  • Patent number: 5432148
    Abstract: This invention provides a fungicide composition which is capable of in situ generation of ammonium bicarbonate when applied to plant foliage in the form of an aqueous dispersion. The constituents include (1) an ingredient such as urea which slow-releases ammonia under aqueous alkaline pH conditions; and (2) an alkali metal bicarbonate ingredient which imparts alkalinity to the aqueous dispersion, and provides bicarbonate ions for combination with the released ammonium ions. A spreader-sticker ingredient is included to maintain the ingredients in contact with plant foliage over an extended period after application.
    Type: Grant

  • Patent number: 5432146
    Abstract: The present invention provides a fungicidal fertilizer composition which contains ingredients which are biocompatible for purposes of agricultural applications, and which are harmless to animals and humans. An invention fungicide composition in the form of a dry blend formulation remains non-caking and free-flowing under storage conditions. Illustrative of an invention fungicide composition is a formulation which has a content of sodium bicarbonate, potassium bicarbonate, potassium oleate, xanthan gum and a fertilizer-effective content of nitrogen, phosphorus and potassium elements. The combination of potassium oleate and xanthan gum functions as an effective spreader-sticker and film-forming medium when the composition is diluted with water for agricultural applications. When the aqueous medium is hard water, calcium oleate is formed which enhances the sticker properties of the aqueous fungicide composition in agricultural applications.
