ʻO Tripyrasulfone, ua hōʻike ʻia ke ʻano hoʻohālike ma ka Figure 1, Kina Helu Hoʻolaha Mana Patent: CN105399674B, CAS: 1911613-97-2) ʻo ia ka mea mua o ka honua HPPD inhibitor herbicide i hoʻohana pono ʻia i ka lāʻau ma hope o ka puka ʻana a me ka mālama ʻana o ka lau. nā māla e hoʻomalu i nā mauʻu gramineous.
Mechanism o ka hana:
ʻO Triazole sulfotrione kahi ʻano herbicide hou e kāohi ana i ka p-hydroxyphenylpyruvate dioxygenase (HPPD), nāna e hoʻohuli i ka p-hydroxyphenylpyruvate i loko o ka mimi ma ke kāohi ʻana i ka hana o ka HPPD i nā mea kanu. Hoʻopaʻa ʻia ke kaʻina hana o ka waikawa ʻeleʻele, kahi e alakaʻi ai i ka synthesis abnormal o plastoquinone, a ʻo ka plastoquinone kahi cofactor nui o ka phytoene desaturase (PDS), a ʻo ka hōʻemi ʻana o ka plastoquinone ke keʻakeʻa nei i ka hana catalytic o PDS, a laila pili i ka biosynthesis o carotenoids. i ke kino i hoʻopaʻa ʻia, e alakaʻi ana i ka albinism lau a me ka make.
Nā hiʻohiʻona hana:
1. ʻO Tripyrasulfone kahi mea hoʻopaneʻe HPPD hou, ʻo ia ka manawa mua e hoʻohana pono ʻia ai ka mea hoʻopaneʻe HPPD i ka lāʻau ma hope o ke kanu ʻana a me ka mālama ʻana i ka lau ma ka māla raiki.
2. Hiki i ka Tripyrasulfone ke hoʻoponopono maikaʻi i ka pilikia o nā hua kūpaʻa a me ka barnyardgrass multi-resistant a me ka barnyardgrass.
3. ʻAʻohe pānaʻi kūʻē ma waena o Tripyrasulfone a me ka lāʻau lapaʻau koʻikoʻi o kēia manawa, hiki ke hoʻoponopono pono i nā pilikia paʻakikī o kēia manawa a me ka wā e hiki mai ana o ke kūʻē ʻana i ka mauʻu a me ka mauʻu barnyard.
4. Hiki ke hoʻohui ʻia ʻo Tripyrasulfone me ka nui kūpono o 2 methyl · methazopine e hoʻomaikaʻi i ka hoʻomalu ʻana o ka mauʻu ākea ākea a me ka mauʻu sedge a hoʻomaikaʻi i ka maikaʻi o ka weeding.
Nā mea e pono ai ka nānā ʻana:
1. Ma mua o ka hoʻohana ʻana, pono ia e hana i ka mālama pani ʻana e hōʻemi i ke kumu o ka mauʻu a me ka makahiki lau.
2. ʻAʻole hiki ke hui pū ʻia ʻo Tripyrasulfone me kekahi organophosphorus, carbamate, paclobutrazol insecticides a me fungicides a hoʻohana ʻia i loko o 7 mau lā. Hiki ke hoʻohana ʻia i hoʻokahi manawa i ka wā ulu a pau o ka laiki.
3. ʻAʻole ʻae ʻia ka hoʻolaha ʻana i ka fertilizer 7 mau lā ma mua a ma hope o ka noi ʻana.
ʻAʻole pāpā ʻia ka hoʻohui ʻana i ka hoʻohana ʻana i ka bensulfuron-methyl, pentaflusulfurochlor a me nā mea hoʻopiʻi ALS a me quinclorac.
4. He lā ka lewa, a ʻo ka mahana maikaʻi loa o ka pipi ʻana he 25 ~ 35 ℃. Inā ʻoi aku ka mahana ma mua o 38 ℃, ʻaʻole ʻōlelo ʻia ka pīpī ʻana. Inā he ua i loko o 8 mau hola ma hope o ka pīpī ʻana, pono ka pulupulu hou.
5. E hoʻokahe i ka wai ma mua o ka pīpī ʻana e hōʻoia i ka ʻoi aku o ka 2/3 o nā lau mauʻu i ʻike ʻia i ka wai a kau pono i ka pesticide; Ma hope o ka noi ʻana o ka pesticide, hoʻihoʻi ʻia ka wai i 5-7 cm i loko o 24-48 mau hola a mālama ʻia no nā lā ʻoi aku ma mua o 7 mau lā. ʻO ka lōʻihi o ka manawa mālama wai, ʻoi aku ka paʻa o ka hopena mana.
6. Pili kekahi mau ʻano laiki indica iā Tripyrasulfone, hiki ke alakaʻi i ka albinism lau, akā hiki ke hoʻihoʻi hou ʻia, me ka ʻole o ka hoʻohua ʻana i ka laiki.
Hōʻuluʻulu manaʻo:
He laulā nui ka Tripyrasulfone i nā lāʻau lapaʻau a me ka hana ʻana i ka weeding ma hope o ke kanu ʻana, ʻoi aku hoʻi no ka Echinochloa crus-galli, Leptochloa chinensis, Monochoria vaginalis a me Eclipta prostrata, a ʻaʻohe kū kūʻē kūʻē me nā herbicides nui o kēia manawa i nā māla raiki, e like me cyhalochlor, pentafluorosulphonachlor a me dichloroquinoline acid. I ka manawa like, palekana ia no nā mea kanu raiki a kūpono no ka kanu ʻana i ka laiki a me nā māla kanu pololei, He mea hana kūpono ia e hoʻoponopono ai i ka pilikia o ka weeding kemikala ma ka pā paddy i kēia manawa - e kāohi i ka mauʻu barnyard a me ka millet, a ua nā manaʻo noiʻi ākea. Ma o nā hoʻāʻo he nui, ua ʻike ʻia ka nui o nā pūhui i wehewehe ʻia ma Tripyrasulfone he koho maikaʻi no nā lau mauʻu e like me Zoysia japonica, bermudagrass, tall fescue, bluegrass, ryegrass, paspalum kahakai, a hiki ke hoʻomalu i nā mauʻu kī nui a me nā lau lau ākea. . ʻO nā hoʻāʻo ʻana o ka soybean, pulupulu, sunflower, ʻuala, lāʻau huaʻai a me nā mea kanu ma lalo o nā ʻano noi like ʻole i hōʻike i ka koho maikaʻi loa a me ka waiwai kūʻai.
