In this work the role of magnetic Landau quantization in the dynamics and spectrum of Diced Lattice charge carriers is studied in terms of the associated pseudospin 1 Green function. The equations of motion for the 9 matrix elements of this Green function are formulated in position/frequency representation and are solved explicitly in terms of a closed form integral representation involving only elementary functions. The latter is subsequently expanded in a Laguerre eigenfunction series whose frequency poles identify the discretized energy spectrum for the Landau quantized Diced Lattice as ε_(n) = ±√(2(2n + 1)α²eB) (α√(2) is the characteristic speed for the Diced Lattice), which differs significantly from the non-relativistic linear dependence of ε_(n) on B, and is similar to the corresponding √(B)-dependence of other Dirac materials (Graphene, Group VI Dichalcogenides).
