Description
.1 Formulations containing amino-/polyaminocarboxylates and organic phosphates, phosphonates or phosphites, and use thereof in agriculture Description 5 The present invention relates to the use of formulations comprising (A) one or more aminocarboxylates, selected from among methylglycine diacetate (MGDA) and its alkali metal salts, glutamic acid diacetate (GLDA) and its alkali metal salts, iminodisuccinate, hydroxyethylimine diacetate and ethyleneiminodisuccinate and the 10 corresponding alkali metal salts, (B) at least one organic compound selected from among organic phosphates, organic phosphonates and organic phosphites and salts of the abovementioned organic compounds, and (C) optionally water, 5 for application to plants or the ground. Furthermore, the present invention relates to formulations comprising (A) one or more aminocarboxylates, selected from among methylglycine diacetate (MGDA) and its alkali metal salts, glutamic acid diacetate (GLDA) and its alkali metal salts, 0 iminodisuccinate, hydroxyethylimine diacetate and ethyleneiminodisuccinate and the corresponding alkali metal salts, (B) at least one organic compound selected from among organic phosphates, organic phosphonates and organic phosphites and salts of the abovementioned organic compounds, and 5 (C) optionally water. Furthermore, the present invention relates to a process for the preparation of the formulations according to the invention. 0 It has long been desired to improve the yields of soils as regards fertility. In this context, it is not only the fertilization of the soil which plays a role, but also the control of undesired plants and animals capable of reducing a crop yield, A variety of organic phosphorus-comprising compounds, for example organic phosphates, 5 organic phosphonates and organic phosphites and salts of the abovementioned organic compounds, have a range of effects on organisms such as weeds, vermin and undesired fungi. A problem when applying many of these organic compounds is that they are capable of reacting with soil components such as iron oxides, aluminum oxides, layer silicates, calcium compounds and magnesium compounds and/or are capable of being adsorbed by the former, whereby they D are converted into a form which is insoluble in water and hence no longer available to plants. This process is also referred to as mineralization. Depending on the soil composition, mineralization takes place within a period of 2 to 14 days. Therefore, the activity is unsatisfactory despite the fact that the quantity available of organic phosphorus compounds is high or indeed too high. At the same time, the amount of active substances stored in the soil 2 and the environment is constantly being increased according to current practice, which is likewise undesired, A similar problem is that a mineralization of organic phosphorus-comprising compounds may 5 also be caused by the alkaline-earth metal ions which may be present in the water used for making dilute spray mixture. Depending on the water hardness and the degree of dilution, significant amounts of active substance may be eliminated in this manner. In many cases, therefore, glyphosate is applied to the soil together with considerable amounts of ammonium sulfate. In this context, the amounts of ammonium sulfate may be considerable. 10 Thus, EP 0 290 416 discloses a typical concentrate 74 g/l glyphosate (free acid), 49 g/Il glyphosate monoisopropylammonium salt, 120 g/I fatty amine ethoxylate and 280 g/l ammonium sulfate. Between 100 and 600 liters of formulation are typically employed per ha of field. This corresponds to an active substance discharge of 1-6 kg/ha field, The formulation comprises more ammonium sulfate than active substance. 15 It was therefore an object to provide formulations whose organic phosphorus compounds can be taken up readily by the soil or plants, for example in such a manner that an absorption capacity over a period of up to 8 weeks is ensured. It was therefore an object to provide uses of formulations by means of which organic phosphorus compounds can be taken up readily by .0 soils and in particular plants, It is furthermore an object to provide a method by means of which the organic phosphorus compounds can be made readily bioavailable. Accordingly, there have been found the uses and formulations defined at the outset. 5 According to the invention, there is used as least one formulation comprising (A) one or more aminocarboxylates, also termed aminocarboxylate (A) for short or else, summarily, compound (A), selected from among methylglycine diacetate (MGDA) and its alkali metal salts, glutamic acid diacetate (GLDA) and its alkali metal salts, iminodisuccinate, hydroxyethylimine diacetate and ethyleneiminodisuccinate and the 0 corresponding alkali metal salts (B) at least one organic compound, also termed compound (B), selected from among organic phosphates, organic phosphonates and organic phosphites and salts of the abovementioned organic compounds, and (C) optionally water, 5 for application to plants or the ground.

Studies on soil segments 11.1 Mineralization experiments, general protocol following the example SL.2 1 kg of loose sediment of ground earth from South Germany with a water content of 23%, a pH 5 of 6.1-6.3 and a mineral fraction of 45% (composition of the mineral fraction: 38% quartz, 20% carbonates, 20% mica, 9% clay mineral, 7% feldspar, 3% iron oxide; with an Al content of 1.7%, a Ca content of 1.4%, an Fe content of 2.1%, a phosphate content (determined as P 2 0 5 ) of 240 mg P 2 0 5 /kg soil) were placed in a round vessel (diameter 12 cm). 0 The soil was sprayed with 240 ml of spray solution SL.2 according to the invention, using a diffuser, diffusing, over a period of 48 hours, in each case 30 ml of the spray solution SL.2 according to the invention over the surface of the brown earth every 6 hours. Thereafter, the soil was stored for a further 72 h at 20*C without covering the vessels.
14 For the analysis, the soil was subsequently transferred into a 2-liter vessel and made into a slurry with 1 liter of water at 20 0 C. The mixture was stirred for 20 minutes and the soils were separated from the filtrate using a suction filter. Slurrying and filtration were repeated twice. The water of the collected filtrates were stripped off in a rotary evaporator. The residue was analyzed for the glyphosate content (HPLC). Thus the dosage of glyphosate, based on the acid, amounted to 1340 mg. The amount of eluted glyphosate and the amount of mineralized glyphosate fixed in the soil were calculated 10 accordingly. An analogous procedure was followed for studying the comparative spray solution V-SL1 and the comparative spray solutions SL.3 to SL.5. The results are compiled in Table 1. 15 Table 1: Studies of soil samples V-SL SL2 SL.3 SL4 SL5 Mineralized 1236 410 250 246 700 glyphosate [mg] Mineralized 92 2 glyphosate [ % ] ---- -_-_---

Eluted 104 930 1090 1094 640 glyphosate [mg] 11.2 Long-term mineralization experiments as a function of the sample depths, protocol following the example SL.7 0 In a further experiment, agricultural soil (loose-sediment brown earth) in roof-covered plots in each case I m 2 in size were treated with spray solutions i over a period of 60 days. The depth of the loose-sediment brown earth strata was 90 cm. A plot was treated with in each case a total of 10 liters of SL.7/m 2 over a period of 8 weeks and 5 artificially irrigated with 50 liters of water/m 2 (water hardness < 10 ppm). To this end, the plot was sprayed every 3 days with 0.5 liters of SL.7 followed by irrigation for 6 hours with 2.5 1 water (water hardness < 10 ppm). After the treatment, which lasted for 8 weeks, irrigation was continued for a further 8 weeks without applying other substances (3 liters/m 2 every 3 days). Thereafter, cores down to a depth of 80 cm were sampled using an auger (diameter 10 cm). 4 cores were removed to obtain representative means for the subsequent studies. The cores were divided into disks with a thickness of 10 cm. The amount of the glyphosate fraction which 15 could be eluted with water was determined for these disks, using in each case a procedure as described in 11.1. Table 2: Studies of soil samples in long-term experiments 5 V-SL.6 S7 SL8 SL.9 SL10 [mg] eluted 82 360 393 387 93 glyphosate depth 0-10 cm [mg] eluted 22 290 301 279 26 glyphosate depth 10-20 cm [mg] eluted 9 47 49 39 7 glyphosate depth 20-30 cm [mg] eluted 15 15 12 glyphosate depth 40-50 cm [mg] eluted - 4 3 glyphosate depth 60-70 cm ~[mg] eluted glyphosate depth 70-80 cm The experimental findings demonstrate that the availability of glyphosate by the addition of aminocarboxylates (A) is at a high level despite a certain water hardness (spray solution) and despite the presence of soil minerals. Even SL. 10, which comprises only 26% of the glyphosate 0 fraction, compared with V-SL6, outperformed V-SL.6, in respect of the elutable glyphosate fraction.
