Branch canker is the main stem disease of Camellia sp. caused by Macrophoma sp. In this study, branch canker pathogen was isolated, bought to pure culture and maintained in potato dextrose agar medium (PDA). A total number of 150 bacterial and 40 fungal strains were isolated from different agro climatic zone of south India, which are region specific and native strains (resembling Pseudomonas spp. Bacillus spp. and Trichoderma spp.). Among the total number of bacterial and fungal isolates, 6 bacterialand 3 Trichoderma spp. Showed antagonistic effect against the branch canker pathogen. The study clearly indicates that Bacillus spp. Pseudomonas spp. followed by Trichoderma spp. showed higher antagonistic potential against the test pathogen. The study also includes that, the selected botanical fungicides, neem kernel extract, garlic extract, Aloe vera, Tu.. View More»
