We present a search for the decay X(3872) → π+π-π0 in the (772 ±11) ×106 Y(4S)→B$$\overline{B}$$ data sample collected at the Belle detector, where the X(3872) is produced in B± → K±X(3872) and B0→K$$^{0}_{S}$$X(3872) decays. We do not observe a signal, and set 90% credible upper limits for two different models of the decay processes: if the decay products are distributed uniformly in phase space, $$\mathscr{B}$$(X(3872) → π+π-π0)<1.3%, and if M(π+π-) is concentrated near the mass of the D0$$\overline{D}$$0 pair in the process X(3872) → D0$$\overline{D}$$*0 + c.c. → D0$$\overline{D}$$0 π0 → π+π-π0, $$\mathscr{B}$$(X(3872) → π+π-π0)<1.2×10-3.
