kev siv sib xyaw
(1) Dimethoate thiab methamidophos yog sib xyaw nrog 40 feem pua dimethoate EC thiab 50 feem pua methamidophos hauv qhov piv ntawm 1: 1, qhia txog qee yam kev sib koom ua ke, thiab tiv thaiv thiab tswj cov paj rwb aphids uas tau tsim kev tiv thaiv rau dimethoate, paj rwb liab kab laug sab, thiab lwm yam. muaj cov kab mob ntau dua li dimethoate, zoo ib yam li methamidophos.
(2) Qhov sib tov ntawm dimethoate thiab dichlorvos yog 750mL ntawm 40 feem pua dimethoate EC ib hectare, thiab 375mL ntawm 80 feem pua dichlorvos EC, uas kuj muaj ib tug synergistic nyhuv ntawm resistant aphids thiab kab laug sab mites ntawm ntau yam zaub. .
(3) Kev sib xyaw siv cov tshuaj tua kab dimethoate thiab pyrethroid kuj qhia tau hais tias muaj kev sib koom ua ke zoo, uas tuaj yeem tswj tau cov aphids uas tiv taus dimethoate, thiab tseem tuaj yeem tswj cov kab ntsig kab ntsig, pob zeb diamondback npauj, paj rwb bollworm, paj rwb liab bollworms, kab laum, thiab lwm yam. .
Cov kev ceev faj
(1) Cov nroj tsuag xws li haus luam yeeb, jujube, txiv duaj, apricot, plum, txiv ntseej, fig, citrus, hops, compositae thiab sorghum yuav ua rau phytotoxicity. Ua phytotoxicity kuaj ua ntej, thiab tswj cov dilution yam hauv qab 1500 zaug.

Cov tshuaj tsuag ntsuab thiab cov nroj tsuag tsis tuaj yeem pub rau nyuj thiab yaj hauv 1 lub hlis, thiab cov teb uas tau siv tshuaj tsis tuaj yeem muab tso rau hauv 7-10 hnub. Nws yog tshuaj lom ntau rau lub plab ntawm cov nqaij qaib, thiab yuav tsum tau them nyiaj ntau dua thaum siv nws.
(3) Dimethoate yog tshuaj lom heev rau muv, thiab daim ntawv thov ntawm cov tshuaj yuav tsum zam qhov chaw tso muv.
(4) Dimethoate muaj tshuaj lom rau tib neeg thiab tsiaj txhu, tab sis tus nqi nkag mus rau tib neeg lub cev yog qhov loj heev, tshwj xeeb tshaj yog tias ua yuam kev, feem ntau ua rau mob hnyav heev.
(5) Dimethoate tsis tuaj yeem sib xyaw nrog cov tshuaj alkaline.
(6) Qhov siab tshaj plaws tso cai seem ntawm ntau yam khoom ua liaj ua teb pom zoo los ntawm kev sib koom ua ke ntawm Lub Koom Haum Khoom Noj thiab Kev Ua Liaj Ua Teb ntawm United Nations thiab World Health Organization: 2 mg / kg rau txiv hmab txiv ntoo thiab zaub; 1 mg / kg rau kua txob thiab txiv lws suav; 1 mg / kg rau strawberries.
