Aim of this work is to study three heat treatmentsnon-solarization, solarization and solarization with ACPC (asymmetric compound parabolic concentrator), effects on Ralstonia solanacearum population in the soil. The responses are that the used solarization with ACPC increased different temperature levels in the soil during the 4 hr in which the recorded temperatures went over 50 deg C and 40 deg C, at 0 cm and 5 cm soil depth, respectively, affecting the Ralstonia solanacearum population. The used solarization with ACPC had great effects on the microbiological population in the soil. In solarization with ACPC it has showed comparable results with decreasing in Ralstonia solanacearum population, with the advantage that it is compatible for a more sustainable agriculture practice.
