WTB Bacillus thuringiensis japonensis, nematodes?
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 . . .
