Title (EN) HERBICIDAL PYRIDINE COMPOUNDS
(FR) COMPOSES DE PYRIDINE HERBICIDES
Abstract:
(EN) Herbicidal pyridine compounds of the formula (FORMULA) wherein Z and Y each represent a fluorine, chlorine, bromine, iodine, or hydrogen atom, or a trifluoromethyl, difluoromethyl, or chlorodifluoromethyl radical, provided that at least one of Z and Y is a halogenomethyl radical; R1 represents hydrogen or an alkyl radical of 1 to 4 carbon atoms; and R2 is a cyano group; a carboxyl group; one of a specified range of carboxamide or alkoxycarbonyl groups; a cyclohexyloxycarbonyl radical optionally substituted by one or more halogen atoms or methyl radicals; an alkenyloxycarbonyl radical in which the alkenyl group contains from 3 to 6 carbon atoms; a phenoxycarbonyl radical optionally bearing one or more halogen or methyl substituents; or a benzyloxycarbonyl radical, the phenyl group of which optionally bears one or more halogen or methyl substituents; and, in the case of compounds wherein R2 is a carboxyl group, salts thereof. The compounds are useful as selective herbicides for grass weeds in broad-leaved crops.
(FR) Composes de pyridine herbicides de formule (I): - (FORMULE) ou Z et Y representent chacun un fluor, un chlore, un brome, un iode, ou un atome d"hydrogene, ou un radical trifluoromethyl, un difluoromethyl, ou un radical chlorodifluoromethyl, pour autant qu"au moins Z ou Y soit un radical halogenomethyle; R1 represente l"hydrogene ou un radical alcoyl ayant 1 a 4 atomes de carbone; R2 est un groupe cyano, un groupe carboxyle, un groupe de la chaine specifique des groupes carboxamide ou alkoxycarbonyle, un radical cyclohexyloxycarbonyle pouvant etre substitue par un ou plusieurs atomes d"halogene ou radicaux methyl, un radical alkenyloxycarbonyl dans lequel le groupe alkenyle contient entre 3 et 6 atomes de carbone, un radical phenoxycarbonyl pouvant porter un ou plusieurs substituants halogene ou methyle, ou un radical benzyloxycarbonyle, dont le groupe phenyle peut porter un ou plusieurs substituants halogene ou methyle, et, dans les cas de composes ou R2 est un groupe carbonyle, les sels correspondants. Les composes sont des herbicides selectifs utiles a l"elimination des mauvaises herbes dans les cultures a larges feuilles.
