System and method of electrosterilization of animal confinement beds, by means of the synergism of pulsed electric fields and condensed electromagnetic waves applied to corresponding agricultural equipment/implements, characterized by a system of electrosterilization of animal confinement beds, through the harmonic synergism of electric fields, magnetic fields and condensed electromagnetic waves, applied to equipment (1) applied in agricultural implements and similar to electrosterilize animal confinement beds, through harmonic synergism of electric fields, magnetic fields and electromagnetic waves condensed inside the longitudinal tunnel (4) formed by at least a pair of upper electrodes (5 and 5a) interspersed by an upper UVC lamp (7) forming an upper cassette (2), aligned parallel with the lower cassette (3) formed by at least a pair of lower electrodes (6 and 6a) interspersed with a lower UVC lamp (8), together with polarizing electrodes formed by a right polarizer (10) and a left polarizer (11) of electromagnetic waves.
