1% I-Propoxur RB

[Izakhiwo]

I-crystalline powder emhlophe enephunga elincane elihlukile.

[Ukunyibilika]

Ukuncibilika emanzini ku-20°C cishe ku-0.2%. Iyancibilika kuma-solvents amaningi.

[Isebenzisa]

I-Propoxur iyi-systemic carbamate insecticide ethintana, isisu, nezindawo ezifuthayo. Ishaya ngokushesha, ngesivinini esiqhathaniswa nese-dichlorvos, futhi inomphumela ohlala isikhathi eside. Ibulala ama-ectoparasites, izinambuzane zasendlini (omiyane, izimpukane, amaphela, njll.), kanye nezinambuzane ezigcinwe endaweni yokugcina impahla. Isifutho sokumiswa esingu-1% ngethamo elingu-1-2 g lesithako esisebenzayo/imitha eyisikwele sisebenza kahle ekulawuleni izimbungulu ezibulalayo futhi sisebenza kangcono kune-trichlorfon uma sisetshenziswa ne-fly bait. Ukufakwa kokugcina ezitshalweni kufanele kube izinsuku ezingama-4-21 ngaphambi kokuvuna.

[Ukulungiselela noma Umthombo]

I-O-isopropylphenol incibilika ku-dioxane ephelelwe amanzi emzimbeni, futhi i-methyl isocyanate ne-triethylamine yengezwa nge-dropwise. Ingxube yokusabela iyashiswa kancane kancane futhi ipholiswe ukuvumela amakristalu ukuba adle. Ukwengeza i-petroleum ether kunciphisa ngokuphelele amakristalu, abese eqoqwa njenge-propoxur. I-byproduct urea igezwa nge-petroleum ether namanzi ukuze kukhishwe isincibilikisi, yomiswe ngaphansi kwengcindezi encishisiwe engu-50°C, futhi ifakwe kabusha ku-benzene ukuze ithole i-propoxur. Ukwakheka kufaka phakathi: umkhiqizo wezobuchwepheshe, onesithako esisebenzayo esingu-95-98%.

[I-Quota yokusetshenziswa (t/t)]

o-Isopropylphenol 0.89, methyl isocyanate 0.33, dehydrated dioxane 0.15, petroleum ether 0.50.

[Abanye]

Ayizinzile emithonjeni ye-alkaline enamandla, nengxenye yempilo yemizuzu engama-40 ku-pH 10 no-20°C. Ubuthi obuyingozi bomlomo LD50 (mg/kg): 90-128 kumagundane abesilisa, 104 kumagundane esifazane, 100-109 kumagundane abesilisa, kanye nama-40 kumaguinea pigs. I-acute dermal poisonity LD50 yamagundane abesilisa yi-800-1000 mg/kg. Ukondla amagundane abesilisa nabesifazane ukudla okuqukethe i-250 mg/kg ye-propoxur iminyaka emibili akuzange kube nemiphumela emibi. Ukondla amagundane abesilisa nabesifazane ukudla okuqukethe i-750 mg/kg ye-propoxur iminyaka emibili kwandise isisindo sesibindi kumagundane wesifazane, kodwa kwakungekho eminye imiphumela emibi. Inobuthi obukhulu ezinyosini. I-TLm (amahora angu-48) ku-carp ingaphezu kuka-10 mg/L. Izinga lensalela elivumelekile elayisini ngu-1.0 mg/L. I-ADI ingu-0.02 mg/kg.

[Izingozi Zezempilo]

Isibulala-zinambuzane esinobuthi obumaphakathi. Ivimbela umsebenzi we-red blood cell cholinesterase. Kungabangela isicanucanu, ukuhlanza, ukungaboni kahle, ukujuluka, ukushaya kwenhliziyo okusheshayo, nomfutho wegazi ophakeme. Kungase futhi kubangele i-contact dermatitis.

[Izingozi Zemvelo]

Kuyingozi emvelweni.

[Ingozi yokuqhuma]

Iyavutha futhi inobuthi.
