Abstract

Axtensive survey was conducted during spring and autumn seasons of 2019-20 and 2020-21 in major mushroom growing areas of Jammu, Samba and Udhampur districts of Jammu division to record the status of the disease. The survey revealed that dry bubble disease was prevalent in all mushroom growing districts with varied degrees of incidence. The overall mean disease incidence was 6.52 per cent both years in three districts, the disease incidence was more (5.76 and 6.22 %) in spring than in autumn season (6.27 and 7.39 %). The highest disease incidence (7.22 %) in Jammu district followed by (6.49 %) in Samba district and the lowest disease incidence (5.85 %) in Udhampur district. In vitro study of different bio agents against Veticillium fungicola revealed that inhibition of mycelia growth was maximum with Trichoderma harzianum (46.43 %) followed by Trichoderma viride (35.80 %) and P. fluorescens (17.43 %). In vitro evaluation of different botanicals viz., Azadirachta indica(neem leaf), Aza

Conclusion

White button mushroom cultivation in Jammu division in primarily in the hands of resource-poor growers. The prevalence of unhygienic conditions in and around the mushroom farms and lack of pasteurization facility result in recurrence of wet bubble and other mould diseases causing heavy economic losses to these growers. The disease can be managed at farmer’s field levels by the use of safer fungicides, botanicals and bio agents on or in the casing soils and adhering to farm sanitation. This study has found two most promising botanicals, A. indica and A. indica +Lantana camara that were able to inhibit the infection of dry bubble disease (V. fungicola) of white button mushroom (A. bisporus) under both in-vitro and in-vivo conditions. In in-vitro study, A. indica and A.indica + Lantana camara have been best treatments among all botanicals as they inhibit the growth of V. fungicola. In in-vivo study Incorporation of botanicals such as A. indica or A. indica +Lantana camara as dry powder
