Chocolate spot disease caused by Botrytis fabae and Botrytis cinerea, is one of the most important diseases on faba bean in Egypt. Botrytis fabae, Botrytis cinerea, Alternaria alternata and Stemphylium botryosum were isolated from infected leaves of two faba bean cultivars (Giza 461 and Giza 3 cvs.) throughout two growing seasons (2004-2005 and 2005-2006). These fungi were varied between cultivars and years, also, were isolated more frequently from Giza 3 cultivar compared with Giza 461 cultivar in both seasons especially in the second season. The sensitivity of B.fabae and B.cinerea to five fungicides (Topsin-M, Rovral, Ferrocopper, Dithane M-45 and Kocide 101) were studied under laboratory conditions. The results showed that B.fabae was more sensitive to these fungicides than B.cinerea, where EC50 values were 1.0 and 1.7, 1.3 and 1.8, 2.1 and 2.9, 5.8 and 9.0 and 66.0 and 96 ug a.i/ ml, respectively. The field trails showed that Topsin-M and Rovral were the most effective fungicides in reducing disease incidence, severity and finally increased yield, followed by Ferrocopper and Dithane M-45 and the least effective were Kocide 101 and bioagent (Plant-Guard). Efficiency of these compounds increased with increasing the rate of application. These fungicides gave good control of chocolate spot disease and improved plant growth and increased grain yield. Also, the results showed that Giza 461 cultivar was more resistant to this disease than Giza 3 cultivar.
