  • Patent number: 6479434
    Abstract: Methods and compositions are disclosed wherein exogenous chemicals are applied to plants to generate a desired biological response. One embodiment of the present invention is a plant treatment composition that comprises (a) an exogenous chemical; (b) a first excipient substance which is a compound or mixture of compounds having the formula R14—CO—A—R15 wherein R14 is a hydrocarbyl group having about 5 to about 21 carbon atoms, R15 is a hydrocarbyl group having 1 to about 14 carbon atoms, the total number of carbon atoms in R14 and R15 is about 11 to about 27, and A is O or NH; and (c) a second excipient substance which is an amphiphilic substance having a critical packing parameter greater than ⅓.

  • Patent number: 6475953
    Abstract: A composition is disclosed for application to a plant that comprises glyphosate, an aqueous diluent, and an excipient substance that is amphiphilic. The weight/weight ratio of the excipient substance to the exogenous chemical is between about 1:3 and about 1:100. The aqueous composition forms anisotropic aggregates on a wax layer, and the presence of the anisotropic aggregates can be detected by a test described herein. Compositions of the present invention, when applied to plants, provide enhanced biological activity per unit amount of glyphosate, as compared to otherwise similar compositions containing surfactants that do not form anisotropic aggregates. Without being bound by theory, it is presently believed that this enhanced biological activity results from the formation or enlargement of hydrophilic channels through the epicuticular wax of the plant.
