摘要:
The present invention provides a phthalic acid diamide derivative represented by the general formula (I)(wherein R1, R2 and R3 are each H, C3-C6 cycloalkyl group, group of the formula -A1-Ql or the like; X may be the same or different and are each halogen atom, nitro group, phenyl group, group of the formula -A2-R7 or the like; n is 1 to 4; Y may be same or different and are each halogen atom, cyano group, phenyl group, group of the formula -A2-R7 or the like; m is 1 to 5; Z1 and Z2 are each 0 or S), fluorine-containing aniline compound represented by the general formula (ST-I) as starting material for said phthalic acid diamide derivative(wherein Ra is halogen atom, C1-C6 alkyl group or the like and Rb, Rc and Rd is H or C2-C6 perfluoroalkyl group), and an agricultural and horticultural insecticide containing said phthaldiamide derivative, as well as to provide a method for use of said insecticide. The agricultural and horticultural insecticides of the present invention show excellent activities for controlling injurious insects.
