Kugwiritsa ntchito mankhwala ophera tizilombo popewa ndi kuletsa matenda, tizilombo toononga, udzu, ndi makoswe ndi njira yofunika kwambiri kuti tipeze zokolola zambiri m'minda. Ngati sizigwiritsidwa ntchito molakwika, zimatha kuipitsanso chilengedwe ndi zinthu zaulimi ndi ziweto, zomwe zimayambitsa poizoni kapena imfa kwa anthu ndi ziweto.
Kugawa mankhwala ophera tizilombo：
Malinga ndi kuwunika kwathunthu kwa poizoni (kuopsa kwa pakamwa, kuopsa kwa khungu, kuopsa kwa nthawi yayitali, ndi zina zotero) kwa mankhwala ophera tizilombo omwe amagwiritsidwa ntchito kwambiri (zipangizo zopangira) pa ulimi, amagawidwa m'magulu atatu: kuopsa kwambiri, kuopsa kwapakati, ndi kuopsa kochepa.
1. Mankhwala ophera tizilombo oopsa kwambiri ndi awa: 3911, Suhua 203, 1605, Methyl 1605, 1059, Fenfencab, Monocrofos, Phosphamide, Methamidophos, Isopropaphos, Trithion, omethoate, 401, ndi zina zotero.
2. Mankhwala ophera tizilombo omwe ali ndi poizoni pang'ono ndi monga fenitrothion, dimethoate, Daofengsan, ethion, imidophos, picophos, hexachlorocyclohexane, homopropyl hexachlorocyclohexane, toxaphene, chlordane, DDT, ndi chloramphenicol, ndi zina zotero.
3. Mankhwala ophera tizilombo omwe ali ndi poizoni wochepa ndi monga trichlorfon, marathon, acephate, phoxim, diclofenac, carbendazim, tobuzin, chloramphenicol, diazepam, chlorpyrifos, chlorpyrifos, glyphosate, ndi zina zotero.
Mankhwala ophera tizilombo oopsa kwambiri angayambitse poizoni kapena imfa ngati atagwiritsidwa ntchito pang'ono kwambiri. Ngakhale kuti poizoni wa mankhwala ophera tizilombo ophera tizilombo ophera tizilombo ndi ochepa ndi wochepa, kugwiritsidwa ntchito pafupipafupi komanso kupulumutsidwa msanga kungayambitsenso imfa. Chifukwa chake, ndikofunikira kusamala za chitetezo mukamagwiritsa ntchito mankhwala ophera tizilombo.
Kukula kwa Kagwiritsidwe Ntchito:
Mitundu yonse yomwe yakhazikitsa "miyezo yogwiritsira ntchito mankhwala ophera tizilombo" iyenera kutsatira zofunikira za "miyezo". Kwa mitundu yomwe sinakhazikitse "miyezo", malamulo otsatirawa ayenera kutsatiridwa:
1. Mankhwala ophera tizilombo oopsa kwambiri saloledwa kugwiritsidwa ntchito m'zomera monga ndiwo zamasamba, tiyi, mitengo ya zipatso, ndi mankhwala achikhalidwe aku China, ndipo saloledwa kugwiritsidwa ntchito popewa ndi kuwongolera tizilombo toyambitsa matenda komanso matenda a pakhungu la anthu ndi nyama. Kupatula mankhwala ophera tizilombo toyambitsa matenda, saloledwa kugwiritsidwa ntchito pa makoswe oopsa.
2. Mankhwala ophera tizilombo monga hexachlorocyclohexane, DDT, ndi chlordane saloledwa kugwiritsidwa ntchito pa mbewu monga mitengo ya zipatso, ndiwo zamasamba, mitengo ya tiyi, mankhwala achikhalidwe achi China, fodya, khofi, tsabola, ndi citronella. Chlordane amaloledwa kokha pobzala mbewu ndi kuwongolera tizilombo tomwe timakhala pansi pa nthaka.
3. Chloramid ingagwiritsidwe ntchito polimbana ndi kangaude wa thonje, borer wa mpunga, ndi tizilombo tina. Malinga ndi zotsatira za kafukufuku wokhudza poizoni wa chlorpyrifos, kugwiritsidwa ntchito kwake kuyenera kulamulidwa. Pa nthawi yonse yokolola mpunga, umaloledwa kugwiritsidwa ntchito kamodzi kokha. Gwiritsani ntchito ma taels awiri a madzi 25% pa ekala, ndi masiku osachepera 40 kuchokera nthawi yokolola. Gwiritsani ntchito ma taels anayi a madzi 25% pa ekala, ndi masiku osachepera 70 kuchokera nthawi yokolola.
4. N'koletsedwa kugwiritsa ntchito mankhwala ophera tizilombo kuti tiphe nsomba, nkhanu, achule, ndi mbalame ndi nyama zothandiza.
