Yuav kom ntseeg tau tias cov khoom ua liaj ua teb zoo thiab muaj kev nyab xeeb, kev nyab xeeb ntawm ib puag ncig thiab kev nyab xeeb ntawm tib neeg lub neej, Ministry of Agriculture tau txiav txim siab raws li cov kev cai ntawm "Txoj Cai Kev Nyab Xeeb Khoom Noj ntawm Lub Tebchaws Suav" thiab "Cov Cai Tswjfwm Tshuaj Tua Kab Tsuag", tau tshuaj xyuas los ntawm Pawg Neeg Saib Xyuas Kev Sau Npe Tshuaj Tua Kab Tsuag Hauv Tebchaws, thiab raws li cov lus pom ntawm pej xeem. Cov kev ntsuas kev tswj hwm hauv qab no tau coj mus rau 8 hom tshuaj tua kab suav nrog 2,4-D-butyl ester, paraquat, dicofol, fenflurane, carbofuran, phorate, isofenphos methyl, thiab txhuas phosphide. Ntawm lawv, kev tswj hwm txhuas phosphide yog raws li nram no.
Txij li thaum Lub Kaum Hli 1, 2018, txwv tsis pub muag thiab siv cov khoom txhuas phosphide hauv lwm cov ntim khoom. Kev siv phosphorous chloride yog qhov txaus ntshai heev rau lub cev, vim tias txhuas phosphide raug lom los ntawm kev tsim cov phosphine hauv dej lossis kua qaub. Kev nqus pa ntawm cov pa phosphine tuaj yeem ua rau kiv taub hau, mob taub hau, qaug zog, tsis xav noj mov, mob hauv siab thiab mob plab sab saud. Hauv cov xwm txheej hnyav, muaj cov tsos mob ntawm lub hlwb lom, edema hauv lub hlwb, edema hauv lub ntsws, siab, raum thiab myocardial puas tsuaj, thiab mob plawv dhia tsis zoo. Kev noj qhov ncauj ua rau muaj kev lom phosphine, cov tsos mob ntawm txoj hnyuv plab, kub taub hau, txias, kiv taub hau, zoo siab, thiab mob plawv dhia tsis zoo. Hauv cov xwm txheej hnyav, muaj kev ua pa luv luv, oliguria, qaug dab peg, 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 tshuaj 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, Actellic (Baoan Valley) tau siv dav hauv thaj chaw suav nrog kev ua liaj ua teb, kev khaws cia, kev noj qab haus huv pej xeem, thiab kev cog ntoo txij li xyoo 1970. FAO/WHO Codex Alimentarius Commission tau tawm tswv yim tias cov seem ntawm pyrimidinhos-methyl yuav tsis ua rau muaj kev phom sij rau tib neeg mus sij hawm ntev; Lub Koom Haum Maritime Thoob Ntiaj Teb pom zoo tias pyrimidinhos-methyl tuaj yeem siv rau ntawm nkoj; British Brewing Association tau pom zoo pyrimiphos-methyl Siv rau kev tswj kab tsuag hauv kev khaws cia barley siv rau kev ua npias; lub koom haum pub tsiaj tau lees paub tias txawm tias nws yog cov nplej kho nrog pyrimidinhos ua ntej lossis tom qab sau qoob loo, nws tuaj yeem pub ncaj qha rau tsiaj; cov koob tshuaj pom zoo 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 feem ntau lub tebchaws. Baoan Valley tau siv zoo rau kev khaws cia thiab tiv thaiv cov khoom ua liaj ua teb hauv ntau dua 70 lub tebchaws thoob ntiaj teb. Cov nplej khaws cia, taum pauv qhuav, cov khoom noj mis nyuj, ntses qhuav, txiv hmab txiv ntoo qhuav, thiab lwm yam xav tau kev tswj hwm kab thiab kab laug sab luv luv lossis ntev. Baoangu yog suav tias yog cov tshuaj tua kab tsuag thoob ntiaj teb thiab zoo tshaj plaws.
Cov Lus Qhia:
(1) Ua cov khoom siv hauv tsev khaws khoom uas tsis muaj nplej. 1:50 dilution thiab txau kom sib npaug, txau 50 mL ntawm cov tshuaj diluted ib square meter.
(2) Ua cov nplej thiab cov khoom siv kho mob-sib tov hauv tag nrho lub tsev rau khoom. Ua ntej, sib tov thaum txau, thiab thaum kawg muab tso rau hauv qhov chaw cia khoom. Baoan Valley raug diluted 1: 100 thiab txau nrog 1 tuj ntawm cov nplej.
(3) Ua cov noob thiab cov khoom siv kho mob - sib tov saum npoo. Txheej saum npoo yog 30-100 cm, diluted, tsuag, thiab sib tov.
(4) Kev siv cov nplej thiab cov khoom siv kho mob - kev ua cov hnab ntim khoom. Dilute 1:50, thiab kho 1 lub hnab rau txhua 50 mL (cov hnab suav ua 0.5m × 1m).
Los ntawm qhov kev xav no, qhov kev hloov pauv ntawm pyrimidinhos methyl rau Aluminium phosphide yog ib qho 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 sib koom siab.
