First Report of Leaf Spot Caused by Alternaria tenuissima on Black Chokeberry (Aronia melanocarpa) in Korea
In July 2015, diseased leaves of black chokeberry (Aronia melanocarpa) were observed in Danyang and Gochang, Korea. The symptoms appeared as circular or irregular brown leaf spots, from which Alternaria tenuissima was isolated. The isolates were cultured on potato dextrose agar, and their morphological characteristics were observed under a light microscope. The colonies were whitish to ash colo...
متن کاملEpidemiology and Control of Strawberry Bacterial Angular Leaf Spot Disease Caused by Xanthomonas fragariae
Strawberry bacterial angular leaf spot (ALS) disease, caused by Xanthomonas fragariae has become increasingly problematic in the strawberry agro-industry. ALS causes small angular water-soaked lesions to develop on the abaxial leaf surface. Studies reported optimum temperature conditions for X. fragariae are 20°C and the pathogen suffers mortality above 32°C. However, at the nursery stage, dise...
متن کاملHeat Treatment Effects on Strawberry Plant Survival and Angular Leaf Spot, Caused by <italic>Xanthomonas fragariae</italic>, in Nursery Production
Angular leaf spot (ALS), caused by the bacterium Xanthomonas fragariae, is one of the most damaging diseases in strawberry nursery production (17). The pathogen was first reported in Minnesota in 1962 and has since been found in several U.S. states as well as strawberry-growing regions in Europe, South America, Africa, Australia, and New Zealand (12,17). The disease affects the foliage, often a...
متن کاملNiclosamide inhibits leaf blight caused by Xanthomonas oryzae in rice
Rice leaf blight, which is caused by the bacterial pathogen Xanthomonas oryzae pv. oryzae (Xoo), results in huge losses in grain yield. Here, we show that Xoo-induced rice leaf blight is effectively controlled by niclosamide, an oral antihelminthic drug and molluscicide, which also functions as an anti-tumor agent. Niclosamide directly inhibited the growth of the three Xoo strains PXO99, 10208 ...
متن کاملAspergillus leaf spot of field bindweed (Convolvulus arvensis L.) caused by Aspergillus niger in China
Leaf spot was found on field bindweed (Convolvulus arvensis L.) in Shihezi City, Xinjiang Province, China, during the summer of 2015. Pathogens were isolated from the infected leaves of field bindweed and identified as Aspergillus niger based on morphological and molecular analyses (internal transcribed spacer rDNA and β-tubulin gene). A pathogenicity test confirmed that Aspergillus niger cause...
