Abstract: The In vitro fungitoxic potential of Tagetes erectus L. was scrutinized against Ascochyta rabiei, the causal agent of chickpea blight disease. The pathogen was exposed to various concentrations (1, 2, 3 and 4% w/v) of aqueous and methanol extracts of flower and shoot of T. erectus using food poisoning technique. All the employed concentrations of both flower and shoot extracts significantly suppressed the growth of target fungal pathogen. There was 4-35% and 55-73% reduction in colony diameter of A. rabiei due to different concentrations of aqueous flower and shoot extracts of T. erectus and 12-50% and 4-42% due to different concentrations of methanolic flower and shoot extracts of T. erectus, respectively.
