I kēia kau o kēlā me kēia makahiki, puka mai ka nui o nā mea ʻino (ka pūʻali koa, Spodoptera littoralis, Spodoptera litura, Spodoptera frugiperda, etc.), e hōʻino nui ana i nā mea kanu.Ma ke ʻano he lāʻau insecticidal ākea ākea, he hopena maikaʻi ka chlorfenapyr i kēia mau pest.
1. Nā hiʻohiʻona o ka chlorfenapyr
(1) Loaʻa iā Chlorfenapyr kahi ākea ākea o nā insecticides a me kahi ākea o nā noi.Hiki ke hoʻohana ʻia no ka hoʻomalu ʻana i nā ʻano mea ʻino e like me Lepidoptera a me Homoptera ma nā mea kanu, nā kumulāʻau hua, a me nā mea kanu o ke kula, e like me ka moth diamondback, ka ilo kāpeti, ka beet armyworm, a me ka ʻuala.ʻO ka nui o nā mea kanu meaʻai e like me ka noctuid moth, kāpeti borer, cabbage aphid, leafminer, thrips, a me nā mea ʻē aʻe, ʻoi aku ka maikaʻi o ka poʻe mākua o nā pests Lepidoptera.
(2) Loaʻa iā Chlorfenapyr ka ʻōpū a me nā hopena pepehi kanaka i nā mea ʻino.Loaʻa iā ia ka hiki ke komo ma ka ʻili o ka lau, loaʻa kekahi hopena systemic, a loaʻa nā ʻano o ka spectrum insecticidal ākea, ka hopena mana kiʻekiʻe, ka hopena lōʻihi a me ka palekana.ʻO ka wikiwiki o ka insecticidal wikiwiki, ikaika ke komo ʻana, a ʻoi aku ka maikaʻi o ka insecticide.(Hiki ke pepehi ʻia nā pests i loko o 1 hola ma hope o ka pīpī ʻana, a ʻoi aku ka maikaʻi o ka mana o ka lā ma mua o 85%).
(3) Loaʻa i ka Chlorfenapyr ka hopena hoʻomalu kiʻekiʻe e kūʻē i nā pests kū'ē, ʻoi aku ka nui o nā pests a me nā mite i kū i nā pesticides e like me organophosphorus, carbamate, a me pyrethroids.
2. Ka hui 'ana o ka chlorfenapyr
ʻOiai he ākea ākea ka chlorfenapyr o nā insecticides, maikaʻi nō hoʻi ka hopena, a haʻahaʻa haʻahaʻa ke kū'ē i kēia manawa.Eia naʻe, ʻo kēlā me kēia ʻano mea hana, inā hoʻohana wale ʻia no ka manawa lōʻihi, e loaʻa maoli nā pilikia kūʻē i ka pae hope.
No laila, i ka hoʻoulu ʻana maoli, pono e hui pinepine ʻia ka chlorfenapyr me nā lāʻau lapaʻau ʻē aʻe e hoʻolōʻihi i ka hanauna o ka lāʻau kūʻē a hoʻomaikaʻi i ka hopena mana.
(1) Huina ochlorfenapyr + emamectin
Ma hope o ka hui pū ʻana o ka chlorfenapyr a me ka emamectin, loaʻa iā ia kahi ākea ākea o nā insecticides, a hiki ke hoʻomalu i nā thrips, nā pilau pilau, nā nūnū puʻupuʻu, nā ʻulaʻula ʻulaʻula, nā puʻuwai, nā kuli kulina, nā anuhe kāpeti a me nā mea ʻino ʻē aʻe i nā mea kanu, nā māla, nā lāʻau hua a me nā mea kanu ʻē aʻe. .
Eia kekahi, ma hope o ka hoʻohui ʻana i ka chlorfenapyr a me ka emamectin, ua lōʻihi ka manawa mau o ka lāʻau lapaʻau, he mea maikaʻi ia e hōʻemi i ka pinepine o ka hoʻohana ʻana i ka lāʻau lapaʻau a hoʻemi i ke kumukūʻai hoʻohana o nā mahiʻai.
ʻO ka manawa maikaʻi loa o ka noi: ma ka 1-3 instar stage o nā pests, i ka wā e hōʻino ʻia ai ka pōʻino ma ke kula ma kahi o 3%, a mālama ʻia ka mahana ma kahi o 20-30 degere, ʻoi aku ka maikaʻi o ka hopena o ka noi.
(2) chlorfenapyr +ʻo ka indoxacarb i hui pū ʻia me ka indoxacarb
Ma hope o ka hoʻohui ʻana i ka chlorfenapyr a me ka indoxacarb, ʻaʻole hiki iā ia ke pepehi koke i nā pests (e pau ka ʻai ʻana o nā pests ma hope o ka hoʻopili ʻana i ka pesticide, a make nā pests i loko o 3-4 mau lā), akā mālama pū kekahi i ka pono no ka manawa lōʻihi. kūpono hoʻi no nā mea kanu.Palekana.
Hiki ke hoʻohana ʻia ka hui ʻana o ka chlorfenapyr a me indoxacarb e hoʻomalu i nā pests lepidopteran, e like me ka pulupulu bollworm, kāpeti caterpillar o nā mea kanu cruciferous, diamondback moth, beet armyworm, a me nā mea ʻē aʻe.
Eia naʻe, ke hui pū ʻia kēia mau mea ʻelua, ʻaʻole maikaʻi ka hopena i nā hua.Inā makemake ʻoe e pepehi i nā hua ʻelua a me nā pākeke, hiki iā ʻoe ke hoʻohana pū i ka lufenuron.
ʻO ka manawa maikaʻi loa o ka hoʻohana ʻana: i ka waena waena a me ka hope o ka ulu ʻana o ka hua, i ka wā i ʻelemakule ai nā mea ʻino, a i ka wā i hui pū ʻia ai ka 2nd, 3rd, a me 4th hanauna o nā pests, maikaʻi ka hopena o ka lāʻau.
(3)chlorfenapyr + abamectin pūhui
Hoʻohui ʻia ʻo Abamectin a me chlorfenapyr me ka hopena synergistic maopopo, a he mea maikaʻi ia e kūʻē i nā thrips kūpaʻa loa, nā anuhe, beet armyworm, leek Loaʻa nā hopena mana maikaʻi a pau.
ʻO ka manawa maikaʻi loa e hoʻohana ai: ma ka waena a me ka hopena o ka ulu ʻana o ka mea kanu, i ka wā e haʻahaʻa ai ka mahana i ka lā, ʻoi aku ka maikaʻi o ka hopena.(Ke emi ka mahana ma mua o 22 degere, ʻoi aku ka kiʻekiʻe o ka hana insecticidal o abamectin).
(4) Hoʻohana hui ʻia o chlorfenapyr + ʻē aʻepesticides
Eia kekahi, hiki ke hui pū ʻia ka chlorfenapyr me thiamethoxam, bifenthrin, tebufenozide, a me nā mea ʻē aʻe e hoʻomalu 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 pests lepidopteran, akā ma kahi o chlorfenapyr, aia ʻelua mau lāʻau lapaʻau ʻē aʻe i loaʻa nā hopena hoʻomalu maikaʻi i nā pests lepidopteran, ʻo ia ka lufenuron a me indene Wei.
No laila, he aha ka ʻokoʻa ma waena o kēia mau lāʻau ʻekolu?Pehea mākou e koho ai i ka lāʻau kūpono?
Loaʻa i kēia mau ʻelele ʻekolu ko lākou pono a me nā hemahema.Ma nā noi kūpono, hiki iā mākou ke koho i ka luna kūpono e like me ke kūlana maoli.
