Biological controls use living agents to control pests. Although the term can technically refer any organism that kills pests, it most often refers to products containing microscopic organisms (usually bacteria or fungi) that we apply to plants. Larger predators of garden pests, such as ladybugs and toads, are usually called "beneficials" and are addressed in the following section, "The Benefits of Beneficials."
Most organic gardeners are familiar with Bt (short for Bacillus thuringiensis), a strain of bacteria used to control pest caterpillars. Other biological controls include milky spore disease and parasitic nematodes, both of which are used to control Japanese beetle grubs. Some of the biggest innovations in pest control are coming in the field of biological controls. Manufacturers have introduced products containing Streptomyces griseoviridis, a species of soil bacteria that colonizes roots and helps prevent disease organisms from infecting the plants. In light of recent bans on common synthetic pesticides, we're likely to see more and more biologically based pesticides introduced.
