The present invention relates to an aromatic diamide derivative represented by the general formula (I): 

Aromatic diamide derivatives, chemicals for agricultural or horticultural use and usage thereof

The present invention provides a process for producing 2-halobenzoic acids of the general formula (I), characterized by reacting a benzoic acid of formula (II) with a halogenating agent in the presence of Pd catalyst: (wherein A is &#x2014;OH, &#x2014;OM (M is alkali metal), &#x2014;N(R)R(Rand Rare each H, C&#x2013;Calkyl, optionally substituted phenyl, or the like); R is H, C&#x2013;Calkyl, C&#x2013;Calkylcarbonyl, carboxyl, C&#x2013;Calkoxycarbonyl, optionally substituted phenylcarbonyl, or the like; n is 0 to 4; X is Cl, Br or I, or alternatively (R)n may be present on benzene-constituting carbon atoms adjacent to each other and form a C&#x2013;Calkylene- or C&#x2013;Calkenylene-fused ring).
