The present invention relates to a solution for increasing the compatibility of a solution fertilizer with a plant protection agent.

The need to apply both liquid fertilizers and crop protection products at the same time as application technology allows, is particularly increasing. This has the following benefits:

—Saving live and machine labor and working time, - Reduces soil compaction, reduces trail damage and tread damage.

U.S. Patent No. 3,408,174 discloses a composition comprising a mixture of salts of sulfuric fatty acids and salts of alkylbenzenesulfonic acid.

Application of solution fertilizers and pesticides in a single pass without additives is generally not practicable because the latter will lump, settle, mix, or precipitate as an oil when mixed with liquid fertilizer and pesticide. In such cases, uniform application cannot be achieved and often the plant protection product is unable to exert its biological effect.

In the case of pesticides in the form of saline fertilizers, the mixing problems of certain formulations of the pesticide, such as wettable powder formulation (WP), suspension concentrate (SC) or emulsifiable concentrate (EC), must be investigated.

In the case of WP and SC formulations, the following conditions must be met for co-application: good spontaneous wettability, good dispersibility, i.e., ability to suspend with minimal flocculation, and finally good redispersibility, i.e., the flocculated parts can easily be resuspended by mixing.

In the case of EC pesticides, which form an o / v emulsion, the formation of an electric double layer can explain the stability. The dissolved salts have different effects on the electrical bilayer depending on their quality and the valence of their ions. In addition to specific effects, concentration also plays an important role; in general, as the ion concentration increases, the electrical bilayer is compressed more and more, thereby bringing the emulsion droplets closer together, allowing them to converge more readily, thus impairing the stability of the emulsion. This problem can also occur because of the ionic content of the water used to make the sprayer, which can be exacerbated by the hardness of the water. Therefore, the stability of growth agent emulsions is known as the so-called. in standard water, that is, 19.2 nk ° in water. Due to the higher ion concentration of solution fertilizers, a stable emulsion with pesticides is often not formed.

Attempts have already been made to solve the misalignment of non-miscible solution fertilizers and pesticides, as the need for a 2-compatible formulation is increasing due to the widespread use of liquid fertilizers and the pursuit of more economical production.

One known but only a cation group for compatibility with a narrow group of solution fertilizers and pesticides consists of an anionic surfactant or a mixture of anionic nonionic surfactants. For example, U.S. Pat. No. 3,317,305 utilizes a phosphate ester prepared in a suitable manner for this purpose. To this end, phosphorus pentoxide was reacted with dinonylphenyl and ethylene oxide condensate, and the resulting disodium triester mixture was added to the plant protection products and the resulting concentrate was added to the fertilizer solution. U.S. Pat. No. 4,224,049 discloses a (alkylaryl) poly (oxyethyl) glycol phosphate monoester as an active ingredient, and a composition comprising water and a lower alcohol, preferably methanol. The disadvantage is that the active ingredient can only be produced by complex synthesis. In addition, its methanol content is particularly harmful to health and the volatility of methanol also causes difficulties in use, not to mention that the partially costly components significantly reduce the economic benefit of co-application.

It is an object of the present invention to provide a composition which enables the fertilizer of any solution to be applied in one pass with growth agents.

The present invention is based on the discovery that a high-ionic solution fertilizer, such as a 1: 1 molar mixture of urea-ammonium nitrate, a 28-30% N-containing fertilizer (UAN) solution, or 8-11% by weight Nt and 24- NP and NPK solutions containing 37% by weight of P20s and 0 to 10% by weight of K ₂ can be mixed with conventionally formulated, non-miscible pesticides in the presence of an alkyl polyoxyoxyethylene glycol ether in an oxygen-containing organic solvent .

The invention is further based on the discovery that the effect of the composition of the preceding components can be further enhanced by the addition of a mixed polyethylene glycol alkyl ester.

Finally, the present invention is based on the discovery that an otherwise useful plant nutrient such as urea and an inorganic salt containing N, P or K plant nutrients, such as potassium or ammonium chloride, are beneficial to the composition for handling and use. in the presence of nitrate, sulfate, phosphate. Of course, due to the dose used, these chemicals are not specifically plant nutrients, but they play an important role in reducing the freezing point and evaporation of the compatible salt promoting composition, thus improving its handling.

Accordingly, the present invention relates to a solution for promoting the compatibility of a solution fertilizer and a herbicide which is an alkyl polyoxyoxyethylene glycol ether of the general formula (I) wherein R 'is from 6 to 24, preferably from 10 to 18 carbon atoms and n is 4 to 20, preferably 10 to 15, in an amount of 0.05 to 12.0 wt.%, Preferably 0.15 to 1.5 wt., Based on alkyl pollen (oxylethylene) glycol ether of general formula (I), (II). ), wherein R ² is C 1-4 alkyl, preferably C 1 alkyl, R ³ is 9-21, preferably 11-17, and m is 4-20, preferably 12-18. in an amount of 0.10 to 60% by weight, preferably 0.3 to 1.0% by weight, based on the alkyl pollen (oxyethylene) glycol ether of the general formula (I), and an oxygen-containing organic solvent; poll (oxy water-soluble inorganic salt or salts containing up to 10% by weight, preferably 0.05-2% by weight, of urea and / or N and / or P and / or K and / or alkyl of formula I containing up to 70% by weight, preferably from 0.2 to 10% by weight, of polyoxyethyleneglycol glycol ether, and optionally with water and, where appropriate, water-based additives or additives commonly used in formulating pesticides.

One preferred embodiment of the composition according to the invention is 32% by weight of heptadecyl pentadeca (oxylethylene) glycol ether, 10% by weight of a mixed ester of polyethylene glycol of average molecular weight 900 with acetic acid and lauric acid, 20% by weight of n-butyl alcohol, 8.4% by weight. containing urea and 29.6% water, i.e. the weight ratio of the ingredients in the order listed is 1: 0.31: 0.63: 0.26: 0.93.

Preferred compounds of general formula (I) are the following: octadecyl tetra (oxyethylene) glycol ether, hexadecyl pentadeca (oxyethylene) glycol ether, heptadecyl pentadeca (oxyethylene) glycol ether, nonyl. pentadeca (oxyethylene) glycol ether, octyl monodeca (oxyethylene) glycol ether and dodecylhexa (oxyethylene) glycol ether.

Preferred organic solvents containing oxygen are ethanol, n-butanol, isobutanol, acetone, methyl ethyl ketone, ethyl acetate, diethyl glycol and methyl glycol ether.

Preferred compounds of formula (II) are polyethylene glycol acetate palmitate, polyethylene glycol acetate laurate, polyethylene glycol butylate laurate and polyethylene glycol acetate stearate.

The water-soluble inorganic salt is preferably potassium nitrate, ammonium nitrate, ammonium phosphate and potassium sulfate.

The composition according to the invention provides for the mixing of solution fertilizers and pesticides used in agricultural practice. As is known in agriculture, a solution containing ammonium nitrate and urea in a 1: 1 molar ratio (UAN solution) is the most widespread. The commercially available fertilizer for this solution contains 28-30% N and is marketed by manufacturers under different names (Nitrosol 28 containing 28% N and 30% N by Hydronit 30). In addition, the composition can be successfully used for the co-application of commercially or locally prepared urea solutions and ammonium phosphate and polyphosphate solutions (NP solution) as well as various but mainly KCI-containing solutions (NPK solution) and plant protection agents.

Dosage of the composition of the invention before use is determined by examining the compatibility of the composition. To this maximum dose of solution fertilizer (UAN solution, NP solution, urea solution, NPK solution), the maximum permissible dose of the pesticide to be applied in one pass is added in the presence of the composition of the invention and the stability of the emulsion or suspension is tested. This is done by mixing 0.1 to 2.0% by weight of the solution of the compatibility composition to the fertilizer of the solution, and then adding the pesticide to determine the lowest concentration of the composition of the invention which is still stable. provides a mixture. In practice it is advisable to use this amount or 5-10% higher.

The main advantages of the composition according to the invention are: - it allows the application of a solution of fertilizer and herbicide:

- it also allows the application of pesticide combinations that can only be mixed separately with the dissolved fertilizer;

- in many cases enhances the efficacy of the plant protection product and thus allows dose reduction.

Combined application provides the known benefits of: - saving living and mechanical labor and working time, - reducing soil compaction, - reducing crop and tramline damage to the crop.
