Title
(EN) PYRIDAZINONE HERBICIDES AND PYRIDAZINONE INTERMEDIATES USED TO PREPARE A HERBICIDE
(FR) HERBICIDES DE PYRIDAZINONE ET INTERMÉDIAIRES DE PYRIDAZINONE UTILISÉS POUR PRÉPARER UN HERBICIDE
Abstract
(EN)
Disclosed are compounds of Formula I and N-oxides or salts thereof, wherein R1 is C1-C4alkyl or C3-C6cycloalkyl; R2 is H, Cl, Br or I; R3 is Cl or OR4; R4 is H or C1-C4 alkyl; R5 is H, F, Cl or CH3; and R6 is H or Cl. Also disclosed is a composition containing a compound of Formula I, and methods for controlling undesired vegetation comprising contacting the undesired vegetation or its environment with an effective amount of a compound of Formula I or a composition thereof. Also dislosed are methods for preparing a compound of Formula I.
(FR)
La présente invention concerne des composés de formule I et des N-oxydes ou des sels de ceux-ci, dans la formule, R1 représente un alkyle en C1-C4 ou un cycloalkyle en C3-C6 ; R2 est H, Cl, Br ou I ; R3 est Cl ou OR4 ; R4 est H ou alkyle en C1-C4 ; R5 est H, F, Cl ou CH3 ; et R6 est H ou Cl. La présente invention concerne en outre une composition contenant un composé de formule I, ainsi que des procédés permettant de lutter contre une végétation indésirable comprenant la mise en contact de la végétation indésirable ou de son environnement avec une quantité efficace d'un composé de formule I ou d'une composition de celui-ci. L'invention concerne également des procédés de préparation d'un composé de formule I.
