Description
Selektive herbicide preparater som inneholder
fenylkarbamater.
Denne oppfinnelse angår preparater med selektiv herbicid virkning inneholdende nye substituerte fenylkarbamater.
Herbicide forbindelser basert på fenylkarbamidsyrer er tidligere kjent. I J. Agric. Food Chem., vol. 2, side 356-363, 1954 er f.eks. beskrevet forskjellige estere av N-fenylkarbamidsyrer, f.eks. isopropyl-N-fenylkarbamat med herbicid virkning. Disse forbindelser har imidlertid en utilfredsstillende breddevirk-ning, da vesentlige akerugress, som f.eks. svineblom (Senecio vulga-ris)o.a.f påvirkes bare lite eller ikke i det hele tatt.
Videre er det i belgisk patent 661 399 beskrevet herbicid virksomme urinstoffderivater med den generelle formel:
hvor X betyr oksygen eller svovel, og valensstrekene betyr forskjellige mettede rester.
Disse urinstoffderivater egner seg imidlertid ikke til anvendelse i nytteplantekulturer, som f.eks. sukkerroer og erter, som skades av disse derivater.
Det er nu funnet at forbindelser med den generelle formel
hvor R^ er cykloalkyl med 5-8 karbonatomer, alkyl med 1-8 karbonatomer som eventuelt kan være substituert med et kloratom, eller fenyl som eventuelt kan være substituert med en lavere alkyl-eller alkoksygruppe, R_ er hydrogen eller lavere alkyl, R., er lavere alkyl, og X er oksygen eller svovel, med unntagelse av forbindelser der X er oksygen og R^ cykloalkyl, alkyl eller fenyl som eventuelt er substituert med lavere alkyl, oppviser en god herbicid virkning og kan spesielt anvendes i nytteplantekulturer uten fare for at disse kulturer skades.
Ved anvendelse av de nye forbindelser skades således ikke ømfintlige dikotyle plantearter som f.eks. sukkerroer og erter, når kulturene behandles efter spiring.
De nye forbindelser som anvendes i preparatene i henhold til oppfinnelsen, kan fremstilles ved metoder som anvendes for syntese av karbamidsyreestere, f.eks. som beskrevet i hoved-patentet.
I det følgende er angitt eksempler på forbindelser
som kan anvendes i preparatene.
Sammenlignings forsøk
De nedenstående forbindelser i en anvendt mengde på
1 kg aktivt stoff pr. hektar, emulgert resp. suspendert i 600 liter vann pr. hektar, ble sprøytet på kulturplanter og ugress efter spiring. 14 dager efter behandlingen ble resultatet av bekjempelsen bedømt efter bedømmelsesskjemaet 0-10, hvor 0 = total utryddelse og 10 = ubeskadiget. Som det fremgår av tabel-len, ble ugresset utryddet ved hjelp av de aktive stoffer som anvendes i henhold til oppfinnelsen, uten at kulturplantene ble skadet, mens midlene fra det belgiske patent 661 399 ikke opp-viste noen selektive egenskaper.
Claims (1)
- Selektive herbicide preparater som inneholder fenylkarbamater, karakterisert ved at de som en ve-sentlig aktiv bestanddel inneholder et N-(3-karbamoyloksyfenyl)-karbamat eller et N- (3-karbamoyloksyfenyl)-tiolkarbamat med for-melen:hvori er cykloalkyl med 5-8 karbonatomer, alkyl med 1-8 karbonatomer som eventuelt kan være substituert med et kloratom, eller fenyl som eventuelt kan være substituert med en lavere alkyl- elleralkoksygruppe, R2 er hydrogen eller lavere alkyl, R^ er lavere alkyl, og X er oksygen eller svovel, med unntagelse av forbindelser der X er oksygen og R^ cykloalkyl, alkyl eller fenyl som eventuelt er substituert med lavere alkyl.
