IPinoxaden: Inkokeli kwiSibulali-zinambuzane sasemasimini eengqolowa

Igama eliqhelekileyo lesiNgesi yiPinoxaden; igama lekhemikhali yi-8-(2,6-diethyl-4-methylphenyl)-1,2,4,5-tetrahydro-7-oxo-7H- Pyrazolo[1,2-d][1,4,5]oxadiazepine-9-yl 2,2-dimethylpropionate; Ifomula yemolekyuli: C23H32N2O4; Ubunzima bemolekyuli obuhambelanayo: 400.5; Inombolo yokungena yeCAS: [243973-20-8]; ifomula yolwakhiwo iboniswe kuMfanekiso. Sisibulali-zinambuzane esisandula ukuvela nesikhethiweyo esaphuhliswa yiSyngenta. Saqaliswa ngo-2006 kwaye ukuthengiswa kwaso ngo-2007 kwadlula i-US$100 yezigidi.

Indlela yokusebenza

I-Pinoxaden ikwiqela elitsha le-phenylpyrazoline le-herbicides kwaye ingumthinteli we-acetyl-CoA carboxylase (ACC). Indlela esebenza ngayo ikakhulu kukuthintela ukwenziwa kwe-fatty acid, nto leyo ekhokelela ekuvalekeni kokukhula nokwahlukana kweeseli, kunye nokufa kwezityalo zokhula, kunye nokuqhuba kwenkqubo. Le mveliso isetyenziswa kakhulu njenge-herbicide emva kokuvela kwiintsimi zeenkozo ukulawula ukhula lwengca.

Isicelo

I-Pinoxaden sisibulali-zinambuzane esikhethayo, esihambisa ukhula lwengca ngendlela echanekileyo, esisebenza kakuhle kakhulu, esibanzi, kwaye sifunxwa ngokukhawuleza kwiziqu namagqabi. Ulawulo lokhula olunegramine oluvela ngonyaka emva kokuvela emasimini engqolowa nerhasi, njenge-sagebrush, i-Japanese sagebrush, i-wild oats, i-ryegrass, i-thorngrass, i-foxtail, ingca eqinileyo, i-serratia kunye ne-thorngrass, njl. Ikwanefuthe elihle lolawulo kwiingca eziqinileyo ezifana ne-ryegrass. Umthamo wesithako esisebenzayo yi-30-60 g/hm2. I-Pinoxaden ifanelekile kakhulu kwiinkozo zasentwasahlobo; ukuphucula ukhuseleko lwemveliso, kongezwa i-safener fenoxafen.

1. Ukuqala ngokukhawuleza. Emva kweveki e-1 ukuya kwe-3 emva kokuba iyeza lisetyenzisiwe, iimpawu ze-phytotoxicity ziyavela, kwaye i-meristem iyayeka ukukhula ngokukhawuleza kwaye ivuvukale ngokukhawuleza;

2. Ukhuseleko oluphezulu kwindalo. Ikhuselekile kwisivuno sangoku sengqolowa, irhasi kunye nokhuseleko lwezinto eziphilayo olungajoliswanga, ikhuselekile kwizityalo ezilandelayo kunye nokusingqongileyo;

3. Indlela esebenza ngayo ihlukile kwaye umngcipheko wokuxhathisa uphantsi. IPinoxaden inesakhiwo esitsha seekhemikhali esineendawo ezahlukeneyo zokusebenza, nto leyo eyandisa indawo yayo yophuhliso kwicandelo lolawulo lokuxhathisa.
