Mafotokozedwe Akatundu:

LufenuronNdi mbadwo waposachedwa kwambiri wosintha mankhwala ophera tizilombo a urea. Mankhwalawa amapha tizilombo pochita zinthu ndi mphutsi za tizilombo ndikuletsa kuchotsedwa kwa mphutsi, makamaka mbozi zomwe zimadya masamba monga mitengo ya zipatso, ndipo ali ndi njira yapadera yophera tizilombo ta thrips, dzimbiri ndi ntchentche zoyera. Mankhwala ophera tizilombo a Ester ndi organophosphorus amatulutsa tizilombo tolimba.

Mawonekedwe:

Mphamvu yokhalitsa ya mankhwalayi imathandiza kuchepetsa kupopera mankhwala pafupipafupi; kuti mbewu zisawonongeke, chimanga, ndiwo zamasamba, zipatso za citrus, thonje, mbatata, mphesa, soya ndi mbewu zina zitha kugwiritsidwa ntchito, ndipo ndi yoyenera kuwongolera tizilombo towononga. Mankhwalawa sadzayambitsanso tizilombo toyamwa toyamwa, ndipo amakhudza tizilombo tothandiza komanso akangaude odya nyama zazikulu. Amatha kupirira mvula komanso amasankha tizilombo tothandiza tomwe timadya nyama zazikulu. Pambuyo poika, zotsatira zake zimakhala pang'onopang'ono koyamba, ndipo amagwira ntchito yopha mazira, omwe amatha kupha mazira omwe angoyikidwa kumene. Ali ndi poizoni wochepa kwa njuchi ndi njuchi, ali ndi poizoni wochepa kwa tizilombo toyamwitsa, ndipo angagwiritsidwe ntchito ndi njuchi akamasonkhanitsa uchi. Ndi otetezeka kuposa mankhwala ophera tizilombo a organophosphorus ndi carbamate, angagwiritsidwe ntchito ngati mankhwala abwino ophatikizana, ndipo amawongolera bwino tizilombo ta lepidopteran. Akagwiritsidwa ntchito pamlingo wochepa, amakhala ndi mphamvu yowongolera bwino pa mphutsi ndi mphutsi za thrips; Zingathe kuletsa kufalikira kwa mavairasi, ndipo zimatha kulamulira bwino tizilombo ta lepidopteran tomwe sitingathe kupirira matenda a pyrethroids ndi organophosphorus. Mankhwalawa ndi osankha komanso okhalitsa, ndipo ali ndi mphamvu yabwino yolamulira tizilombo tomwe timamera m'nthaka kumapeto. Kuwonjezera pa kuchepetsa kuchuluka kwa kupopera, zimatha kuwonjezera kwambiri kupanga.

Malangizo：
Pa zinthu zopukutira masamba, zopukutira masamba, nthata za dzimbiri za apulo, nthata za codling, ndi zina zotero, magalamu 5 a zosakaniza zogwira ntchito angagwiritsidwe ntchito kupopera makilogalamu 100 a madzi. Pa nthata za phwetekere armyworm, beet armyworm, flower thrips, phwetekere, thonje la bollworm, mbatata stem borer, tomato rust mite, eggplant fruit borer, diamondback moth, ndi zina zotero, magalamu 100 a madzi akhoza kupopera magalamu 3 mpaka 4 a zosakaniza zogwira ntchito. Mukamagwiritsa ntchito, ndikofunikira kusamala kuti mugwiritse ntchito mosinthana ndi mankhwala ena ophera tizilombo monga kuron, vermectin, ndi abamectin.
