Wet Bubble is a devastating disease in the crop production of mushrooms. Wet bubble disease causes extensive damage by bringing soft rot or decay of whole fruiting body. If not controlled well in time, the pathogen causes havoc damaging the entire crop. It causes serious crop losses in mushroom farms in India. The aim of the present study was to check the in vitro and in vivo efficacy of antagonists against Wet Bubble (Mycogone perniciosa) associated with the cultivation of Agaricus bisporus. Among bacterial antagonists evaluated in vitro, all the test antagonists, Pseudomonas flourescens, Bacillus subtilis and Azotobacter sp., exhibited stimulatory effects of varying degrees on A. bisporus mycelium. Pseudomonas flourescens-103, Bacillus subtilis-116 and Azotobacter sp.-106 gave the highest mycelial growth inhibition of 100.0, 98.88 and 98.51 percent of the pathogen fungus, respectively. The incorporation of bacterial antagonists such as P. fluorescens, B. subtilis or Azotobacter sp. at different concentrations in pathogen-infested casing also yielded appreciable disease control with corresponding yield gains.
