  • Patent number: 7399730
    Abstract: Improved plant growth is realized especially with turf grasses by using an enhanced plant growth medium prepared by adding a bioefficacious amount of C1-C4 alkyl ether of methyl oxirane-oxirane copolymer that, serendipitously reduces the water repellency of the medium.

  • Patent number: 6200961
    Abstract: A low volatile organic compound co-solvent system is disclosed for preparing emulsion concentrates of low melting organophosphorous insecticides wherein the bioefficacy of the insecticide active is significantly enhanced. The co-solvent system comprises a water-soluble ethoxylated fatty acid/rosin acid-nonionic surfactant composition.

  • Patent number: 6039966
    Abstract: A low volatile organic compound co-solvent system is disclosed for preparing emulsion concentrates of water-insoluble pesticides having a melting point of less than about 110.degree. C. The co-solvent system comprises a water-soluble ethoxylated fatty acid/rosin acid-nonionic surfactant composition.
    Type: Grant

  • Patent number: 5738623
    Abstract: This invention relates to the use of activated charcoal granule compositions which, when dry spread and "watered-in" to a site, reduces undesirable biological activity of deleterious organic compounds. When wet, these granules disperse very rapidly with a large dispersion area to original granule diameter ratio. The granules have high loadings of charcoal, i.e., from about 60 to about 95 weight percent and contain from about 5 to about 40 weight percent of a surfactant system which exhibits excellent dispersing; rewetting; and binding properties.
