I kēia kau o kēlā me kēia makahiki, nui ka poʻe ʻino e puka mai ana (army bug, Spodoptera littoralis, Spodoptera litura, Spodoptera frugiperda, a pēlā aku), e hōʻino nui ana i nā mea kanu. Ma ke ʻano he mea pepehi insecticidal ākea, he hopena maikaʻi ko chlorfenapyr i kēia mau mea ʻino.
1. Nā ʻano o ka chlorfenapyr
(1) Loaʻa iā Chlorfenapyr kahi ākea o nā insecticides a me nā ʻano hana like ʻole. Hiki ke hoʻohana ʻia e kāohi i nā ʻano mea ʻino e like me Lepidoptera a me Homoptera ma nā mea kanu, nā lāʻau hua, a me nā mea kanu mahina ʻai, e like me ka diamondback moth, cabbage worm, beet armyworm, a me twill. He nui nā mea ʻino mea kanu e like me ka noctuid moth, cabbage borer, cabbage aphid, leafminer, thrips, a pēlā aku, ʻoi aku hoʻi i nā pākeke o nā mea ʻino Lepidoptera, he mea kūpono loa ia.
(2) Loaʻa iā Chlorfenapyr ka hopena make ʻōpū a me ka hoʻopā ʻana i nā mea ʻino. Loaʻa iā ia ka ikaika o ke komo ʻana ma ka ʻili o ka lau, he hopena ʻōnaehana kekahi, a he mau ʻano o ka laulā ākea o ka insecticidal, ka hopena kaohi kiʻekiʻe, ka hopena lōʻihi a me ka palekana. He wikiwiki ka wikiwiki o ka insecticidal, ikaika ke komo ʻana, a ua ʻano kikoʻī ka insecticide. (Hiki ke pepehi ʻia nā mea ʻino i loko o 1 hola ma hope o ka pīpī ʻana, a hiki i ka pono o ka kaohi o ka lā ke hiki aku ma mua o 85%).
(3) Loaʻa iā Chlorfenapyr kahi hopena kaohi kiʻekiʻe e kūʻē i nā mea ʻino kūʻē, ʻoi aku hoʻi no nā mea ʻino a me nā mites i kūʻē i nā pesticides e like me organophosphorus, carbamate, a me pyrethroids.
2. Ka hoʻohuihui ʻana o ka chlorfenapyr
ʻOiai he ākea ka laulā o nā insecticides o ka chlorfenapyr, maikaʻi nō hoʻi ka hopena, a haʻahaʻa ke kū'ē o kēia manawa. Eia nō naʻe, ʻo kēlā me kēia ʻano mea hana, inā hoʻohana wale ʻia no ka manawa lōʻihi, e loaʻa nō nā pilikia kū'ē i ka pae hope.
No laila, i ka pīpī maoli ʻana, pono e hui pinepine ʻia ka chlorfenapyr me nā lāʻau ʻē aʻe e hoʻolohi i ka hanauna o ke kūʻē ʻana i ka lāʻau a hoʻomaikaʻi i ka hopena kaohi.
(1) Hui ochlorfenapyr + emamectin
Ma hope o ka hui pū ʻana o ka chlorfenapyr a me ka emamectin, he ākea ka laulā o nā insecticides, a hiki ke kāohi i nā thrips, nā ʻōpala pilau, nā ʻūlū flea, nā nananana ʻulaʻula, nā ilo puʻuwai, nā borers kulina, nā anuhe kāpeti a me nā mea ʻino ʻē aʻe ma nā mea kanu, nā mahina ʻai, nā lāʻau hua a me nā mea kanu ʻē aʻe.
Eia kekahi, ma hope o ke kāwili ʻana i ka chlorfenapyr a me ka emamectin, ua lōʻihi ka manawa o ka lāʻau lapaʻau, he mea pono ia e hōʻemi i ke alapine o ka hoʻohana ʻana i ka lāʻau lapaʻau a hōʻemi i ke kumukūʻai hoʻohana o nā mahiʻai.
ʻO ka manawa kūpono loa o ka hoʻopili ʻana: i ke kahua 1-3 o nā mea ʻino, i ka wā e pili ana ka pōʻino o nā mea ʻino i ke kula ma kahi o 3%, a ua kaohi ʻia ka mahana ma kahi o 20-30 degere, ʻoi aku ka maikaʻi o ka hopena o ka hoʻopili ʻana.
(2) chlorfenapyr +indoxacarb i hui pū ʻia me ka indoxacarb
Ma hope o ke kāwili ʻana i ka chlorfenapyr a me ka indoxacarb, ʻaʻole hiki iā ia ke pepehi koke i nā mea ʻino (e pau koke ka ʻai ʻana o nā mea ʻino ma hope o ka hoʻopili ʻana i ka pesticide, a e make nā mea ʻino i loko o 3-4 mau lā), akā e mālama pū i ka pono no ka manawa lōʻihi, ʻoi aku ka kūpono no nā mea kanu. Palekana.
Hiki ke hoʻohana ʻia ka hui ʻana o chlorfenapyr a me indoxacarb e kāohi i nā mea ʻino lepidopteran, e like me ka pulupulu bollworm, ka anuhe kāpeti o nā mea kanu cruciferous, ka moth diamondback, ka beet armyworm, a me nā mea ʻē aʻe, ʻoi aku ka kupaianaha o ke kūʻē ʻana i ka moth noctuid.
Eia nō naʻe, i ka wā e hui pū ʻia ai kēia mau mea ʻelua, ʻaʻole maikaʻi ka hopena ma nā hua. Inā makemake ʻoe e pepehi i nā hua a me nā pākeke, hiki iā ʻoe ke hoʻohana pū i ka lufenuron.
ʻO ka manawa kūpono loa o ka hoʻopili ʻana: i ka wā waena a me ka hopena o ka ulu ʻana o ka mea kanu, i ka wā e ʻelemakule ai nā mea ʻino, a i ʻole i ka wā e hui pū ʻia ai ka hanauna 2, 3, a me 4 o nā mea ʻino, maikaʻi ka hopena o ka lāʻau lapaʻau.
(3)chlorfenapyr + abamectin pūhui
Ua hui pū ʻia ʻo Abamectin lāua ʻo chlorfenapyr me ka hopena synergistic maopopo, a he kūpono ia e kūʻē i nā thrips kūpaʻa loa, nā anuhe, nā ilo beet, a me ka leek. Loaʻa iā lākou nā hopena kaohi maikaʻi.
ʻO ka manawa kūpono loa e hoʻohana ai: i ka wā waena a me ka hopena o ka ulu ʻana o ka mea kanu, i ka wā e haʻahaʻa ai ka mahana i ke ao, ʻoi aku ka maikaʻi o ka hopena. (Ke haʻahaʻa ka mahana ma mua o 22 degere, ʻoi aku ka kiʻekiʻe o ka hana insecticidal o ka abamectin).
(4) Hoʻohana like ʻia o chlorfenapyr + nā mea ʻē aʻenā mea pepehi lāʻau make
Eia kekahi, hiki ke hoʻohui ʻia ka chlorfenapyr me ka thiamethoxam, bifenthrin, tebufenozide, a me nā mea ʻē aʻe e kāohi i nā thrips, nā moth diamondback a me nā mea ʻino ʻē aʻe.
Hoʻohālikelike ʻia me nā lāʻau lapaʻau ʻē aʻe: hoʻohana nui ʻia ka chlorfenapyr e kāohi i nā mea ʻino lepidopteran, akā ma waho aʻe o ka chlorfenapyr, aia ʻelua mau lāʻau lapaʻau ʻē aʻe i loaʻa nā hopena kaohi maikaʻi i nā mea ʻino lepidopteran, ʻo ia hoʻi ʻo lufenuron lāua ʻo indene Wei.
No laila, he aha ka ʻokoʻa ma waena o kēia mau lāʻau lapaʻau ʻekolu? Pehea mākou e koho ai i ka lāʻau lapaʻau kūpono?
Loaʻa i kēia mau mea ʻekolu ko lākou mau pono a me nā hemahema. Ma nā hana maoli, hiki iā mākou ke koho i ka mea kūpono e like me ke kūlana maoli.
