Hoʻohālikelike ma waena o Dimethalin a me nā mea hoʻokūkū
ʻO ka Dimethylpentyl kahi herbicide dinitroaniline. Hoʻopili nui ʻia e nā ʻōpuʻu weed e ulu ana a hui pū ʻia me ka protein microtubule i nā mea kanu e kāohi i ka mitosis o nā mea kanu, e hopena i ka make ʻana o ka mauʻu. Hoʻohana nui ʻia ia ma nā ʻano māla maloʻo, me ka pulupulu a me ke kulina, a ma nā māla kanu lāʻau maloʻo. Ke hoʻohālikelike ʻia me nā huahana hoʻokūkū acetochlor a me trifluralin, ʻoi aku ka kiʻekiʻe o ka palekana o ka dimethalin, ʻo ia ka laina me ke kuhikuhi hoʻomohala maʻamau o ka palekana pesticide, ka mālama ʻana i ke kaiapuni a me ka haʻahaʻa haʻahaʻa. Manaʻo ia e hoʻomau i ka pani ʻana i ka acetochlor a me trifluralin i ka wā e hiki mai ana.
Loaʻa iā Dimethalin nā hiʻohiʻona o ka hana kiʻekiʻe, ākea ākea o ka pepehi ʻana i ka mauʻu, haʻahaʻa haʻahaʻa a me ke koena, palekana kiʻekiʻe i nā kānaka a me nā holoholona, a me ka adsorption lepo ikaika, ʻaʻole maʻalahi i ka leach, a me ka pili honua; Hiki ke hoʻohana ʻia ma mua a ma hope o ka ulu ʻana a ma mua o ke kanu ʻana, a ʻo kona lōʻihi a hiki i 45-60 mau lā. Hiki i hoʻokahi noi ke hoʻopau i ka pōʻino o ka weed i ka wā ulu o nā mea kanu.
Ka nānā 'ana i ke kūlana ho'omohala o ka 'oihana dimethalin honua
1. Māhele herbicide honua
I kēia manawa, ʻo ka herbicide i hoʻohana nui ʻia he glyphosate, e helu ana ma kahi o 18% o ka māhele mākeke herbicide honua. ʻO ka lua o ka herbicide he glyphosate, ʻo ia wale nō ka 3% o ka mākeke honua. ʻO nā pesticides ʻē aʻe he hapa liʻiliʻi. No ka mea, hana nui ka glyphosate a me nā pesticides i nā mea kanu transgenic. ʻO ka hapa nui o nā lāʻau lapaʻau i koi ʻia no ka hana ʻana i nā mea kanu ʻole GM ʻē aʻe ma lalo o 1%, no laila ua haʻahaʻa ka ʻike o ka mākeke herbicide. I kēia manawa, ʻoi aku ka nui o ka mākeke honua no ka dimethalin ma mua o 40,000 tons, ua manaʻo ʻia ke kumu kūʻai maʻamau he 55,000 yuan / ton, a ʻo ke kumukūʻai kūʻai kūʻai ma kahi o 400 miliona mau kālā, ʻo 1% ~ 2% o ka mākeke herbicide honua. unahi. No ka mea hiki ke hoʻohana ʻia e hoʻololi i nā lāʻau lapaʻau ʻino ʻē aʻe i ka wā e hiki mai ana, manaʻo ʻia e pālua ka mākeke ma muli o kona ulu nui ʻana.
2. Kūʻai ʻo dimethalin
I ka makahiki 2019, ʻo ke kūʻai aku ʻana o ka dimethalin i ke ao holoʻokoʻa he 397 miliona US kālā, ʻo ia ka 12th herbicide monomer nui loa ma ka honua. Ma ke ʻano o nā ʻāpana, ʻo ʻEulopa kekahi o nā mākeke kūʻai nui loa o ka dimethalin, ʻo 28,47% o ka māhele honua; ʻO Asia ka 27.32%, a ʻo nā ʻāina kūʻai nui ʻo India, Kina a me Iapana; ʻO ka ʻāina ʻo ʻAmelika ka nui o ʻAmelika Hui Pū ʻIa, Brazil, Kolombia, ʻEkuador a me nā wahi ʻē aʻe; He kūʻai liʻiliʻi ko Middle East a me Africa.
Hōʻuluʻulu manaʻo
ʻOiai he hopena maikaʻi ka dimethalin a he ʻoluʻolu kaiapuni, hoʻohana nui ʻia ia no nā mea kanu kālā e like me ka pulupulu a me nā mea kanu ma muli o kona kumukūʻai kiʻekiʻe i nā ʻano herbicides like a me ka hoʻomaka ʻana o ka mākeke. Me ka hoʻololi lohi o ka manaʻo o ka mākeke kūloko, ua piʻi wikiwiki ka noi no ka hoʻohana ʻana i ka dimethalin. ʻO ka nui o ka lāʻau lapaʻau maka i hoʻohana ʻia ma ka mākeke kūloko ua hoʻonui wikiwiki ʻia mai kahi o 2000 tons i ka makahiki 2012 a ʻoi aku ma mua o 5000 tons i kēia manawa, a ua hāpai ʻia a hoʻohana ʻia i ka laiki i lūlū ʻia, ke kulina a me nā mea kanu ʻē aʻe. Ke ulu wikiwiki nei kekahi ʻano hui pūhui kūpono.
Kūlike ʻo Dimethalin me ke ʻano o ka mākeke honua o ka hoʻololi mālie ʻana i nā mea ʻawaʻawa kiʻekiʻe a me nā koena pesticides kiʻekiʻe me nā pesticides aloha kaiapuni. He kiʻekiʻe ke kiʻekiʻe o ka hoʻohālikelike ʻana me ka hoʻomohala ʻana i ka mahiʻai hou i ka wā e hiki mai ana, a ʻoi aku ka nui o nā wahi hoʻomohala.
