Asystemic tizilombondi mankhwala omwe amatengedwa ndi mbewu ndikuyendetsa thupi lonse la mbewuyo. Mosiyana ndi mankhwala ophera tizilombo omwe si a systemic, mankhwala ophera tizilombo samangokhala pamwamba pa utsi, koma amatengedwa kudzera mumizu, tsinde, ndi masamba a mmera, motero amapanga chotchinga chotchinga pachomera chonsecho.
Momwe Ma Insecticides Amagwirira Ntchito
Mankhwala ophera tizilombo amatengedwa kudzera mumizu ya mbewuyo ndipo kenako amatengedwa kudzera m'mitsempha ya mmera kupita ku mbali zonse za mbewuyo. Tizilombo timene timadya minyewa ya zomera yokhala ndi mankhwala ophera tizirombo timatenthedwa msanga ndipo timafa. Katunduyu wamankhwala ophera tizirombo amawapangitsa kukhala othandiza polimbana ndi tizirombo tobisika mkati mwa mbewu kapena zovuta kufika pamwamba pa mbewu.
Kuyamba kwa zochita za systemic tizilombo
Kuyambika kwa zochita za mankhwala ophera tizilombo kumadalira zinthu zingapo, kuphatikizapo mtundu wa zomera, chilengedwe, ndi mapangidwe a mankhwala. Nthawi zambiri, mankhwala ophera tizilombo amayamba kugwira ntchito pakangotha maola ochepa mpaka masiku angapo atagwiritsidwa ntchito, ndipo tizilombo timafa msanga tikamwedwa.
Kulimbikira nthawi ya systemic tizirombo
Kutalika kwa mphamvu ya mankhwala ophera tizilombo muzomera kumakhudzidwanso ndi zinthu zingapo. Kawirikawiri, zotsatira za mankhwala ophera tizilombo zimatha kuchokera kwa milungu ingapo mpaka miyezi ingapo, zomwe zikutanthauza kuti chomeracho chikhoza kupitiriza kulimbana ndi tizilombo toyambitsa matenda panthawiyi, kuchepetsa kufunika kopopera mankhwala mobwerezabwereza.
Momwe mungagwiritsire ntchito mankhwala ophera tizilombo
Mankhwala ophera tizilombo amagwiritsidwa ntchito m'njira zosiyanasiyana, kuphatikiza kugwiritsa ntchito dothi, kupopera masamba ndi jakisoni wa thunthu. M'munsimu muli njira zingapo zogwiritsiridwa ntchito:
Kuthira dothi: yankho la mankhwala ophera tizirombo limatsanuliridwa m'nthaka mozungulira mizu ya mmera, ndipo mbewuyo imamwa mankhwalawo kudzera mumizu yake.
Kupopera mbewu mankhwalawa: Mankhwala ophera tizirombo amawapopera pamasamba ndipo mankhwalawo amayamwa m'masamba.
Jakisoni wa thunthu: Mankhwala ophera tizirombo amabayidwa mwachindunji mu tsinde la mtengo kuti agwire mwachangu mbewu yonse.
Malangizo Abwino Othira Tizilombo
Pokhala ndi mankhwala ophera tizilombo osiyanasiyana omwe amapezeka pamsika, ndikofunikira kusankha mankhwala abwino kwambiri pazomwe mukufuna. Nawa mankhwala ophera tizilombo othandiza kwambiri:
Imidacloprid: mankhwala ophera tizilombo omwe ndi oyenera kubzala mbewu zosiyanasiyana ndipo amatha kuthana ndi nsabwe za m'masamba, whiteflies ndi tizirombo tina.
Acetamiprid: mankhwala amphamvu ophera nsabwe za m'masamba, whiteflies, etc. Ndi oyenera zipatso, masamba ndi zomera zokongola.
Thiamethoxam: Kawopsedwe wachangu komanso wochepa, wogwiritsidwa ntchito ku mbewu zosiyanasiyana, amatha kuteteza mbewu ku tizirombo kwa nthawi yayitali.
Kugwiritsa ntchito mankhwala ophera tizilombo pamasamba
Ngakhale kuti mankhwala ophera tizilombo amagwiritsidwa ntchito kwambiri pa mbewu, ayenera kugwiritsidwa ntchito mosamala kwambiri pazamasamba. Chifukwa mankhwala ophera tizilombo amatengedwa ndi mbewu, nthawi yotetezedwa iyenera kuloledwa isanakololedwe kuti zokololazo zikhale zotetezeka.
Zotsatira za zokhudza zonse mankhwala ophera njuchi
Tizilombo toyambitsa matenda titha kukhala owopsa ku tizilombo toyambitsa matenda monga njuchi. Kuteteza njuchi, Ndi bwino kupewa ntchito zokhudza zonse tizilombo pa nthawi ya maluwa ndi kusankha mankhwala ena ophera ndi otsika kapena palibe kawopsedwe njuchi.
Kodi zokhudza zonse tizilombo kupha akangaude
Mankhwala ena ophera tizilombo ndi othandiza polimbana ndi akangaude, koma sizinthu zonse zomwe zimakhala ndi izi. Ngati kuli kofunikira, tidzalangiza mankhwala ophera tizilombo aulere omwe angathetsere akangaude.
Mankhwala ophera tizirombo omwe si a systemic ndi otetezeka
Mankhwala ophera tizirombo osagwiritsa ntchito mwadongosolo amagwira ntchito pamalo opoperapo ndipo nthawi zambiri amawonongeka mwachangu m'malo, kotero amatha kukhala otetezeka kuposa mankhwala ophera tizilombo nthawi zina. Komabe, mankhwala ophera tizilombo omwe si a systemic amafunika kugwiritsidwa ntchito pafupipafupi ndipo ndi ovuta kugwiritsa ntchito pothana ndi tizirombo tomwe timabisala mkati mwa mbewu.
