Product Description
Nws ua haujlwm hauv qab pH 5.0.Nws yooj yim rau hydrolysis thiab tsis ua haujlwm siab tshaj pH 7.0.Nws decomposes sai heev thaum pH siab tshaj 12. Nws kuj tseem tuaj yeem txhawb kev decomposition thaum nws ntsib hlau, txhuas, thiab hlau.Stable rau lub teeb, tab sis me ntsis ruaj khov rau cua sov.Isomerization tshwm sim thaum rhuab ntawm chav tsev kub, thiab 90% hloov mus rau hauv methylthio isomer thaum rhuab ntawm 150 ℃ rau 24 teev.
●Biochemistry:
Cholinesterase inhibitor. Proinsecticide, qhib los ntawm metabolic oxidative desulfuration rau cov oxon coj.Hom kev ua: Cov tshuaj tua kab tsis muaj kab mob thiab acaricide nrog kev sib cuag, plab, thiab ua pa ua pa.
●Kev siv:
Siv los tswj Coleoptera, Diptera, Hemiptera, Hymenoptera thiab Lepidoptera hauv ntau hom qoob loo, suav nrog paj rwb, pome, mos thiab pob zeb txiv hmab txiv ntoo, qos yaj ywm, mov thiab zaub.Siv dav los tswj cov kab mob arthropod loj (Culicidae) hauv cov phiaj xwm kev noj qab haus huv pej xeem, ectoparasites (Diptera, Acari, Mallophaga) ntawm nyuj, nqaij qaib, dev thiab miv, tib neeg lub taub hau thiab lub cev ntshauv (Anoplura), kab hauv tsev (Diptera, Orthoptera), thiab rau kev tiv thaiv ntawm cov nplej khaws cia.
●Phytotoxicity:
Tsis yog-phytotoxic feem ntau, yog siv raws li kev pom zoo, tab sis glasshouse cucurbits thiab taum, tej yam ornamentals, thiab ib co ntau yam ntawm txiv apples, pear, thiab grapes yuav raug mob.
●Compatibility:
Tsis sib haum nrog cov ntaub ntawv alkaline (cov tshuaj lom neeg seem yuav raug txo qis).
●Plaub:
Non-systemic broad-spectrum insecticides muaj kev sib cuag zoo thiab qee yam fumigation cuam tshuam.Tom qab nkag mus rau hauv lub cev kab, lawv yog thawj zaug oxidized rau ntau cov tshuaj lom Malathion, uas exerts ib tug haib lom nyhuv.Hauv cov tsiaj ntshav sov, nws yog hydrolyzed los ntawm carboxylesterase, uas tsis pom nyob rau hauv kab, thiab yog li poob toxicity.Malathion muaj toxicity tsawg thiab luv luv residual nyhuv.Nws muaj txiaj ntsig zoo tiv thaiv kev tho thiab nqus qhov ncauj thiab zom qhov ncauj.Nws yog qhov tsim nyog rau kev tswj cov kab tsuag xws li luam yeeb, tshuaj yej thiab mulberry ntoo, thiab tuaj yeem siv los tswj cov kab tsuag hauv tsev.
●Kev phom sij:
Nws yog combustible nyob rau hauv cov ntaub ntawv ntawm qhib nplaim taws thiab kub kub.Reacts nrog muaj zog oxidants.Decompose los ntawm tshav kub los tiv thaiv kev tsim cov phosphorus thiab sulfur oxide gases.
●Toxicity:
Tsawg toxicity
●Ntim hauv 250KG / Nruas
