He meaʻai nui ka palaoa ma ka honua, a ʻoi aku ma mua o 40% o ka heluna kanaka o ka honua e ʻai i ka palaoa ma ke ʻano he meaʻai nui.Ua hoihoi ka mea kākau i nā lāʻau lapaʻau no nā mahina ʻai palaoa, a ua hoʻolauna pū ʻo ia i nā poʻe kahiko o nā ʻano lāʻau herbicides āpau.ʻOiai e puka mau ana nā mea hou e like me ka pinoxaden, e noʻonoʻo ana i ka mālama ʻana i kekahi mau nāhelehele kūikawā i nā māla palaoa a me ka pahuhopu hoʻokahi o nā mea hou e koi ai i nā huahana me kahi ʻano hana kūikawā a ʻaʻole maʻalahi e hana i ke kū'ē e hui pū ʻia e hoʻokō i ka hopena o elimination pālua , e ho'ēmi i ke kumukūʻai o ka hoʻohana 'ana i ka mahinaʻai, a me nā mea'ē aʻe,ʻo kekahi mau helehelena kahiko ka ikaika nui o ka weeding ma nā māla palaoa, a hoʻomau i ka hana i kahi hana i hikiʻole ke hoʻololi.ʻO ka huahana i wehewehe ʻia ma lalo nei ʻo ia ka nemesis o ka lau lau nahele i nā māla palaoa, ka mea hoʻohana maʻamau, haʻahaʻa haʻahaʻa haʻahaʻa, palekana loa no ka palaoa, a me ka waiwai.ʻO Florasulam kēia herbicide.

ʻO Florasulam ka lima o ka triazole pyrimidine i hoʻomohala maikaʻi ʻia e Dow AgroSciences i ka waena o 1990s ma hope o sulfentrazone, sulfentrazone, dicoxsulam a me sulfentrazone.ʻO nā lāʻau lapaʻau Sulfonamide.Ua hōʻike ʻia i ka makahiki 1998-1999, hoʻohana nui ʻia no ka mālama ʻana i nā mauhele ākea ākea ma nā māla palaoa.Ka hopena pale.Mai ka wā i hoʻokomo ʻia ai ma ka mākeke i ka makahiki 2000, ʻo ia kekahi o nā wahi ulu kūʻai kūʻai ʻo Dow AgroSciences, a ʻoi aku ka maikaʻi o ka ulu ʻana i nā makahiki i hala.

Mechanism of Action

Aia ʻo Florasulam i ka papa triazolopyrimidine sulfonamide o nā herbicides a he mea hoʻokae acetolactate synthase (ALS).Ma ke kāohi ʻana i ka acetolactate synthase i loko o nā mea kanu, ke keʻakeʻa nei ia i ka biosynthesis o ka ʻaoʻao kaulahao amino acids e like me valine, leucine a me isoleucine, no laila ua hoʻokaʻawale ʻia ka cell division, luku ʻia ka ulu maʻamau o nā nāhelehele, a make nā mauʻu.

Loaʻa iā Florasulam ka conductivity systemic, hiki ke hoʻopili ʻia e nā lau mea kanu a me nā aʻa, hoʻoili ʻia i ka mea kanu āpau, a hōʻiliʻili ʻia i loko o ka meristem e make ai ka mea kanu.No laila, pau loa ka nahele a ʻaʻole e hoʻi hou.

Palapala noi

Hoʻohana nui ʻia ʻo Florasulam no ka lāʻau ma hope o ka puka ʻana a me ka mālama ʻana i ka lau i nā māla palaoa e hoʻomalu i nā mauhele ākea ākea, me Artemisia somnifera, ʻeke kahu hipa, ʻāhiu ʻāhiu, pōʻino puaʻa, moa, moa pipi, pūnana nui, chakra raiki, Quail melemele, Maijiagong. a me nā mauhelehele ʻē aʻe paʻakikī, a he hopena maikaʻi loa ka pale ʻana i ka Ze Lacquer (Euphorbiaceae) paʻakikī i ka mālama ʻana i nā māla palaoa.Hiki ke ho'ohana 'ia no ka bale, kulina, soybean, pulupulu, sunflower, 'uala, hua pome, onion a me ka mau'u, ka hanai holoholona, ​​a pela aku.

Outlook

ʻOi aku ka maikaʻi o ka hoʻohana ʻana iā Florasulam a he herbicide hiki ʻole ke hoʻokuʻu ʻia no nā māla palaoa.Eia naʻe, ʻo ka hemahema o Florasulam ʻo ia ka wikiwiki o ka mauʻu make a me ka pae hoʻokahi.No laila, pono e hoʻohana piha i kona lōʻihi a pale i kona pōkole e hoʻonui i ke ola mākeke.
