Conteúdo: | The effects of pre-planting solarization or fumigation with metham-sodium of sand-mulched soil on fusarium wilt of watermelon in plastic house culture were investigated at Almeria, south eastern Spain. In two trials, 2 months' solarization increased the average maximum soil temperature by c. 5oC to 44-48oC at 10 cm depth and by 4-5oC to 40-42oC at 20-30 cm. The amount of Fusarium oxysporum in the upper 15 cm of a naturally infested soil was reduced by solarization and by fumigation. During the 9 months following treatment, the F. oxysporum population stabilized at a low level in soil solarized for 2 months, but fluctuated in soil solarized for 1 month and increased in fumigated soil. The amount of wilt in watermelon sown into this soil after treatment was generally low; plants growing in solarized or fumigated soil suffered lesswilt than plants in untreated soil but the differences were not significant. In a soil artificially infested with the highly pathogenic race2 of F. oxysporum f. sp. niveum, F. oxysporum populations were greatlyreduced following solarization or fumigation, and fluctuated erratically thereafter. Solarization for 2 months completely controlled wilt inwatermelon and gave a fruit yield almost five times that of plants in untreated soil. Solarization for 1 month only slowed disease development slightly but gave a yield more than twice that in untreated soil.
