Rhizoctonia solani represents an important plant pathogenic Basidiomycota species complex and the host of many different mycoviruses, as indicated by frequent detection of dsRNA elements in natural populations of the fungus. To date, eight different mycoviruses have been characterized in Rhizoctonia and some of them have been reported to modulate its virulence. DsRNA extracts of the avirulent R...

Chemical fungicides are used worldwide for enhance crop yield and control plant diseases. When crops are treated with chemical fungicides over a long period then some fungi develop resistance to these chemicals beside this these chemicals are harmful to other non target microorganism and disturb microbial community of soil. In view of these facts, it is urgent need to discover eco friendly, ren...

Dickeya solani is one of the most important pectinolytic phytopathogens responsible for high losses in potato, especially in seed potato production in Europe. Lytic bacteriophages can affect the structure of the host population and may influence spread, survival and virulence of the pathogen and in consequence, infection of the plant. In this study, we aimed to acquire information on the viabil...

cots in the family Commeliaceae. The basic morphology of these plants appears to favor root-knot nematode development in aboveground plant parts. Leaves of both plants develop in the crown near the soil; they are large, 20-30 cm long, and densely arranged so that nematodes on younger leaves are protected from direct solar irradiation. The dense pubescent foliage, especially the convoluted young...

The interaction between endophytic biocontrol agent Chaetomium spirale ND35 and the soil-borne plant pathogen Rhizoctonia solani was studied by light microscopy and transmission electron microscopy (TEM), as well as further investigated by gold cytochemistry to assess the potential role of cell wall degrading enzymes (CWDEs) during the mycoparasitic process. Macroscopic observations of fungal g...

AIM The main goal of the present research conducted to assess the in vitro activity of the nematophagous fungi Duddingtonia flagrans, Fusarium solani, Verticillium chlamidosporium, and Trichoderma harzianum. MATERIAL AND METHODS Four isolates of fungi including D. flagrans, F. solani, V. chlamidosporium and T. harzianum were used in this study. Horse faeces were used to provide the larvae sta...
