WTB Bacillus thuringiensis japonensis, nematodes?

lifespeed(9B San Jose)July 13, 2012

Where can I buy Bacillus thuringiensis japonensis 'Buibui' (Btj)? I am trying to combat Japanese Beetle grubs in my lawn. Also, pathogenic nematodes like Heterorhabditis bacteriophora or Steinernema glaseri are supposed to provide a synergistic effect together with the Bacillus.

But this stuff is not available at Home Despot . . .

Any ideas?

If your San Jose is in California, you don't have Japanese beetles.

Contact your county's Extension Service office for an ID when you take in samples. Locate your office with this map

The reports I have seen about "Bacillus thuringiensis japonensis" indicate it is giving very spotty results. A tried and relatively effective disease for Japanese Beetles is "Bacillus popilleae", Milky Spore Disease which is much more readily available.
