“…Similarly, cultivar maturity has been suggested to be involved in susceptibility to black dot (Andrivon et al, 1998), but this was not confirmed here. Instead, other genetic characteristics may be more important in determining cultivar susceptibility to black dot, and recent studies suggest that resistance may include several mechanisms (Massana‐Codina et al, 2020). Taken together, the results presented here contribute to a better understanding of the epidemiology of black dot and silver scurf and can help reduce the risk of both diseases.…”

Black dot and silver scurf are potato blemish diseases whose economic impact has increased in recent years. Because their symptomatology on tubers is visually similar, disease assessment does not usually differentiate between the two pathogens, which share the same ecological niche. The epidemiology of black dot has been extensively studied, especially in the UK, but the factors that influence silver scurf have been less investigated. In this study, the influence of cultivar, source of inoculum, and environmental conditions on both diseases was studied in field trials over a three-year period (2016-2018) in Switzerland. Planting minitubers did not prevent either disease in daughter tubers, indicating the contribution of soil as an inoculum reservoir. An arbitrary threshold of Colletotrichum coccodes soil inoculum could be set to discriminate between low and high disease risk. For the first time, Helminthosporium solani DNA was detected in stolons, and infections appeared earlier in stolons than in tubers. H. solani stolon and tuber infections usually appeared later in the season than those of C. coccodes. Black dot severity correlated positively with precipitation, while silver scurf severity correlated positively with temperature. Table potato cultivars commonly grown in Switzerland exhibited significant differences in susceptibility to both diseases, and cultivars with low susceptibility to both silver scurf and black dot were identified. These results gave new insights into understanding the factors driving the epidemiology of potato blemish diseases and may contribute to building a risk assessment scheme to manage both diseases simultaneously.

“…Consequently, it forestalls the translocation of nutrients and water, culminating in wilt, collapse and complete deadening of the plant and its decay [21,22]. The ubiquitous plant pathogenic fungus of Colletotrichum coccodes is responsible for the blemish disease of potatoes called black dot [23].…”

Solanum Tuberosum - A Promising Crop for Starvation Problem

View full text Add to dashboard Cite

Solanum tuberosum (Potato) is one of the essential economic crops with the potential to reduce hunger due to its high yield per unit area of land compared with many economic crops. However, its yield losses due to pest and disease attacks could be as high as 100%, depending on its tolerance level and pest and disease. Over the years, several disease management strategies have been researched, ranging from synthetic pesticides to the formulation of biopesticides as disease control measures. Moreso, recent breakthroughs in genetic engineering have simplified plant disease management strategies by developing techniques for conferring resistance on plants. Potato is a vital food crop worldwide, and with the struggle to suppress world food insecurity, effective disease management strategies must be employed for high production of quality and quantity potato, enough to feed the ever-increasing world population. Therefore, attention must be given to how disease-free potatoes can be produced to meet the unending demand for food by the continually increasing world population.

“…GC-MS methods have proven very effective in comparing metabolic footprints, aiding in biomarker discovery of pathogenicity. , MS-based studies of several Candida strains (the most common fungal pathogen) have provided a global comprehension of the metabolites that play a role in antifungal treatment resistance . These studies show that the secretion of fatty acids impairing the host’s response, immunosuppression occurring via propanoic acid, and colonization taking place via the involvement of a pyrazine derivative all contribute to antifungal treatment resistance. ,, Plant pathogen response usually involves metabolites, which can serve as physical barriers or signaling molecules . Resistance to plant pathogens has been studied using different model organisms.…”
