2. Isetyenziselwa ntoni iDiquat?

IDiquat isetyenziselwa ukulawula ukhula emasimini, iigadi kunye nezinye iindawo ezingalinywanga. Ikwasetyenziselwa ukunyanga iingxaki zezityalo zasemanzini ezifana ne-algae kunye nokhula lwamanzi kwimizila yamanzi.
Izicelo kwezolimo
Kwezolimo, iDiquat isetyenziselwa ukususa ngokukhawuleza ukhula emasimini, ngakumbi ngexesha lokulungiswa komhlaba ngaphambi kokutyala izityalo.
Ulimo lwezitiya
Kwi-horticulture, iDiquat isetyenziselwa ukulawula ukhula kwiigadi kunye neengca ukugcina ukukhula kwezityalo okunempilo.
Ulawulo lwamanzi
I-Diquat ikwasetyenziselwa ukususa izityalo zasemanzini eziyingozi kwimithombo yamanzi ukuze kuqinisekiswe iindlela zamanzi ezigudileyo kunye nokulungelelana kwendalo yemithombo yamanzi.

3. Isebenza njani iDiquat?

I-Diquat inqanda i-photosynthesis ngokuthintela ikhonkco lothutho lwe-electron yesityalo, inkqubo ekhokelela ekubunjweni kwee-radicals zamahhala ngaphakathi kweseli yesityalo, ekugqibeleni itshabalalise izicubu zesityalo.
I-Diquat isebenza ngokukhawuleza kakhulu kwaye iimpawu zokubuna zidla ngokubonwa kwiiyure ezimbalwa, ngakumbi ekukhanyeni kwelanga.

4. Ithatha ixesha elingakanani ukuba iDiquat isebenze?

I-Diquat ngokuqhelekileyo iqala ukusebenza kwiiyure ezimbalwa zokusetyenziswa, kunye nezityalo ezibonisa iimpawu ezibonakalayo zokubola kunye nokufa ekugqibeleni phakathi kweentsuku ezi-1-2.
Ukukhanya kwelanga kunye nobushushu kunempembelelo ebalulekileyo kwisantya sesenzo seDiquat, kunye neziphumo ezikhawulezayo ezenzeka ekukhanyeni kwelanga.

IParaquat iqhele ukusetyenziswa kwiimeko apho kufuneka kutshatyalaliswe ukhula ngokupheleleyo, kanti iDiquat ifanelekile kuluhlu olubanzi lweendawo ezingezizo izityalo kunye nolawulo lwamanzi.

6. Ngaba iDiquat iyinxalenye yeParaquat yosapho lweekhemikhali?

I-Diquat kunye neParaquat, nangona zombini zikwiqela le-biphenyl leekhompawundi, azikho kwintsapho efanayo yeekhemikhali; I-Diquat yi-pyridine, kanti iParaquat iyinxalenye yeqela le-bipyridine leekhompawundi, ezinemichiza eyahlukeneyo kunye neendlela zokwenza.
I-Diquat yi-agent eyomeleleyo ye-oxidizing ephazamisa ngokukhawuleza indlela ye-photosynthesis yeeseli zezityalo, ekhokelela ekufeni kwezityalo ngokukhawuleza.
I-Paraquat ibulala izityalo ngokuthintela i-photosynthesis yazo kwaye inetyhefu enamandla kunye nexesha elide lokuhlala kwindawo.

7. Ndingayithenga phi iDiquat?

I-Diquat inokuthengwa kubanikezeli bezolimo, iivenkile ze-pesticide kunye namaqonga e-intanethi afana ne-POMAIS, ungaqhagamshelana nathi ngokushiya umyalezo kwi-intanethi.
