Somewhat more natural pesticides, with fewer unwanted side effects, include milky spore disease (MSD or Bacillus popilliae Dutky) and beneficial nematodes (Heterorhabditis spp.)

The spore disease?

Another is milky spore disease, which is specific for the grubs of Japanese beetles.

Milky spore disease.

Well, what about milky spore disease?

Their first mission was a dull but necessary crash priority (Medical got Helva), rushing a vaccine to a distant system plagued with a virulent spore disease.

The first line of attack is to find out if a previous owner has inoculated the lawn with Bacillus popilliae, or milky spore disease, a bacterium that is fatal to grubs but harmless to other insects and humans.

One of the most popular biological controls is the use of milky spore disease that is specific for grubs and harmless to humans.

During that stage, it is susceptible to a fatal disease called milky spore disease, caused by a bacterium called milky spore, Paenibacillus (formerly Bacillus) popilliae.

Biological controls like milky spore disease, which is specific for the control of Japanese beetles, are advocated for control of grubs, rather than chemicals.
