Impact of meloidogyne incognita in incidence of root-rot disease caused by Rhizoctonia solani in tomato

摘要

Root-rot disease caused by Rhizoctonia solani in tomato cv. Pusa Ruby was recorded in highest score (5.50), when the plants coinoculated with Meloidogyne incognita than in the plants inoculated with fungus alone. The plant bio-mass was impeded by theinfection of both components in proportional to highest disease index (5.50). Reproduction of nematode suppressed wheu increased the fungal inoculum. Highest pathogenic impact was observed in N+F than that of NaF and NbF combinations.
