Embodiment 1

[0163]Some forms of 2,4-D are prepared by adding an amine (ethylenediamine or 3-(dimethylamino)-1-propylamine (DMAPA)) to water, followed by the addition of 2,4-D acid with stirring until dissolved. A series of solutions of the amine salt resulted in formulations 10047643-1, 10047643-2, 10047643-3. Tables A1-A3 provide the compositional details of each formulation.

Embodiment 2

[0171] The formulations in Table B1 were prepared as follows. Add DMAPA to the Erlenmeyer flask and stir. Add 6 grams of glyphosate wet cake while stirring, then add 10 grams of water and heat up to 55°C. A further 75 grams of glyphosate wet cake was added to the stirred solution. The resulting solution thickened and was heated to 85°C for 10 minutes. Then 10 grams of water were added and the solution was heated to 98°C. More glyphosate wet cake was then added, totaling 112 grams, and the solution was stirred for a further 15 minutes at 95°C. The remaining water, totaling 54.8 grams, was added to the resulting unclear solution, which was heated at 100°C. After 10 minutes, a clear yellow solution was obtained which was allowed to cool and poured through a 50 mesh screen and stored in a glass bottle. Using a similar procedure, various formulations were prepared at target loadings of 606 g / l a.e., 620 g / l a.e., 607 g / l a.e. and 584 g / l a.e. Table B2 provides the composition...

Embodiment 3

[0178] A series of premixes of 2,4-D DMAPA and glyphosate DMAPA salts were prepared as follows. Add DMAPA to the water, then add 2,4-D with stirring until dissolved. Then add the glyphosate wet cake and continue stirring until dissolved. ETHOQUAD C12 75DEG was then added and the solution was stirred for half an hour. Tables B3-B5 provide the compositional details of each formulation. In addition, Tables B6-B8 provide similarly prepared formulations additionally containing an oil-based drift reducing or retarding agent (DRA).

Abstract

Herbicidal compositions such as aqueous herbicidal concentrate compositions and application mixtures are described. In particular, the present invention relates to various aqueous herbicidal compositions comprising a combination of acidic herbicides formulated as certain amine salts. The invention also relates to various methods of making and using these herbicidal compositions.

Description

technical field [0001] The present invention relates generally to herbicidal compositions such as aqueous herbicidal concentrate compositions and herbicidal application mixtures. In particular, the present invention relates to various aqueous herbicidal compositions comprising combinations of acidic herbicides formulated as certain amine salts. The invention also relates to various methods of making and using these herbicidal compositions. Background technique [0002] In order to increase the efficiency of applying herbicidal active ingredients, it is highly desirable to combine two or more active ingredients in a single formulation. Application of combinations of active ingredients with different herbicidal modes of action may provide better weed control. In addition, concentrated compositions containing a high loading of active ingredient are more economical to transport and store. Concentrated compositions containing high loadings of multiple active ingredients (ie, p...
