Pathogenicity of Macrophomina phaseoli on Jute in the Presence of Meloidogyne incognita and Hoplolaimus indicus
Abstract
Seedlings of Corchorus capsularis (cv. C4444) were inoculated with Meloidogyne incognita, Hoplolaimus indicus, and a fungus pathogen of jute, Macrophomina phaseoli, separately and in all possible combinations. The significant damage of jute plants caused individually by the pathogens was aggravated when the fungus was associated with either of the nematode species. M. incognita alone caused greater damage than either H. indicus or Macrophomina phaseoli alone. Plants inoculated with M. incognita and Macrophomina phaseoli were more severely damaged than plants inoculated with H. indicus and the fungus. Plant growth was minimum and disease symptoms were maximum when all pathogens acted together. In the presence of the fungus, M. incognita produced fewer galls. The reproduction of H. indicus was not influenced by the other organisms.Downloads
