Carboxamides (i.e., R-c(=o)nh2, Wherein R Is Hydrogen Or Carbon, And Substitution May Be Made For The Hydrogens On The Nitrogen Only; E.g., Dichloracetamides, Etc.) Patents (Class 504/112)
  • Patent number: 5484760
    Abstract: The disclosure herein relates to means for combatting the adverse phytotoxic action to crops arising from the interaction of various herbicidal compounds and biocidal compounds, e.g., insecticidal and/or fungicidal compounds. The means employed to reduce said interaction involves the safening action of various antidotal compounds.

  • Patent number: 5223477
    Abstract: Microcapsule formulations are combined with emulsions or particle dispersions in a single-package formulation which is storage-stable and provides substantially the full efficacy of each of the two forms as if applied individually. The single-package formulation is suspension having two dispersed phases--the first being an active species encapsulated in a shell of inert polymeric diffusion-limiting material (i.e., a microcapsule), and the second being an active species in water-insoluble form with no diffusion-limiting barrier at its surface. An appropriate suspension system is included to prevent the dispersed phases from agglomerating within themselves and with each other. The invention is useful in combining two different active ingredients as well as in combining immediate-delivery and delayed-delivery forms of the same active ingredient.
