Umudike, to assess the efficacy of leaf extracts of Gmelina arborea, Chromoleana odorata and Anacardium occidentale in the control of anthracnose disease of cowpeas induced by Collectotrichum lindermuthianum and to assess the yield performance of the crop. The study was designed to evaluate the effects of the different plant extracts on the disease development, growth and yield performance of cowpea inoculated with anthracnose pathogen, with a view to identifying the most effective extract that can be used in the control of the Original Research Article
