INTERACTION OF MELOIDOGYNE INCOGNITA RACE-3 AND MACROPHOMINA PHASEOLINA IN A ROOT-ROT DISEASE COMPLEX OF CHICKPEA

Z. A. Siddiqui, S. I. Husain

Abstract


The growth of chickpeas and nodulation was adversely affected by the presence of both Meloidogyne incognita race-3 and Macrophomina phaseolina. Disease severity increased with increasing inocula and various combinations of M. incognita and M. phaseolina had synergistic effect on plant growth reduction. The rate of nematode multiplication was density dependent. Increase in the inoculum level of M. phaseolina progressively decreased nematode multiplication and root galling while root-rotting increased with the increase in the combined inocula of M. phaseolina and M. incognita.
