Abstract

Interaction study between the Rotylenchulus reniformis and Rhizoctonia bataticola (virulent and avirulent strains) revealed that avirulent strain of R. bataticola and the virulent one were equally effective in causing seedling root-rot of cotton in presence of R. reniformis. In virulent strain of fungus R. bataticola, the disease set one week earlier in different combinations of nematode and the fungus than fungus alone. Among the different combinations, nematode inoculated 15 days prior to fungus inoculation (N-F) proved highly detrimental, causing cent per cent root rot with both the strains of fungus followed by simultaneous (FN) and fungus inoculated 15 days prior to nematode (F-N).
