Organic Management of Meloidogyne incognita (Root-knot Nematode) in Dolichos lab lab (Indian Bean) with Aqueous Extracts of Pleurotus ostreatus Oyster Mushroom Spent Compost

This investigation was done to determine the efficacy of oyster mushroom spent compost to control the root knot nematodes. The cultivation of oyster mushrooms yields spent mushroom compost (SMC), which has a unique microbiota that may include additional nematode antagonists and high levels of mycelium residual enzymes, and high humidity. These characteristics make SMC an excellent candidate for biological control. In order to reduce Meloidogyne incognita in Indian beans, this study evaluated the potential of an aqueous extract of SMC from Pleurotus ostreatus cultivation. Invitro experiments on second stage Juveniles (J2) larvae showed successful results with death of the larvae at 50% concentration.
