Abstract
Two hundred and fifty nine fungal pathogens were isolated from the diseased tomato by root-rots which collected from six governorates; Baheira, Giza, Ismailiya, Qalubiya, Qena and Sharkiya, roots during 2012 and 2013 seasons. Alternaria solani, Fuarium oxysporum and Rhizoctoina solani were the most frequent fungal that isolated from infected tomato root. Twenty fungal isolates were selected according to isolation frequency and geographic distributions. Their virulence and pathogenicity was individuality tested against healthy and informal tomato root cultivar (GF12).Pathogenicity experiment showed the aggressive fungal pathogens either for wounded tomato plants or unwounded ones are Alternaria solani No.1, Fuarium oxysporum No.1 and Rhizoctoina solani. All tested bioagents were decreased the linear growth of A. solani. The growth reduction percentages ranged between 85.2 and 46.7%. R. solani was more sensitive to twenty tested bioagents since its linear growth declined clearly compared to other pathogens. The over growth phenomena of Trichoderma bioagent was more clear in R. solani than other tested fungal pathogens.Antagonistic studies under greenhouse conditions concluded the potency of T. harzianum Tz1, T. koningii Tk1, T. longbactrium Tl1 and T. viride Td1 against of tomato root rot pathogens. Different strategies are applied to enhance the activity of these promising bioagents in an individual upcoming study
