Fusarium dryrot is characterized by an internal light to dark brown or black rot (Figure 1) of the potato tuber-and it is usually dry. The rot may develop at an injury such as a bruise or cut. The pathogen penetrates the tuber, often rotting out the center. Potato tuber or seed rot is among the most important and damaging diseases ofpotatoes after harvesting, storing, and planting4, the most prevalent of which is dryrot caused by some species of Fusarium, especially Fusarium solani which is highly pathogenic5. Potatoes are particularly valued in developing countries as a rich source of vitamins C and B6, starch and essential amino acids. Fusarium solani species complex (FSSC) is a common pathogen ofpotato, causing dryrot in the Upper Egypt. Dryrot is a serious potato disease and causes significant losses in China. Research efforts on potatodryrot have been very limited as well as the attempts to characterize the pathogen in the major potato production regions of China. The dryrot disease ofpotato is caused by Fusarium species is a disastrous disease ofpotato as postharvest disease that can contribute huge losses ofpotato during storage. During current study market based survey was done in Rawalpindi and Islamabad during year 2021to estimate... Dryrotofpotato (Solanum tuberosum L.) is an important postharvest disease during storage. The decay can be caused by several different species of Fusarium spp., such as, F. sambucinum, F. coeruleum, F. oxysporum, F. avenaceum, F. culmorum. ] Fusarium dryrot is characterized by an internal light to dark brown or black rot and dryness of the potato tuber . The rot may develop at an injury such as a bruise or cut. The pathogen penetrates the tuber, often rotting out the center. The potato is the most important dicotyledonous source of human food, ranking as the fifth major food crop of the world. Fusarium-induced potatodryrot is an economically important problem ofpotatoes both in the field and in storage. B. T. Galloway, Chief of Bureau. The •. Dryrotofpotatoes. Due to fusarioi oxysporoi. Erwix f. smith. Dryrot is the most important fungal rotofpotatoes, affecting around 1% of tubers in Great Britain. It is mainly caused by a group of four Fusarium species, particularly in warm, sandy soils. Interpretive Summary: Symptoms of the disease Fusarium dryrot include a dark, tissue discoloration that can progress to form a dry, crumbly rotof the potato. The disease causes hundreds of millions of dollars of losses in tuber storage houses each year. Dryrot is the most important fungal rotofpotatoes in Great Britain. The disease affects around 1% of tubers annually. However, its true impact on the industry is often underestimated because the disease enables Erwinia species to colonise and develop into soft rots. Fusarium dryrot is a post-harvest disease ofpotato (Solanum tuberosum L.) and is of world wide significance (Hooker, 1991). Several Fusarium species cause potatodryrot. The predominant causal agents are F. solani (Mart.) ABSTRACT Dryrot disease caused by Fusarium solani is one of the most common and destructive potato diseases.This fungi causes different colored rots on potatoes.The symptoms of dryrot include mummified and wrinkled...
