<p>The present invention provides a bipyridine compound represented by formula (I), or an N-oxide, salt or metal complex of the bipyridine compound. (In formula (I), each of A1 and A3 independently represents a carbon atom, a nitrogen atom, an oxygen atom or a sulfur atom; A2 represents a carbon atom or a sulfur atom; each of R1, R2, R3 and R4 independently represents a halogeno group or the like; n1 represents the number of R1 moieties, which is an integer of 0-4; n2 represents the number of R2 moieties, which is an integer of 0-4; n3 represents the number of R3 moieties, which is an integer of 0-3; n4 represents the number of R4 moieties, which is an integer of 0-3; each of R5, R6 and R7 independently represents a C1-6 alkyl group or the like; n5 represents the number of R5 moieties, which is an integer of 0-2; n6 represents the number of R6 moieties, which is an integer of 0-2; n7 represents the number of R7 moieties, which is an integer of 0-2; and each of two broken lines independently represents a single bond or a double bond.)</p> |
