The invention relates to compounds represented by formula I (CF DRAWING IN BOPI) wherein R1 and R2 each independently represent a hydrogen atom or an alkyl, alkenyl, alkynyl, alkadienyl, haloalkyl, aryl, heteroaryl, cycloalkyl, bicycloalkyl group. or optionally substituted heterocyclyl, or R1 and R2 together with the intervening nitrogen atom form an optionally substituted heterocycle; R3, R4 and R5 each independently represent a fluorine atom or a chlorine atom, provided that at least one of R3, R4 and R5 is a chlorine atom; and X represents a halogen atom. These compounds are useful as fungicides, especially against rice blight disease. Field of application: phytosanitary products. |
