  • Patent number: 5425952
    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.

  • Patent number: 5422126
    Abstract: A method for providing aqueous solutions of HOBr or HOCl which includes adding bleach (NaOCl) to a solution of HBr or HCl until an identified absorbance or color change in the resulting solution is detected. Dialkylhydantoins are optionally added to the resulting solution to suppress the formation of halate ions. The method provides a simple and reliable method for producing accurately defined solutions of hypohalous acids, which are useful in a variety of ways, including for disinfecting, cleaning, and odor control purposes.

  • Patent number: 5417987
    Abstract: A method for enhancing the effect of a toxicant such as chlorine or potassium on bivalve molluscs such as zebra mussels. Application of serotonin or a serotonin agonist in low concentrations inhibits the mussels' ability to close their valves to protect themselves from the effect of any toxicants in the water. Thus administering serotonin or a serotonin agonist for a period of time, followed by administering a toxicant, substantially enhances the effect of the toxicant on the zebra mussels. Thus less of the toxicant need be administered to control zebra mussels. The concentration of serotonin needed to enhance toxicant control of exotic zebra mussels has been found to be at or below the threshold of serotonin activity on native bivalves, at least those native to the lower Mississippi River. Furthermore, serotonin is naturally degraded rapidly by aquatic microorganisms.
