Abstract :

Field studies were conducted in 2011 and 2012 rainy seasons to evaluate seven genotypes/lines of tomato for fungal disease problems. Tomato seedlings raised in the nursery and later transplanted to the field were observed for fungal disease symptoms. The design of the experiment was randomized complete block design (RCBD) with four replications. The tomato plants with symptoms were taken to the laboratory for isolation and identification. The results showed that Fusarium oxysporum and Rhizopus stolonifer were the predominant fungal pathogens isolated from tomato lines. Therefore, they were considered as the most endemic fungal pathogen affecting tomato in Nsukka south eastern Nigeria.
