Musi wa7 Gunyana, 2023, Hofisi Yepamusoro yeBazi rezveKurima neMatunhu ekuMaruwa yakaburitsa tsamba ichikumbira maonero pamusoro pekushandiswa kwematanho akarambidzwa ekutarisira mishonga mina ine chepfu ine chepfu, kusanganisira omethoate. Pfungwa idzi dzinoti kutanga musi wa1 Zvita, 2023, dare rinopa mishonga richabvisa kunyoreswa kwemishonga yeomethoate, carbofuran, methomyl, uye aldicarb, kurambidza kugadzirwa, uye izvo zvakagadzirwa zviri pamutemo zvinogona kutengeswa nekushandiswa mukati menguva yekuvimbisa mhando. Kutanga musi wa1 Zvita, 2025, kutengeswa nekushandiswa kwezvigadzirwa zvataurwa pamusoro apa zvinorambidzwa; Chete chengetedza kugadzirwa kwezvinhu zvisina kucheneswa uye kutengeswa kunze kwenyika kwemakambani ekugadzira zvinhu zvisina kucheneswa, uye shandisa kuchengetedzwa kwekushanda kwakavharwa. Kuburitswa kwepfungwa iyi kunogona kuratidza kubuda kweKPMG, iyo yave yakanyorwa muChina kweanopfuura makore makumi mashanu kubva kuma1970, kubva kumusika wekurima weChina.
Carbofuran mushonga wezvipembenene wecarbamate wakagadzirwa pamwe chete neFMC neBayer, unoshandiswa kuuraya zvikwekwe, zvipembenene, uye nematodes. Une simba rekuuraya mazai mukati, kuuraya zvipembenene, uye chepfu mudumbu, uye une simba rekuuraya mazai. Unogara kwenguva refu uye kazhinji une hafu yehupenyu hwemazuva 30-60 muvhu. Kare waishandiswa muminda yemupunga kudzora zvikwekwe zvemupunga, zvikwekwe zvemupunga, zvikwekwe zvemupunga, zvikwekwe zvemupunga, uye midges yemupunga; Kudzivirira nekudzivirira maaphid edonje, zvikwekwe zvedonje, zvikwekwe zvemupunga, uye zvikwekwe zvemupunga muminda yedonje. Parizvino, unonyanya kushandiswa muminda isiri yezvirimwa senge miti yegreening nebindu kudzivirira nekudzivirira matiger emumunda, maaphid, ma longicorn beetle, ma mealworms, nhunzi dzemichero, zvikwekwe zvine mapapiro zvinopenya, nyuchi dzinonzi stem, uye zvipembenene zvevhu remidzi.
Carbofuran mushonga unodzivirira acetylcholinesterase, asi kusiyana nemimwe mishonga yekuuraya zvipembenene inonzi carbamate, kubatana kwayo necholinesterase hakuchinjiki, zvichikonzera chepfu yakanyanya. Carbofuran inogona kutorwa nemidzi yemiti yoendeswa kunhengo dzakasiyana dzemuti. Inoungana yakawanda mumashizha, kunyanya pamucheto wemashizha, uye ine huwandu hushoma mumuchero. Kana zvipembenene zvikatsenga nekuyamwa muto wemashizha emiti ine chepfu kana kuruma matishu ane chepfu, acetylcholinesterase mumuviri wemuti inodziviswa, zvichikonzera chepfu yeuropi nerufu. Hupenyu hwehafu muvhu hunosvika mazuva makumi matatu kusvika makumi matanhatu. Kunyangwe ichishandiswa kwemakore mazhinji, kuchine mishumo yekuti mushonga uyu haupindirwe necarbofuran.
Carbofuran mushonga wezvipembenene une hunyanzvi hwakasiyana-siyana, unoshanda zvakanaka, uye une zvipembenene zvishoma unoshandiswa zvakanyanya mumunda wekurima. Zvisinei, mumakore achangopfuura, carbofuran yakabviswa zvishoma nezvishoma uye inenge yava kuda kubuda zvachose mumusika weChina panosvika kupera kwa2025. Shanduko iyi yakakosha ichava nemhedzisiro yakati pakurima kweChina. Zvisinei, nekufamba kwenguva, iyi inogona kunge iri nhanho inodiwa pakukura kwekurima kwenguva refu uye nzira isingadzivisike yekukura kwekurima kusingakuvadzi zvakatipoteredza.
