Field experiments were performed in a private farm atKhaled Ibn El-WaleedVillage, Badr Center, El-Behera Governorate to evaluate the efficacy of four chemical fungicides and three biofungicides against damping-off and root rot diseases in common bean caused by Fusarium solani, Rhizoctonia solani, Pythium ultimum and Sclerotium rolfsii under field conditions during the two consecutive growing seasons (2018 and 2019). The four fungicides were { Tendro 40% FS (carboxin+thiram), Maxim XL 3.5% FS (fludioxonil+metalaxyl-M), Hattric 6% FS (tebuconazole) and Rizolex-T 50% WP (tolclofos-methyl+thiram) at two rates (1.75 and 3.50 cm³, 0.50 and 1.00 cm³, 0.50 and 1.00 cm³ and 1.50 and 3.00 gm kg^-1 seeds, respectively). Three biofungicides} Rhizo-N [(30 million cell gm^-1) (Bacillus subtilis)], Biocontrol T 34 12% WP (Trichoderma asperellum) and Plant Guard [ (30 million cell ml^-1) (Trichoderma harzianum)] were used at two rates (2.00 and 4.00 gm, 1.00 and 2.00 gm and 1.25 and 2.50 cm³ kg^-1 seeds, respectively)}. The results clearly indicated that, chemical fungicides were more effective than the biofungicides, and all the tested compound particularly Rizolex-T 50% WP, Tendro 40% FS and Maxim XL 3.5% FS were significantly reduced pre- and post-emergence damping-off, rotted roots, increased survival plants and subsequently increase biological, seed and straw yields in comparison with the untreated control. All chemical fungicides particularly Hattric 6% FS reduced nodules number per plant. In contrast, the tested biofungicides increased nodules number per plant. In connection with the tested rates, all the tested compounds gave better results at their high application rates but accompanied with reduced the nodules number in case of chemical fungicides and increased nodules number in case of biofungicides.
