Two methods were compared for the isolation from soil of the fungus Ceratocystis paradoxa, causal agent of pineapple disease of sugarcane. The semi-selective v8-a medium permitted both a qualitative and a quantitative assessment and colonies characteristic of the pathogen were observed within two days. The recovery power of the medium was lowered when the spore concentration was high probably due to crowding of spores and aggregation. The range of spore densities detected was 0 to 9963/g of soil. Fifty percent of all fields sampled were infected and most had less than 500 spores/g of soil. The presence of contaminating fungi in the medium, despite the presence of fungicides, did not affect the enumeration of colonies of C.paradoxa provided readings were taken within 2-3 days after incubation. The tissue bait technique was a qualitative assay and results were available within two weeks. The two methods were comparable with 82 | |
