M'nyengo ino ya chaka chilichonse, tizilombo tochuluka timayamba (gulu lankhondo, Spodoptera littoralis, Spodoptera litura, Spodoptera frugiperda, etc.), zomwe zimawononga kwambiri mbewu. Monga mankhwala ophera tizirombo otakata, chlorfenapyr imathandiza bwino tizirombozi.
1. Makhalidwe a chlorfenapyr
(1) Chlorfenapyr ili ndi mankhwala ambiri ophera tizilombo komanso ntchito zosiyanasiyana. Itha kugwiritsidwa ntchito pothana ndi tizirombo tambiri monga Lepidoptera ndi Homoptera pamasamba, mitengo yazipatso, ndi mbewu zakumunda, monga njenjete za diamondback, nyongolotsi ya kabichi, beet armyworm, ndi twill. Tizilombo ta masamba ambiri monga noctuid moth, kabichi borer, kabichi aphid, leafminer, thrips, etc., makamaka kwa akuluakulu a tizirombo ta Lepidoptera, ndi othandiza kwambiri.
(2) Chlorfenapyr ili ndi poizoni m'mimba komanso kupha tizilombo. Iwo ali amphamvu penetrability pa tsamba pamwamba, ali ena zokhudza zonse, ndipo ali ndi makhalidwe a sipekitiramu lonse insecticidal, kulamulira kwambiri zotsatira, yaitali yaitali ndi chitetezo. Liwiro lopha tizirombo ndi lofulumira, kulowa kwake kuli kolimba, ndipo mankhwala ophera tizilombo amakhala ochuluka. (Tizirombo titha kuphedwa pasanathe ola la 1 mutatha kupopera mbewu mankhwalawa, ndipo mphamvu zowongolera tsiku zimatha kupitilira 85%).
(3) Chlorfenapyr imakhala ndi mphamvu yoletsa tizilombo tolimbana ndi tizirombo, makamaka tizirombo ndi nthata zomwe zimagonjetsedwa ndi mankhwala ophera tizilombo monga organophosphorus, carbamate, ndi pyrethroids.
2. Kusakaniza kwa chlorfenapyr
Ngakhale chlorfenapyr ili ndi mitundu yambiri ya mankhwala ophera tizirombo, zotsatira zake ndi zabwino, ndipo kukana kwapano ndikocheperako. Komabe, wothandizira wamtundu uliwonse, ngati atagwiritsidwa ntchito yekha kwa nthawi yayitali, adzakhala ndi zovuta zokana pambuyo pake.
Chifukwa chake, pakupopera kwenikweni, chlorfenapyr nthawi zambiri imasakanizidwa ndi mankhwala ena kuti muchepetse kukana kwa mankhwala ndikuwongolera mphamvu.
(1) Chigawo chachlorfenapyr + emamectin
Pambuyo kuphatikiza chlorfenapyr ndi emamectin, ali sipekitiramu yotakata wa mankhwala ophera tizilombo, ndipo akhoza kulamulira thrips, nsikidzi, utitiri kafadala, akangaude ofiira, heartworms, chimanga borers, kabichi mbozi ndi tizirombo zina pa masamba, minda, mitengo ya zipatso ndi mbewu zina. .
Komanso, mutatha kusakaniza chlorfenapyr ndi emamectin, nthawi yokhalitsa ya medicament ndi yaitali, zomwe zimapindulitsa kuchepetsa nthawi yogwiritsira ntchito mankhwala ndi kuchepetsa mtengo wa alimi.
Nthawi yabwino yogwiritsira ntchito: mu gawo la 1-3 la tizilombo toyambitsa matenda, pamene kuwonongeka kwa tizilombo m'munda kuli pafupi 3%, ndipo kutentha kumayendetsedwa pafupifupi madigiri 20-30, zotsatira za ntchito ndizo zabwino kwambiri.
(2) chlorfenapyr +indoxacarb wosakanikirana ndi indoxacarb
Mukasakaniza chlorfenapyr ndi indoxacarb, sizingangopha tizirombo mwachangu (tizilombo timasiya kudya mukangokumana ndi mankhwala, ndipo tizirombo timafa mkati mwa masiku 3-4), komanso kukhalabe ndi mphamvu kwa nthawi yayitali. komanso oyenera mbewu. Chitetezo.
Kusakaniza kwa chlorfenapyr ndi indoxacarb kungagwiritsidwe ntchito polimbana ndi tizirombo ta lepidopteran, monga thonje la thonje, mbozi ya kabichi ya mbewu za cruciferous, njenjete ya diamondback, beet armyworm, ndi zina zotero, makamaka kukana njenjete za noctuid ndizodabwitsa.
Komabe, pamene othandizira awiriwa asakanizidwa, zotsatira za mazira si zabwino. Ngati mukufuna kupha mazira onse ndi akuluakulu, mungagwiritse ntchito lufenuron pamodzi.
Nthawi yabwino yogwiritsira ntchito: pakati ndi mochedwa magawo a kukula kwa mbewu, pamene tizirombo takula, kapena pamene 2, 3, ndi 4 mibadwo ya tizirombo imasakanizidwa, zotsatira za mankhwala zimakhala zabwino.
(3)chlorfenapyr + abamectin mankhwala
Abamectin ndi chlorfenapyr zimaphatikizidwa ndi mphamvu yodziwikiratu, ndipo imagwira ntchito motsutsana ndi thrips, mbozi, beet armyworm, leek Zonse zimakhala ndi mphamvu zowongolera.
Nthawi yabwino yogwiritsira ntchito: pakati ndi mochedwa magawo a kukula kwa mbewu, pamene kutentha kuli kochepa masana, zotsatira zake zimakhala bwino. (Kutentha kukatsika kuposa madigiri 22, ntchito yopha tizilombo ya abamectin imakhala yokwera).
(4) Kugwiritsa ntchito kosakanikirana kwa chlorfenapyr + zinamankhwala ophera tizilombo
Kuphatikiza apo, chlorfenapyr imathanso kusakanikirana ndi thiamethoxam, bifenthrin, tebufenozide, ndi zina zambiri kuti athe kuwongolera thrips, njenjete za diamondback ndi tizirombo tina.
Poyerekeza ndi mankhwala ena: chlorfenapyr makamaka ntchito kulamulira lepidopteran tizirombo, koma kuwonjezera chlorfenapyr, pali mankhwala ena awiri amenenso ndi zotsatira zabwino ulamuliro pa tizirombo lepidopteran, ndicho lufenuron ndi inde Wei.
Ndiye pali kusiyana kotani pakati pa mankhwala atatuwa? Kodi tiyenera kusankha bwanji mankhwala oyenera?
Othandizira atatuwa ali ndi zabwino ndi zovuta zawo. Muzogwiritsira ntchito, tikhoza kusankha wothandizira woyenera malinga ndi momwe zilili.
