Page/Page column 59, (2008/06/13)
PROBLEM TO BE SOLVED: To provide a herbicide excellently safe for humans and animals, having high selectivity for crops, exhibiting high herbicidal effects with a low dose and having wide applicability, persistence of the effects and excellent selectivity between crops and weeds and especially excellent performances as a paddy herbicide. SOLUTION: A haloalkylsulfonanilide derivative is represented by general formula (I) [wherein, R1 denotes a halo(1-6C)alkyl; R2 and R5 denote each an H, a (1-6C)alkyl, a (substituted) phenyl(1-6C)alkyl or the like; R3, R4, R6 and R7 denote each an H, a (1-6C)alkyl, a (3-6C)cycloalkyl, a halogen, a CN or the like; R3 and R4 may mutually be bound to form a 3- to a 7-membered ring; R6 and R7 may mutually be bound to form a 3- to a 7-membered ring; A denotes O or S; G denotes O, S or a CR8, R9 {wherein, R8 and R9 denote each H, a (1-6C)alkyl or the like}; Q denotes a (1-6C)alkyl, a (substituted) (3-6C)cycloalkyl or the like; a and b denotes each 0 or 1; and X denotes H, a halogen, a (1-6C)alkyl, a (substituted) phenyl, a (substituted) heterocyclic ring or the like]. The herbicide comprises the haloalkylsulfonanilide derivative or its salts as an active ingredient. COPYRIGHT: (C)2006,JPO&NCIPI
