Txhawm rau kom muaj kev nyab xeeb thiab nyab xeeb ntawm cov khoom ua liaj ua teb, kev nyab xeeb ntawm ecological ib puag ncig thiab kev nyab xeeb ntawm tib neeg lub neej, Ministry of Agriculture txiav txim siab raws li cov kev cai ntawm "Food Safety Law of the People's Republic of China" thiab "Txoj Cai Tswj Tshuaj Kab Tsuag", txheeb xyuas los ntawm Pawg Saib Xyuas Tshuaj Tiv Thaiv Kab Mob Hauv Tebchaws, thiab raws li cov lus pom rau pej xeem. Cov kev tswj xyuas hauv qab no yog siv rau 8 tshuaj tua kab xws li 2,4-D-butyl ester, paraquat, dicofol, fenflurane, carbofuran, phorate, isofenphos methyl, thiab txhuas phosphide. Ntawm lawv, kev tswj hwm ntawm aluminium phosphide yog raws li hauv qab no.
Txij Lub Kaum Hli 1, 2018, nws raug txwv tsis pub muag thiab siv cov khoom siv txhuas phosphide hauv lwm lub ntim. Kev siv cov phosphorous chloride ua rau lub cev muaj kev phom sij heev, vim tias txhuas phosphide raug tshuaj lom los ntawm kev tsim cov phosphine hauv dej lossis kua qaub. Kev nqus pa ntawm phosphine tuaj yeem ua rau kiv taub hau, mob taub hau, qaug zog, tsis qab los noj mov, hauv siab nruj thiab mob plab. Hauv cov xwm txheej hnyav, muaj cov tsos mob ntawm kev puas siab puas ntsws, cerebral edema, pulmonary edema, daim siab, lub raum thiab myocardial puas, thiab lub plawv dhia tsis zoo. Kev tswj qhov ncauj ua rau muaj phosphine lom, cov tsos mob ntawm plab hnyuv, ua npaws, ua daus no, kiv taub hau, zoo siab, thiab ua rau lub plawv dhia tsis zoo. Hauv cov xwm txheej hnyav, ua tsis taus pa, oliguria, convulsions, poob siab, thiab coma.
Thaum Lub Peb Hlis 2, 2015, WHO tau tshaj tawm cov npe tshiab ntawm cov tshuaj tua kab thiab cov qauv uas pom zoo rau kev txau sab hauv tsev kom tiv thaiv thiab tswj cov kab mob malaria, suav nrog pyrimiphos-methyl. Rau pyrimidinhos methyl, Actellik (Baoan Valley) tau siv dav hauv thaj chaw suav nrog kev ua liaj ua teb, chaw cia khoom, kev noj qab haus huv pej xeem, thiab hav zoov txij li xyoo 1970. FAO / WHO Codex Alimentarius Commission tau hais tias cov seem ntawm pyrimidinhos-methyl yuav tsis ua rau lub sijhawm ntev. toxicological txaus ntshai rau tib neeg; Lub koom haum International Maritime pom zoo tias pyrimidinhos-methyl tuaj yeem siv rau hauv nkoj; Lub koom haum British Brewing tau pom zoo pyrimiphos-methyl Siv rau kev tswj kab tsuag hauv kev khaws cia barley siv rau brewing; tsiaj pub lub koom haum paub tseeb tias txawm nws yog nplej kho nrog pyrimidinhos ua ntej los yog tom qab sau, nws tuaj yeem ncaj qha pub rau tsiaj; qhov pom zoo npaum li cas ntawm pyrimidinhos yog siv los kho cov khoom ua liaj ua teb Nws tau siv tag nrho thiab lees txais hauv kev lag luam thoob ntiaj teb ntawm ntau lub teb chaws. Baoan Valley tau ntse siv rau kev khaws cia thiab kev tiv thaiv cov khoom ua liaj ua teb hauv ntau tshaj 70 lub teb chaws thoob ntiaj teb. Khaws cov nplej, qhuav taum pauv, cov khoom noj siv mis, ntses qhuav, txiv hmab txiv ntoo qhuav, thiab lwm yam. yuav tsum tau siv sijhawm luv lossis ntev tswj cov kab thiab mites. Baoangu yog suav tias yog lub ntiaj teb thiab zoo heev khaws cov tshuaj tua kab.
Cov lus qhia:
(1) Kev ua cov khoom lag luam tsis muaj cov khoom lag luam. 1:50 dilution thiab tusyees stagnant tshuaj tsuag, tsuag 50 mL ntawm diluted tov ib square meter.
(2) Kev ua cov nplej thiab cov khoom siv tshuaj-sib xyaw hauv tag nrho lub tsev rau khoom. Qhov hnyav ua ntej, sib tov thaum txau, thiab thaum kawg muab tso rau hauv cia. Baoan Valley yog diluted 1:100 thiab txau nrog 1 tuj nplej.
(3) Ua cov nplej thiab cov khoom siv tshuaj-kev sib xyaw ua ke. Cov txheej saum npoo yog 30-100 cm, diluted, txau, thiab sib tov.
(4) Kev tuav cov nplej thiab cov khoom siv tshuaj-ua cov hnab ntim khoom. Dilute 1:50, thiab kho 1 sacks rau 50 mL (cov hnab yog xam raws li 0.5m × 1m).
Los ntawm qhov kev pom no, kev hloov pauv ntawm pyrimidinhos methyl rau Aluminium phosphide yog qhov muaj kev nyab xeeb thiab txhim khu kev qha, thiab cov nyhuv ntawm kev siv pyrimidinhos methyl yog qhov zoo heev, uas tau txais kev qhuas zoo.
