Zomwe tizilombo zimatha pyrethroids kupha

 Mankhwala opha tizilombo a pyrethroid amaphatikizapoCypermetrin, Deltamethrin, cyfluthrin, ndi cypermethrin, ndi zina zotero.

Cypermethrin: Amagwiritsidwa ntchito makamaka poletsa kutafuna ndi kuyamwa tizilombo toyambitsa matenda komanso nthata zosiyanasiyana zamasamba.

Deltamethrin: Imagwiritsidwa ntchito kwambiri pothana ndi tizirombo ta Lepidoptera ndi homoptera, komanso imakhala ndi zotsatira zina pa tizirombo ta Orthoptera, Diptera, hemiptera ndi Coleoptera.

Cyanothrin: Imagwiritsidwa ntchito kwambiri polimbana ndi tizirombo ta lepidoptera, komanso imakhala ndi zotsatira zabwino pa tizirombo ta homoptera, hemiptera ndi diptera.

Zomwe ziyenera kudziwidwa popopera mankhwala ophera tizilombo

1. Mukamagwiritsa ntchitomankhwala ophera tizilombokuti muchepetse tizilombo toononga mbewu, ndikofunikira kusankha mankhwala oyenera ndikuwagwiritsa ntchito panthawi yoyenera. Potengera nyengo komanso momwe tizirombo timachitira tsiku ndi tsiku, mankhwala ophera tizilombo amayenera kugwiritsidwa ntchito nthawi yabwino. Ndikoyenera kugwiritsa ntchito mankhwala ophera tizilombo pakati pa 9 ndi 10 am komanso pambuyo pa 4pm

2. Pambuyo pa 9 koloko, mame pamasamba a mbewu auma, ndipo ndi nthawi yomwe tizilombo toyambitsa matenda timakhala tikugwira ntchito kwambiri. Kugwiritsa ntchito mankhwala ophera tizilombo panthawiyi sikungakhudze mphamvu yolamulira chifukwa cha kusungunuka kwa mankhwala ophera tizilombo ndi mame, komanso sikudzalola kuti tizirombo tigwirizane ndi mankhwala ophera tizilombo, kuonjezera mwayi wakupha tizilombo.

3. Pambuyo pa 4 koloko masana, kuwala kumachepa ndipo ndi nthawi yomwe tizilombo touluka ndi usiku tatsala pang'ono kutuluka. Kupaka mankhwala panthawiyi kungapangitse kuti mankhwalawa ayambe kuikidwa ku mbewu. Tizilombo tikatuluka kuti tiyambe kugwira ntchito kapena kudyetsa madzulo ndi usiku, timakumana ndi utsi kapena kupha poyizoni ndi kufa. Panthawi imodzimodziyo, zingathenso kuteteza kutaya kwa evaporation ndi photodecomposition kulephera kwa mankhwala ophera tizilombo.

4.Mitundu yosiyanasiyana ya mankhwala ophera tizilombo ndi njira zogwiritsidwira ntchito ziyenera kusankhidwa malinga ndi mbali zowonongeka za tizilombo, ndipo mankhwala ayenera kuperekedwa kumalo oyenera. Tizilombo towononga mizu, thirani mankhwala kumizu kapena m'ngalande zofesa. Tizilombo timene timadya pansi pa masamba, tsitsani mankhwala amadzimadzi pansi pa masamba.

 5. Pofuna kuthana ndi mphutsi zofiira ndi thonje, perekani mankhwalawa ku maluwa a maluwa, mabelu obiriwira ndi nsonga zamagulu. Kuteteza 螟虫 ndikuyambitsa mbande zakufa, kuwaza dothi lapoizoni; Kupewa ndi kuwongolera zoyera zoyera, utsi kapena kuthira madzi. Kuti muchepetse zokolola za mpunga ndi masamba ampunga, tsitsani mankhwala amadzimadzi m'munsi mwa mbewu za mpunga. Kuti muchepetse njenjete ya diamondi, thirirani mankhwala amadzimadzi pamaluwa amaluwa ndi mphukira zazing'ono.

 6. Kuonjezera apo, kwa tizirombo zobisika monga nsabwe za m'masamba, akangaude ofiira, ma planthoppers a mpunga, ndi ma leafhoppers a mpunga, pogwiritsa ntchito njira yawo yoyamwa ndi kuboola pakamwa, mankhwala amphamvu ophera tizilombo amatha kusankhidwa. Akayamwa, amatha kufalikira kumadera ena a mmera kuti akwaniritse cholinga chopereka mankhwalawo pamalo oyenera.
