Isoxaflutole HPPD inhibitor herbicide no ka weed control

wehewehe huahana

He herbicide ʻōnaehana ʻo Isoxaflutole - ua unuhi ʻia i loko o ka mea kanu ma hope o ka absorption ma o nā aʻa a me nā lau a ua hoʻololi koke ʻia i loko o ka planta i ka diketonitrile hana biologically, a laila hoʻopau ʻia i ka metabolite inactive, 2-methylsulphonyl-4-trifluoromethylbenzoic acid.ʻO ka hana o ka huahana ma o ka inhibition o ka enzyme p-hydroxy phenyl pyruvate dioxygenase (HPPD), ka mea e hoʻohuli i ka p-hydroxy phenyl pyruvate i homogentisate, kahi hana nui i ka biosynthesis plastoquinone.Hoʻomalu ʻo Isoxaflutole i ka lau nahele ākea ma o ka hoʻomaʻemaʻe ʻana i nā mauʻu e puka mai ana a i ʻole i puka mai ma hope o ka lawe ʻana i ka herbicide ma o ka ʻōnaehana kumu.Ma hope o ka loaʻa ʻana o ka lau a i ʻole ke aʻa, hoʻololi koke ʻia ka isoxaflutole i kahi derivative diketonitrile (2-cyclopropyl-3-(2-mesyl-4-trifluoromethylphenyl)-3-oxopropanenitrile) ma ka wehe ʻana i ke apo isoxazole.

Hiki ke hoʻohana ʻia ka Isoxaflutole ma mua o ka puka ʻana, ka mea kanu a i ʻole ka mea kanu mua i hoʻohui ʻia i ka maile a me ka puka mua a i ʻole ma hope o ka puka mua ʻana i ke kō.Pono ka uku kiʻekiʻe no nā mea kanu mua.Ma nā hoʻokolohua kula, hāʻawi ka isoxaflutole i nā pae like o ka mana i nā lāʻau herbicide maʻamau akā ma nā helu noi ma kahi o 50 mau manawa haʻahaʻa.Mālama ʻo ia i nā nāhelehele triazine-kūpaʻa i ka wā i hoʻohana wale ʻia a i loko o nā hui.Manaʻo ka hui e hoʻohana ʻia i loko o nā hui ʻana, a me ka hoʻololi ʻana a i ʻole ke kaʻina me nā herbicide ʻē aʻe e hoʻopaneʻe i ka hoʻomaka ʻana o ke kū'ē.

ʻO Isoxaflutole, nona ka hapalua o ke ola o 12 mau hola a 3 mau lā, ma muli o ke ʻano o ka lepo a me nā mea ʻē aʻe, hoʻololi pū i ketonitrile i ka lepo.Mālama ʻia ʻo Isoxaflutole ma ka ʻili o ka lepo, e ʻae ʻia e lawe ʻia e nā hua mauʻu e ulu ana ma luna, ʻoiai ʻo diketonitrile, nona ka hapalua o ke ola o 20 a 30 mau lā, komo i ka lepo a lawe ʻia e nā aʻa mea kanu.Ma nā mea kanu ʻelua a ma ka lepo, hoʻololi ʻia ka diketonitrile i ka waikawa benzoic herbicidally inactive.

ʻAʻole pono e hoʻopili ʻia kēia huahana i nā ʻāina one a i ʻole nā ​​​​ʻeleʻele a i ʻole i nā lepo me ka liʻiliʻi o 2% o nā mea organik.I mea e pale aku ai i nā mea ʻawaʻawa i nā iʻa, nā mea kanu wai a me nā invertebrates, pono ka 22 mika buffer zone no ka pale ʻana i nā wahi koʻikoʻi, e like me nā ʻāina wai, nā loko, nā loko a me nā muliwai.
