Florasulam

Ingqolowa sisityalo sokutya esibalulekileyo ehlabathini, kwaye ngaphezu kwe-40% yabemi behlabathi batya ingqolowa njengokutya okusisiseko.Umbhali usanda kuba nomdla kwimichiza yokutshabalalisa ukhula kumasimi engqolowa, kwaye uye wazisa ngokulandelelanayo amagqala emichiza eyahlukeneyo yengqolowa.Nangona ii-arhente ezintsha ezifana ne-pinoxaden zihlala ziphuma, kuthathelwa ingqalelo ukuba ulawulo lokhula olukhethekileyo kumasimi engqolowa kunye nethagethi enye yeearhente ezintsha zifuna iimveliso ezinendlela eyodwa yokusebenza & akukho lula ukuvelisa ukuxhathisa ukuba kuxutywe ukufezekisa umphumo we ukupheliswa kabini , ukunciphisa iindleko zokusetyenziswa kwentsimi, njl. njl., obunye ubuso obudala busengamandla aphambili okuhlakula kumasimi engqolowa, kwaye baqhubeke bedlala indima engenakuthatyathelwa indawo.Imveliso echazwe ngezantsi yintshaba yokhula olunamagqabi abanzi kumasimi engqolowa, eyona ndlela ixhaphakileyo yokumila, ukumelana nobushushu obuphantsi kakhulu, ikhuselekile kakhulu kwingqolowa, kwaye iyonga.Lo mchiza wokutshabalalisa ukhula yiFlorasulam.

I-Florasulam yi-triazole yesihlanu ye-pyrimidine ephuhliswe ngempumelelo yi-Dow AgroSciences phakathi kwe-1990s emva kwe-sulfentrazone, i-sulfentrazone, i-dicoxsulam kunye ne-sulfentrazone.Imichiza yokutshabalalisa ukhula iSulfonamide.Kwaxelwa ngo-1998-1999, ikakhulu esetyenziselwa ukulawula ukhula olunamagqabi abanzi kumasimi engqolowa.Isiphumo sothintelo.Oko yabekwa kwimarike ngo-2000, ibe yenye yeendawo zokukhula kwentengiso ye-Dow AgroScience, kwaye izinga lokukhula libe lihle kakhulu kwiminyaka yakutshanje.

Indlela yokwenza

I-Florasulam yeyeklasi ye-triazolopyrimidine sulfonamide ye-herbicides kwaye iyi-acetolactate synthase (ALS) inhibitor eqhelekileyo.Ngokuthintela i-acetolactate synthase kwizityalo, ithintela i-biosynthesis ye-amino acids ye-side chain efana ne-valine, i-leucine kunye ne-isoleucine, ukwenzela ukuba ukuhlukana kweeseli kuvinjelwe, ukukhula okuqhelekileyo kokhula kutshatyalaliswa, kwaye ukhula luyafa.

I-Florasulam ine-systemic conductivity, enokuthi ifunnwe ngamagqabi esityalo kunye neengcambu, idluliselwe kwisityalo sonke sokhula, kwaye iqokelelwe kwi-meristem yokubangela ukufa kwezityalo.Ngoko ke, ukhula lubulawa ngokupheleleyo kwaye aluyi kuphinda lubekho.

 

Isicelo

I-Florasulam isetyenziswa kakhulu kunyango lwasemva kokuhluma kunye nonyango lwamagqabi kumasimi engqolowa ukulawula ukhula olunamagqabi abanzi, kuquka i-Artemisia somnifera, isipaji sikamalusi, udlwengulo lwasendle, intlekele yehagu, intshontsho lentshontsho, indlwane enkulu, irayisi chakra, izagwityi ezimthubi, Maijiagong kunye nolunye ukhula olunzima ukulawula, kwaye lube nefuthe elihle kakhulu lokuthintela kwi-Ze Lacquer (Euphorbiaceae) enzima ukuyilawula kumasimi engqolowa.Ingasetyenziselwa irhasi, umbona, iimbotyi zesoya, umqhaphu, ujongilanga, iitapile, iziqhamo zepome, itswele kunye nedlelo, idlelo, njl.

 

Outlook

I-Florasulam ineengenelo ezingcono zokusetyenziswa kwaye sisichiza sokutshabalalisa ukhula esingaphoswanga kumasimi engqolowa.Nangona kunjalo, into engalunganga yeFlorasulam kukuba isantya sengca efileyo sicotha kwaye indawo yesenzo ayinye.Ke ngoko, kuyafuneka ukusebenzisa ngokupheleleyo ixesha elide kwaye unqande ubufutshane bayo ukwandisa ubomi bentengiso.
