Abstract:

Experiment was conducted in microbiology laboratory of School of Science and Science Technology, Abubakar Tafawa Balewa University, Bauchi, in 2007. The objective of the study was to determine the antifungal effect of different concentrations of some selected plant extracts (Neem seed, Moringa seed, Garlic bulb and Emulsified neem seed oil each with five concentrations of 10, 20, 30, 40 and 50g/0.25L of water and 1:1, 1:5, 1:15 and 1:20 mother extract: water for emulsified neem seed oil) on tomato and a control (untreated tomato) constituted the treatment in this study. The treatments were laid in a Completely Randomized Design (CRD) with three replications. The results obtained showed significant difference (P<0.01) on radial mycelia growth and weight loss of tomato when the aqueous plant extracts where used. Garlic bulb, emulsified neem seed oil and aqueous moringa seed extracts exhibited the highest control of the pathogen than aqueous neem extract. Also from the result obtained, it is evident that the plant extracts possessed antifungal properties which if fully exploited could be used in integrated pest management and post-harvest treatment for tomato before storage and on transit  as control measures for Aspergillus flavus .
