Abstract
Several pathogens associated with bulb rot of lilies in storage house were identified with respect to rot types. Rot patterns were grouped into four different types; brown rot of bottoms, brown rot of shoots, water-soaked rot and blue mold. Brown rot of bottoms was the highest in frequency with 72.5%, and brown rot of shoots the least with 23.0%. Dominant pathogens were differed with rot patterns, brown rot of bottoms by Fusarium oxysporum, blue mold and brown rot of shoots by Penicillium brevicompactum and P. fellutanum. In wound-inoculation tests, Penicillium and Fusarium isolates caused severe rot on the bulbs. Bulb disinfection before storage by captan showed the most prominent control value of 95.2% followed by thiophanate-methyl with 85.6%.
