The endophyte Guignardia mangiferae is closely related to G. citricarpa, the causal agent of citrus black spot; for many years these species had been confused with each other. The development of molecular analytical methods has allowed differentiation of the pathogen G. citricarpa from the endophyte G. mangiferae, but the physiological traits associated with pathogenicity were not described. We...

numerous date palm orchards in south kerman, iran were investigated during 2001-2003. symptoms of leaf die-back appeared as light brown stripes which began at leaf tips and extended to leaf ends. infected tissues were surface sterilized with 0.05% sodium hypochlorite and, plated on pda medium. isolated fungi were purified using hyphal tip method. on pda medium, fungal colony was fluffy, first c...

Keratinophilic fungi include a variety of filamentous fungi mainly comprising hyphomycetes and several other taxonomic groups. Hyphomycetes include dermatophytes and a great variety of nondermatophytic filamentous fungi. Most of the latter occur as saprophytes in soil, and some are plant pathogens. Chrysosporium species are the commonest nondermatophytic filamentous fungi and are predominantly ...

A complex set of factors is causing decline of Pacific madrone (Arbutus menziesii) in the Puget Sound region; yet, some trees remain healthy. It is unclear why they do. We are investigating the hypothesis that symbiotic associations between the roots of madrone and soil-dwelling fungi make the trees less susceptible to disease. The effect could occur either directly or by providing physical lin...

Studies were conducted at the horticulture unit of Sokoine University of Agriculture, Morogoro, Tanzania, to assess the incidence and effect of mango weevil, Cryptorhynchus mangiferae (F.) (Coleoptera: Curculionidae), infestation on mango, Mangifera indica L., seed viability. Three polyembryo mango cultivars ('Sindano nyeusi', 'Sindano nyeupe', and 'Dodo') as well as three monoembryo mango cult...

Species of Botryosphaeria are among the most serious pathogens that affect mango trees and fruit. Several species occur on mangoes, and these are identified mainly on the morphology of the anamorphs. Common taxa include Dothiorella dominicana, D. mangiferae (= Natrassia mangiferae), D. aromatica and an unidentified species, Dothiorella 'long'. The genus name Dothiorella, however, is acknowledge...
