Abstract:
Background and Objective: Yam (Dioscorea spp.) occupies an important place in the diet of the populations of Côte d'Ivoire. However, during storage, significant losses due to fungi are observed. The objective of this work was to identify the fungi associated with post-harvest rot of yam varieties grown in Côte d'Ivoire. Materials and Methods: To do so, a survey was conducted in ten communes of the District of Abidjan to identify, first, the difficulties encountered by traders during the storage of yams. Then, sampling was carried out in ten markets in the District of Abidjan to collect yam tubers showing characteristic symptoms of rot. From these symptoms, eight fungi were isolated. These were: Botryodiplodia sp., Penicillium sp., Aspergillus sp., Mucor sp., Fusarium sp. and Rhizopus sp. Results: Among these fungi, Botryodiplodia sp., was the most isolated with a frequency of 41.66%. Pathogenicity tests performed with these fungi showed that Penicillium was the most virulent. Two types of symptoms were observed on the tubers after inoculation. They are wet rot with brown colouration and dry rot with brown colouration. Conclusion: Isolations carried out on the collected tubers showing different types of rots showed the presence of several pathogens associated with these symptoms. At the end of the pathogenicity tests, the genus Penicillium sp. and Aspergillus sp., were the most virulent.
