| 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 woundinoculation 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%. |
