Characterization of Alternaria alternata isolates causing brown spot of potatoes in South Africa
Alternaria alternata (Fr.) Keissler is now widely recognized as the causal agent of brown spot and black pit of potatoes. Brown spot is a foliar disease with potential to cause 30% yield loss and postharvest losses of up to 10%. Losses are mainly due to premature defoliation. In this study, …

The use of hot water treatment by small holders for the control of alternaria alternata, the cause of black mould disease of tomato
… income to farmers unfortunately diseases such as Alternaria alternata greatly increase food losses by an approximately 20-30% and methods of using synthetic chemical compounds can be costly and dangerous if applied by an unskilled operator and are often not available at the time when required. As …

Innate Immune Responses in the Alternaria-Dendritic Cell Interaction
Exposure to spores and hyphae of Alternaria alternata, an airborne ubiquitous fungus, is clinically associated with allergic airway disorders including allergic rhinitis, asthma, and chronic rhinosinusitis. Dendritic cells are known as the type of antigen presenting cells most often associated with …

The Effects of Agrochemicals on Litter Fungi
… of the leaf litter mycoflora was also altered: Alternaria alternata and Ulocladium botrytis showed increased incidence from fungicide-treated leaves, although Epicoccum purpurascens and Fusarium spp. were reduced. U. botrytis was recorded as the major component of VERDASAN-treated leaf litter. …

Analysis of the Allergenic Potential of the Ubiquitous Airborne Fungus Alternaria Using Bioinformatics
… airborne fungi one of the most common is <i>Alternaria alternata</i>. From a clinical perspective Alternaria has long been associated with IgE-mediated, histamine-dependent mold allergy, allergic rhinitis, chronic rhinosinusitis (CRS) and asthma. Recently it has been proven that an abnormal …

The Role of Alternaria and its Major Allergen, Alt a 1, in the Pathogenesis of Allergic Airway Disorders
… exposure to the ubiqutious airborne fungus, Alternaria alternata, has long been implicated in the development and exacerbation of human allergy and asthma. Alt a 1 was identified previously by several groups as the major allergen secreted by A. alternata, due to its IgE-specific reactivity …
