Varietal dependent response of barley to soil-borne Waitea circinata infection

Occurrence of Brown Blight Caused by Waitea circinata var. zeae on Cool Season Turfgrass in Korea

In 2010, disease symptoms, including necrotic lesions on stems and leaves with circular yellow-brown or irregular brown color patches, were observed on cool-season turfgrass at golf courses (OHCC) and the Daegu University research farm in Gyeongbuk, Korea. We isolated the causal agent and identified it as Waitea circinata var. zeae by morphological characterization and molecular analysis. To th...

Selective response of Ricinus communis seedlings to soil borne rhizoctonia infection

Seedlings of Ricinus communis tolerated soil-borne Rhizoctonia infection in strain dependent manner. There was no connection revealed between pathogenicity of strains and their origin or taxonomic position, however, the castor plant proved to be susceptible to most strains highly pathogenic to other host plants as well. Rhizoctonia zeae (teleomorph: Waitea circinata), a species new for European...

Biocontrol strategy, Compost, Soil-borne pathogens management

The effect of different compost-soil ratios on the incidence of Pythium aphanidermatum causing tomato damping off was tested in a greenhouse experiment. The inoculum density of 5% was determined to be suitable for inoculation in compost experiments based on investigations of disease incidence with 5, 10 and 20% inoculum densities. To evaluate the effect of compost on incidence of tomato damping...
