Abstract Husk spot caused by the Pseudocercospora macadamiae fungus induces premature abscission of fruit in many industry standard macadamia cultivars. Fungicides and other management strategies add to farm costs, thus breeding for varietal resistance is important. Genetic parameters husk symptom expression had not previously been estimated. To guide selection methods field resistance, over 30...

O feijão e o tomate são culturas de grande relevância no Brasil, particularmente estado do Paraná. A mancha angular a septoriose doenças importantes nestas culturas. Os cultivos base agroecológica estão ganhando em diferentes partes mundo, vêm sendo estimulados ciência homeopática tem sido divulgada como uma ferramenta para este tipo agricultura. bioterápicos produzidos segundo farmacotécnica h...

Many fungal genera have been defined based on single characters considered to be informative at the generic level. In addition, many unrelated taxa have been aggregated in genera because they shared apparently similar morphological characters arising from adaptation to similar niches and convergent evolution. This problem is aptly illustrated in Mycosphaerella. In its broadest definition, this ...

Anthelmintic resistance creates a major hitch over the decades throughout the world. As per WHO only few drugs are frequently used in the treatment of helminth infestations in human beings. In view of this, an attempt has been made to study the anthelmintic activity of some newly synthesized 1-substituted imidazoles (1a-1d, 2a-2d) were synthesized and characterized by their spectral data. All t...

UNLABELLED Septoria represents a genus of plant pathogenic fungi with a wide geographic distribution, commonly associated with leaf spots and stem cankers of a broad range of plant hosts. A major aim of this study was to resolve the phylogenetic generic limits of Septoria, Stagonospora, and other related genera such as Sphaerulina, Phaeosphaeria and Phaeoseptoria using sequences of the the part...

Anthracnose caused by the fungal pathogen Colletotrichum gloeosporioides causes serious post harvest losses of avocado fruit worldwide. Typically, infections are initiated in the field on unripe fruit, but remain quiescent as germinated appressoria until fruit ripening. Over the past two decades pepper spot, a pre-harvest disease also caused by C. gloeosporioides, has been reported on 'Hass' av...

During 1980 a survey of the parasites of freshwater fish was conducted in the Sabie and Crocodile Rivers in the southern part of the Kruger National Park, Transvaal. A new species of Phyllodistomum, Braun, 1899, for which the name Phyllodistomum bavuri is proposed, was found in the urinary bladder of many of the catfish, Clarias gariepinus (Burchell, 1822), examined. The new species resembles P...

Cyphellophora and Phialophora (Chaetothyriales, Pezizomycota) comprise species known from skin infections of humans and animals and from a variety of environmental sources. These fungi were studied based on the comparison of cultural and morphological features and phylogenetic analyses of five nuclear loci, i.e., internal transcribed spacer rDNA operon (ITS), large and small subunit nuclear rib...

Various systemic fungicides and a non-systemic fungicide (copper ammonium carbonate) were evaluated as possible alternatives to copper-oxychloride and benomyl, for control of preand postharvest diseases of avocados. Foliar applications of cyproconazole, flusilazol or copper ammonium carbonate were as effective in controlling Cercospora spot as copper-oxychloride and benomyl, but were less effec...
