Abstract

One of the diseases of tomato, an important vegetable crop, that is known everywhere in every part of the world is Bacterial speck (Pseudomonas syringae pvtomato. Chemical control has not been very effective and unsafe for the environment hence, the need for alternative methods of controlling the disease. This study accessed the effect of plant extracts on the frequency and ruthlessness of bacterial speck of tomato on two tomato cultivars (Roma VF and Gboko). Experimental construction and design was in form of a Randomized Complete Block Design (RCBD) having three (3) replicates. Plant extracts from Moring a oliefera, Azadirachta indica, Chromolaena odorata at 12.5% w/v and 25% w/v concentrations were applied. Data were subjected to Analysis of Variance (ANOVA) and means separated by the Duncan's Multiple Range Test (p &
