Substituted N-aryl[1,2,4]triazolo[1,5-a]pyridine- 2-sulfonamide compounds of formula (I), such as N-(2,6-difluorophenyl)-5-methoxy-7-methyl[1,2,4]triasolo-[1,5- a]pyridine-2-subfonamide N-(4-bromo-1-methyl-3-pyrazolyl)- 8-chloro-5-methoxy[1,2,4]triasolo[1,5-a]pyridine-2 sulfonamide and N-(2-fluoro-4-methyl-3-pyridinyl)-8-ethoxy-6- chloro[1,2,]triazolo[1,5-a]pyridine-2-sulfonamide, were prepared by condensation of a 2-chlorosulfonyl[1,2,4-triazolo[1,5- a]pyridine compound with an aryl amine. The compounds prcpared were found to possess excellent herbicidal activity on a broad spectrum of vegetation at low application rates.

Cette invention concerne des composés substitués de formule (I) au N-aryl[1,2,4]triazolo[1,5-a]pyridine-2-sulfonamide, tels que du N-(2,6-difluorophényl)-5-méthoxy-7-méthyl [1,2,4]triazolo-[1,5-a]pyridine-2-sulfonamide, du N-(4-homo-1-méthyl-3-pyrazolyl)-8-chloro-5-méthoxy[1,2,4]triazolo [1,5-a]pyridine-2-sulfonamide, et du N-(2-fluoro-4-méthyl-3-pyridinyl)-8-éthoxy-6-chloro [1,2,4]triazolo [1,5-a]pyridine-2-sulfonamide, qu'on a préparés en faisant condenser un composé de 2-chlorosulfonyl [1,2,4]-triazolo[1,5-a] pyridine avec une arylamine. On a découvert que les composés ainsi préparés possèdent une excellente activité herbicide sur une gamme étendue de végétaux à faibles doses d'application.
