英语. Various approaches have been followed worldwide to improve solarization, particularly in less favourable climatic regions. In the present study an experiment was carried out, under greenhouse conditions, using solarization combined with sulphur for controlling fusarium wilt of tomato, in a soil with previous history of this disease. The population of Fusarium oxysporum was drastically reduced in the soil essentially as a result of solarization combined with sulphur. Fusarium wilt incidence on tomato plants (cv. Fandango) has been also significantly reduced. Additional effects of treatments on some chemical and biological properties of soil and weed control are also referred

O presento trabalho envolveu o estudo do efeito combinado da solarizacao com a aplicacao do enxofre no controlo da fusariose vascular do tomateiro cultivado em estufa. Os tratamentos efectuados resultaram na reducao drastica das populacoes de Fusarium oxysporum existentes no solo, em particular nas modalidades solarizadas e com aplicacao de enxofre. Registou-se igualmente diminuicao significativa da incidencia de fusariose vascular em plantas de tomateiro (cv. Fandango). Observaram-se efeitos interessantes no controlo de infestantes e em algumas caracteristicas quimicas e biologicas do solo
