An object of the present invention is to provide an industrially easily available hatching factor on Globodera pallida larvae, a control agent and a control method using the same. The Globodera pallida control agent of the present invention contains, as an active ingredient, at least one selected from a compound of formula (I) below, a stereoisomer thereof, and a salt thereof [wherein Ar represents a substituted or unsubstituted phenyl group or the like; R.sup.1 each independently represents a group such as a substituted or unsubstituted C1 to 6 alkyl group and a substituted or unsubstituted C2 to 6 alkenyl group; R.sup.2 represents a hydrogen atom or a substituted or unsubstituted C1 to 6 alkyl group; the partial structure YX represents a group represented by *N(Rb)C(?X.sup.1)**; X.sup.1 each independently represents an oxygen atom or a sulfur atom; Rb represents hydrogen atom or the like; where * indicates a binding position to the carbon atom having two R1, and ** indicates a binding position to Z; and Z represents a substituted or unsubstituted methylene group, or a substituted or unsubstituted dimethylene group.]
