Abstract: Disclosed are compositions that include treated biodiesel glycerin. The disclosed compositions may be utilized as soil-amendments for controlling pests, weeds and for enhancing growth of plants. The biodiesel glycerin utilized in the disclosed compositions may be treated by one or more steps including neutralization, heating, refluxing, condensing, and distilling.

Abstract: A method of controlling the plant back interval after application of sodium azide. The plant back interval can be significantly shortened by application of a dithiocarbamate, a thiocarbamate, a carbamate, an organic sulfide, an organic disulfide, or an aldehyde, with which the sodium azide may react and become inactivated. These compounds may be applied to soil to deactivate sodium or potassium azide residues and thus allow for immediate planting of a desirable turf or crop, and prevent plant stunting and delayed fruiting of crops without adversely affecting plant growth. The present invention thus provides a method for manipulating the activity period of sodium azide against pests by stopping its activity, when desired, by the application of one or more of these deactivating compounds. The preferred compound is metam sodium which is a dithiocarbamate.

Abstract: Agricultural crops are protected from the growth of undesirable vegetation as well as nematode and insect infestations, by the application of hydrogen cyanamide in combination with a short-chain, water-soluble monocarboxylic or polycarboxylic acid, the acid containing 1-3 carboxy groups and either no hydroxy groups or 1-3 hydroxy groups.

Abstract: A method for controlling pests and weeds on or around plants, especially crop plants. The method includes admixing 2-propenal or other related enal compounds to form an aqueous solution, and applying the aqueous solution to plants, plant seeds, weeds, or soil around the around the area in which the plants grow. The aqueous solution contains about 1 to about 1350 parts of the active compound per million parts of water, and is applied to the soil in amounts of from about 75 pounds to about 800 pounds of active compound per acre of soil. At lower application rates of from about 1 pound to about 100 pounds of the active compound per acre of soil, 2-propanol and related enal compounds have the beneficial effect of enhancing the growth of the plants. In addition, application of these enal compounds also helps in reducing transplant shock of tomato plants.

Abstract: Disclosed is both a method and composition for controlling deleterious organisms, such as insects, nematodes and weeds by applying a compound comprised of a liquid medium comprising azide and amine. The azide can be selected from the group consisting of sodium azide and potassium azide or a combination of the two. The composition provides an effective pesticide, without causing significant harm to the environment. The composition may be applied to soil to control a population of a deleterious organism.

Abstract: Disclosed is both a method and composition for controlling deleterious organisms, such as insects, nematodes and weeds by applying a compound comprised of a liquid medium comprising an azide and an azide stabilizer. The azide can be selected from the group consisting of sodium azide and potassium azide or a combination of the two. The composition provides an effective pesticide, without causing significant harm to the environment. The composition may be applied to soil to control a population of a deleterious organism.

Abstract: Disclosed is both a method and composition for controlling deleterious organisms, such as insects, nematodes and weeds while maintaining beneficial soil organisms, by applying a compound comprised of a liquid medium and comprising an azide and an amino acid polymer. The azide can be selected from the group consisting of sodium azide and potassium azide or a combination of the two. The composition provides an effective pesticide, without causing significant harm to the environment. The composition may be applied to soil to control a population of a deleterious organism.

Abstract: Chemical compositions having superior nematicidal properties are formulated. The compositions contain one or more selected aldehydes as the major component and one or more aliphatic or cyclic isothiocyanates as a minor component. Preferred mixtures contain furfural and one or both of methyl isothiocyanate and allyl isothiocyanate. Plant-parasitic nematodes are controlled by contacting the nematodes with the nematicidal compositions, by, for example, applying the compositions to soil or other plant growth media containing the nematodes.

Abstract: The invention accelerates the growth of all types of plants, i.e. tomato, cucumber, bell pepper, tobacco, horticultural crops, and others, and increases plant health. The invention is designed to increase the rate of seedling growth in the soil or in the greenhouse; and produce seeds having a coating imparting resistance to disease, thereby decreasing the time required to produce transplants in seedling greenhouses prior to transplanting into agricultural fields; and develop “disease-suppressive” transplant plugs, which are protected for a time from multiple diseases through combined mechanisms of stimulated plant defense and increased activity of indigenous antagonistic microorganisms on plant roots. Compositions and methods of use are provided.
