NITROGEN-CONTAINING HETEROARYL DERIVATIVES AND FUNGICIDES FOR AGRICULTURAL AND HORTICULTURAL USE

摘要

Disclosed are nitrogen-containing heteroaryl derivatives represented by formula (1), salts and N-oxides thereof, and fungicides for agricultural and horticultural use which contain at least one of these compounds as the active ingredient. In formula (1), R1 represents an optionally substituted C1-6 alkyl group; R2 represents a hydrogen atom or a group such as an optionally substituted C1-6 alkyl group; A1 and A2 represent an oxygen atom or the like; J represents an oxygen atom or the like; X represents an optionally substituted C1-6 alkyl group, a halogen atom or the like; n, which stands for the number of X's, represents an integer of 0 to 3, provided that when n is 2 or greater, X's may be either the same or different; B1 to B4 independently represent a nitrogen atom or a carbon atom, provided that all of B1 to B3 are not nitrogen atoms at the same time and all of B1 to B4 are not carbon atoms at the same time; and D represents a group represented by formula (2), formula (3) or the like [in formulae (2) and (3), Q1 represents an optionally substituted C6-10 aryl group or the like; and R7 and R8 represent a hydrogen atom, an optionally substituted C1-6 alkyl group or the like].
