Provided is a novel pesticide, particularly a fungicide and a nematicide. An alkynyl pyridine-substituted amide compound represented by formula (I), its N-oxide or a salt thereof, and a pesticide containing it. [In the formula, G1 is a structure represented by G1-1a, G1-3a, G1-27a, etc.; X1 is a halogen atom, difluoromethyl, trifluoromethyl, etc.; Y1 is a halogen atom, etc.; Y2, Y3, R4 and R5 independently represent a hydrogen atom, etc.; R1 is a hydrogen atom, a halogen atom, methyl, methoxy, etc.; R2 is a hydrogen atom, a halogen atom, etc., or R1 and R2 together form an alkylene chain thereby to form a cyclopropyl group together with the carbon atom to which R1 and R2 are bonded, or R1 and R2 together form C1-C2 alkylidene or C1-C2 haloalkylidene; R3 is a hydrogen atom, methyl, etc.; and R6 is C1-C4 alkyl, C3-C6 cycloalkyl, C1-C4 alkoxy(C1-C4)alkyl, etc.]
