  • Patent number: 10709136
    Abstract: Introducing chlorine dioxide solution into an agricultural soil in an amount effective to suspend weed and pathogen growth in the soil. The chlorine dioxide is allowed to decompose in the soil. Then, a crop is planted in the treated soil. The decomposed chlorine dioxide provides nutrients for the crops as they grow.

  • Patent number: 8765656
    Abstract: Source water is treated by mixing a first component selected from the group comprising neutralized phosphonic acid compounds, neutralized phosphonate compounds, neutralized derivatives of phosphorus, neutralized anti-scalent polymers, and mixtures thereof, a second component from the group comprising chlorite salt and chlorate salt is admixed to the mixture of the water and the first component, and water. The water and the first and second components are present in amounts sufficient to form a stable liquid composition in which there is substantially no conversion of the second component to chlorine dioxide.

  • Patent number: 7771763
    Abstract: A chitosan polymer is added to an acid and water solution in an amount sufficient to form an edible composition having a solids content greater than five percent (5%) and a liquid viscosity. The composition is applied to food products, such as fruits, vegetables and nuts, to provide an edible protective coating for the food products. An edible wax emulsion and/or a preservative such as sodium benzoate, and/or an adhesion additive such as zinc acetate, and/or a wetting agent, and/or one or more additives from the group consisting of virgin and/or modified carbohydrates, proteins, hydrocolloides, lipids, oils, gums and waxes, natural and/or synthetic, may be added to the composition before it is applied to the food product.

  • Patent number: 7601266
    Abstract: A biofilm reducing agent (BRA) and a mineral deposit distorting agent (MDDA) are admixed to irrigation water in amounts sufficient to substantially eliminate biofilm formation in the emitters (14) of an irrigation system (10) and produce amorphous mineral deposits in the emitters that are easily washed away by the irrigation water as it flows through the emitters (14). The BRA may be an oxidizer selected from the group consisting of chlorine, ozone, chlorine dioxide, hydrogen peroxide, hydroxy peracitic acid, iodine, bromine, hydrogen dioxide, chlorate salts, chlorite salts and hypochlorite compounds and mixtures thereof. The MDDA is a phosphonate selected from the group comprising AMP, ATMP, HEDP, EDTMPA, HMDTMPA, DETPMPA, BHMPTMPA, PBTC, HPA, PCA, NTMP, and DTPMP.
