Fusarium spp. (F. solani and F. oxysporum) are the important soil-borne pathogens and infects wide varietyof hosts. The effects of Trichoderma harzianum, T. asperellum, and T. virens on the wilt disease complex of tomato(Solanum lycopersicum) caused by Fusarium oxysporum f. sp. ciceri and Rhizoctonia solani were investigated undergreenhouse conditions. Tomato cultivar inoculated with F. oxysporum f. sp. ciceri and R. solani, showed greater wiltincidence, chlorosis of leaves and induced vascular discoloration in roots. Soil administration with biocontrol agentsadjusted the severity of wilt in roots, substantially (P<0.01). The disease control was highest with a combination of T.harzianum, T. asperellum, and T. virens (80-87%) followed by binary combination of Trichoderma. spp. (79%-82%),while the lowest control was done with T. viride (65%). It is concluded that T. harzianum, T. asperellum and T. viride couldcontrol pathogen attacks in tomato and it can be considered as an applicable strategy in control measures againstpathogens.
