Influence ofCropping Pattern Systems on Incidenceof Scab and SeptoriaLeaf Spot Disease ofCowpea (Vigna unguiculata)

Aims: Scab caused by Sphaceloma sp and Septoria leaf spot caused by Septoria vignae were evaluated on one variety (Ife Brown) of cowpea: in this study. Ife Brown is highly susceptible to scab and moderately susceptible to Septoria leaf spot. Cowpea ( Vignia unguiculataL.Walp) was planted simultaneously with maize (intercrop ) and sorghum (intercrop).The scientific importance of intercropping pattern in this study was to develop an information based system on how crop pattern can influence disease incidence and severity and thus improve crop yield within an agro ecological zo ne Study Design:The field layout was factorial concept in Randomized Complete Block Design (RBCD) with four replications Place and Duration of Study:The two cereals used for this study were, maize variety
