Pofuna kuonetsetsa kuti zinthu zaulimi zili bwino komanso zotetezeka, chitetezo cha chilengedwe komanso miyoyo ya anthu, Unduna wa Zaulimi unaganiza motsatira mfundo zoyenera za “Lamulo Loteteza Chakudya la People's Republic of China” ndi “Malamulo Oyendetsera Zilonda Zophera”, zomwe zawunikidwa ndi Komiti Yowunikira Kulembetsa Zilonda Zophera, komanso kutengera ndemanga za anthu. Njira zotsatirazi zoyendetsera zikugwiritsidwa ntchito pa mankhwala ophera tizilombo 8 kuphatikizapo 2,4-D-butyl ester, paraquat, dicofol, fenflurane, carbofuran, phorate, isofenphos methyl, ndi aluminium phosphide. Pakati pawo, kayendetsedwe ka aluminium phosphide ndi motere.
Kuyambira pa 1 Okutobala, 2018, n'koletsedwa kugulitsa ndikugwiritsa ntchito zinthu zopangidwa ndi aluminiyamu phosphide m'maphukusi ena. Kugwiritsa ntchito phosphorous chloride ndikovulaza thupi kwambiri, chifukwa aluminiyamu phosphide imayikidwa poizoni chifukwa cha kupanga phosphine m'madzi kapena asidi. Kupuma mpweya wa phosphine kungayambitse chizungulire, mutu, kutopa, kusowa chilakolako cha chakudya, kuuma pachifuwa ndi kupweteka kwa m'mimba. Pa milandu yoopsa, pali zizindikiro za poizoni m'maganizo, kutupa kwa ubongo, kutupa kwa m'mapapo, kuwonongeka kwa chiwindi, impso ndi mtima, komanso matenda a mtima. Kumwa pakamwa kumabweretsa poizoni wa phosphine, zizindikiro za m'mimba, malungo, kuzizira, chizungulire, kusangalala, ndi kusokonezeka kwa mtima. Pa milandu yoopsa, pali kupuma movutikira, oliguria, kugwedezeka, kugwedezeka, ndi chikomokere.
Pa 2 Marichi, 2015, WHO idatulutsa mndandanda watsopano wa mankhwala ophera tizilombo ndi mankhwala omwe akulimbikitsidwa kupopera m'nyumba kuti apewe ndikulamulira matenda a malungo, kuphatikizapo pyrimiphos-methyl. Pa pyrimidinhos methyl, Actellic (Baoan Valley) yakhala ikugwiritsidwa ntchito kwambiri m'madera kuphatikizapo ulimi, malo osungiramo zinthu, thanzi la anthu, ndi nkhalango kuyambira 1970. FAO/WHO Codex Alimentarius Commission yapereka lingaliro lakuti zotsalira za pyrimidinhos-methyl sizingayambitse zoopsa kwa anthu kwa nthawi yayitali; International Maritime Organisation ikulangiza kuti pyrimidinhos-methyl ingagwiritsidwe ntchito pa zombo; British Brewing Association yavomereza pyrimiphos-methyl Yogwiritsidwa ntchito poletsa tizilombo posungira barele wogwiritsidwa ntchito popanga mowa; bungwe lodyetsa ziweto latsimikizira kuti kaya ndi tirigu wothandizidwa ndi pyrimidinhos isanakololedwe kapena itatha kukolola, ikhoza kuperekedwa mwachindunji kwa ziweto; mlingo woyenera wa pyrimidinhos umagwiritsidwa ntchito pochiza zinthu zaulimi. Yagwiritsidwa ntchito mokwanira komanso yovomerezeka mu malonda apadziko lonse lapansi amayiko ambiri. Chigwa cha Baoan chagwiritsidwa ntchito bwino posungira ndi kuteteza zinthu zaulimi m'maiko opitilira 70 padziko lonse lapansi. Mbewu zosungidwa, tofu zouma, mkaka, nsomba zouma, zipatso zouma, ndi zina zotero zimafuna kuwongolera tizilombo ndi nthata kwa kanthawi kochepa kapena kwa nthawi yayitali. Baoangu imaonedwa ngati mankhwala ophera tizilombo padziko lonse lapansi komanso abwino kwambiri osungira.
Malangizo:
(1) Kukonza zinthu zopanda tirigu m'nyumba yosungiramo zinthu. Kusungunula 1:50 ndi kupopera mofanana, kupopera 50 mL ya yankho losungunuka pa mita imodzi.
(2) Kukonza tirigu ndi mankhwala - kusakaniza mu nyumba yonse yosungiramo zinthu. Yesani kaye, sakanizani mukamapopera, kenako potsiriza muike mu malo osungira. Baoan Valley imachepetsedwa ndi 1:100 ndikupopera tani imodzi ya tirigu.
(3) Kukonza tirigu ndi mankhwala - kusakaniza pamwamba. Gawo la pamwamba ndi 30-100 cm, lochepetsedwa, lopopera, ndi losakanizidwa.
(4) Kusamalira tirigu ndi zinthu zamankhwala - kukonza matumba opakira. Sakanizani 1:50, ndipo perekani thumba limodzi pa 50 mL (matumbawo amawerengedwa ngati 0.5m×1m).
Kuchokera pa mfundo imeneyi, kusintha kwa pyrimidinhos methyl m'malo mwa Aluminium phosphide ndi chinthu chotetezeka komanso chodalirika, ndipo zotsatira za kugwiritsa ntchito pyrimidinhos methyl ndi zabwino kwambiri, zomwe zayamikiridwa ndi onse.
