Abstract

Pathogens isolated from various potato tuber rots were studied for dominance and succession. Eleven pathogens, 9 fungal and 2 bacterial in 55 combinations were tested for dominance and six pathogens, 4 fungal and 2 bacterial (in both sequences) in 30 combinations for succession. In general, the order of dominance was Bacillus sp, Erwinia sp, Fusarium oxysporum, Macrophomina phaseolina, Penicillium sp, Phoma humicola, Sclerotium rolfsii, Verticillium sp, Rhizopus sp, Chaetomium nigri color and Alternaria alternata.
