White button mushroom (WBM) extracts down‐regulate in vitro interleukin‐6 (IL‐6) secretion by non‐activated THP1 cells: Implication on cardiovascular diseases.

The study was undertaken to determine antifungal potentials of some plant extracts against dry bubble (Verticillium fungicola) disease of white button mushroom (Agaricus bisporus). Twelve botanicals namely, Allium cepa, A. sativum, Saraca asoca, Aloe vera, Azadirachta indica, Lantana camara, Ocimum sanctum, Solanum lycopersicum (Lycopersicon esculentum), Tagetes erecta, Psidium guajava, Catharanthus roseus and Aparagus racemosus were evaluated in-vitro and in-vivo for their efficacy against both A. bisporus and V. fungicola, causing dry bubble disease of mushroom. The efficacy of botanicals was examined by poison food technique in in-vitro. The percent inhibition produced by botanicals against V. Fungicola recorded in-vitro was; A. cepa (25.87%), A. sativum (24.70%), S. asoca (12.35%), A. vera (22.35%), A. indica (35.11%), L. camara (28.48%), O. sanctum (20.59%), S. lycopersicum (20.34%), T. erecta (14.11%), P. guajava (15.11%), C. roseus (18.11%) and A. racemosus (13.52%). Among these plant extracts, A. indica was found best treatment followed by L. Camara and A. Cepa. Plant extracts showing maximum efficacy against V. fungicola and minimum inhibition against mushroom were further evaluated against V. fungicola infection in mushroom crop room (in-vivo test). In in-vivo test, the polybags which receive A. indica show maximum mean increase in yield (43.46%) over control and exhibited minimum mean disease incidence (27.7%).

The isolates of two mycopathogenic fungi Verticillium fungicola and Mycogone perniciosa, and a commercial isolate of white button mushroom Agaricus bisporus were tested for sensitivity to prochloraz, benomyl, and iprodione in vitro. The pathogens were isolated from the diseased mushrooms originating from mushroom farms in Vracevsnica (Gornji Milanovac) and Pozarevac in Serbia. Prochloraz and iprodione were highly toxic to both M. perniciosa and V. fungicola. The isolate of M. perniciosa was also very sensitive to benomyl, whereas the toxicity of benomyl to V.fungicola was extremely low. Among the fungicides investigated, iprodion was the most toxic and benomyl the least toxic to the isolate of white button mushroom. Chemical control of both dry and wet bubble is possible by prochloraz and iprodione. Moreover, successful control of wet bubble causal agent can be obtained by benomyl as well, due to high toxicity of this fungicide to the pathogen and low toxicity to white button mushroom. In addition, use of benomyl alternating prochloraz provides resistance management strategy providing that a given farm is free of V.fungicola population.
