ʻO Cyhalofop-butyl kahi herbicide systemic i hoʻomohala ʻia e Dow AgroSciences, i hoʻokumu ʻia ma Asia ma 1995. ʻO Cyhalofop-butyl ka palekana kiʻekiʻe a me ka hopena mana maikaʻi loa, a ua makemake nui ʻia e ka mākeke mai kona hoʻomaka ʻana. I kēia manawa, hoʻolaha ka mākeke o Cyhalofop-butyl ma nā wahi kanu raiki o ka honua, me Iapana, Kina, ʻAmelika Hui Pū ʻIa, Helene, Sepania, Farani, Italia, Pokukala a me Australia. I koʻu ʻāina, ua lilo ʻo Cyhalofop-butyl i mea hoʻomalu nui no nā mauʻu mauʻu e like me ka barnyardgrass a me ka stephenia ma nā pā paddy.
Hoʻolauna huahana
ʻO ka huahana ʻenehana Cyhalofop-butyl he paʻa keʻokeʻo keʻokeʻo, hiki ke hoʻoheheʻe ʻia i loko o ka hapa nui o nā mea hoʻoheheʻe organik, ʻaʻole hiki ke hoʻoheheʻe ʻia i ka wai, ʻo kona ʻano molekala C20H20FNO4, helu helu CAS: 122008-85-9
Mechanism o ka hana
ʻO Cyhalofop-butyl kahi herbicide conductive systemic. Ma hope o ka hoʻopili ʻia ʻana e nā lau a me nā lau lau o nā mea kanu, hele ia ma o ka phloem a hōʻiliʻili i ka meristem wahi o nā mea kanu, kahi e kāohi ai i ka acetyl-CoA carboxylase (ACCase) a synthesizes fatty acids. E ho'ōki, ʻaʻole hiki ke ulu a māhele like nā cell, ua luku ʻia ka ʻōnaehana membrane a me nā hale lipid ʻē aʻe, a make ka mea kanu.
Mea hoʻomalu
Hoʻohana nui ʻia ʻo Cyhalofop-butyl i nā māla kanu laiki, nā māla kanu pololei, a me nā māla transplanting, a hiki ke hoʻomalu a mālama i ka Qianjinzi, kanmai, nā mauʻu bran liʻiliʻi, crabgrass, foxtail, bran millet, heart leaf millet, pennisetum, maize, a me ka pipi pipi. ʻO ka mauʻu a me nā mauʻu gramineous ʻē aʻe, loaʻa iā ia kekahi hopena mana ma luna o ka mauʻu barnyardgrass ʻōpio, a hiki nō hoʻi ke kāohi pono i nā mauʻu i kū i ka quinclorac, sulfonylurea a me amide herbicides.
Nā mea maikaʻi o ka huahana
1. Ka hana herbicidal kiʻekiʻe
Ua hōʻike ʻo Cyhalofop-butyl i ka hana herbicidal i hoʻohālikelike ʻole ʻia e nā pesticides ʻē aʻe ma D. chinensis ma mua o ka pae 4-lau ma nā māla raiki.
2. Laulā o ka noi
ʻAʻole hiki ke hoʻohana ʻia ka cyhalofop-butyl ʻaʻole wale ma nā māla kanu laiki, akā pū kekahi i nā māla laiki a me nā māla kanu.
3. Hiki ke hoʻololi ikaika
Hiki ke hui pū ʻia ʻo Cyhalofop-butyl me ka penoxsulam, quinclorac, fenoxaprop-ethyl, oxaziclozone, a me nā mea ʻē aʻe, ʻaʻole ia e hoʻonui wale i ka spectrum herbicidal, akā hoʻopaneʻe hoʻi i ka puka ʻana o ke kū'ē.
4. Palekana kiʻekiʻe
He koho maikaʻi loa ka Cyhalofop-butyl i ka laiki, palekana i ka laiki, hoʻohaʻahaʻa wikiwiki i ka lepo a me ka wai paddy maʻamau, a palekana i nā mea kanu ma hope.
Manaʻo mākeke
ʻO ka laiki ka meaʻai nui loa o ka honua. Me ka hoʻonui ʻana o ka wahi kanu pololei o ka laiki a me ka piʻi ʻana o ke kūʻē ʻana o ka mauʻu mauʻu, ke koi mau nei ka mākeke no cyhalofop-butyl ma ke ʻano he herbicide maikaʻi a palekana i nā māla raiki. I kēia manawa, ke piʻi aʻe nei ka wahi i hana ʻia a me ka pōʻino o nā nāhelehele e like me Dwarfiaceae a me barnyardgrass ma nā māla raiki ma koʻu ʻāina, a ke piʻi nei ke kūʻē ʻana i ka sulfonylurea a me ka amide herbicides. Manaʻo ʻia e piʻi mau ka koi no cyhalofop-butyl i nā makahiki e hiki mai ana. A ma muli o ka pilikia o ke kū'ē ʻana, e hoʻomohala ʻia ka nui o ka cyhalofop-fop me kahi kiʻekiʻe (30% -60%), a e hoʻonui pū ʻia nā huahana hui me nā pesticides ʻē aʻe. I ka manawa like, me ka hoʻonui ʻana o ka pāhana hana o ka hale hana a me ka hoʻomaikaʻi ʻana i nā mea hana kaʻina hana, e hoʻonui hou ka mākeke o cyhalofop-butyl a me nā huahana i loaʻa cyhalofop-butyl a ʻoi aku ka ikaika o ka hoʻokūkū. Eia kekahi, me ka hoʻolaha ʻana o ka ʻenehana anti-flying spraying, ua kūpono ka cyhalofop-ester no ka hoʻohana ʻana e like me nā ʻano anti-flying spraying, a ʻo ka noi ʻenehana e hiki mai ana ke nānā aku i mua.
