Kuti zvive nechokwadi chekuti zvigadzirwa zvekurima zvine mhando uye zvakachengeteka, kuchengetedzwa kwezvakatipoteredza uye kuchengetedzeka kwehupenyu hwevanhu, Bazi rezvekurima rakasarudza zvichienderana ne "Mutemo weKuchengetedzwa kweChikafu wePeople's Republic of China" uye "Mitemo yeKutarisira Zvipembenene", yakaongororwa neNational Pesticide Registration Review Committee, uye zvichibva pane zvakataurwa neveruzhinji. Matanho anotevera ekutarisira anotorwa pamishonga 8 yezvipembenene inosanganisira 2,4-D-butyl ester, paraquat, dicofol, fenflurane, carbofuran, phorate, isofenphos methyl, uye aluminium phosphide. Pakati pazvo, kutarisira aluminium phosphide ndekwekuti:
Kubva Gumiguru 1, 2018, hazvibvumidzwe kutengesa nekushandisa zvigadzirwa zvealuminium phosphide mune mamwe mapakeji. Kushandiswa kwephosphorus chloride kunokuvadza muviri zvikuru, nekuti aluminium phosphide inochetura nekuda kwekugadzirwa kwephosphine mumvura kana acid. Kufema gasi rephosphine kunogona kukonzera dzungu, musoro, kuneta, kurasikirwa nechido chekudya, kuoma kwechipfuva uye kurwadziwa kwemudumbu. Muzviitiko zvakakomba, pane zviratidzo zvepfungwa zvine chepfu, kuzvimba kweuropi, kuzvimba kwemapapu, kukuvara kwechiropa, itsvo nemoyo, uye matambudziko emoyo. Kunwa nemuromo kunokonzera chepfu yephosphine, zviratidzo zvemudumbu, fivha, kutonhora, dzungu, kufara, uye kusagadzikana kwemoyo. Muzviitiko zvakakomba, pane kufema kushoma, oliguria, pfari, shock, uye coma.
Musi wa2 Kurume, 2015, WHO yakaburitsa runyorwa rwakagadziridzwa rwemishonga inouraya zvipembenene uye mishonga inokurudzirwa kupfapfaidza mumba kudzivirira nekudzora zvipembenene zvemalaria, kusanganisira pyrimiphos-methyl. Kune pyrimidinhos methyl, Actellic (Baoan Valley) yave ichishandiswa zvakanyanya munzvimbo dzinosanganisira kurima, kuchengetera zvinhu, hutano hweveruzhinji, uye masango kubvira muna 1970. FAO/WHO Codex Alimentarius Commission yakakurudzira kuti zvasara zvepyrimidinhos-methyl hazvizokonzere njodzi kwenguva refu kuvanhu; International Maritime Organisation inokurudzira kuti pyrimidinhos-methyl inogona kushandiswa muzvikepe; British Brewing Association yakabvumidza pyrimiphos-methyl Inoshandiswa kudzora zvipembenene mukuchengetedza bhari inoshandiswa pakubika; sangano rekudya kwemhuka rakasimbisa kuti ingave tsanga dzakarapwa nepyrimidinhos isati yasvika kana mushure mekukohwa, inogona kupihwa zvakananga kumhuka; chiyero chinokurudzirwa chepyrimidinhos chinoshandiswa kurapa zvigadzirwa zvekurima. Yakashandiswa zvizere uye inogamuchirwa mukutengeserana kwenyika dzakawanda. Baoan Valley yakashandiswa zvinobudirira kuchengetedza nekudzivirira zvigadzirwa zvekurima munyika dzinopfuura makumi manomwe pasi rose. Zviyo zvakachengetwa, tofu yakaomeswa, zvigadzirwa zvemukaka, hove dzakaomeswa, michero yakaomeswa, nezvimwewo zvinoda kudzora zvipembenene nezvipembenene kwenguva pfupi kana kwenguva refu. Baoangu inoonekwa semushonga wezvipembenene wepasi rose uye wakanaka wekuchengetedza zvipembenene.
Mirayiridzo:
(1) Kugadzirisa kugadzirwa kwemudura usina zviyo. Kunyungudutsa 1:50 uye kupfapfaidza kwakaenzana, pfapfaidza 50 mL yemushonga wakasanganiswa pa square mita.
(2) Kugadzira zviyo nemishonga - kusanganisa mudura rese. Kuyera kutanga, sanganisa uchipfapfaidza, uye pakupedzisira woisa mudura. Baoan Valley inosanganiswa ne1:100 uye inopfapfaidzwa netani imwe yezviyo.
(3) Kugadzira tsanga nemishonga - kusanganisa pamusoro. Rutivi rwepamusoro rwakareba 30-100 cm, rwakasanganiswa, rwakapfapfaidzwa, uye rwakasanganiswa.
(4) Kubata zviyo nemishonga - kugadziriswa kwemabhegi ekurongedza. Sanganisa 1:50, woisa saga rimwe chete pa50 mL (masaga acho anoverengerwa se0.5m×1m).
Kubva pamaonero aya, kushandiswa kwe pyrimidinhos methyl panzvimbo pe Aluminium phosphide chinhu chakachengeteka uye chakavimbika, uye mhedzisiro yekushandisa pyrimidinhos methyl yakanaka kwazvo, izvo zvakarumbidzwa nevanhu vose.
