125 The object of the present invention is to provide a novel pyrazole derivative which shows high selectivity to corn, wheat and barley and which is capable of controlling gramineous weeds and broad-leaved weeds together at a low dosage. The pyrazole derivative of the present invention to achieve the above object is the compound of the general formula (I), <IMG> (I) ¢wherein R1 is a C1-C6 alkyl group, each of R2, R3, R4 and R5 is independently hydrogen or a C1-C4 alkyl group, R6 is a C1-C4 alkyl group, R7 is hydrogen or a C1-C4 alkyl group, X1 is a C1-C4 alkyl group or a halogen atom, n is an integer of 1 to 3, p1 is an integer of 0 to 2, and Q1 is hydrogen, -SO2-R8 or <IMG> in which R8 is a C1-C6 alkyl group, Y is hydrogen, a C1-C4 alkyl group or a halogen atom, and m1 is an integer of 1 to 3.!
