Mawu Oyamba

Lambda-cyhalothrin ili ndi mawonekedwe ambiri ophera tizilombo, ntchito yayikulu komanso kuchita bwino mwachangu.Imalimbana ndi kukokoloka kwa mvula mutatha kupopera mbewu mankhwalawa, koma ndikosavuta kukana pambuyo poigwiritsa ntchito kwa nthawi yayitali.Iwo ali ena ulamuliro kwambiri tizirombo ndi nthata za minga kuyamwa pakamwa mbali, koma mlingo wa nthata ndi 1-2 zina kuposa ochiritsira mlingo.
Ndi yoyenera ku tizirombo ta mtedza, soya, thonje, mitengo ya zipatso ndi ndiwo zamasamba.
Mafomu amtundu wamba akuphatikizapo 2.5% EC, 5% EC, 10% WP, 15% WP, ndi zina zotero.

Kugwiritsa ntchito

2.1 Kupha tizirombo totani?
Mankhwala ophera tizirombo a pyrethroid ndi ma acaricides okhala ndi mphamvu zambiri, mawonekedwe otakata komanso mwachangu amakhudza kwambiri kawopsedwe am'mimba, popanda kuyamwa mkati.
Zimakhala ndi zotsatira zabwino pa Lepidoptera, Coleoptera, Hemiptera ndi tizirombo tina, komanso nthata zamasamba, nthata za dzimbiri, nthata za ndulu, nthata za tarsomedial, etc. pamene tizilombo ndi nthata zimagwirizana, zimatha kulamulira thonje, bollworm, Pieris rapae, masamba constrictor aphid, tiyi inchworm, mbozi tiyi, tiyi orange gall mite, leaf ndulu mite, citrus leaf moth, orange aphid, citrus leaf mite, dzimbiri mite Pichesi zipatso zoboola ndi mapeyala borer angagwiritsidwenso ntchito kulamulira zosiyanasiyana pamwamba ndi tizirombo taumoyo wa anthu.Pofuna kupewa ndi kuwongolera mbozi za thonje ndi mbozi za thonje, mazira a m'badwo wachiwiri, wachitatu adapoperapo ndi 2.5% nthawi 1000 ~ 2000 nthawi yamafuta njira yochizira kangaude wofiira, bridging bug ndi thonje bug.The ulamuliro kabichi mbozi ndi masamba nsabwe za m'masamba anali utsi pa 6 ~ 10mg/L ndi 6.25 ~ 12.5mg/L ndende motero.Kuwongolera kwa mgodi wa masamba a citrus ndi kutsitsi kwa 4.2 ~ 6.2mg/L ndende.
2.2 Zogwiritsidwa ntchito pa mbewu ziti?
Amagwiritsidwa ntchito ngati tirigu, chimanga, mitengo yazipatso, thonje, masamba a cruciferous, etc.
2.3 Mlingo ndi kagwiritsidwe ntchito

Mbali ndi zotsatira

Cyhalothrin ili ndi mawonekedwe amphamvu, imalepheretsa kuyendetsa ma axon a mitsempha ya tizilombo, ndipo imakhala ndi zotsatira zopewera, kugwetsa pansi ndi kupha tizilombo.Lili ndi mankhwala ambiri ophera tizirombo, limagwira ntchito kwambiri komanso limagwira ntchito mwachangu.Imalimbana ndi kukokoloka kwa mvula mutatha kupopera mbewu mankhwalawa, koma ndikosavuta kukana pambuyo poigwiritsa ntchito kwa nthawi yayitali.Iwo ali ena ulamuliro kwambiri tizilombo tizirombo ndi nthata za minga kuyamwa mouthparts, ndi kanthu limagwirira ndi chimodzimodzi Fenvalerate ndi fenpropathrin.Kusiyana kwake ndikuti kumakhala ndi zoletsa zabwino pa nthata.Ikagwiritsidwa ntchito koyambirira kwa mite, imatha kulepheretsa kuchuluka kwa mite.Pamene nthata zachitika zochulukirapo, chiwerengero chake sichikhoza kulamulidwa.Choncho, angagwiritsidwe ntchito pochiza tizilombo ndi nthata, osati mankhwala apadera a acaricide.
