In this study, we identified the causative agent of stem-end rot in potatoes that were grown in Gangwon alpine areas of Korea in 2013. The disease symptoms included appearance of slightly sunken circular lesion with corky rot on the potato surface at the stem-end portion. The fungal species isolated from the infected potatoes were grown on potato dextrose agar and produced white aerial mycelia ...

Fusarium solain is the most important pathogen of huge range of plant hosts, especially potato in the word, which causes tuber rot in storage and root rot of potato plants in fields. Fifty four isolates from potato, bean, chickpea and cucurbit (melon, watermelon and cucumber) was subjected in a study through analysis of vegetative compatibility groups (VCGs) and rep-PCR DNA fingerprinting. Nit ...

Marquez-Villavicencio, M. D. P., Groves, R. L., and Charkowski, A. O. 2011. Soft rot disease severity is affected by potato physiology and Pectobacterium taxa. Plant Dis. 95:232-241. Pectobacterium species cause disease worldwide in many crop and ornamental plants, including potato. A new Pectobacterium subspecies, P. carotovorum subsp. brasiliensis was recently described in Brazil and later fo...

Brown rot, a quarantine disease caused by Ralstonia solanacearum race 3, biovar 2, comprises a major threat to the Dutch potato production chain. To avoid export losses, the Dutch government has implemented a costly control policy. However, it is unknown whether this policy is optimal from a cost-effective point of view. This thesis describes the development of a bio-economic model that can be ...

Erwinia carotovora subsp. atroseptica (Van Hall) (Eca), Erwinia carotovora subsp. carotovora (Dye) (Ecc), Erwinia chrysanthemi (Burkholder) (Ech) are pathogenic bacterias of potato crop, causing blackleg of stems in the field and soft rot of tubers in storage. During these last years, an outbreak of soft rot potatoes caused by the 3 Erwinia species has been observed in Belgium. Several methods ...

Brown rot, also known as bacterial wilt, is one of the most destructive diseases of potato. The disease has been estimated to affect about 3.75 million acres in approximately 80 countries throughout the world with global damage estimates currently over $950 million per year. The disease is known to occur in the wet tropics, sub-tropics and some temperate regions of the world. In the United Stat...

background & aim: the aim of this study was to assess the antifungal effect of the watercress extract on the growth of fusarium solani, the causal agent of potato dry rot. experimental:  this research was done in a completely randomized design with three concentrations and four replicates on potato dextrose agar (pda) culture medium. results: results of this study indicated that all conce...

This study was performed in order to determine the distance of isolation for the seed potato production from ware potato in three regions of Ardabil, Namin and Nir. The experiment was carried out in a randomized complete block design (RCBD) with five distances (100, 200, 300, 400 and 500 meters from ware potato) and three replications with Super Elite (SE) class of Agria potato cultivar from wa...

The soft rot Enterobacteriaceae (SRE) Pectobacterium and Dickeya species (formerly classified as pectinolytic Erwinia spp.) cause important diseases on potato and other arable and horticultural crops. They may affect the growing potato plant causing blackleg and are responsible for tuber soft rot in storage thereby reducing yield and quality. Efficient and cost-effective detection and identific...
