Re: [compost_tea] Re: Root-knot nematodes



Rich Buckley, a researcher at Rutgers told me that Arthobotrys (those fungi that lasso and kill phytopathogenic nematodes) are ubiquitous.  In his examination of soils from all over the world, every sample had them.

the NSF, in the mts in Oregon.  The forests around Fort Lewis in
Washington State  - again, undisturbed - have good diversity, but be
careful of the tanks rolling around.  They get fairly nasty about
unauthorized people on the property, so maybe not a good place to go
on your own.  And again, you have to know where the place has not
been disturbed.

Send them to SFI for ID.  Or hope for the best in your compost.
