Abstract Potato (Solanum tuberosum L.) is one of the most important crops in the world. Potato ranks fourth position in the world after wheat, rice and maize as non-cereal food crop. Potato tubers constitute a highly nutritions food. In Egypt, it is considered one of the most important vegetable crops consumption, as well as one of the cash crop in export. The cultivated area of potato in Egypt more than 450.000 feddan in season, yielded more than 5 million tons with average yield about 11.5 ton/feddan. Many diseases caused by fungi and pseudofungi are important and require a variety of management practices to reduce them to tolerable economic level. Pathogens attack potato plants during different growth stages, as well as after harvest during storage and marketing. These diseases cause economic loss and decrease in shelf life. In this regard, Fusarium dry rot is one of the most important post-harvest diseases of potato occurring worldwide. Its infects tubers in storage and tuber pieces in fields after planting. The disease develops fairly rapidly at temperatures above 10°C, meanwhile most fungal infections occur as the fungus enters through harvest wounds. Because importance of this disease, the present study where done to investigate the isolation of the causal organism(s) from diseased tubers, identification and frequency, pathogenicity tests, storage treatments, studies in infection during storage in tuber tissues, control treatments using, i.e. fungicides, biological control agents and plant extracts. |
