The antagonistic potentiality of some soil fungi against Ceratocystis paradoxa (C.Moreau) a pathogen causing Pineapple disease in sugarcane was studied by dual culture method. The pathogen Ceratocystis paradoxa and some individual species of the soil fungi viz Aspergillus awamori, A. niger, Gliocladium virens, Penicillium citrinum, Trichothecium sp, Trichoderma glaucum, T. harzianum, T. hirsuta, T. koeningii and T. viride were grown on PDA medium individually. Three replicates for each set were maintained. The colony interactions between the pathogen and the soil fungi were assessed the following model proposed by porter (1924) and Diekinson and Broadman (1971). The results were observed and recorded.
