CHARACTERIZATION OF FUSARIUM SPECIES ASSOCIATED WITH MANGO MALFORMATION DISEASE IN SOUTHERN SENEGAL

In Senegal mango production has long existed in traditional forms, especially the south and center of country. It accounts for 60% countrys fruit production, with an estimated annual output 150,000 tons. Despite a positive balance sheet recent years, orchardsareaffected by numerous phytosanitary constraints like diseases insect pests. Among diseases, malformation is considered one most deadly tree. Since its discovery 2009 Senegal, disease continued to spread this area incursions towards northern part Few studies were dedicated that pathogen Senegalese context. This study was carried out help bring more light identity pathogen(s) causing disease. Therefore 13 isolates Fusarium obtainedfrom tissueswere characterized using morphological criteria molecular analysis.
