Lignin-based pest control formulations |
May 12, 1998 |
| The present invention provides pest control formulations which comprise lignin as well as methods of protecting pest control agents from environmental degradation through the use of lignin. A solubilized lignin solution is prepared by mixing water, lignin, and a pH adjuster to form a |

Device for controlling pests |
February 24, 1998 |
| The present invention is a device for delivering pesticide to pests, comprising (a) an outer layer comprising a porous water-insoluble polymeric; (b) an inner layer in contact with the outer layer, the inner layer comprising a water-soluble feeding stimulant and a carbohydrate which |

Adherent, autoencapsulating spray formulations of biocontrol agents |
October 29, 1991 |
| Sprayable, starch-based formulations for autoencapsulating biological control agents, such as pathogenic bacteria and viruses, incorporate a sugary material to promote adherence of the encapsulated agent to treated foliage. The autoencapsulated pathogens are characterized by high sur |

Starch encapsulation of entomopathogens |
August 22, 1989 |
| Biological control agents such as pathogenic bacteria and viruses have been encapsulated in a protective, starch matrix without the use of chemical crosslinking agents. The agent is blended into a dispersion of pregelatinized starch, which is thereafter subjected to conditions suitab |

Encapsulation by entrapment within polyhydroxy polymer borates |
March 27, 1984 |
| Chemical biological agents to be encapsulated are dissolved or dispersed in an aqueous paste of a gel-forming polyhydroxy polymer. Subsequent addition of boric acid or a boric acid derivative at an alkaline pH converts the paste into a gel, thereby entrapping the agents in a protective m |

Encapsulation by entrapment within starch adduct matrix |
May 10, 1983 |
| Water-insoluble chemical biological agents to be encapsulated are dispersed in an aqueous paste of a starch-containing material alkoxide. Subsequent addition of selected water-soluble alkali earth metal cations insolubilize the paste, thereby entrapping the agents in a protective matrix. |

Starch adduct encasement of particulate elastomers |
September 7, 1982 |
| Powdered and crumb rubber are prepared by dispersing in a starch alkoxide paste appropriately sized particles of wet curd from the precipitation of a latex emulsion, and then insolubilizing the paste by treatment with select bivalent cations. The result is a starch adduct encasing the |

Encapsulation by entrapment |
August 17, 1982 |
| Chemical biological agents to be encapsulated are dissolved or dispersed in an aqueous solution of polyhydroxy polymer xanthate. Simultaneous addition of a strong acid and a coupling agent to the solution insolubilizes the polyhydroxy polymer without degrading the xanthate moiety, thereb |

Encapsulation by entrapment |
July 7, 1981 |
| Water-soluble and water-insoluble solid and liquid core materials are encapsulated by the same method. Core materials are simply entrapped in a matrix of water-insoluble polyhydroxy polymers which are insolubilized from their corresponding water-soluble xanthates in the presence of the |

Oxidation of thiols to disulfides |
August 2, 1977 |
| A simple and selective technique for the oxidation of thiols resulted in high yields of the corresponding disulfides. The reaction is tailored so that all byproducts are either volatile or insoluble and the end product recovered easily in essentially pure form.A nonexclusive, irrevocable |
