| Abstract | ||
| Dry bubble disease is one of the most important serious diseases of the cultivated white button mushroom (Agaricus bisporus (Lange) Imbach). It is a cosmopolitan disease having a worldwide distribution. Ten isolates of Lecanicillium fungicola var. fungicola (Preuss) Zare and Gams were collected from mushroom farms. Sensitivity of the isolates to benomyl, carbendazim, carbendazim+iprodione and prochloraz manganese were studied. All the isolates were resistant to benomyl(ED50= 415.45-748.12 mg L-1), carbendazim (ED50= 1123.87-1879.59 mg L-1) and iprodione+carbendazim (ED50= 415.45-748.12 mg L-1). However, most of the isolates were sensitive to prochloraz manganese (ED50=1.62–12.58 mg L-1). As the primary source of the pathogen inoculum is casing soil and insects, stringent environmental hygiene of the mushroom houses will play a very important role in preventing and controlling the disease. | ||
