AB  - Pot trials were conducted at Michael Okpara University of Agriculture Umudike, Abia State, Nigeria to investigate the performance of four plant extracts (<I>Azadirachta indica</I>, <I>Garcinia kola</I>, <I>Zingiber officinale</I> and <I>Allium sativum</I>) and three synthetic pesticides (furadan, benomyl and streptomycin sulphate) for the control of bacterial leaf spot of two varieties of <I>Solanum </I>(<I>S. gilo </I>and <I>S. torvum</I>). The experiment was laid out in a Completely Randomized Design (CRD) and replicated three times. The results showed that <I>A. indica</I> and <I>Z. officinale</I> at 5 g L<SUP>-1</SUP> were as good as the synthetic pesticides such as benomyl (0.1 g L<SUP>-1</SUP>) in reducing bacterial leaf spot disease severity of the two varieties; <I>S. gilo</I> (2.52) and <I>S. torvum </I>(3.48) in contrast with the control experiment, water (4.94-5.52). In this study, some plant extracts can serve as alternatives to the synthetic pesticides in the control of bacterial leaf spot disease of <I>Solanum</I> without any adverse effect on crop yield and yield parameters. The use of plant extracts therefore can be recommended to farmers considering their environmentally friendliness and availability.
