“…In another study, a significant reduction in dry rot between 35 and 95% was observed when using individually or in combination with thiabendazole. However, when bacillus ceruse was used individually, the inhibition was between 37 and 88% (Al-Mughrabi et al, 2013).…”

The dry rot disease of potato is caused by Fusarium species is a disastrous disease of potato as postharvest disease that can contribute huge losses of potato during storage. During current study market based survey was done in Rawalpindi and Islamabad during year 2021to estimate the disease prevalence and diseases losses during storage of different potato verities in different months. It revealed that maximum dry rot disease prevalence of potato was 1.90%, 1.86% in Rawalpindi and Islamabad respectively. Fungi isolates were isolated from diseases samples and were preserved and identified on the basis of cultural and morphological keys. The pathogenicity test confirmed the virulence of pathogenic fungal isolates. Among the cultivars, average loss of dry rot of potato within the three months; August and September, October were found in cultivar Kuroda and Lady Rosetta was 1.36% and 1.21% respectively in Rawalpindi while 1.86% and 1.48% average loss was estimated in Kuroda and Lady Rosetta respectively in Islamabad. During disease management studies in which biocontrol agent (Pseudomonas fluorescence, Bacillus subtilis and Bacillus cereus) were used during the dual culture technique and P. fluorescence was found most effective which reduced the 70% growth of fungal isolates and the maximum zone of inhibition 16mm was calculated. These preliminary postharvest disease studies will ultimately a source of information for the researchers and industrialist to develop cost effective and ecofriendly management against dry rot disease of potato during storage conditions.

“…A comprehensive review by Bojanowski et al 2013 highlighted the role of these antagonistic microbes, such as Pseudomonas, Enterobacter, Pantoea (Schisler and Slininger 1994), Trichoderma harzianum (Sadfi et al 2001), Bacillus cereus (Sadfi et al 2002), P. fluorescens (Slininger et al 2003), B. cepacia (Recep et al 2009), Glomus irregular mycorhizza (Ismail and Hijri 2012) in mitigation of potato dry rot diseases. Some bio-pesticides Bio-save 10LP and 11LP (Pseudomonas syringae) are also registered in the USA to control dry rots and silver scurf in potato (Al-Mughrabi et al 2013). After 2013, some of the bioagents found promising in managing this disease have been discussed here.…”

“…The aggressiveness of different species depends upon the storage conditions and cultivars types. The management strategy mainly includes the use of resistant cultivars, disease-free seed potato, cultural practices, bioagents, chemical treatment and storage microenvironment management (Bang 2007;Peters et al 2008a;Al-Mughrabi et al 2013;Bojanowski et al 2013;Jiang et al 2019). The current scenario demands an exhaustive screening of available cultivars and potato germplasms to identify the source of resistance and to frame a suitable breeding program.…”

Potato dry rot disease: current status, pathogenomics and management

Potato dry rot disease caused by Fusarium species is a major threat to global potato production. The soil and seed-borne diseases influence the crop stand by inhibiting the development of potato sprouts and cause severe rots in seed tubers, table and processing purpose potatoes in cold stores. The symptoms of the dry rot include sunken and wrinkled brown to black tissue patches on tubers having less dry matter and shriveled flesh. Fungal infection accompanied by toxin development in the rotten tubers raises more concern for consumer health. The widespread dry rot causing fungal species (Fusarium graminearum) is reported to have a hemibiotrophic lifestyle. A cascade of enzymes, toxins and small secreted proteins are involved in the pathogenesis of these hemibiotrophs. With the availability of the genome sequence of the most devastating species Fusarium sambucinum, it is important to identify the potential pathogenicity factors and small secreted proteins that will help in designing management strategies. Limited resistant cultivars and the emergence of fungicide-resistant strains have made it more threatening for potato cultivation and trade. Several novel fungicide molecules (Azoxystrobin, chlorothalonil and fludioxonil), are found very effective as tuber treatment chemicals. Besides, many beneficial bioagents and safer chemicals have shown antibiosis and mycoparasitism against this pathogen. Germplasm screening for dry rot resistance is important to assist the resistance breeding program for the development of resistant cultivars. This review aims to draw attention to the symptomatology, infection process, pathogenomics, the role of toxins and management approaches for potato dry rot disease, which is very much critical in designing better management strategies.

“…Nevertheless, chemical synthetic fungicides are not a long-term solution due to the ecological environment and drug resistance. Currently, some eco-friendly control measures such as the use of some organic acids and salts [ 7 ], inorganic salts [ 8 , 9 ], chitosan [ 10 ], plant essential oil [ 11 , 12 ] and biological antagonists [ 13 , 14 ] for the management of post-harvest disease in potato tubers are being explored and developed. The present review focuses on dry rot occurrence (including the causal pathogens of dry rot, the symptoms of dry rot, and its pathogenesis), mycotoxin production (non-trichothecenes and trichothecenes), and management strategies.…”

Fusarium dry rot is one of the major potato diseases during storage after harvest, which not only results in quality degradation but also causes great economic losses. The disease can be elicited by some species of Fusarium, and the pathogenic fungi of Fusarium causing potato dry rot are considerably diverse in various countries and regions. The disease caused by Fusarium spp. is associated with mycotoxins accumulation, which has phytotoxic and mycotoxic effects on humans and animals. Chemical synthetic fungicide is considered the main control measure for the Fusarium dry rot of potato; nevertheless, it is unfortunate that persistent application inevitably results in the emergency of a resistant strain and environmental contamination. A comprehensive disease control strategy includes potato cultivar selection, appropriate cultural practices (crop rotation, cultivate pattern, fertilization, and irrigation), harvesting processes and postharvest treatments (harvesting, classification, packaging, wound healing), and storage conditions (environmental disinfection, temperature, humidity and gas composition) along with the application of fungicide pre-harvest or post-harvest. Recently, emerging studies have indicated that eco-friendly strategies include physical control, chemical methods (such as the application of generally-recognised-as-safe (GRAS) compounds or chemical (elicitors) and biological control have been introduced to combat the Fusarium dry rot of potato.
