I tēnei wā o ia tau, ka puta mai he tini o ngā pepeke (ngā pepeke taua, Spodoptera littoralis, Spodoptera litura, Spodoptera frugiperda, me ētahi atu), ka kino rawa atu ki ngā hua. Hei patu pepeke whānui, he pai te pānga o te chlorfenapyr ki ēnei pepeke.
1. Ngā āhuatanga o te chlorfenapyr
(1) He whānui ngā momo patu pepeke a te Chlorfenapyr, ā, he whānui hoki ngā whakamahinga. Ka taea te whakamahi hei whakahaere i ngā momo pepeke maha pērā i te Lepidoptera me te Homoptera i runga i ngā huawhenua, ngā rākau hua, me ngā hua whenua, pērā i te pūrerehua taimana, te kutukutu kāpeti, te kutukutu pīti, me te twill. He tino whai hua ngā pepeke huawhenua pērā i te pūrerehua noctuid, te pepeke kāpeti, te aphid kāpeti, te kaimaina rau, te thrips, me ētahi atu, inā koa ki ngā pepeke pakeke o te Lepidoptera.
(2) He pānga whakamate puku, he pānga whakamate pā hoki tō te Chlorfenapyr ki ngā pepeke. He kaha te uru ki te mata o te rau, he pānga pūnaha tōna, ā, he whānui te whānuitanga o ngā patu pepeke, he kaha te pānga whakahaere, he roa te pānga me te haumaru. He tere te tere o te patu pepeke, he kaha te uru, ā, he tino pai te patu pepeke. (Ka taea te whakamate i ngā pepeke i roto i te 1 hāora i muri i te rehu, ā, ka eke te pai o te whakahaere i te rā ki te neke atu i te 85%).
(3) He kaha te pānga whakahaere a te Chlorfenapyr ki ngā pepeke ātete, inā koa mō ngā pepeke me ngā mite e ātete ana ki ngā patu pepeke pēnei i te organophosphorus, te carbamate, me te pyrethroids.
2. Te whakaranu i te chlorfenapyr
Ahakoa he whānui te whānuitanga o ngā patu pepeke o te chlorfenapyr, he pai hoki te pānga, ā, he iti noa te ātete o nāianei. Heoi, ko tētahi momo rongoā, ki te whakamahia ko ia anake mō te wā roa, ka tino pāngia e ngā raruraru ātete i te wā e whai ake nei.
Nō reira, i te wā e rehuhia ana, me whakaranu pinepine te chlorfenapyr me ētahi atu rongoā hei whakaroa i te whakaputanga o te ātete rongoā me te whakapai ake i te pānga whakahaere.
(1) Te matū ochlorfenapyr + emamectin
I muri i te whakakotahitanga o te chlorfenapyr me te emamectin, he whānuitia ngā momo patu pepeke, ā, ka taea te whakahaere i ngā thrips, ngā pepeke haunga, ngā pītau puruhi, ngā pungawerewere whero, ngā kutukutu ngākau, ngā pepeke kānga, ngā anuhe kāpeti me ētahi atu pepeke i runga i ngā huawhenua, ngā mara, ngā rākau hua me ētahi atu hua whenua.
Heoi anō, i muri i te whakaranu i te chlorfenapyr me te emamectin, ka roa te wā e mau ai te rongoā, he mea whai hua tēnei hei whakaiti i te auau o te whakamahinga o te rongoā, hei whakaiti hoki i te utu whakamahinga a ngā kaimahi pāmu.
Te wā pai rawa atu mō te tono: i te wāhanga 1-3 o ngā tau o ngā pepeke, ina tata ki te 3% te kino o ngā pepeke i te mara, ā, ka whakahaeretia te pāmahana i te 20-30 nekehanga, ko te hua o te tono te mea tino pai.
(2) te chlorfenapyr +indoxacarb i konatunatua ki te indoxacarb
I muri i te whakaranu i te chlorfenapyr me te indoxacarb, kāore e taea te patu tere i ngā pepeke (ka mutu tonu te kai a ngā pepeke i muri i te pā atu ki te patu pepeke, ā, ka mate ngā pepeke i roto i ngā rā 3-4), engari ka mau tonu hoki tōna whai huatanga mō te wā roa, he mea pai ake hoki mō ngā hua whenua. Haumaru.
Ka taea te whakamahi i te ranunga o te chlorfenapyr me te indoxacarb hei whakahaere i ngā pepeke lepidopteran, pērā i te noke miro, te anuhe kāpeti o ngā hua cruciferous, te pūrerehua taimana, te noke pīti, me ētahi atu, inā koa te ātete ki te pūrerehua noctuid.
Heoi, ina whakaranua ēnei rongoā e rua, kāore e pai te pānga ki ngā hua manu. Ki te hiahia koe ki te patu i ngā hua manu me ngā pakeke, ka taea e koe te whakamahi ngātahi i te lufenuron.
Ko te wā pai mō te whakamahi: i waenganui me te mutunga o te tipu o te hua, ina pakeke haere ngā pepeke, ina whakaranua rānei te whakatupuranga tuarua, tuatoru, me te tuawhā o ngā pepeke, he pai te pānga o te rongoā.
(3)pūhui chlorfenapyr + abamectin
He hononga tahi te Abamectin me te chlorfenapyr, ā, he whai hua ki ngā thrips tino ātete, ngā anuhe, ngā noke pīti, me te rīki. He pai ngā pānga whakahaere katoa.
Te wā pai ki te whakamahi: i waenganui me te mutunga o te tipu o te hua, ina iti te pāmahana i te awatea, ka pai ake te pānga. (Ina iti iho te pāmahana i te 22 nekehanga, ka nui ake te kaha patu pepeke o te abamectin).
(4) Te whakamahinga whakaranu o te chlorfenapyr me ētahi atungā patu pepeke
Hei tāpiritanga, ka taea hoki te whakaranu i te chlorfenapyr me te thiamethoxam, te bifenthrin, tebufenozide, me ētahi atu hei whakahaere i ngā thrips, ngā pūrerehua diamondback me ētahi atu pepeke.
Ki te whakatauritea ki ētahi atu rongoā: ko te chlorfenapyr te nuinga o te wā e whakamahia ana hei whakahaere i ngā pepeke lepidopteran, engari i tua atu i te chlorfenapyr, e rua atu anō ngā rongoā he pai hoki ngā pānga whakahaere ki ngā pepeke lepidopteran, arā, ko te lufenuron me te indene Wei.
Nā, he aha te rerekētanga i waenganui i ēnei rongoā e toru? Me pēhea tātou e whiriwhiri ai i te rongoā tika?
He painga, he ngoikoretanga anō hoki ō ēnei kaihoko e toru. I roto i ngā mahi tūturu, ka taea e tātou te whiriwhiri i te kaihoko tika e ai ki te āhuatanga tūturu.
