Toxin Produced By Oyster Mushroom Effective Against Nematodes

Pleurotus_ostreatus_1

The toxin produced by pleurotus ostreatus reduces the head size of nematodes.

“Many detrimental nematodes exist, including parasitic plant and animal nematodes. The Pleurotus ostreatus (oyster mushroom) is a famous mushroom that preys upon live nematodes. However, there have been no details reported on the mechanism of this predatory activity. Therefore, we investigated the predatory relationship between the nematode and P. ostreatus as a potential way of exterminating other various detrimental nematodes. Upon invasion by the nematode, the mushroom defends itself by causing the nematode’s head to shrink in size (anti-nematode activity). Our data suggest that this anti-nematode mechanism is associated with the peroxide of linoleic acid.”

Maybe this could be useful for things such as root-knot nematodes. Growing Oyster Mushrooms on your patch could turn out to not only tasty but also act as a natural “pesticide” as well. I’ll certainly be inoculating a few logs for the allotment this summer, maybe even some burlap sacks like Paul Statmets mentions in the last video, I believe he said the weaving is conductive to the fungi developing quickly.
