Kugwiritsa ntchito mankhwala ophera tizilombo kuti muteteze ndi kuwononga matenda, tizirombo, udzu ndi makoswe ndi njira yofunika kwambiri kuti muthe kukolola zambiri zaulimi.Ngati atagwiritsidwa ntchito molakwika, amathanso kuwononga chilengedwe ndi zinthu zaulimi ndi ziweto, kubweretsa poyizoni kapena kufa kwa anthu ndi ziweto.
Gulu la mankhwala ophera tizilombo:
Malinga ndi kuwunika kwathunthu kwa kawopsedwe (kawopsedwe wapakamwa kwambiri, kawopsedwe wapakamwa, kawopsedwe wapakhungu, kawopsedwe kosatha, etc.) wa mankhwala omwe amagwiritsidwa ntchito kwambiri (zopangira) popanga ulimi, amagawidwa m'magulu atatu: kawopsedwe wamkulu, kawopsedwe wapakatikati, ndi kawopsedwe kakang'ono.
1. Mankhwala oopsa kwambiri akuphatikizira 3911, Suhua 203, 1605, Methyl 1605, 1059, Fenfencarb, Monocrofos, Phosphamide, Methamidophos, Isopropaphos, Trithion, omethoate, 401, etc.
2. Mankhwala ophera tizilombo oopsa kwambiri ndi monga fenitrothion, dimethoate, Daofengsan, ethion, imidophos, picophos, hexachlorocyclohexane, homopropyl hexachlorocyclohexane, toxaphene, chlordane, DDT, ndi chloramphenicol, ndi zina zotero.
3. Mankhwala ophera tizilombo toyambitsa matenda akuphatikizapo trichlorfon, marathon, acephate, phoxim, diclofenac, carbendazim, tobuzin, chloramphenicol, diazepam, chlorpyrifos, chlorpyrifos, glyphosate, etc.
Mankhwala ophera tizilombo oopsa kwambiri amatha kupha poyizoni kapena kufa ngati apezeka ndi ochepa kwambiri.Ngakhale kawopsedwe wa mankhwala ophera tizilombo apakati komanso otsika ndi ochepa, kuwonetseredwa pafupipafupi komanso kupulumutsidwa mosayembekezereka kungayambitsenso imfa.Choncho, m'pofunika kulabadira chitetezo pamene ntchito mankhwala.
Kuchuluka kwa Kagwiritsidwe:
Mitundu yonse yomwe yakhazikitsa "miyezo yogwiritsira ntchito mankhwala ophera tizilombo" iyenera kutsatira zofunikira za "miyezo".Kwa mitundu yomwe sinakhazikitsebe "miyezo", zotsatirazi ziyenera kutsatiridwa:
1. Mankhwala oopsa kwambiri saloledwa kugwiritsidwa ntchito mu mbewu monga masamba, tiyi, mitengo yazipatso, ndi mankhwala azikhalidwe achi China, ndipo saloledwa kugwiritsidwa ntchito popewa komanso kuletsa tizirombo toyambitsa matenda komanso matenda a khungu la anthu ndi nyama.Kupatula mankhwala a rodenticides, saloledwa kugwiritsidwa ntchito pa makoswe oopsa.
2. Mankhwala ophera tizilombo otsalira kwambiri monga hexachlorocyclohexane, DDT, ndi chlordane saloledwa kugwiritsidwa ntchito pa mbewu monga mitengo ya zipatso, masamba, mitengo ya tiyi, mankhwala achi China, fodya, khofi, tsabola, ndi citronella.Chlordane amaloledwa kuthira njere ndikuwongolera tizirombo tapansi panthaka.
3. Chloramid atha kugwiritsidwa ntchito polimbana ndi kangaude wa thonje, mpunga, ndi tizirombo tina.Malinga ndi zotsatira za kafukufuku pa kawopsedwe ka chlorpyrifos, kugwiritsidwa ntchito kwake kuyenera kuwongoleredwa.Pa nthawi yonse ya kukula kwa mpunga, amaloledwa kugwiritsidwa ntchito kamodzi kokha. Gwiritsani ntchito 2 taels ya 25% madzi pa ekala, ndi osachepera masiku 40 kuchokera nthawi yokolola.Gwiritsani ntchito madzi 4 a 25% pa ekala, ndi masiku osachepera 70 kuchokera nthawi yokolola.
4. Ndikoletsedwa kugwiritsa ntchito mankhwala ophera tizilombo kukupha nsomba, shrimp, achule, mbalame ndi zinyama zopindulitsa.
