  • Patent number: 8334002
    Abstract: The invention generally relates to mixtures of cinnamaldehyde (cinnamic aldehyde) and allicin (10%) in emulsifiable suspension formulations at ratios ranging from 1:1 to 20:1 for protecting plants from damage by nematodes, fungal pathogens, insects and mites. The nematicidal compositions described are easily flowable, easily mixable in water and have low volatility and exhibit no phytotoxicity. Methods of applying the compositions for agriculture use are disclosed.

  • Publication number: 20110229543
    Abstract: A method for controlling Dipteran larvae or a method for inhibiting the development of larvicidal resistance, controlling resistant populations and reducing resistance levels in Diptera by introducing a larvicidally-effective amount of a combination of a strain of Bacillus thuringiensis subspecies israelensis and a strain of Bacillus sphaericus into an environment containing Dipteran larvae; and a composition of the combination are disclosed. Preferably both strains are non-genetically modified.

  • Patent number: 6984609
    Abstract: A water-soluble granular composition including at least 40% of at least one plant growth regulator, at least one binder, at least one disaccharide and at least one surfactant; as well as methods for making and using the composition are disclosed. The water-soluble granular composition advantageously improves preparation of a solid plant growth regulator formulation for spray application, as such composition swiftly dissolves, is easily metered for application, can be more highly concentrated and is dust-free. A presently preferred water-soluble granular composition includes at least 40% of at least one gibberellin as the plant growth regulator.

  • Patent number: 5500403
    Abstract: Liquid formulations, suitable for use in extending the vase-life of cut flowers and which resist the development of unsightly discoloration and turbidity comprise from about 55 parts by weight to about 98 parts by weight of a sugar; from about 0.05 part by weight to about 1 part by weight of an inhibitor of aminocyclopropanecarboxylate synthase selected from L-trans-2-amino-4-(2-aminoethoxy)-3-butenoic acid and carboxymethoxylamine; from about 0.1 part by weight to about 5 parts by weight of an antimicrobial agent; from about 1 part by weight to about 5 parts by weight of aluminum sulfate; and from about 0.1 part by weight to about 5 parts by weight of a dicarboxylic acid of from two to six carbon atoms. All parts by weight based upon the total weight of the dissolved solid components.

  • Patent number: 5163993
    Abstract: A composition and method for thinning Perlette Seedless grape clusters is disclosed. The composition contains a surfactant and a gibberellin. In a method for thinning Perlette Seedless grape clusters, the composition is applied to Perlette Seedless grape clusters during bloom, with the result that clusters are produced that have fewer grapes and in which the grapes are increased in size and weight.

  • Patent number: 4224049
    Abstract: Compatibility agents were developed for improving the compatibility and stability of mixtures of liquid fertilizers and liquid or wettable powdered pesticides. These compatibility agents contain water, a low alkanol and an alkylaryl polyoxyethylene glycol phosphate ester. The compatibility agent is used at a preferred concentration range of 0.1 to 0.4% of the fertilizer solution. The preferred compatibility agent not only improves the compatibility of liquid fertilizer-pesticide mixtures, but also results in uniform and stable mixtures ensuring accurate pesticide applications. The preferred compatibility agent is a mixture containing about 16% water, about 20% methanol and about 64% of an octylphenol polyoxyethylene glycol phosphate ester.
