Yuav ua li cas cais Insecticides los ntawm qhov chaw
Nws tuaj yeem muab faib ua:
①Inorganic thiab mineral Insecticides. Xws li txhuas arsenate, calcium arsenate, sodium fluorosilicate thiab ntxhia roj emulsion. Xws li Insecticides feem ntau muaj qhov ua tau zoo thiab yooj yim ua rau phytotoxicity rau cov qoob loo, thaum arsenic muaj tshuaj lom rau tib neeg. Yog li ntawd, feem ntau ntawm lawv tau raug tshem tawm txij li qhov loj-scale siv cov organic hluavtaws Insecticidess.
②Plant Insecticidess tsim los ntawm Insecticides manufacturers. Muaj txog 1,000 hom nroj tsuag hauv ntiaj teb uas muaj ntau dua lossis tsawg dua rau kab. Kev siv dav yog pyrethrum, ntses vine thiab luam yeeb. Tsis tas li ntawd, qee cov nroj tsuag kuj muaj cov tshuaj nquag zoo ib yam li cov menyuam yaus cov tshuaj hormones, precocious hormone, thiab ecdysone. Piv txwv li, camptothecin cais tawm ntawm cov cag ntoo, tawv ntoo lossis txiv hmab txiv ntoo ntawm Camptotheca muaj cov nyhuv tsis zoo rau Masson Pine kab ntsig.
③ Organic hluavtaws Insecticides tsim los ntawm Insecticides manufacturers. Xws li organochlorine DDT, 666, endosulfan, toxaphene, thiab lwm yam., DDT, 666 yog ob yam tshuaj tua kab nrog cov khoom siv loj thiab dav siv, tab sis vim lawv yooj yim tsub zuj zuj hauv kab mob, txij li xyoo 70s ntawm lub xyoo pua 20th txij li thaum pib ntawm 1990s, nws tau raug txwv los yog txwv nyob rau hauv ntau lub teb chaws; Ntau tshaj 400 ntau yam ntawm organophosphorus parathion, trichlorfon, dimethoate, thiab lwm yam, thiab cov khoom tso tawm yog thawj zaug ntawm cov tshuaj tua kab; carbamate carbamic acid, carbofuran, thiab lwm yam.; pyrethroids xws li fenvalerate, deltamethrin, thiab lwm yam.;
④ Cov tshuaj tua kab tshuaj tua kab. Insecticide manufacturers xws li ntau yam ntawm cov menyuam yaus cov tshuaj hormones, pheromone analogs, thiab lwm yam. (saib cov tshuaj tua kab Insecticidess).
Cov txheej txheem ntawm kev txiav txim ntawm ob peb tshuaj Insecticides, xws li cov ntxhia roj emulsions, feem ntau ua rau lub cev nto, thaum feem coob ntawm cov organic hluavtaws Insecticidess nkag mus rau hauv lub cev ntawm cov kab tsuag, cuam tshuam los yog rhuav tshem ib txwm physiological thiab biochemical tshuaj nyob rau hauv tej qhov chaw. Txoj kev nkag mus rau hauv lub cev ntawm cov kab tsuag, ib txhia nkag mus rau hauv lub plab zom mov los ntawm lub qhov ncauj nrog cov zaub mov, infiltrate mus rau hauv cov ntshav, ib txhia kis mus rau lub epidermis, thiab ib txhia kis mus rau lub stomata thiab trachea. Txo cov tshuaj thiab poob nws qhov kev ua phem, tab sis qee cov tshuaj tau qhib los txhim kho cov kab mob, thiab cov tshuaj uas tsis tau degraded (los yog activated compounds) plays lub luag hauj lwm lom nyob rau hauv tej qhov chaw vim muaj ntau yam mechanisms ntawm kev ua, xws li ua yeeb yam ntawm cov tshuaj. paj hlwb los yog hauv intracellular respiration thiab metabolism.
