metallic silver nanoparticles have been reduced from silver nitrate by employing the extracellular enzymatic machinery of edible white button mushroom (agaricus bisporus). the physical properties of these particles, size and shapes have been determined using techniques like tem, ftir and xrd and were reported in our earlier report. but, what stands of paramount importance in the present context...

Rhizoctonia stem canker and black scurf diseases of potato are caused by the fungus Rhizoctonia solani Kühn (teleomorph Thanatephorus cucumeris [A. B. Frank] Donk) and can be found on all underground parts of the plant at various times during the growing season. Rhizoctonia solani (Deuteromycetes, Mycelia Sterilia) is a species complex of 13 anastomosis groups (AGs), which are categorized accor...

AIMS To simplify the determination of the nuclear condition of the pathogenic Rhizoctonia, which currently needs to be performed either using two fluorescent dyes, thus more costly and time-consuming, or using only one fluorescent dye, thus less accurate. METHODS AND RESULTS A red primary fluorescence (autofluorescence) of the hyphal cell walls and septa of Rhizoctonia spp. with green excitat...

Rhizoctonia blight is a common and serious disease of many turfgrass species. The most widespread causal agent, Thanatephorus cucumeris (anamorph: R. solani), consists of several genetically different subpopulations. In addition, Waitea circinata varieties zeae, oryzae and circinata (anamorph: Rhizoctonia spp.) also can cause the disease. Accurate identification of the causal pathogen is import...

Sugarbeet (Beta vulgaris L.) germplasms FC716 through FC719 (Reg. no. GP-143 to GP-146, P1 574627 to P1574630) were developed by the USD A-ARS in cooperation with the Beet Sugar Development Foundation. Each of these germplasms was developed from genetically different and distinctive sources. These lines should provide resistance to root-rotting strains (AG-2-2) of Rhizoctonia solani Kilhn and p...

The genus Rhizoctonia DC (1805) has long been studied as an important soilborne pathogen that causes a wide variety of symptoms because it is a non-specialized pathogen. Rhizoctonia sensu lato is characterized by the lack of conidiogenous cells and this taxon is composed of two groups based on the number of nuclei per cell: the multinucleate group that belongs to Rhizoctonia s. str. and the bin...

The study was conducted for the purpose of knowing effect mycorrhizal fungus on controlling root rot disease caused by pathogenic Rhizoctonia solani, field experiment included four treatments and each treatment had five replicates, were as follows (Control, Mycorrhiza, Rhizoctonia, Rhizoctonia), where percentage infection with (0.00, 0.00, 96.91, 63.58), respectively. while growth indicators st...
