Bacterial wilt caused by Ralstonia solanacearum constitutes one of the most difficult diseases to control. The use of disinfested substrates is important for the production of disease-free seedlings and prevents the dissemination of this pathogen. An equipment was developed at Embrapa Environment, in Brazil, aiming to disinfest substrates with solar radiation. The solar collector is efficient to control several fungal plant pathogens, including species of Fusarium, Pythium, Rhizoctonia, Sclerotium, Sclerotinia, Phytophthora, as well as nematodes such as Meloydogyne (1, 2), after the treatment of the substrate during only one sunny day. The purpose of this work was to determine the efficacy of the solar collector for the control of the bacterial wilt caused by R. solanacearum.2005
