Abstract: A storage and shipping system for glyphosate herbicide is provided, comprising a container having a capacity of about 0.1 to about 100,000 liters or more, substantially filled with an aqueous solution of glyphosate, predominantly in the form of one or a mixture of the potassium and monoethanolammonium salts thereof, the solution having a glyphosate acid equivalent concentration of at least about 30 percent by weight. The storage and shipping system, by virtue of the relatively high specific gravity of the glyphosate salt solution, holds a greater weight of glyphosate than a system comprising an identical container substantially filled with an aqueous solution of the isopropylammonium salt of glyphosate at the same glyphosate concentration by weight. Alternatively, the container of the storage and shipping system can be smaller than that of a container holding the same weight of glyphosate in the form of the isopropylammonium salt.

Abstract: A herbicidal composition is provided comprising an aqueous solution of N-phosphonomethylglycine, predominantly in the form of the monoethanolammonium salt thereof, at a concentration of about 30% to about 48% N-phosphonomethylglycine acid equivalent by weight. In a particular embodiment, a herbicidal composition comprises water; N-phosphonomethylglycine predominantly in the form of the monoethanolammonium salt thereof in solution in the water in an amount of about 360 to about 570 g a.e./l of the composition; and a surfactant component in solution or stable dispersion in the water, comprising one or more surfactants in a total amount of about 20 to about 200 g/l of the composition, this surfactant component being selected such that the composition has a cloud point not lower than about 50° C.

Abstract: This invention relates to dry, water soluble, agriculturally acceptable herbicidal compositions, to a herbicidal method of use thereof and and to a process for preparing such compositions.

Abstract: 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.

Abstract: A novel method is provided wherein plants are first treated with an exogenous chemical (e.g., glyphosate herbicide) and then sequentially treated with a liquid accession agent which provides improved biological (e.g., herbicidal) effectiveness such that plants are controlled with lower rates of the applied exogenous chemical (e.g., glyphosate herbicide). Sequential application has been demonstrated to reduce the antagonism to herbicidal effectiveness that can be exhibited when the accession agent is added to a herbicide in a tank mix or simple coformulation. Typical accession agents employed in the disclosed method include a class of surfactants known as superwetting agents, such as certain organosilicone-based and fluorocarbon-based surfactants.
