Abstract

An experiment was conducted to determine the impact of different virulent endemic pathogens of water hyacinth, namely, Alternaria alternate, Alternaria eichhorniae, Fusarium pallidoroseum, and Curvularia lunula, in various combinations. The pathogens were isolated from diseased plant parts of water hyacinth collected during periodical surveys, in the water bodies of Jabalpur. All pathogens were compatible with each other in terms of growth, sporulation and damage potential, except A. eichhorniae whose growth appeared inhibited in the presence of the other test pathogens. The combined effect of various pathogens was better than any of the pathogens tested alone. Combination of A. alternate + C. lunate + F. pallidoroseum resulted in maximum disease development, followed by A. alternata + C. lunata. A. alternate + F. pallidoroseum and C. lunate + F. pallidoroseum combinations were also effective.
