Abstract : The study aimed to evaluate the efficacy of leaf extract of Boswellia dalzaelii (hutch), prosopis africana (itto) and vachellia nilotica (l), in control of maize seed rot caused by fusarium verticillioides. Phytochemical screening of the plant extract was evaluated for the presence of secondary metabolite, the result revealed the presence of alkaloids, flavonoids, -glycosides, saponins, tannins, Phyto phenol, and terpenes at various degrees of concentration, which are likely the active compound of antimicrobial activities. The effects of leaf extract on the inhibition of spore germination and suppression of mycelial growth were evaluated on the PDA medium amended with extracts. The extracts showed varying degrees of efficacy against the pathogen. The results revealed lower inhibition at a lower concentration of 31.25mg/ml (31.27) and gradually decreased at a maximum concentration of 500mg/ml (11.78). Inhibition and suppression increased with increasing concentration of plant extracts on test organisms (tables 1 and 2. Similarly, the study also revealed that Mycelial growth was significantly (P ≤ 0.05) reduced with increased concentration of all the extracts. However, extracts of Boswellia dalzielii, Prosopis africana, and Vechelia nilotica show a significant difference (P ≤ 0.05) at a concentration of 31.25mg/ml, 60.5mg/ml, 125mg/ml, 250mg/ml and 500mg/ml.
