Corn rootworm infestations can be controlled by inoculating the soil with parasporal-inclusion forming species of Bacillus laterosporus to produce viable populations of that bacteria effective to reduce crop damage. Viable populations of B. laterosporus can be initiated by application to the soil, of effective amounts of vegetative cells or spores of the organism either in liquid suspensions, or as coatings on seeds or granular substrates.
