Abstract:
In 2005, a crown and root rot, a yellowing and a death of muskmelon plants were observed in some tunisian melon-growing regions. Isolation was made from diseased tissues. Twelve isolates of Fusarium solani were identified and used to inoculate melon-seedlings by the root dip method for 1 min. These 12 isolates caused typical symptoms of Fusarium crown rot and their pathogenicity indicated that they are identical to Fusarium solani f. sp. cucurbitae. Disease severity on melon-plants, cv. “Ananas d’Amérique”, was estimated by indexes of the leaf damage and crown rot. Analysis of variance revealed significant difference between control and inoculated plants. A significant difference was also observed between some F. solani f. sp. cucurbitae isolates in causing leaf damage and crown rot and a negative effect was observed mainly on plant fresh weight revealing impact of this pathogen on muskmelon growth.
