Effects Of Botanical Extracts And A Synthetic Fungicide On Severity Of Cercospora Leaf Spot (Cercospora Sesame Zimm) On Sesame (Sesamum Indicum L.) Yield Attributes Under Screen House Condition In Ardo-Kola, Taraba

Screen house trials consisting five plant extracts including a synthetic fungicide (Azadirachta indica, Jatropha curcas Linn., Alium sativum, Ocimum gratissimum, Chromolaena odorata and Benlate ) were tested at the Taraba State University(TSU) Research Farm centre (Ardokoa: Latitude 08 0 53′N and Longitude 11 0 19′E) in a completely randomized design arrangement.
