesha e-100 aphezulu kunexesha elidala lezinambuzane ezifana ne-organic chlorine, i-organic phosphorus kunye ne-carbamate.Indlela yokusebenza kwayo kukuphazamisa i-physiology eqhelekileyo yeentsholongwane zezinambuzane, ezibangela ukuba zife ngenxa yolonwabo, ukukhubazeka kunye nokukhubazeka.IiPyrethroids zikhuselekile ebantwini nakwizilwanyana ngenxa yedosi yazo encinci kunye nokugxila okuphantsi, kwaye zinongcoliseko oluncinci lokusingqongileyo.

I-2.I-Pyrethroids inokubangela ukuchithwa okuncinci kwe-membrane ye-nerve cell ku-organism, ukwandisa i-compound emva-enokwenzeka, ukukhokelela ekugqithiseni okuphindaphindiweyo emva kokukhutshwa, kuchaphazela iziteshi ze-Na + kunye ne-K +, ukuvimba i-motor motor ye-Chemicalbook isikhundla kwaye kubangele ubuthi beenwele.I-Pyrethroid potentiators inokuthintela kwaye ilibazise imetabolism yepyrethroids emzimbeni, iphucule ubuthi bayo kwaye yandise ixesha lesenzo seziyobisi emzimbeni ukwandisa ukusebenza.
