Abstract

Seven kharif crops, namely, maize, sorghum, cowpea, soybean, green gram, sesame and ridge gourd were evaluated for pathogenicity of Rhizoctonia solani and Fusarium solani causing root-rot of guar. Out of these, three, viz. soybean, green gram and sesame developed 36 to 51 per cent root-rot due to these pathogens and were considered susceptible, while others were resistant, and may be used for crop rotation to reduce the soil-borne inoculum of these pathogens.
