Stem rot disease was found in garlic (Allium sativum L.) cultivated from 2008 to 2010 in the vegetable gardens of some farmers in Geumsan-myon, Jinju City, Gyeongnam province in Korea. The initial symptoms of the disease were typical water-soaked spots, which progressed to rotting, wilting, blighting, and eventually death. White mycelial mats had spread over the lesions near the soil line, and ...

Rotten sweet potato root tuber samples were collected from a barn and experimental field of the CSIR - Plant Genetic Resources Research Institute (PGRRI), Bunso. Isolation identification fungi associated with carried out at Pathology Laboratory same institute. In all, six fungal species belonging to four genera, namely Fusarium solani, Sclerotium rolfsii, Lasiodiplodia theobromae, Aspergillus o...

Rhizopus soft rot caused by Rhizopus stolonifer occurred on pears (Pyrus serotina) in the Jinju City Agricultural Products Wholesale Market in Korea from 2004 to 2005. The infection usually started from wounds due to cracking at harvest time. The lesions started as water-soaked, rapidly softened, then gradually expanded. The mycelia grew vigorously on the surface of the fruits and formed stolon...

The aim of this study was to assess the potential bacterial antagonists to control Macrophomina phaseolina root-rot of safflower by using screening methods. In total, 38 fluorescent pseudomonads isolated from rhizosphere soil of healthy safflower plants were collected from major safflower growing areas, 13 were initially selected based on dual culture technique on potato dextrose agar media. Fu...

potato (solanum tuberosum l.) an agro-economically important food crop in the world, is sensitive to many fungal pathogens including rhizoctonia solani (ag-3), the causal agent of stem and root rot diseases. chitinase and glucanase are cell wall degrading enzymes which have been shown to have high antifungal activity against a wide range of phytopathogenic fungi. in the present study, plasmid p...

The current bacterial wilt infestation level in the potato fields in the Peruvian Andes was investigated by collecting stem samples from wilted plants and detecting Ralstonia solanacearum. In total 39 farmers' fields located in the central and northern Peru between the altitudes 2111 and 3742 m above sea level were sampled. R. solanacearum was detected in 19 fields, and in 153 out of the 358 sa...

The necrotrophic fungus Macrophomina phaseolina is an important pathogen of many crops, such as strawberry, maize, sorghum, potato, soybean, chickpea, and pigeon pea, causes multiple diseases throughout the world. microsclerotia, which are source primary inoculum, play role in survival spread M. phaseolina, well disease initiation development. South Asia has unique characteristics relative to c...

Phylogeographic studies inform about routes of pathogen dissemination and are instrumental for improving import/export controls. Genomes of 17 isolates of the bacterial wilt and potato brown rot pathogen Ralstonia solanacearum race 3 biovar 2 (R3bv2), a Select Agent in the United States, were thus analyzed to get insight into the phylogeography of this pathogen. Thirteen of fourteen isolates fr...

Soft rot Enterobacteria in the genera Pectobacterium and Dickeya cause rotting of many crop plants. A new Dickeya isolate has been suggested to form a separate species, given the name Dickeya solani. This bacterium is spreading fast and replacing the closely related, but less virulent, potato pathogens. The genome of D. solani isolate D s0432-1 shows highest similarity at the nucleotide level a...

Abstract Potato rot nematode Ditylenchus destructor is one of the most damaging pests in potato-producing regions and causes severe yield losses worldwide. However, D. has been rarely reported potato crops China. We collected 542 samples from 17 Chinese provinces during 2016–2020 for detection using species-specific primers universal targeting ribosomal internal transcribed spacer (ITS) or 28S ...
