Offers new applicable in agriculture prepared formulations of the herbicide N-phosphonomethylglycine (glyphosate) containing surface-active tertiary or Quaternary simple amino esters or oxides of simple amino esters.

The background to the invention

Glyphosate is widely known as a highly effective and commercially important herbicide useful to combat the presence of a variety of undesirable plants, including weeds in agriculture. Glyphosate is usually applied in the form of the finished product, dissolved in water, the leaves of annual and perennial grasses and broadleaf plants, etc. is absorbed over a period of time and thus moves throughout the plant.

Usually glyphosate is part of the commercial compositions in the form of soluble salts. Commercially applicable salts are ammonium salts, salts of alkylamines followed, such as Isopropylamine salt, alkali metal salts such as sodium salt, and salt trimethylsilane. However, it is also applicable prepared formulations of glyphosate in its acid form. A typical ready preparative forms of salts of glyphosate are aqueous concentrate is also water-soluble or dispersible in water, dry the finished formulation, especially granules, requiring dissolution or dispersion in water before use.

Under most conditions of the herbicide effectiveness of glyphosate can be substantially improved by incorporating in intended for the use of the composition of one or more surface-active substances (surfactants). It is believed that such surface-active substances are, in part by facilitating the penetration of glyphosate is a relatively hydrophilic compounds through a very hydrophobic cuticle, which usually covers the external above-ground surfaces of plants.

Wyrill and Burnside, Weed Science, volume 25 (1977), pages 275-287, conducted a thorough study of various classes of surface-active substances as agents to enhance herbicide activity of glyphosate used in the form of Isopropylamine salt. They demonstrated that the choice of surface-active substance has an explicit impact on herbicide activity of the prepared formulations of glyphosate, but also the manifestation of the General trend towards greater efficiency of surfactants with high value hydrophiliclipophilic balance (HLB) in comparison with the surfactant of the same class with a low HLB value, they were not observed nikahnama effective surfactants, identified in the study Wyrill and Burnside, were ethoxylated tertiary and Quaternary alkylamines followed.

Commercial ready formulation of glyphosate is often used as surfactants ethoxylated tertiary alkylamines followed, for example ethoxylated tallamy (derived solid fat), with an average of 15 moles of ethylene oxide (EO) per mole tallowamine. Monsanto Company St.Louis, Missouri for many years selling herbicide under the trade name Roundupready formulations of glyphosate containing different concentrations of the indicated surfactant ethoxylated tallowamine.

In European patent 0 290 416 Forbes and others described compositions of salts of glyphosate containing surfactant ethoxylated tertiary alkylamines followed with less than 15 moles of EO. For example, the described composition containing Isopropylamine salt of glyphosate and surfactant ethoxylated cocoamine (a derivative of coconut oil), with an average of 5 moles of EO. Forbes and others claim that can be received certain benefits in the use of such compositions in comparison with compositions in which the level of EO in surfactant widestudio as surfactants ethoxylated Quaternary alkylamines followed. A few examples where surface-active agent is a chloride ethoxylated N-methylcathinone with 2 mol of EO.

A disadvantage of previously known surfactant ethoxylated tertiary alkylamines followed is that when concentrated ready preparative shape provides a good herbicide action, they irritant effect on eyes. In some but not in all cases, irritant effect on the eye can be reduced by turning tertiary alkylamines followed into the corresponding Quaternary (N-methyl)alkylamines followed. In U.S. patent 5 317 003 Kassebaum described glyphosate composition containing as a surfactant surfactant chloride ethoxylated N-methylcathinone with 15 moles of EO and less irritant to the eyes than described above are identical composition, where the surfactants used surfactant ethoxylated tertiary cocoamine with 15 moles of EO.

An alternative solution to the problem of irritation proposed in U.S. patent 5 118 444 Nguyen, where surfactant ethoxylated tertiary alkylamines followed converted into their N-oxides. In primarilyby oxide tallowamine, with 10, 15 or 20 moles of EO.

Another disadvantage of previously known surfactant ethoxylated tertiary alkylamines followed is that when you add water to them they tend to the formation of a thick gel that adds complexity and cost to the production of finished preparative forms containing such surfactants, adds difficulties for the cleaning of vessels and pipelines. In practice, this problem is eliminated by adding to the surfactant antireligious agent, such as polyethylene glycol.

Previously as components of concentrated ready formulations of glyphosate have never been offered surfactant alkoxysilane tertiary or Quaternary simple amino esters or oxides of simple amino esters. In the United Kingdom patent 1 079 588 Texaco Development Corporation examples of surfactants of the ethoxylated alkylamidopropylamine and alkalol(isopropyl)amine, and methods for their production and shows that they are applicable as detergents, dispersing agents, wetting agents, and emulsifiers.

The compositions of this invention can be produced in situ by the user immediately prior to use for drawing on the leaves of plants with a view to their destruction, or suppression, by mixing in an aqueous solution of glyphosate-containing composition and HDMI the military above. Such compositions of the present invention is defined here as the composition for blending in the tank".

Alternatively, compositions of the present invention can be offered to consumers in the form of ready-preparative form or desirable to use dilution (composition, "ready to use"), or as requiring dilution, dispersion or dissolution in water by the consumer ("concentrated" compositions). Such pre-prepared compositions of this invention are stable during storage and can be liquid or dry.

A method of applying the compositions of this invention for the destruction or suppression of weeds or other undesirable plants.

Detailed description of the invention

The compositions of this invention can contain glyphosate in its acid form. However, due to the relatively low solubility of the acid form of glyphosate in water usually prefer a more soluble salt of glyphosate. As in the previously used commercial compositions, particularly preferred salt for water compositions of the present invention is Isopropylamine salt of glyphosate, whereas especially prempeh ready formulation can be used for many other salts, including, but not limited alkylamino, such as dimetilaminovogo and propylamino, alkanolamine, such as monoethanolamine, alkylsulfonate, such as trimethylsulfonium, and alkali metals such as sodium and potassium salts of glyphosate. Regardless of whether you used acid or salt, in General it is preferable to indicate the amount of glyphosate used or contained in the finished preparative form, the term acid equivalent of glyphosate, commonly shortened".E.".

Mix in the mixing tank and ready-to-use compositions of this invention are aqueous solutions containing from 1 to 50 g glyphosate and.E./l, sometimes more. The preferred range for the mix in the tank and ready-to-use compositions ranging from 5 to 20 g and.E. /l

The concentrate compositions of this invention may be aqueous solutions containing from 50 to 500 g and.E. glyphosate/l, and more preferably from 200 to 500 g and.E./l and most preferably from 350 to 500 g and.E./L. an example of a particularly preferred aqueous concentrated composition of the present invention is a composition that contains Isopropylamine salt of glyphosate at 360 g..

An unexpected advantage of the aqueous compositions of this invention as compared with previously known compositions is that the concentration of glyphosate can be increased to very high levels, for example from 450 to 500 g and.E./l, whereas the concentration of the surfactant remains adequate to provide an excellent herbicide characteristics without having to add additional consumer surfactant into the reservoir for spraying. Many of these highly concentrated compositions have extremely good storage stability in a wide range of temperature conditions.

Alternatively, the concentrated compositions of this invention can be dried ready preparative forms, made for example in the form of powders, pills, tablets, or preferably the granules that must dispersing or dissolving in water before use. Typically, such compositions are not insoluble ingredients in large quantities, and ready preparative forms as a consequence completely dissolved in water. Dry water-soluble and water-dispersible compositions of this invention contain from 20% to 80% of predpochtitelnei water-soluble granular composition of the present invention is a composition, which contains the ammonium salt of glyphosate in the amount of 72 weight. %, the same level present in commercial compositions sold by Monsanto Company as herbicide Scout.

In the dry compositions of the present invention glyphosate can serve as a carrier for other ingredients ready preparative form, or can be optionally one or more inert ingredients as a carrier. As an example, the inert carrier may be used ammonium sulfate. Used here, the term "dry" does not mean that the dry compositions do not contain water; a typical dry compositions of this invention contain from 0.5 to 5 weight. percent, preferably less than 1 weight. percent water.

Dry water-soluble or water-dispersible granule ready preparative form of the present invention can be obtained by any known in practice of the process, including, but not limited to, spray drying, agglomeration in the fluidized bed boiler granulation or extrusion. In dry ready formulation of glyphosate may be present as a salt, e.g. the sodium or ammonium salt, or acid. The finished formulation, treatment or alkali metal, ammonium dihydrophosphate, etc. so that after dissolution or dispersion in water by the consumer forms a water soluble salt of glyphosate.

The difference of the compositions of this invention from all previously described glyphosate compositions is the presence of surface-active alkoxysilanes tertiary or alkoxysilanes or alkoxysilane Quaternary simple amino esters or oxide alkoxysilanes simple aminoether having characteristic chemical structure (a)

< / BR>
where R1-C6-C22- alkyl, normal or branched, aryl or alkylaryl; m is an average number from 1 to 10; R2in each of the m groups (R2) - is independently-C1-C4-alkylen; group R3independently-C1-C4-alkylene, and x and y are average numbers, and x+y is in the range from 2 to 60; or (b)

< / BR>
where R1-C6-C22- alkyl, normal or branched, aryl or alkylaryl; m is an average number from 1 to 10; R2in each of the m groups (R2)- is independently-C1-C4-alkylen; group R3independently-C1-C4-alkylene; R4- C1-C4-alkyl; x and y are average numbers, and x+y is in the range from 2 to 60; and-or branched, aryl or alkylaryl; m is an average number from 1 to 10; R2in each of the m groups (R2)- is independently-C1-C4-alkylen; group R3independently C1-C4alkylene, and x and y are average numbers, and x+y is in the range from 2 to 60.

Surface-active bonds alkylamines or oxides alkylamines followed in previously known glyphosate compositions did not contain groups (R2), in other words m=0. We unexpectedly found that glyphosate compositions can be given improved properties by introducing the structure of the surfactant between the group R1and the nitrogen atom from 1 to 10 groups (R2).

Aryl group, if present in R1contain 5-7, preferably 6 carbon atoms and may be partially substituted. The alkyl part of any alcylaryl groups contained in R1have a 1-16 carbon atoms. An example of such alcylaryl group is alkylphenyl, such as Nonylphenol.

However, in the preferred surfactants of this invention R1the normal alkyl or isotrate containing from 8 to 18, for example 10-15 carbon atoms, and is a derivative of the corresponding alcohol. For example, the alkyl is derived synthetic alcohol, such as istelrooy, isotridecanol, linear C12-C14or octadecylamine alcohols.

Deputy R2closest to the nitrogen atom (the nearest group R2), preferred examples is a propylene (-CH2CH2CH2-), isopropylene (-CH3CH(CH3)-) or ethylene (-CH2CH2) group. Preferred examples directly related to the nitrogen groups of R2is linear propylene, with m= 1. If neighboring group R2is isopropylene or ethylene, m is preferably in the range from 1 to 5, most preferably from 2 to 3, and all groups of R2preferably the same.

In preferred examples of the substituents R3independently selected from isopropylene and ethylene. In particularly preferred examples, the group R3are afilename. In the tertiary simple amino esters and oxides of simple amino esters of the present invention preferably x+y was in the range of from 2 to 20. In Quaternary simple amino esters of the present invention preferably x+y was in the range of from 0 to 20. In particular, the preferred interval for x+y in the tertiary and Quaternary simple aminopyrimidine simple amino esters of this invention R4preferably methyl and-- preferably halogen, such as chloride or bromide, phosphate or sulfate ion, or alternatively, may be ion glyphosate or may be made of anionic surfactants included in the final preparative form with simple aminoethanol. For professionals it will be clear that at low pH values, such that we can have a place in the preparations of glyphosate, tertiary simple amino esters likely should be protonated at the nitrogen atom and may be associated with a counterion; in such cases, tertiary amino esters can be represented by the chemical structure shown above for the Quaternary simple aminoether, except that R4is hydrogen. As counterion AND-in the finished formulation of glyphosate with a low pH value, containing tertiary simple aminoether, the most desirable itself glyphosate.

One particularly preferred surface-active substances, applicable in the compositions of this invention is tertiary simple aminoether, in which R1=C12-C14-alkyl, R2=isopropylene, m=2, R3=ethylene and x+y=5.

Other particularly preferred surface-Akti is m R1=C12-C14-alkyl, R2=ethylene, m=3, R3=ethylene and x+y=5.

Two other particularly preferred surface-active substances, applicable in the compositions of this invention are tertiary simple amino esters in which R1=Isodecyl, R2=linear propylene, m=1, R3= ethylene and x+y=2 or 5, respectively.

Another series of particularly preferred surface-active substances, applicable in the compositions of this invention are tertiary simple amino esters in which R1=alkyl, the corresponding coconut oil, R2=linear propylene, m=1, R3=ethylene and x+y=a number in the range from 2 to 10.

Two other particularly preferred surface-active substances, applicable in the compositions of this invention are tertiary simple amino esters in which R1=isotridecyl, R2=linear propylene, m=1, R3= ethylene and x+y=2 or 5, respectively.

Two other particularly preferred surface-active substances, applicable in the compositions of this invention are Quaternary simple amino esters in which R1= Isodecyl or isotridecyl respectively, R2=LINEST used any convenient and effectively enhance herbicide activity amount of surfactant simple amino esters. In the finished formulation for mixing in tanks-mixers and ready to use acceptable very high level of surface-active substances, for example, up to 5% weight/volume or even higher, but for reasons of economy, more normal to use a concentration in the range from 0.125% to 2% weight/volume. Using conventional methods on samples at different plants you can determine the appropriate level of surface-active simple aminoether for inclusion in any particular glyphosate composition.

In concentrated liquid or dry compositions of the present invention surfactant simple aminoether injected preferably in a weight ratio to glyphosate and.E. in the range of from 1:20 to 1:1, most preferably from 1:10 to 1:2, such as 1:6.

Stability during long-term storage is an important commercial quality concentrated ready preparative forms. In the case of aqueous concentrated ready preparative forms of salts of glyphosate, in particular, it is important that the surface-active substances in the finished formulation was not separated from the other ingredients in the form of clearly distinguishable phases. Many water concentrates, made from powerestimator. A distinctive feature of the surface-active amino esters, patentable here is that they show good compatibility with salts of glyphosate, in particular with Isopropylamine salt, which can be seen at a relatively high point of turbidity even in aqueous solutions with high concentrations of glyphosate. In General, for best application it is desirable that the point of turbidity was above the 50oC.

In addition to glyphosate or its salts and surfactant simple aminoether in the finished formulations of this invention may include any other ingredients or additives, if these additional materials do not have a significant antagonistic action on herbicide activity of glyphosate. Examples of such additional materials can serve antiulcerous agents, antifreezes, dehumidifiers, dyes, antimicrobial preservatives or additives to further enhance herbicide activity, such as ammonium sulfate or fatty acids.

You can also enter the second surface-active substance of a class other than common amino esters, such as ethoxylate primary or secondary alcohol, alkilany ether of sucrose or sorbitol or AE ratio simple aminoether to the second surfactant is greater than 1:1, most preferably more than 2:1, for example about 4:1.

Preferably, if the second surfactant is included in highly concentrated ready preparative form of glyphosate present invention, for example, containing 450 to 500 g and.E./l, surfactant simple aminoether is at least 75 weight. % from total amount of surfactant present.

The invention also includes mixtures of glyphosate with other herbicides, if the final preparative form entered surfactant simple aminoether. Examples of such other herbicides are bialaphos, glufosinate, 2,4-D, MCFA, dicamba, simple diphenyl ethers, imidazolinones and sulfonylureas.

Methods of application of ready-made formulations of glyphosate are well known in practice. Water concentrated ready formulations of the present invention is dissolved in an appropriate volume of water and is used, for example, by spraying of weeds or other undesirable plants for their destruction or suppression. Dry concentrated ready formulations of the present invention is dissolved or dispersed in an appropriate volume of water and applied in the same way. ESWL 0.1 to 5 kg/ha, sometimes more. Regular consumption rate glyphosate and.E. for suppression of annual and perennial grasses and broadleaf plants is in the range from 0.3 to 1.5 kg/ha Compositions of this invention can be applied in any convenient volume of water, most typically in the range from 50 to 1000 l/ha
