Abstract

Significant growth reduction of blackgram cv. T-9 was recorded at an initial inoculum level of 1000 J2 of Meloidogyne incognita per kg soil which was the damaging threshold level. The rate of nematode reproduction was maximum at the lowest inoculum density and vice versa. Similarly, the damaging threshold level of Fusarium oxysporum was recorded at the initial inoculum level of 4 g mycelial mat/kg soil. Out of 62 germplasms/cultivars of blackgram, screened against mixed inoculation of M. incognita and F. oxysporum, none was recorded resistant. Four varieties viz., DPU-88-2, WBU-104, DPU-88-5 and NDU-88-9 exhibited moderate resistance.
