Abstract

Aspergillus niger van Tiegh isolated from the rhizosphere of coffee seedlings was found to be antagonistic to the collar rot pathogen, Rhizoctonia solani Kuhn, in vitro and hyperparasitised R. solani completely in dual culture. The mode of hyphal interaction and parasitism of R. solani by A. niger indicated the direct growth of the mycoparasite towards its host and as a consequence the host hypha became vacuolated, collapsed and finally disintegrated. Seed treatment with A. niger spores increased germination. Under glasshouse and field conditions using natural inoculum of R. solani and under artificially infested soils, seed treatment with A. niger reduced the incidence of collar rot disease. A soil incorporation of inoculum was superior to the seed treatment. The possibility of using A. niger as a biocontrol agent against collar rot of coffee is discussed.
