| Abstract | ||||
| Field experiments were conducted in a private farm at Abia El-Hamra Village, El-Delengat district, El-Beherah Governorate to evaluate the efficacy of five chemical fungicides and three bioagents on root rot diseases caused by Fusarium solani and Rhizoctonia solani in faba bean (vicia faba) (cv. Sakha 716) under field conditions during the two consecutive growing seasons (2018-2019 and 2019-2020). The tested fungicides were carbendazim (Nasr Zim 50% W.P), thiram (No-Blight 50% WP), carboxin+ thiram (Tendro 40% FS), tolclofos-methyl + thiram (Rizolex-T 50% WP) and fludioxonil +mefenoxam (Maxim XL 3.5%). The used bioagents were: Bacillus megaterium (Bio- Arc 6% WP), Trichoderma album (Bio-Zeid 2.5% WP) and Trichoderma harzianum {(Plant guard), (30 million spores cm-3,}. All treatments were applied at three rates of applications 1, 2 and 3gm or ml formulated material Kg-1 of seeds. The results clearly indicated that chemical fungicides were more effective than biofungicides. The higher rates were the most effective particularly, tolclofos-methyl + thiram, carboxin+ thiram and fludioxonil +mefenoxam. Theyignificantly (P= 0.05) reduced the pre- and post-emergence rotted roots, increased the survival plants and subsequently increased yield and some agronomic traits in comparison with the untreated control. | ||||
