An experiment was conducted to find out variation in isolated Rhizoctonia solani based on radial mycelial growth and sclerotial production. Five isolates of Rhizoctonia solani representing five clusters group were selected and were grown at different levels of temperature and pH on potato dextrose agar (PDA). It was observed that optimum temperature and pH for growth and scierotial production v...

The antifungal activity of phenolic compounds extracted from olive pomace against Alternaria solani, Botrytis cinerea and Fusarium culmorum was investigated. Olive pomace, a by-product of olive oil production, was used as a source of phenolic compounds. The extracted phenolics were added to a medium to reach phenol concentration of 0.1 and 0.2 % (w/v) and tested for their antifungal activity ag...

Alternaria solani was isolated from infected tomato leaves, and Trametes versicolor northern areas of Pakistan established mycelial culture on PDA. Crude Protein extract prepared in 50mM Sodium phosphate buffer by macerating C. (T/C) mycelium. Extracted protein solution (Crude extract) filtered tested for antifungal activity using different concentrations (0.5mg/ml, 1mg/ml, 1.5mg/ml, 2mg/ml) ag...

rhizoctonia solani is the most serious problem on sugar beet beta vulgaris l. grown in north dakota and minnesota. picoxystrobin, a quinone outside inhibitor, and penthiopyrad, a succinate dehydrogenase inhibitor, were used alone and in combinations for controlling r. solani ag 2-2 iiib on sugar beet under greenhouse conditions of 22 ± 2 °c and a 12-h photoperiod. fungicides were applied in-fur...

due to the high antagonistic activity of bacterium, bacillus subtilis (ehrenberg) cohn, three isolates (b.s.ham, 204 and 202) were selected and their efficacy were studied in control of sugar beetdamping–off caused by rhizoctonia solani , in  in vitro and in vivo conditions.  in dual culture on pda, all isolates of b.subtilis inhibited mycelial growth of r.solani.  significantly, volatile metab...

The antifungal effect of 10 plant extracts viz., Thevetia peruviana, Ocimum basilicum, Piper betel, Murraya koenigii, Chrysanthemum coronarium, Polyalthia longifolia, Catharanthus roseus, Pelargonium graveolens, Moringa officinalis and Lawsonia inermis were evaluated by poisoned food technique against Rhizoctonia solani Kuhn, the causal organism of sore shin disease of tobacco. Among all the pl...

the antagonistic effects of rhizobium spp. isolates against rhizoctonia solani (ag-4), the causal agent of bean damping-off were compared with each other in either of the in vitro and in vivo conditions. also their potential to produce such secondary antifungal metabolites as hcn, siderophore and protease were evaluated. the results indicated that, isolate rh3 reduced mycelial growth of r. sola...

The most serious aerial disease of garlic is leaf blight caused by Stemphylium spp. Geographical variation in the causal agent of this disease is indicated. Stemphylium vesicarium has been reported in Spain, whereas S. solani is the most prevalent species recorded in China. In this study, Stemphylium isolates were obtained from symptomatic garlic plants sampled from the main Spanish production ...

HOWELL, C. R., and R. D. STIPANOVIC. 1979. Control of Rhizoctonia solani on cotton seedlings with Pseudomonasfluorescens and with an antibiotic produced by the bacterium. Phytopathology 69:480-482. A strain of Pseudomonasfluorescens antagonistic to Rhizoctonia solani Alternaria sp., and Verticillium dahliae. A Fusarium sp. was only partially was isolated from the rhizosphere of cotton seedlings...
