The studies were conducted under in-vivo conditions to see the effect of weather parameters (temperature and relative humidity) and different components of casing materials on wet bubble disease of white button mushroom. The results showed AUDPC and rate of disease increase (r) as 375.09 and 0.61 respectively. Simple correlation showed negative correlation between disease incidence with mean temperature (-0.311) and also negative with RH (-0.097) whereas, multiple correlation coefficient between disease incidence with mean temperature and mean relative humidity were not significant. Regression equation i.e. Y = 111.45 - 17.7X1 +3.30X2 obtained showed that prevailing mean temperature had negative impact while relative humidity had positive impact on development of disease. Regarding casing materials coco peat provided least disease incidence of 1.3 per cent and maximum yield was obtained in formalin treated coco peat + FYM (1.44kg), while sand resulted in minimum yield (0.30kg) of sporophore under in-vivo conditions.

Abstract


The studies were conducted under in-vivo conditions to see the effect of weather parameters (temperature and relative humidity) and different components of casing materials on wet bubble disease of white button mushroom. The results showed AUDPC and rate of disease increase (r) as 375.09 and 0.61 respectively. Simple correlation showed negative correlation between disease incidence with mean temperature (-0.311) and also negative with RH (-0.097) whereas, multiple correlation coefficient between disease incidence with mean temperature and mean relative humidity were not significant. Regression equation i.e. Y = 111.45 - 17.7X1 +3.30X2 obtained showed that prevailing mean temperature had negative impact while relative humidity had positive impact on development of disease. Regarding casing materials coco peat provided least disease incidence of 1.3 per cent and maximum yield was obtained in formalin treated coco peat + FYM (1.44kg), while sand resulted in minimum yield (0.30kg) of sporophore under in-vivo conditions.
