Water extracts from spent mushroom substrate (SMSE)of edible mushrooms, Pleurotus eryngii, Hericium erinaceus and Lentinula edodes promoted growth of pepper seedling. Mycellial growth rate of Phythopthora capsici and Fusarium oxysporum was dramatically inhibited by 100% and 70% on PDA added with SMSE of H. erinaceus. SMSEs from H. erinaceus, P. eryngii, and L. edodes effectively reduced the disease severity of Phytophthora blight of pepper caused by Phytophthora capsici to 75%, 10% and 35%, respectively. These results suggested that SMSE from the mushrooms have dual effects that suppress phythopthora blight disease and promote plant growth of pepper.

Bacillus velezensis HKB-1 was isolated from the composted spent mushroom substrate of Lentinula edodes (LeCSMS) and inhibited mycelial growth of phytopathogenic fungal species, Phythhopthora capsici, Collectotrichum coccodes and Fusarium oxysporium by more than 70%. B. velezensis HKB-1 showed bacterial growth rate 10 to 100 times higher than that of other commercial bacterial media in water extract of LeCSMS supplemented with 1% molasses. The LeCSMS medium was effective in promoting the growth of pepper and controlling Phytophthora blight disease of pepper.
