ABSTRACT Cowpea is the main food legume in tropical Africa. Its production plays an important role against food insecurity, malnutrition and poverty because it is a great source of protein and provides cash in income to producers. However, like and all other crops, its production is confronted with numerous abiotic and especially biotic constraints, including parasitic fungi, the most important of which are seeds and foliar. The objective of study was to make an inventory of leaf and seed parasitic fungi of cowpea at the Saria research station. In total, seven (7) varieties were studied. To achieve this, we first carried out a sanitary test of the various seeds. Symptomatic leaves were then taken from the seed production plot of the Saria research station for laboratory analyzes. The isolation and purification of the fungal strains were performed on Potato Dextrose Agar medium while their identification was done through macroscopic and microscopic phenotypical characterization using an identification keys. Isolation of the pathogen was performed from seeds and symptomatic leaves. A total of six (6) isolates were identified as Fusarium sp., Macrophomina sp., Rhizopus sp., Phoma sp., Fusarium avenaceum and Fusarium decemcellulare from leaves including Fusarium sp. is the predominant species while five isolates have been identified as Aspergillus flavus, Aspergillus niger, Phoma sp., Macrophomina sp. and Fusarium sp. from seeds of which Aspergillus flavus is the predominant species. These results reveal that the seeds and symptomatic leaves of cowpea harbor a diversity of fungal species. |
