Abstract: The entomopathogenic fungus Paecilomyces fumosoroseus and certain related species, such as P. javanicus are useful for controlling infestations by subterranean termites, particularly those belonging to the family Rhinotermitidae. The family Rhinotermitidae includes two species of subterranean termites having extremely high economic importance in the United States; namely the Formosan subterranean termite (Coptotermes formosanus Shiraki), and the native (North American) subterranean termite (Reticulitermes flavipes). Large numbers of infectious propagules of the fungus, such as blastospores and conidia can be readily cultured on media that are easily and inexpensively prepared and incorporated into formulations for controlling termites. These fungi are useful for protecting living trees, plants, wood, wood structures, and other cellulosic materials susceptible to termite infestation and damage.

Abstract: A stabilized, granular, biocontrol agent formulation for agricultural pests relies upon a combination of a water absorbent material, a membrane stabilization agent, and a granulating agent to achieve the desired stability and free-flowing properties. The granular product is easily prepared by simple mixing and can be readily rehydrated into a sprayable composition.

Abstract: Granules of encapsulated living organisms for controlling agricultural pests are provided having a coating of an invert oil that forms a water-in-oil emulsion and an adsorbent for the oil to make the coated granules free-flowing. The oil slows drying of the organisms to maintain vitality of the organisms. The coated granules are produced by encapsulating bacteria, fungi or nematodes that control agricultural pests in alginate, starch or wheat gluten to form granules, coating the granules with a water-in-oil emulsion of the invert oil, coating the granules with the adsorbent for the oil and drying the coated granules to about 1-10% moisture. The adsorbent can be hydrated silica, fumed silica, clay, bran, diatomaceous earth, zeolite, absorbent starch or mixtures thereof.

Abstract: Weed pathogenic fungi to be encapsulated in a wheat gluten matrix are blended with flour and water to make a cohesive dough. The dough is extruded, rolled out into a sheet, or otherwise shaped, and dried to form products that contain the fungi entrapped throughout the gluten matrix. The encapsulated fungi grow onto the surface of said products when provided with sufficient light and water. The products of this invention may be used to infect and kill weeds.

Abstract: This invention relates to a method for preparing pellets containing living biocontrol fungi. Fungi are selected and grown for sufficient time to produce inoculum. The fungal propagules are harvested, homogenized and diluted with sodium alginate solution. Pelletization is then accomplished by dropwise addition of the fungal propagule-alginate mixture into a solution of calcium chloride or calcium gluconate. The resultant alginate gel pellets containing living fungi can then be dried and are used to inoculate agricultural fields infested with soilborne plant diseases.

Abstract: This invention relates to alginate gel pellets containing living fungus capable of producing conidia when exposed to sufficient light and moisture. Fungi are selected and grown for sufficient time to produce inoculum. The fungus cultures are harvested and homogenized for approximately 30 seconds and diluted to a ratio of about 1:3 (v/v) with 1.33% (w/v) sodium alginate in distilled water producing a final concentration of 1.0% sodium alginate and pH of 6.6 to 7.3. Pelletization is then accomplished by dropwise addition into 0.25 M CaCl.sub.2 in water. The resultant alginate gel pellets of approximately 3 to 5 mm in diameter can then be dried and used to inoculate agriculture fields to kill selected weeds.

Abstract: This invention relates to a method for preparing pellets containing living biocontrol fungi and nutrient dispersed throughout. Living fungi are selected and grown for inoculum. The fungal propagules and wheat bran are added to a sodium alginate solution. The fungal propagule-alginate-bran mixture is added dropwise into a solution of calcium chloride. The resultant alginate gel pellets containing living fungi can be dried and used to inoculate agricultural fields infested with soilborne diseases.

Abstract: Alginate gel beads containing bioactive materials dispersed therein are the product and the process of this invention. These beads can be made to either float or sink in aqueous environments, and are capable of providing the controlled release of their bioactive materials when applied to terrestrial or aqueous environments.
