Integrating mushroom cultivation in the existing farming systems not only supplements the income of the farmers but also promotes proper recycling of agro- residues thereby improving soil health and promoting organic agriculture. Therefore, there is need to have mushroom which can grow during summer months being longer shelf-life. Milky mushroom (Calocybe indica) fits well under these conditions because of its ability to grow at temperature above 30°C, white sporophore, excellent shelf life, high biological efficiency (80-90%) and easier in post-harvest handling. The green mould due to Trichoderma harzianum is of common occurrence in milky mushroom cultivation and therefore also called as Trichoderma spot, Trichoderma blotch, Trichoderma mildew etc. and causing losses from 63-65% in cultivated mushrooms (Bhatt and Singh, 2000). It is a ubiquitous fungus found in air, soil, plant materials and other substrates. Disease control in mushroom farms by treatment of casing soil with disinfectants and fungicides. Gae (2008) also reported that benomyl and thiabendazole were The toxicants (fungicide and botanicals) showing maximum efficacy against the pathogen and minimum efficacy against milky mushroom (Calocybe indica) mycelia as per results of in vitro studies were further evaluated against T. harzianum under in vivo condition in mushroom house. Among fungicides only Bavistin (@150 ppm) and out of three botanicals only Nimbicidin (@4 per cent) were selected for management of the green mould disease in milky mushroom cultivation in bags. The different yield parameters and yield were recorded and found that days for spawn run (DFSR), days for pinhead formation (DFPF) and days for first harvest (DFFH) were significantly reduced in case Bavistin and Nimbicidin treatment.
