Abstract

1419788 Herbicidal application of 2-trifluoromethyl-4-quinolinols PFIZER INC 11 Jan 1973 [2 Aug 1972] 1625/73 Heading A5E [Also in Division C2] A method of inhibiting the growth of weeds comprises applying to the soil before emergence of the weeds or to the growing weeds a herbicidal amount of a compound having the formula: or an alkali metal, ammonia or a mono-, di-, or tri-alkylamine salt thereof, wherein each alkyl group has from 1 to 12 carbon atoms, wherein R 1 is hydrogen, halogen or alkyl of from 1 to 4 carbon atoms; each of R 2 and R 3 is hydrogen, halogen, alkyl of from 1 to 4 carbon atoms, alkanoyl of from 1 to 5 carbon atoms, nitro, cyano, trifluoromethyl, S(O)R 4 , S(O) 2 R 4 or -X-NR 4 R 5 , wherein each of R 4 and R 5 is hydrogen or alkyl of from 1 to 4 carbon atoms; and X is -CO- or -SO 2 - Preferred compounds are 3-bromo-5, 8-dichloro-2-trifluoromethyl-4-quinolinol, 3, 8-dichloro-2-trifluoromethyl-4-quinolinol and 3, 6-dichloro-8-methyl- 2-trifluoromethyl-4-quinolinol. The method may be a total herbicidal process or a selective weed-killer process. Specification 1419789 is referred to.
