I. Background
[0001] High strength formulations, for example, high concentration or high load, are desirable for a variety of economic and environmental reasons, including reduced shipping and handling costs. Liquid premix concentrates containing two or more active ingredients are useful in a wide variety of agricultural applications. For example, two or more active pesticidal ingredients can be combined to control a broader spectrum of pests, or to use multiple modes of action, compared to the individual active ingredients alone.
[0002] Normally, water-insoluble active pesticidal ingredients are formulated in water with water-soluble pesticides as aqueous suspension concentrates (SC) or by dissolving water-insoluble pesticide in an organic solvent and forming an oil-in-water emulsion. water (EW). The preparation of these liquid premix concentrates can be challenging due to chemical and / or physical instability. Examples of physical instability with these compositions include, for example, phase separation, crystallization, deposition, sedimentation, gelation and agglomeration.
[0003] Water-soluble pesticide salts, for example, glyphosate salts, when dissolved in water form high ionic resistance solutions which then combined with organic solutions containing oil-soluble pesticides usually form oil-in-water emulsions. These concentrated, pre-mixed compositions, however, can be difficult to stabilize due to the high ionic resistance of the aqueous phase and require the proper choice of surfactants and / or additional inert ingredients. Previous efforts to combine oil-soluble herbicides with aqueous solutions containing glyphosate salts in a concentrated liquid formulation have been shown, for example, in US 6 713 433 B2, US 6 689 719 and US 6 369 001.
[0004] Previous efforts to prepare homogeneous, stable herbicide compositions containing water-soluble salts of carboxylic acid herbicides and water-insoluble herbicides have been severely limited in the choice, physical properties and / or load of the water-insoluble herbicide. II. summary

I. Examples
[00065] The following examples are presented to illustrate various aspects of the compositions described herein and should not be construed as limitations on the claims. Example 1: aqueous 2,4-D choline salt concentrate
[00066] A concentrated aqueous solution of 2,4-D choline salt was prepared by reacting technical 2,4-D acid with an equimolar amount of choline hydroxide in water at room temperature. Additional water was then added, if necessary, to achieve the target acid concentration (ae) of 2,4-D at 45.7% by weight. Example 2: 2,4-D dimethyl ammonium salt concentrate (2,4-D DMA)
[00067] A concentrated aqueous solution of 2,4-D DMA salt was prepared by reacting technical 2,4-D acid with an equimolar amount of aqueous solution of dimethyl amine (40% by weight) in water at room temperature . Additional water was then added, if necessary, to achieve a target acid concentration (ae) of 2,4-D of 55.3% by weight. Example 3: aqueous 2,4-D herbicidal compositions and a second liquid herbicide, haloxifop-P-methyl ester
[00068] Examples 3 to 6 were prepared by adding haloxifop-P-methyl ester, optionally dissolved in Genagen 4166, to an aqueous 2,4-D DMA concentrate to provide the compositions described in Table 1 below. Transparent and homogeneous aqueous compositions were formed by mixing the samples through manual agitation. No crystal formation / growth or phase separation was observed with any of the samples after: (1) 2 weeks of storage in freeze / thaw conditions (F / T) (-10 degrees Celsius / 40 degrees Celsius cycle every 24 hours) hours), and (2) 2 weeks of storage at 0 degrees Celsius. The melting point of each sample was less than -15 degrees Celsius according to differential scanning calorimetry (DSC) measurement. Dilution of a 1% sample of each sample in spout water resulted in an opaque oil-in-water emulsion. Table 1. Concentrated compositions containing 2,4-D DMA and Haloxi-
