  • Patent number: 8298992
    Abstract: A composition includes an agricultural component in an amount of at least about 27% by weight and a solvent composition in an amount not greater than about 55% by weight. The solvent composition includes an amide having a structure of Formula I: wherein R1 comprises a C3 to C15 hydrocarbon group, and wherein R2 and R3 comprise a C1 or higher hydrocarbon group.
    Type: Grant

  • Publication number: 20080020933
    Abstract: In agricultural practice it is known to use emulsifiable oils (commonly referred to a Crop Oil Concentrates, COC) as bioefficacy enhancers for pesticides, especially herbicides. Cationic surfactants are widely known to be particularly effective bio-active enhancers for herbicides, especially for glyphosate-type herbicides. The present invention includes two novel aspects: 1) While the vast majority of COCs are petroleum-based paraffinic oils or esterified seed oils, this invention embodies a new oil phase, a hydrocarbon oil such exemplified by EXXON-MOBILS D-130, which when combined with the surfactants described herein, exhibits surprising enhancement of herbicidal activity in field tests; and 2) COC's are designed to form stable emulsions in water The combination of cationic surfactants and phosphate esters in this invention not only form very stable emulsions in water, but, surprisingly, also form extremely stable emulsions in concentrated liquid fertilizers, including 32-0-0 fertilizer.
