摘要:
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° C. or a Gardner color value less than 10.

摘要:
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.
摘要:
There is provided a concentrate herbicidal composition comprising a first herbicide selected from glyphosate and glufosinate, a second herbicide that is a chloroacetamide, e.g., acetochlor or metolachlor, and a third herbicide that is a triazine, e.g., atrazine, wherein the composition is a suspoemulsion having an aqueous phase, an oil phase, and particles dispersed in the aqueous and/or oil phases, and is stabilized by a stabilizing amount of one or more emulsifiers. Also provided is a method of use of a composition of the invention for killing or controlling weeds in a field.
摘要:
An emulsifiable pesticidal suspension concentrate composition is provided comprising (a) a pesticidally effective amount of a liquid pesticide of low solubility in water, for example a chloroacetamide herbicide such as acetochlor, (b) a pesticidally effective amount of a solid particulate pesticide, more particularly a salt-forming pesticide, for example a glyphosate herbicide, in solid particulate form, dispersed in the liquid pesticide, (c) a stabilizing amount of a suspension aid, (d) an emulsifying agent in an amount sufficient to emulsify the concentrate composition in a suitable volume of water to form a dilute sprayable composition, and (e) zero to an assay adjusting amount of an inert liquid in which the liquid pesticide is soluble or miscible. The concentrate composition is substantially non-aqueous. The liquid and solid pesticides are selected to be chemically compatible with each other. By substantial elimination of water and inert organic solvents according to the invention, suspension concentrate compositions can be provided having a very high concentration of active ingredients.
