1. Acetamiprid

ʻIke kumu:

ʻO ka Acetamiprid kahi lāʻau lāʻau lapaʻau hou me kahi hana acaricidal, e hana ana ma ke ʻano he insecticide systemic no ka lepo a me nā lau.Hoʻohana nui ʻia ia i ka mālama ʻana i ka laiki, ʻoi aku ka nui o nā mea kanu, nā lāʻau huaʻai, nā aphids kī, nā mea kanu, nā thrips, a me kekahi mau mea ʻeha lepidopteran.

Ke ala noi:

ʻO 50-100mg / L ka manaʻo, hiki ke hoʻomalu pono i ka pulupulu aphid, rapeseed meaʻai, peach heartworm liʻiliʻi, a me nā mea ʻē aʻe, hiki ke hoʻohana ʻia ʻo 500mg / L no ka mālama ʻana i ka moth māmā, ka moth ʻalani a me ka pear heartworm liʻiliʻi, a hiki ke pepehi i nā hua.

Hoʻohana nui ʻia ka acetamiprid e hoʻomalu i nā pests ma o ka pīpī ʻana, a ʻokoʻa ka nui o ka hoʻohana a i ʻole ka nui o ka lāʻau lapaʻau ma muli o ka ʻike o ka hoʻomākaukau.Ma nā kumulāʻau hua a me nā mea kanu kiʻekiʻe, 3% a 2,000 mau manawa o ka hoʻomākaukau ʻana, a i ʻole 5% o ka hoʻomākaukau ʻana he 2,500 a 3,000 mau manawa, a i ʻole 10% o ka hoʻomākaukau ʻana he 5,000 a 6,000 mau manawa, a i ʻole 20%.ʻO ka hoʻomākaukau ʻana o 10000 ~ 12000 mau manawa wai.A i ʻole 40% wai dispersible granules 20 000 ~ 25,000 manawa wai, a i ʻole 50% wai dispersible granules 25000 ~ 30,000 mau manawa wai, a i ʻole 70% wai dispersible granules 35 000 ~ 40 000 mau manawa wai, hoʻoheheʻe ʻia;i ka palaoa a me ka ʻaila pulupulu Ma nā mea kanu liʻiliʻi e like me nā mea kanu, maʻamau, hoʻohana ʻia ka 1.5 a i ka 2 grams o ka mea hoʻoikaika i kēlā me kēia 667 mika square, a hoʻohana ʻia ka 30 a 60 lita o ka wai.Hiki ke hoʻomaikaʻi i ka hoʻomalu ʻana o ka lāʻau lapaʻau i ka ʻaʻahu a me ka noʻonoʻo.

ʻO ke kumu nui:

1. ʻO nā insecticides nicotine chlorinated.Loaʻa i ka lāʻau lapaʻau nā hiʻohiʻona o ka spectrum insecticidal ākea, ka hana kiʻekiʻe, ka liʻiliʻi liʻiliʻi, ka hopena lōʻihi a me ka hopena wikiwiki, a loaʻa iā ia nā hana o ka hoʻopili ʻana a me ka ʻōpū o ka ʻōpū, a he hana ʻōnaehana maikaʻi loa.Hemiptera (Aphids, spider mites, whiteflies, mites, scale insects, etc.), Lepidoptera (Plutella xylostella, L. moth, P. sylvestris, P. sylvestris), Coleoptera (Echinochloa, Corydalis) A me ka huina wingworm pests (thuma) pono.No ka mea ʻokoʻa ke ʻano o ka hana o ka acetamiprid mai nā insecticides i hoʻohana ʻia i kēia manawa, loaʻa iā ia nā hopena kūikawā i nā pests kū'ē i ka organophosphorus, carbamates a me pyrethroids.

2. He mea maikaʻi ia no ka Hemiptera a me Lepidoptera pests.

3. He moʻo like ia me ka imidacloprid, akā ʻoi aku ka laulā o kāna spectrum insecticidal ma mua o ka imidacloprid, a he mana maikaʻi kona hopena i nā aphids ma ka kukama, ka ʻāpala, ka citrus a me ka paka.Ma muli o ke ʻano hana kūʻokoʻa o ka acetamiprid, he hopena maikaʻi ia i nā pests i kū i nā pesticides e like me organophosphorus, carbamate, a me pyrethroids.

2. Imidacloprid

1. Hoʻolauna kumu

ʻO ka imidacloprid kahi mea hoʻomakeʻa kiʻekiʻe o ka nicotine.Loaʻa iā ia ka laulā ākea, kiʻekiʻe-efficiency, haʻahaʻa haʻahaʻa, haʻahaʻa koena, ʻaʻole maʻalahi nā pests e hana kūʻē, a palekana ia no nā kānaka, nā holoholona, ​​​​nā mea kanu a me nā ʻenemi kūlohelohe.Loaʻa iā ia ka pilina, ka ʻōpū ʻawaʻawa a me ka hoʻopili ʻōnaehana.E kali no nā hopena he nui.Ma hope o ka ʻike ʻia ʻana o nā pests i ka mea hana, ua ālai ʻia ka hoʻokele maʻamau o ke kikowaena kikowaena, e make ai ka maʻi lolo.He hopena maikaʻi ka hopena wikiwiki, a loaʻa ka hopena mana kiʻekiʻe 1 lā ma hope o ka lāʻau lapaʻau, a ʻo ke koena manawa a hiki i 25 mau lā.Hoʻopili maikaʻi ka hopena a me ka mahana, kiʻekiʻe ka mahana, a maikaʻi ka hopena insecticidal.Hoʻohana nui ʻia e hoʻomalu i nā pests mouthparts.

2. Nā hiʻohiʻona hana

ʻO ka imidacloprid kahi mea hoʻomake ʻōnaehana hoʻokumu i ka nitromethylene a hana ʻo ia ma ke ʻano he acetylcholinesterase receptor no ka waikawa nicotinic.Hoʻopilikia ia i ka ʻōnaehana neʻe kaʻa o ka pest a hoʻopau i ka hoʻouna ʻana i nā hōʻailona kemika, me ke kū ʻole.Hoʻohana ʻia ia e hoʻomalu i nā pests mouthparts a me ko lākou mau ʻano pale.ʻO ka imidacloprid kahi hanauna hou o ka chlorinated nicotine insecticide me ka laulā ākea, ka hana kiʻekiʻe, ka haʻahaʻa haʻahaʻa, ke koena haʻahaʻa, ʻaʻole maʻalahi nā pests e hana i ke kū'ē, palekana no nā kānaka, nā holoholona, ​​​​nā mea kanu a me nā ʻenemi kūlohelohe, a loaʻa iā ia ka pilina, ka ʻōpū a me ka absorption systemic. .Nā hopena pharmacological lehulehu.Ma hope o ka ʻike ʻia ʻana o nā pests i ka mea hana, ua ālai ʻia ka hoʻokele maʻamau o ke kikowaena kikowaena, e make ai ka maʻi lolo.Loaʻa iā ia ka hopena wikiwiki wikiwiki, a he mana kiʻekiʻe kona hopena i hoʻokahi lā ma hope o ka lāʻau lapaʻau, a ʻo ke koena o ka manawa he 25 mau lā.Hoʻopili maikaʻi ka hopena a me ka mahana, kiʻekiʻe ka mahana, a maikaʻi ka hopena insecticidal.Hoʻohana nui ʻia e hoʻomalu i nā pests mouthparts.

3. Pehea e hoʻohana ai

Hoʻohana nui ʻia ia no ka pale ʻana a me ka mālama ʻana i nā pests omo mouthparts (hiki ke hoʻohana ʻia me ka haʻahaʻa haʻahaʻa haʻahaʻa o ka acetamiprid - haʻahaʻa haʻahaʻa me ka imidacloprid, kiʻekiʻe wela me ka acetamiprid), ka pale a me ka mālama ʻana e like me nā aphids, planthoppers, whiteflies, leafhoppers, thrips He mea maikaʻi nō hoʻi ia e kūʻē i kekahi mau mea ʻino o Coleoptera, Diptera a me Lepidoptera, e like me ka wīwī raiki, ka ilo maikaʻi ʻole raiki, a me ka miner lau.Akā ʻaʻole maikaʻi e kūʻē i nā nematodes a me nā spider ʻulaʻula.Hiki ke hoʻohana ʻia i ka laiki, ka palaoa, ke kulina, ka pulupulu, ka ʻuala, nā mea kanu, nā beets, nā lāʻau huaʻai a me nā mea kanu ʻē aʻe.Ma muli o kāna mau waiwai systemic maikaʻi loa, kūpono loa ia no ka noi ʻana e ka mālama ʻana i nā hua a me ka granulation.ʻO ka mea maʻamau, ʻo ka mea hana he 3 ~ 10 grams, i kāpī ʻia me ka wai a i ʻole ka hua.He 20 mau lā ka wā palekana.E hoʻolohe i ka pale i ka wā e hoʻohana ai i ka lāʻau lapaʻau, e pale i ka pili ʻana me ka ʻili a me ka inhalation o ka pauka a me ka lāʻau lapaʻau wai.E holoi i nā ʻāpana i ʻike ʻia me ka wai ma hope o ka hoʻohana ʻana.Mai hui pū me nā pesticides alkaline.ʻAʻole ʻōlelo ʻia ka pīpī ʻana ma lalo o ka lā ikaika e pale ai i ka hōʻemi ʻana i ka hopena.

E hoʻomalu i nā mea ʻino e like me Spiraea japonica, apple mites, peach aphid, pear hibiscus, leaf roller moth, whitefly, a me leafminer, e kāpī me 10% imidacloprid 4000-6000 mau manawa, a i ʻole 5% imidacloprid EC 2000-3000 manawa.Kāohi a me ka hoʻomalu: Hiki iā ʻoe ke koho iā Shennong 2.1% cockroach gel maunu.
