Abstract:
The results of poisoned food technique against Sclerotium rolfsii, Rhizoctonia solani and Fusarium oxysporum f.sp. ciceri revealed that three concentrations of six fungicides differ significantly in minimizing the radial growth of these pathogens. As concentration of fungicide increased, gradual decrease in the radial growth of these pathogens was observed. The radial growths of these fungi were also influenced significantly due to fungicide x concen- -tration interactions. At 500ppm concentration, complete inhibition of mycelial growth of S. rolfsii was observed in fungicide treatment with Mancozeb, CM 75 and Carzate (all content > 60% Mancozeb). Beside these, Contaf and Benomyl at 1500ppm concentration were found effective in checking mycelial growth of S. rolfsii. Use of CM 75 even at lower concentration i.e. 500ppm resulted in 100 per cent inhibition of mycelial growth of R. solani. Carzate and Mancozeb were also found effective and inhibited 68.14 to 96.28 per cent growth of R. solani. Beside these, Contaf at 1500ppm concentration was inhibited 80.36 per cent growth of R. solani. CM 75 at all concentrations and Carzate at 1500ppm showed complete inhibition of the growth of F. oxysporum f.sp. ciceri. Carzate, Contaf and Mancozeb were also found effective and inhibited more than 60 per cent growth of F. oxysporum f.sp. ciceri at all concentrations.
