Ukolweni uyisitshalo sokudla esibalulekile emhlabeni, futhi abantu abangaphezu kuka-40% emhlabeni badla ukolweni njengokudla okuyisisekelo.Umbhali usanda kuba nentshisekelo emithini yokubulala ukhula emasimini kakolo, futhi usethule ngokulandelanayo omakadebona bemithi ehlukahlukene yokubulala ukhula yasensimini kakolweni.Nakuba ama-ejenti amasha afana ne-pinoxaden ehlala ephuma, uma kucatshangelwa ukuthi ukulawulwa kokhula oluthile olukhethekile emasimini kakolweni kanye nokuhlosiwe okukodwa kwama-ejenti amasha kudinga imikhiqizo enendlela eyingqayizivele yokwenza futhi akulula ukukhiqiza ukumelana ukuze kuhlanganiswe ukuze kuzuzwe umphumela ukuqedwa kabili , ukunciphisa izindleko zokusetshenziswa kwensimu, njll., obunye ubuso obudala busengamandla amakhulu okuhlakula emasimini kakolweni, futhi bayaqhubeka nokudlala indima engenakushintshwa.Umkhiqizo ochazwe ngezansi uyizitha zokhula olunamaqabunga abanzi emasimini kakolweni, ukwakheka okuvame ukusetshenziswa kakhulu, ukumelana nokushisa okuphansi kakhulu, okuphephe kakhulu ukolweni, futhi ukonga.Lesi sibulala-khula yiFlorasulam.

I-Florasulam iyi-triazole pyrimidine yesihlanu eyakhiwe ngempumelelo yi-Dow AgroSciences maphakathi nawo-1990 ngemva kwe-sulfentrazone, i-sulfentrazone, i-dicoxsulam ne-sulfentrazone.Ama-herbicides e-sulfonamide.Kwabikwa ngo-1998-1999, ikakhulukazi esetshenziselwa ukulawula ukhula olunamaqabunga abanzi emasimini kakolo.Umphumela wokuvimbela.Selokhu yafakwa emakethe ngo-2000, bekungenye yezindawo zokukhula kwe-Dow AgroSciences, futhi izinga lokukhula libe lihle kakhulu eminyakeni yamuva nje.

Indlela Yokwenza

I-Florasulam ingeyesigaba se-triazolopyrimidine sulfonamide yama-herbicides futhi iyisivimbeli esivamile se-acetolactate synthase (ALS).Ngokuvimbela i-acetolactate synthase ezitshalweni, ivimbela i-biosynthesis yama-amino acid e-side chain afana ne-valine, i-leucine ne-isoleucine, ukuze kuvinjelwe ukuhlukana kwamaseli, ukukhula okuvamile kokhula kubhujiswe, futhi ukhula luyafa.

I-Florasulam ine-systemic conductivity, engamuncwa amaqabunga ezitshalo nezimpande, idluliselwe kuso sonke isitshalo sokhula, futhi iqoqwe ku-meristem ukuze ibangele ukufa kwesitshalo.Ngakho-ke, ukhula lubulawa ngokuphelele futhi ngeke luphinde lube khona.

Isicelo

I-Florasulam isetshenziswa kakhulu ekuhlumeni kwesiqu kanye nokwelashwa kwamaqabunga emasimini kakolweni ukulawula ukhula olunamaqabunga abanzi, okuhlanganisa i-Artemisia somnifera, isikhwama somalusi, ukudlwengula zasendle, inhlekelele yengulube, i-chickweed, i-chickweed yenkomo, isidleke esikhulu, i-rice chakra, i-quail ephuzi, i-Maijiagong kanye nolunye ukhula okunzima ukululawula, futhi lunomphumela omuhle kakhulu wokuvimbela ku-Ze Lacquer (Euphorbiaceae) okunzima ukuyilawula emasimini kakolweni.Ingabuye isetshenziselwe ibhali, ummbila, ubhontshisi wesoya, ukotini, ubhekilanga, amazambane, isithelo sepome, u-anyanisi namadlelo, amadlelo, njll. Isikhathi sokufaka isicelo sibanzi, futhi singasetshenziswa ngaphambi kobusika kuya ekuqaleni kwentwasahlobo.

I-Outlook

I-Florasulam inezinzuzo ezingcono zokufaka isicelo futhi iwumuthi obulala ukhula ongaphuthelwa wamasimu kakolweni.Kodwa-ke, okubi kwe-Florasulam ukuthi ijubane lotshani obufile lihamba kancane futhi indawo yokusebenza iyodwa.Ngakho-ke, kuyadingeka ukusebenzisa ngokugcwele ubude bayo futhi ugweme ukufushane kwayo ukuze ukwandise impilo yemakethe.
