Abstract: A seed containing beneficial microorganisms, which, upon germination gives rise to a plant colonized by the microorganisms, and a method for producing the seed are provided. The seed is produced by adding the microorganisms to a biologically compatible liquid carrier to form a suspension of the microorganisms in the carrier, impregnating the seeds with the suspension, and removing the excess carrier from the seeds, whereby the viability of the microorganisms and the seeds is maintained. Plants colonized by beneficial microorganisms and methods of producing such plants are also disclosed.

Abstract: A continuous process for the separation of small particles from larger particles in a biological preparation passes a liquid stream of the preparation through a first filter or screen, which retains larger particles, passing smaller particles in the liquid. The large particles have retained on their surfaces wetting water, in which are entrained some of the small particles. The large particles are directed to a liquid having a concentration of smaller particles lower than the concentration of smaller particles in the wetting water, and mixed therein. The smaller particles separate from the larger particles in the mixed suspension, which is then directed to a second filter or screen, for further separation. The smaller particle/liquid stream may be recycled to the biological preparation stage, the liquid suspension for the large particles, or to a separator means where the smaller particles are separated off from the liquid stream.

Abstract: This invention discloses a new apparatus for the rearing of insects and the production of insect related products, primarily insect viruses and parasites commonly used for the control of insect pests. The apparatus comprises an environmental control system, a sealed enclosure consisting of a hood and a base, and a system of vertically or horizontally supported food leaves. Laminar air flow may be used. The method of use in producing insects, insect viruses, insect pathogens, and other insect products is also disclosed. Use of this apparatus and method affords savings in labor and supplies.

Abstract: A method for the production of a plant of reduced stature is provided comprising the introduction of a bacterial cell into a seed or a plant, the bacterial cell being capable of replicating in the plant and of inducing a reduction in plant stature. A seed and a plant modified by introduction of such a bacterial cell are also provided.
