The experiment on effect of phyto-extracts for control of Trichoderma mould in oyster mushroom cultivation was conducted to study the efficacy of different phytoextracts against Trichoderma mould on growth and yield of oyster mushroom. Results indicated that the minimum days required for spawn run and pinhead formation were recorded by Carbendazim + Formalin (16.33 and 20.33 days) where as among the phytoextracts, T6 Azadirachta indica @ 6% required 17.00 and 21.33 days respectively. Maximum days were recorded for the treatment Ocimum sanctum @ 4% (22.67 and 26.33 days). The time taken for harvestings ranged from 24.00 to 53.67 days for the total three harvesting. The results showed that number of fruits per beds varied from 10 to 68.67 in the first, second and third harvest due to different treatments. The treatment T13 Carbendazim + formalin was found significantly superior over all treatments. The variation in average fruit body weight (3.23 to 6.67 g per fruit), pileus diameter (4.93 to 7.37 cm), stipe length (1.40 to 2.60 cm) and stipe size (2.43 to 3.87 cm) was noted for the different treatments. The observations on yield performance due to different treatments revealed that Carbendazim + Formalin produced maximum yield of oyster mushroom (965.78 g/kg dry substrate). Among the phytoextracts, Azadirachta indica @ 6% produced maximum yield (809 g) while minimum yield (556.78 g) was recorded due to Ocimum sanctum @ 2%. The observation on biological efficiency indicated that Carbendazim + Formalin had recorded maximum biological efficiency (96.57%) followed by the treatment T6 Azadirachta indica @ 6% (80.90 %) while T7 Ocimum sanctum @ 2% had recorded minimum biological efficiency (55.67%).
