Mu nyengo ino ya chaka chilichonse, tizilombo tochuluka timabuka (army bug, Spodoptera littoralis, Spodoptera litura, Spodoptera frugiperda, ndi zina zotero), zomwe zimawononga kwambiri mbewu. Monga mankhwala ophera tizilombo ambiri, chlorfenapyr ili ndi mphamvu yabwino yolamulira tizilomboti.
1. Makhalidwe a chlorfenapyr
(1) Chlorfenapyr ili ndi mitundu yosiyanasiyana ya mankhwala ophera tizilombo komanso ntchito zake zosiyanasiyana. Ingagwiritsidwe ntchito polimbana ndi mitundu yambiri ya tizilombo monga Lepidoptera ndi Homoptera pa ndiwo zamasamba, mitengo ya zipatso, ndi mbewu zakumunda, monga diamondback moth, cabbage worm, beet armyworm, ndi twill. Tizilombo tambirimbiri tomwe timadya masamba monga noctuid moth, cabbage borer, cabbage aphid, leafminer, thrips, ndi zina zotero, makamaka motsutsana ndi akuluakulu a tizilombo ta Lepidoptera, ndi othandiza kwambiri.
(2) Chlorfenapyr imapha tizilombo m'mimba ndipo imapha tizilombo tomwe timakhudza. Imalowa bwino kwambiri pamwamba pa tsamba, imakhala ndi mphamvu zinazake, ndipo imakhala ndi mphamvu zambiri zophera tizilombo, imalamulira bwino, imakhala ndi mphamvu zokhalitsa komanso chitetezo. Kuthamanga kwa tizilombo kumathamanga, imalowa bwino, ndipo mankhwala ophera tizilombo ndi okwanira. (Tizilombo tingaphedwe mkati mwa ola limodzi mutatha kupopera, ndipo mphamvu yolamulira ya tsikulo imatha kufika pa 85%).
(3) Chlorfenapyr imateteza kwambiri tizilombo tosalimba, makamaka tizilombo tosalimba tomwe sitingathe kupirira mankhwala ophera tizilombo monga organophosphorus, carbamate, ndi pyrethroids.
2. Kusakaniza kwa chlorfenapyr
Ngakhale kuti chlorfenapyr ili ndi mitundu yosiyanasiyana ya mankhwala ophera tizilombo, zotsatira zake zimakhala zabwino, ndipo kukana kwa mankhwala ndi kochepa. Komabe, mankhwala aliwonse, ngati atagwiritsidwa ntchito okha kwa nthawi yayitali, adzakhala ndi mavuto okana mankhwala mtsogolo.
Chifukwa chake, popopera mankhwala enieni, chlorfenapyr nthawi zambiri iyenera kusakanikirana ndi mankhwala ena kuti ichepetse kupanga mankhwala osagwira ntchito komanso kupititsa patsogolo mphamvu yolamulira.
(1) Kuphatikiza kwachlorfenapyr + emamectin
Pambuyo pophatikiza chlorfenapyr ndi emamectin, imakhala ndi mitundu yosiyanasiyana ya mankhwala ophera tizilombo, ndipo imatha kuletsa tizilombo toyambitsa matenda monga thrips, stink bug, flea beetles, red spiders, heartworms, corn borers, kabichi mbozi ndi tizilombo tina towononga ndiwo zamasamba, minda, mitengo ya zipatso ndi mbewu zina.
Komanso, mutasakaniza chlorfenapyr ndi emamectin, nthawi yokhalitsa ya mankhwalawa imakhala yayitali, zomwe zimathandiza kuchepetsa kuchuluka kwa nthawi yogwiritsira ntchito mankhwalawa ndikuchepetsa mtengo wogwiritsira ntchito wa alimi.
Nthawi yabwino kwambiri yogwiritsira ntchito: mu gawo la 1-3 la tizilombo, pamene kuwonongeka kwa tizilombo m'munda kuli pafupifupi 3%, ndipo kutentha kumayendetsedwa pa madigiri pafupifupi 20-30, zotsatira zake zimakhala zabwino kwambiri.
(2) chlorfenapyr +indoxacarb yosakanizidwa ndi indoxacarb
Pambuyo posakaniza chlorfenapyr ndi indoxacarb, sizingopha tizilombo mwachangu (tizilombo timasiya kudya nthawi yomweyo titakhudza mankhwala ophera tizilombo, ndipo tizilombo timafa mkati mwa masiku 3-4), komanso zimasunga mphamvu zake kwa nthawi yayitali, zomwe ndizoyeneranso mbewu. Chitetezo.
Kusakaniza kwa chlorfenapyr ndi indoxacarb kungagwiritsidwe ntchito polimbana ndi tizilombo ta lepidopteran, monga thonje la thonje, mbozi ya kabichi ya m'minda ya cruciferous, diamondback moth, beet armyworm, ndi zina zotero, makamaka kukana kwa noctuid moth n'kodabwitsa.
Komabe, zinthu ziwirizi zikasakanizidwa, zotsatira zake pa mazira sizili bwino. Ngati mukufuna kupha mazira onse awiri ndi akuluakulu, mutha kugwiritsa ntchito lufenuron pamodzi.
Nthawi yabwino kwambiri yogwiritsira ntchito: pakati ndi kumapeto kwa kukula kwa mbewu, pamene tizilombo takalamba, kapena pamene mibadwo yachiwiri, itatu, ndi inayi ya tizilombo tasakanikirana, zotsatira za mankhwala zimakhala zabwino.
(3)chlorfenapyr + abamectin mankhwala
Abamectin ndi chlorfenapyr zimaphatikizidwa ndi mphamvu yodziwikiratu yogwirizana, ndipo zimagwira ntchito motsutsana ndi tizilombo toyambitsa matenda tosalimba, mbozi, beet armyworm, ndi leek. Zonsezi zimakhala ndi mphamvu zabwino zowongolera.
Nthawi yabwino yogwiritsira ntchito: pakati ndi kumapeto kwa kukula kwa mbewu, pamene kutentha kuli kochepa masana, zotsatira zake zimakhala zabwino. (Pamene kutentha kuli kotsika kuposa madigiri 22, mphamvu ya abamectin yopha tizilombo imakhala yokwera).
(4) Kugwiritsa ntchito chlorfenapyr mosakaniza ndi zinamankhwala ophera tizilombo
Kuphatikiza apo, chlorfenapyr ingasakanizidwenso ndi thiamethoxam, bifenthrin, tebufenozide, ndi zina zotero kuti iwononge tizilombo toyambitsa matenda monga thrips, diamondback moths ndi tizilombo tina.
Poyerekeza ndi mankhwala ena: chlorfenapyr imagwiritsidwa ntchito kwambiri polimbana ndi tizilombo ta lepidopteran, koma kuwonjezera pa chlorfenapyr, palinso mankhwala ena awiri omwe ali ndi zotsatira zabwino zowongolera tizilombo ta lepidopteran, omwe ndi lufenuron ndi indene Wei.
Ndiye, kodi kusiyana kwa mankhwala atatuwa ndi kotani? Kodi tiyenera kusankha bwanji mankhwala oyenera?
Othandizira atatuwa ali ndi ubwino ndi kuipa kwawo. Mu ntchito zenizeni, titha kusankha wothandizira woyenera malinga ndi momwe zinthu zilili.
