Compatibility Analysis of Mushroom with different Botanicals in In vitro Condition

White button mushroom [Agaricus bisporus (Lange) Imbach] is the most popular cultivated edible mushroom, fetching high price and still dominating in Indian and International market. However, the limiting factor for its successful cultivation is the occurrence of competitor moulds. The present investigations were carried out in the laboratory Department of Plant Pathology, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj, Uttar Pradesh. In this experiment different botanical (seed extract) viz., Trachyspermum ammi (Ajwain), Foeniculum vulgare (Saunf), Anethum graveolens (Soa), Trigonella foenumgraecum (Methi) were evaluated to test their compatibility with Agaricus bisporus. The botanicals (seed extract) were evaluated in vitro through poison food technique at 10, 20 and 30% concentrations and 24, 48 & 72 hours of incubation. The maximum radial growth of Agaricus bisporus was observed in T0-Control (Agaricus bisporus) (16.45mm), (17.12 mm) and (17.22 mm) and minimum in T1 - Trachyspermum ammi (Ajwain) (1.46mm), (0.83mm) and (0.60mm) at 10, 20 and 30 percent concentration respectively. Maximum percentage of inhibition was observed in T1 - Trachyspermum ammi (Ajwain) (91.11%), (95.13%) and (96.50%) at 10, 20 and 30 percent concentration respectively.
