Abstract
Compounds represented by general formula (I), herbicides or selective herbicides for paddy field containing the compounds as active ingredients, method of controlling growth of undesirable plants by applying the herbicides on places where control is desired. (see clain 1) in which A represents a -S(O)nR1 in which n is 0 or 2 and R1 represents a (substituted) lower alkyl; a cycloalkyl; a (substituted) benzyl; a (substituted) phenyl; or a -OR2 in which R2 represents a (substituted) phenyl; B represents a halogen, a nitro, a lower alkyl, or a lower alkylsulfonyl; D represents a hydrogen, a lower alkyl, a lower alkoxy, a lower alkoxymethyl, or a lower alkoxycarbonyl; E represents a halogen, a (substituted) lower alkoxy, a lower alkylthio, a (substituted) lower alkylsulfonyl, or a lower alkylsulfonyloxy. The herbicides of the present invention can prevent a wide variety of noxious weeds and further selectively prevent weeds on paddy field with considerably reduced phytotoxicities on rice plant.
