Gorosi chirimwa chekudya chakakosha munyika, uye chikamu chinodarika makumi mana kubva muzana chevagari vepasi vanodya gorosi sechikafu chikuru.Munyori achangobva kufarira mishonga yesora yemuminda yegorosi, uye akatevedzana akaunza veterans vemishonga yakasiyana-siyana yemumunda wegorosi.Kunyangwe maajenti matsva akadai sepinoxaden ari kugara achibuda, tichifunga kuti kutonga kwemamwe masora akakosha muminda yegorosi uye chinangwa chimwe chete chevamiririri vatsva kunoda zvigadzirwa zvine hunyanzvi hwekuita & zvisiri nyore kugadzira kuramba kusanganiswa kuti zviite kaviri kubvisa , kuderedza mari yekushandiswa kwemunda, nezvimwewo, zvimwe zviso zvekare zvichiri simba guru rekusakura muminda yegorosi, uye rinoramba richiita basa risingadzoreki.Chigadzirwa chinotsanangurwa pazasi ndechenemesis yemasora akatambanudzwa muminda yegorosi, iyo inonyanya kushandiswa kugadzirwa, yakaderera zvakanyanya tembiricha inoshingirira, yakachengeteka zvakanyanya pagorosi, uye ine mari.Mushonga wesora uyu inonzi Florasulam.

Florasulam ndiyo yechishanu triazole pyrimidine yakabudirira kugadzirwa neDow AgroScience pakati pemakore ekuma1990 mushure mesulfentrazone, sulfentrazone, dicoxsulam uye sulfentrazone.Sulfonamide mishonga yesora.Yakashumwa muna 1998-1999, inonyanya kushandiswa kudzora masora akafara-mashizha muminda yegorosi.Kudzivirira maitiro.Kubva zvakaiswa pamusika muna 2000, yanga iri imwe yeDow AgroSciences 'yekukura kwekutengesa, uye kukura kwave kwakanaka mumakore achangopfuura.

Nzira Yekuita

Florasulam ndeye triazolopyrimidine sulfonamide kirasi yemishonga yesora uye yakajairika acetolactate synthase (ALS) inhibitor.Nekudzivisa acetolactate synthase mumiti, inodzivisa biosynthesis yeside chain amino acids yakadai sevaline, leucine uye isoleucine, kuitira kuti kupatsanurwa kwesero kunodzivirirwa, kukura kwemasora kunoparadzwa, uye masora anofa.

Florasulam ine systemic conductivity, iyo inogona kutorwa nemashizha ezvirimwa nemidzi, inopfuudzwa kune yese sora chirimwa, uye inounganidzwa mune meristem kukonzera kufa kwechirimwa.Nokudaro, masora anourayiwa zvachose uye hapazove nekudzokazve.

Application

Florasulam inonyanya kushandiswa kugadzirisa tsinde nemashizha muminda yegorosi kudzora masora ane mashizha akafara, anosanganisira Artemisia somnifera, chikwama chemufudzi, chibharo chesango, dambudziko renguruve, chickweed, nhokwe yemombe, dendere hombe, rice chakra, yellow Quail, Maijiagong. uye mamwe masora akaoma-kudzora, uye ane yakanaka kwazvo inhibitory effect pane yakaoma-ku-control Ze Lacquer (Euphorbiaceae) muminda yegorosi.Inogonawo kushandiswa bhari, chibage, soya bhinzi, donje, sunflower, mbatatisi, pome michero, hanyanisi uye mafuro, mafuro, etc. Nguva yekushandisa yakakura, uye inogona kushandiswa nguva yechando isati yasvika kusvika pakutanga kwechirimo.

Outlook

Florasulam ine zvirinani zvekushandisa uye mushonga wesora usingapotse weminda yegorosi.Nekudaro, iyo yakashata yeFlorasulam ndeyekuti kumhanya kweuswa hwakafa kunononoka uye nzvimbo yekuita haina.Naizvozvo, zvinodikanwa kushandisa zvizere kureba kwayo uye kudzivirira hupfupi hwayo kuti uwedzere hupenyu hwemusika.
