  • Patent number: 9433208
    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-MOBIL'S 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.

  • Patent number: 8288317
    Abstract: An agrochemical composition includes a homogeneous single-phase liquid crystal in thermodynamic equilibrium. The agrochemical composition can be a surfactant composition or a pesticide composition. The surfactant composition is a blend of surfactants, whereas a pesticide composition has an active ingredient and one or more surfactant adjuvants. A pesticide composition, or a surfactant composition in combination with an active ingredient, may be used to control pests.

  • Publication number: 20040142823
    Abstract: The present invention provides agricultural surfactant adjuvants that enhance the bioefficacy of herbicides and other pesticides. Also provided are agriculturally-valuable compositions containing such surfactant adjuvants. One advantage to an adjuvant composition according to the invention is combined high efficacy and low toxicity, including low eye and skin irritancy and low aquatic toxicity. Sequesterant agents can also be added to condition calcium or other interfering ions or species present in spray water.

  • Publication number: 20020160918
    Abstract: Disclosed herein are surfactants useful for improving the bioefficacy of herbicides. A surfactant according to the invention may comprise: (i) phosphate monoesters of tallow amine ethoxylates, alone or in combination with phosphate diesters of tallow amine ethoxylates, or (ii) alkoxylated phosphate monoesters of tallow amine ethoxylates, alone or in combination with alkoxylated phosphate diesters of tallow amine ethoxylates. The present invention also provides for herbicide compositions that contain the surfactants of the present invention. The herbicide compositions comprise a herbicidal active ingredient, a surfactant of the present invention, and optionally, one or more formulation aids. The herbicide compositions of the present invention unexpectedly have a reduced tendency to cause eye and skin irritation. The present invention additionally provides for a method of controlling unwanted weeds or vegetation using the herbicide compositions of the present invention.

  • Patent number: 5616811
    Abstract: Etheramine alkoxylates are described which have the formula: ##STR1## where R.sup.1 is a straight or branched alkyl, aryl or alkylaryl group of 6 to 22 carbon atoms; R.sup.3 are independently hydrogen or C.sub.1 to C.sub.3 alkyl; m averages from about 1 to about 20; and x and y each independently average from about 0 to 30, where x+y averages from about 2 to about 60. These etheramine alkoxylates have surfactant properties. Further, they may be quaternized to make other compounds which will have useful surfactant properties.
