Abstract:
Pleurotus Ostreatus has ability to act as a Nematophagous fungus, it paralyses and killed nematodes when it come in contact with the hyphae by means of some toxin secreted by the Pleurotus fungus at in vitro condition. In this experiment five different plant parasitic nematodes were assessed in vitro for understanding their killing behavior and mortality period. One species of nematode is resistant to P. Ostreatus, while the other four species are killed by the toxin droplet. Oyster mushrooms are Nematophagous toward some nematodes but are also consumed by others in three of the four families assayed. Species-specific interactions point to the need for studies of the host ranges of "Nematophagous" fungi, especially if they are to be used for biological control. Oyster mushroom shows antagonistic activity against nematodes within 24 hours. Nematodes were inoculated on water agar plates on which a single sparse fungal colony of one of the above mentioned fungi was grown. Different types of nematodes were quickly immobilised after inoculating the plates with Pleurotus species, and the mortality percentage (from 23.33 to 100% in 3h to 24h periods) of nematodes varied among nematode species.
