Y is an aryl group which may be substituted by Z;
Z is halogen, alkyl, haloalkyl, alkoxy, haloalkoxy, cyano, amino, alkoxycarbonylamino or nitro;
R 2 is a hydrogen atom, alkyl, alkylcarbonyl or alkylcarbonylalkyl; or
R 1 and R 2 may form, together with the adjacent nitrogen atom, a cyclic structure which may be substituted by Z, and the cyclic structure may further contain one hetero atom selected from a nitrogen atom which may be substituted by alkyl, an oxygen atom and a sulfur atom;
R 3 is a hydrogen atom, halogen, alkyl, haloalkyl, alkylcarbonyl, alkoxycarbonyl, alkoxy, amino, monoalkylamino, dialkylamino, cyano or nitro;
R 4 is halogen, alkyl, haloalkyl, alkenyl, alkynyl which may be substituted by R 8 , alkoxy, haloalkoxy, alkylcarbonyl, alkoxycarbonyl, alkylthio, haloalkylthio, alkylsulfinyl, haloalkylsulfinyl, alkylsulfonyl, haloalkylsulfonyl, amino, monoalkylamino, dialkylamino, pentafluorosulfanyl, cyano, nitro, phenoxy which may be substituted by R 9 , phenyl which may substituted by R 9 , or a pyridyl or thienyl group which may be substituted by R 9 ;
R 8 is hydrogen, alkyl, halogen, alkoxy, alkylcarbonyl, alkoxycarbonyl, amino, monoalkylamino, dialkylamino, trialkylsilyl or Y;
R 9 is halogen, alkyl, haloalkyl, alkenyl, alkynyl which may be substituted by R 8 , alkoxy, haloalkoxy, alkylcarbonyl, alkoxycarbonyl, alkylthio, haloalkylthio, alkylsulfinyl, haloalkylsulfinyl, alkylsulfonyl, haloalkylsulfonyl, amino, monoalkylamino, dialkylamino, pentafluorosulfanyl, cyano or nitro; and
p is an integer of from 0 to 4.

2. The compound or its salt according to claim 1 , wherein R 1 is a hydrogen atom, alkyl, alkenyl, alkynyl, haloalkyl, alkoxyalkyl, dialkylaminoalkyl, di alkylamino, alkylthioalkyl, cyanoalkyl, alkylcarbonylalkyl, Y or alkyl substituted by Y.
