Herbicidal compositions are provided which cause rapid symptomology while delivering long term control of regrowth of plants. The herbicidal concentrate compositions comprise N-phosphonomethylglycine or a herbicidal derivative thereof, an auxin herbicide or a herbicidal derivative thereof, and at least one surfactant. Also provided is a method for killing or controlling the growth of certain plants by contacting the foliage of the plants with the diluted concentrate composition.

Herbicidal compositions containing N-phosphonomethyl glycine and an auxin herbicide

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

Solid and liquid pesticidal concentrate and spray compositions are described which exhibit enhanced efficacy due to the addition thereto of a compound which increases EPSPS enzyme inhibition by the pesticide, cell membrane permeability, or expression of hydroxyproline-rich glycoproteins.

Pesticide compositions containing dicarboxylic acids

Pesticidal concentrate and spray compositions are described which exhibit enhanced efficacy due to the addition thereto of a compound which increases cell membrane permeability, suppresses oxidative burst, or increases expression of hydroxyproline-rich glycoproteins.

Pesticide compositions containing oxalic acid

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

Potassium glyphosate formulations

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.

A composition is disclosed for application to a plant that comprises an exogenous chemical (for example, a postemergent herbicide), an aqueous diluent, and a first excipient substance that is amphiphilic.

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.
