Ginseng damping-off, caused by the fungal pathogens Rhizoctonia solani and Pythium sp., is a critical disease in ginseng seedling. In a continuing effort to find microorganisms with the potential of acting as a biocontrol agent against Rhizoctonia damping-off, we found that a Streptomyces sp. A501 showed significant antifungal activity against Rhizoctonia solani. In field experiment to test the...

To date, much of the genetics of the basidiomycete Thanatephorus cucumeris (anamorph = Rhizoctonia solani) remains unknown. Here, we present a population genetics study using codominant markers to augment laboratory analyses. Seven single-copy nuclear RFLP markers were used to examine 182 isolates of Rhizoctonia solani AG-1 IA collected from six commercial rice fields in Texas. Thirty-six multi...

Sheath blight, caused by Rhizoctonia solani anastomosis group 1 subgroup 1A (AG1-1A), is one of the most devastating rice diseases worldwide. Here, we report the draft genome sequence of R. solani AG1-1A strain 1802/KB isolated from a popular Malaysian rice variety. To the best of our knowledge, this is the second reported representative genome from AG1-1A.

Gottlieb, David (University of Illinois, Urbana), and James L. Van Etten. Changes in fungi with age. I. Chemical composition of Rhizoctonia solani and Sclerotium bataticola. J. Bacteriol. 91:161-168. 1966.-The chemical composition of the mycelium of Rhizoctonia solani and Sclerotium bataticola was determined in cells of various ages. The percentage, per unit of dry weight, of soluble amino nitr...

Soreshin of cotton was more severe from combined infections of Rhizoctonia solani and Meloidogyne incognita than from either organism alone, when both critical soil temperature and inoculum concentrations were present. Optimum soil temperatures for disease development from combined infections were 18 and 21 C. Either 2,500 or 5,000 M. incognita larvae per plant, combined with R. solani, increas...

Rhizoctonia sheath diseases of rice, comprising sheath blight, sheath spot and aggregate sheath spot, cause significant yield losses in many rice-growing regions of the world. The emergence of Rhizoctonia sheath diseases as economically important rice diseases is of recent date and has been attributed to the intensification of rice-cropping systems with the development of new short-stature, hig...

damping off caused by rhizoctonia solani (isolate ag4) constrains growing soybean in the north iranian province of golestan. the pathogen was grown on malt agar containing 0, 50, 100 or 200 ppm trifluralin then its vegetative growth and virulence were evaluated. the response of soybean cv. williams seedlings grown in soil containing 0, 0.5, 1 and 2 ?g ai g-1 trifluralin was investigated. on mal...

The cucumber (Cucumis sativa L.) is often subjected to several fungal diseases. Rhizoctonia solani-induced damping-off and root rot are the most common diseases reported from commercial greenhouses of eastern area Saudi Arabia. objective current study explore antagonistic activity four Trichoderma species against R. solani in vitro vivo. Ten isolates (eight belonging AG-4 two AG-A AG2-1) were s...
