Abstract: Hydrogen cyanamide (HyCyn) is a product derived from calcium cyanamide. Three decades ago HyCyn became commercially available as a plant growth regulator. Sprayed on dormant plants, it provides uniform bud-break. This present invention provides repeatable methods for using aqueous HyCyn, and other similar water-soluble low molecular weight cyanamide or nitrile containing compounds, as stand-alone biocides. Qualities include: safer delivery to field settings, fewer environmental impacts and predictable plant growth improvement. HyCyn with its systemic qualities can act as a fertilizer, desiccant, nematicide, fungicide, herbicide, growth regulator and an agent of enzyme inactivation. These biocidal and other effects appear to be a result of double or triple bonds connecting carbon with nitrogen, and therefore it is expected that other water-soluble low molecular weight compounds having carbon-nitrogen double or triple bonds can act similarly.

Abstract: Agricultural crops are protected from the growth of weeds and other undesirable organisms by the application of hydrogen cyanamide in a granular formulation.

Abstract: An aqueous storage-stable composition comprises from about 10 to about 35% by weight hydrogen cyanamide, from about 3 to about 25% by weight propionic acid, potassium propionate or ammonium propionate, and water, and has a pH of from about 2.5 to about 4, wherein the concentration of hydrogen cyanamide is greater than the concentration of propionic acid.

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 acid, with improved pesticidal effect.

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.
