Relativistically covariant form of equation of motion for arbitrarily shaped dust particle (neutral in charge) under the action of electromagnetic radiation is derived -- emission, scattering and absorption of radiation is considered. The result is presented in the form of optical quantities used in optics of dust particles. The obtained equation of motion represents a generalization of the Poynting-Robertson (P-R) effect, which is standardly used in orbital evolution of dust particles in astrophysics. Simultaneous action of electromagnetic radiation and gravitational fields of the central body -- star -- on the motion of the particle is discussed.
