A herbicidal composition is provided comprising an aqueous solution of N-phosphonomethylglycine, predominantly in the form of the potassium salt thereof, at a concentration of at least 300 g a.e./l of the composition; and a surfactant component in solution or stable suspension, emulsion, or dispersion in the water, comprising one or more surfactants in a total amount of about 20 to about 300 g/l of the composition, wherein the composition has a viscosity of less than about 250 centipoise at 0&#xb0; C. or a Gardner color value less than 10.

Surfactants and formulations

Aqueous pesticidial concentrate emulsions or microemulsions are described which are storage stable after exposure to temperatures ranging from 60&#xb0; C. to &#x2212;20&#xb0; C.

Stable liquid pesticide compositions

Composition and method for treating plants with exogenous chemicals

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.

Plant treatment compositions having enhanced biological effectiveness

Concentrate composition of plant treatment compound in acid form

Compositions of exogenous chemicals, particularly phloem-mobile exogenous chemicals, are provided for treatment of plants, wherein the composition comprises the exogenous chemical and an enhancing agent consisting of an anthraquinone or substituted anthraquinone. Specific compositions contain herbicides, particularly N-phosphonomethylglycine and herbicidal derivatives thereof, i.e., glyphosate. The compositions exhibit enhanced effectiveness compared to compositions in which the enhancing agent is not present. Also provided are processes for applying an exogenous chemical with an anthraquinone or substituted anthraquinone enhancing agent to achieve enhanced biological effectiveness.

A plant treatment composition for application of an anionic exogenous chemical substance such as glyphosate herbicide to foliage of a plant is provided. The composition is a colloidal dispersion having supramolecular aggregates dispersed in an aqueous application medium. The supramolecular aggregates comprise one or more amphiphilic salt(s) having anions of the exogenous chemical substance and cations derived by protonation of one or more polyamine(s) or polyamine derivative(s) each having (a) at least two nitrogen-containing groups, of which a number n not less than 1 are amino groups that can be protonated to form cationic primary, secondary or tertiary ammonium groups, and (b) at least one hydrocarbyl or acyl group having about 6 to about 30 carbon atoms. The composition contains (i) a molar amount X in total of the exogenous chemical substance, in all salt and acid forms thereof present, sufficient to elicit a biological response when the composition is applied to the foliage of the plant at a rate of about 10 to about 1000 l/ha, (ii) a molar amount A in total of said polyamine(s) and derivative(s) thereof and cations derived therefrom, and (iii) a zero or molar amount B in total of one or more monovalent base(s) and cations derived therefrom, said base(s) being other than a polyamine or derivative thereof, such that nA/(nA+B) is about 0.01 to 1, and (nA+B)/X is about 0.5 to about 10. Also provided are a liquid concentrate composition which, upon dilution with water, forms a plant treatment composition as described above, and a process for making such a liquid concentrate composition. Plant treatment compositions of the invention are useful for eliciting a biological activity, for example herbicidal activity, in a plant when applied to foliage thereof.

Process and compositions promoting biological effectiveness of exogenous

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

A process is provided for enhancing the reliability and consistency of effectiveness of an exogenous chemical substance applied to foliage of a plant, involving application of a phenyl-substituted olefin compound to the foliage, either sequentially or simultaneously with the exogenous chemical substance. Also provided are plant treatment and concentrate compositions comprising an exogenous chemical substance and a phenyl-substituted olefin compound.

Process and compositions for enhancing reliability of exogenous chemical

Solid N-phosphonomethylglycine or glyphosate acid is charged to a substantially closed system and then partially pre-dried as by continuously recirculating it through a hot air grinding/drying system. A cooled solution of ammonium hydroxide is then metered into and reacted with the partially dried glyphosate acid as it is being recirculated in a manner such that the moisture content of the reaction mass so formed is continuously decreased throughout the reaction. Following completion of the ammonium hydroxide addition, a powdered reaction mass/product having a moisture content of about 2 wt. % is formed. Significantly, at this stage, the ammonium glyphosate product is suitable for end use and it can be readily dissolved in water and immediately used as a herbicide or plant growth regulator. More importantly, however, this product is capable due to its highly sorptive character to be further formulated into a product exceptionally highly loaded with adjuvants and particularly surfactants.
