Kuiswa kwemishonga yekudzivirira nekudzivirira zvirwere, zvipembenene, sora nemakonzo idanho rakakosha kuti vawane goho guru rekurima.Kana ikashandiswa zvisina kunaka, inogona zvakare kusvibisa nharaunda uye zvigadzirwa zvekurima nezvipfuyo, zvichikonzera muchetura kana kufa kuvanhu nezvipfuyo.
Kurongwa kwemishonga yezvipembenene:
Zvinoenderana nehuwandu hwehupfu hwekuongorora (acute oral toxicity, dermal toxicity, chronic toxicity, etc.) yezvinowanzo shandiswa mishonga yezvipembenene (raw materials) mukugadzirwa kwekurima, yakakamurwa kuita zvikamu zvitatu: high toxicity, medium toxicity, uye low toxicity.
1. Mishonga ine chepfu yepamusoro inosanganisira 3911, Suhua 203, 1605, Methyl 1605, 1059, Fenfencarb, Monocrofos, Phosphamide, Methamidophos, Isopropaphos, Trithion, omethoate, 401, nezvimwewo.
2. Mishonga ine chepfu ine mwero inosanganisira fenitrothion, dimethoate, Daofengsan, ethion, imidophos, picophos, hexachlorocyclohexane, homopropyl hexachlorocyclohexane, toxaphene, chlordane, DDT, uye chloramphenicol, nezvimwewo.
3. Low toxicity pesticides inosanganisira trichlorfon, marathon, acephate, phoxim, diclofenac, carbendazim, tobuzin, chloramphenicol, diazepam, chlorpyrifos, chlorpyrifos, glyphosate, nezvimwewo.
Mishonga inouraya zvipembenene ine muchetura inogona kukonzera chepfu kana kufa kana ikaiswa zvishoma.Kunyangwe huturu hwemishonga yezvipembenene yepakati uye yakaderera iri shoma, kugara uchiratidzwa uye kununurwa nekukasira kunogona kukonzera rufu.Nokudaro, zvakakosha kubhadhara kune kuchengeteka paunenge uchishandisa mishonga yezvipembenene.
Kuwanda Kwekushandisa:
Mhando dzese dzakagadzira "mashandisiro ekuchengetedza mishonga yezvipembenene" dzinoenderana nezvinodiwa ne "zviyero".Kune mhando dzisati dzatanga "zviyero", zvinotevera zvinongedzo zvichaitwa:
1. Mishonga ine chepfu yakakwira haibvumidzwe kushandiswa muzvirimwa zvakaita semuriwo, tii, miti yemichero, nemishonga yechivanhu yekuChina, uye haibvumidzwe kushandiswa kudzivirira nekudzora zvipembenene zveutano uye zvirwere zveganda revanhu nemhuka.Kunze kwema rodenticides, haatenderwe kushandiswa kune huturu hwemakonzo.
2. Mishonga yezvipembenene yakasara yakadai sehexachlorocyclohexane, DDT, uye chlordane haibvumidzwe kushandiswa pazvirimwa zvakaita semiti yemichero, miriwo, miti yetii, mishonga yechivanhu yekuChina, fodya, kofi, mhiripiri, uye citronella.Chlordane inobvumirwa chete kupfekedza mbeu uye kutonga kwezvipembenene zvepasi pevhu.
3. Chloramid inogona kushandiswa kudzora dandemutande redonje, mupunga, nezvimwe zvipembenene.Zvinoenderana nemhedzisiro yekutsvagisa pamusoro pehupfu hwechlorpyrifos, kushandiswa kwayo kunofanirwa kudzorwa.Munguva yose yekukura kwemupunga, inongobvumirwa kushandiswa kamwe chete.Shandisa 2 taels ye 25% mvura paeka, nemazuva mashoma makumi mana kubva panguva yekukohwa.Shandisai 4 taels ye 25% yemvura paeka, nemazuva mashoma makumi manomwe kubva panguva yekukohwa.
4. Zvinorambidzwa kushandisa mishonga inouraya zvipembenene muchetura hove, shrimp, matatya, uye shiri nemhuka zvinobatsira.
