Description

The present invention relates to a composition comprising an agrochemical active substance and a copolymer which comprises an N-vinylcarboxamide and a diallyldialkylammonium salt incorporated into the polymer. The invention furthermore relates to a process for the preparation of this composition; to the use of this composition for dispersing agrochemical active substances; to a method of controlling phytopathogenic fungi and/or undesired plant growth and/or undesired insect or mite attack and/or for regulating the growth of plants, wherein the composition is allowed to act on the respective pests, their environment or the plants to be protected from the respective pest, on the soil and/or on undesired plants and/or on the crop plants and/or their environment; and furthermore to seed comprising the composition. The present invention comprises combinations of preferred features with other preferred features.

A wide range of polymers are known as adjuvants for agricultural formulations:

EP 0 808 568 discloses a multilayer intercalated system incorporating pesticides and a water-soluble polymer. A suitable one is polyquaternium-6, a poly(diallyldimethylammonium chloride).

US 2004/0170657 discloses an aqueous emulsion, the aqueous phase comprising a salt of a crop protection agent, and an amphiphilic block polymer. The hydrophilic block of the block polymer may be constructed of diallyldialkylammonium salt.

Disadvantages of the prior art are, inter alia, that no high storage stability of the formulation is achieved; that the particle size growth of dispersed agrochemical active substances is not slowed down or suppressed; that the agglomeration of dispersed agrochemical active substances is not slowed down or suppressed; that the settling of dispersed agrochemical active substances is not slowed down or suppressed; and that abovementioned advantages manifest themselves in particular in the presence of high salt concentrations. It was therefore an object to overcome these disadvantages.

The object was achieved by a composition comprising an agrochemical active substance and a copolymer which comprises an N-vinylcarboxamide and a diallyldialkylammonium salt incorporated into the polymer.

The copolymer is preferably a random copolymer. The term “random” usually means that the incorporation of at least two different monomers into the resulting polymer is randomly distributed. Usually, the random copolymer is a free-radical polymer, in other words a polymer prepared from monomers by free-radical polymerization.

The copolymer is usually synthesized in the usual manner by means of free-radical polymerization. However, it is also possible to employ other processes for the polymerization, for example controlled free-radical processes. The polymerization is carried out in the presence of the monomers and of one or more initiators and can be carried out with or without solvent, in emulsion or in suspension. The polymerization can be carried out as a batch reaction, as a semicontinuous operation or as a continuous operation. The reaction times are generally in the range of between 1 and 12 hours.

Gels can also be described as viscoelastic fluids; their fluid properties may lie between those of an ideal liquid and those of an ideal solid. The gels may be dimensionally stable, which can mean that they have a viscosity of at least 1000 mPa·s. The figures given for the viscosity in the context of the present invention refer to values as obtained using a Brookfield viscometer (1.5 rpm, Sp 63) at a temperature of 25 degrees centigrade. The composition according to the invention may have a viscosity of below 1000 mPas, preferably below 800, and in particular below 500 mPas.

To treat plant propagation materials, in particular seed, it is customary to use water-soluble concentrates (LS), suspensions (FS), dusts (DS), water-dispersible and water-soluble powders (WS, SS), emulsions (ES), emulsifiable concentrates (EC) and gels (GF). These compositions can be applied to the propagation materials, in particular seed, in undiluted or, preferably, diluted form. Here, the composition in question can be diluted 2- to 10-fold so that from 0.01 to 60% by weight, preferably from 0.1 to 40% by weight, of active substance are present in the compositions to be used for seed dressing. The application can be carried out before or during the sowing. The treatment of plant propagation material, in particular treatment of seed, is know to a person skilled in the art and is performed by dusting, coating, pelleting, dipping or immersing the plant propagation material, the treatment preferably being carried out by pelleting, coating and dusting or by the in-furrow treatment, so that for example premature germination of the seed is prevented. It is preferred to use suspensions for the seed treatment. Usually, such compositions comprise from 1 to 800 g/l active substance, from 1 to 200 g/l surfactants, from 0 to 200 g/l antifreeze agents, from 0 to 400 g/l binders, from 0 to 200 g/l colorants and solvents, preferably water.

The active substance concentrations in the ready-to-use preparations can be varied within substantial ranges. In general, they are between 0.0001 and 10%, preferably between 0.01 and 1%. The active substances can also be used successfully in the ultra-low-volume method (ULV), it being possible to apply compositions with more than 95% by weight of active substance, or indeed the active substance without additives. For use in plant protection, the application rates are between 0.001 and 2.0 kg of active substance per ha, preferably between 0.005 and 2 kg per ha, especially preferably between 0.05 and 0.9 kg per ha, in particular between 0.1 and 0.75 kg per ha, depending on the nature of the desired effect. When treating plant propagation materials, for example seed, amounts of active substance of from 0.1 to 1000 g/100 kg of propagation material or seed, preferably from 1 to 1000 g/100 kg, especially preferably from 1 to 100 g/100 kg, in particular from 5 to 100 g/100 kg, will generally be used. When used in the protection of materials or storage materials, the application rate of active substance depends on the nature of the field of application and on the desired effect. Conventional application rates in the protection of materials are, for example, from 0.001 g to 2 kg, preferably from 0.005 to 1 kg, of active substance per cubic meter of treated material.

Substances which may be admixed to the active substances or to the compositions comprising them are various types of oils, or wetters, adjuvants, herbicides, bactericides, other fungicides and/or pesticides, optionally also only just before use (tankmix). These agents can be admixed to the compositions according to the invention in the weight ratio 1:100 to 100:1, preferably 1:10 to 10:1. Adjuvants in this sense which are suitable are, in particular: organically modified polysiloxanes, for example Break Thru S 240®; alcohol alkoxylates, for example Atplus® 245, Atplus® MBA 1303, Plurafac® LF 300 and Lutensol® ON 30; EO-PO block polymers, for example Pluronic® RPE 2035 and Genapol® B; alcohol ethoxylates, for example Lutensol® XP 80; and sodium dioctylsulfosuccinate, for example Leophen® RA.

A further subject is a method of preparing the composition according to the invention by bringing the terpolymer and the agrochemical active substance into contact, for example by mixing. The abovementioned auxiliaries can optionally also be brought into contact with the composition. Further preparation methods for various types of compositions are as described above.

A further object is the use of the terpolymer for dispersing agrochemical active substances. The terpolymer is preferably used for suspending. Preferred agrochemical active substances are as described above.

The present invention furthermore relates to a method of controlling phytopathogenic fungi and/or undesirable vegetation and/or undesired insect or mite attack and/or for regulating the growth of plants, wherein the composition according to the invention is allowed to act on the respective pests, their environment or the crop plants to be protected from the respective pest, on the soil and/or on undesired plants and/or on the crop plants and/or on their environment. The term crop plants also includes those plants which have been modified by breeding, mutagenesis or recombinant methods, including the biotechnological agricultural products which are on the market or in the process of being developed. Genetically modified plants are plants whose genetic material has been modified in a manner which does not occur under natural conditions by hybridizing, mutations or natural recombination (i.e. recombination of the genetic material). Here, one or more genes will, as a rule, be integrated into the genetic material of the plant in order to improve the plant's properties. Such genetic modifications also comprise posttranslational modifications of proteins, oligo- or polypeptides, for example by means of glycosylation or binding of polymers such as, for example, prenylated, acetylated or farnesylated residues or PEG residues.

Advantages of the present invention are, inter alia, that it makes a high storage stability of the formulation possible; that the particle size growth of dispersed agrochemical active substances is slowed down or suppressed; that the agglomeration of dispersed agrochemical particles is slowed down or suppressed; that the settling of dispersed agrochemical active substances is slowed down or suppressed; that the abovementioned advantages are also attained in the presence of high salt concentrations.

The examples which follow illustrate the invention without imposing any limitation.

EXAMPLES

  • Surfactant A: Anionic surfactant, sodium salt of an alkylnaphthalenesulfonic acid, water-soluble.
  • Surfactant B: Nonionic surfactant, alkylamine ethoxylate, water-soluble, surface tension (1 g/l water, room temperature) approximately 40 mN/m.

Example 1—Copolymer A

Initial charge: 216 g polyethylene glycol, average molar mass 35 000 g/mol

    • 216 g polyethylene glycol, average molar mass 1500 g/mol
    • 164 g propanol
    • 0.96 g triallylamine

Feed 1: 384 g N-vinylformamide

    • 147.7 g diallyldimethylammonium chloride (DADMAC; 65% by weight form)
    • 164 g propanol

Feed 2: 2.9 g tert-butyl peroctoate

    • 164 g propanol

Feed 3: 420 g propanol

Feed 4: 100 g propanol

    • 16 g sodium methoxide (30% by weight)

The homogenized initial charge was heated to 90° C. with nitrogen being passed through the system, and feed 1 was metered in over 4 hours, and 112 g of feed 2 over 5 hours. After an hour of subsequent polymerization, 55 g of feed 2 were added and polymerization was continued for a further 1.5 hours. Then, using feed 3, dilution and cooling took place. Finally, the quantity of feed 3 was removed by distillation, feed 4 was added, the batch was heated under reflux for an hour, and the distillation was repeated. This gave copolymer A, containing N-vinylformamide and DADMAC in an 80/20 weight ratio. The molar mass Mw was 151 000 g/mol, with a PDI of 7.5. The solids content was 35% by weight (120° C., 2 hours), and the pH (in 10% form) was 4.5.

Example 2—Formulation

14 g of pyraclostrobin, 2 g of copolymer A from example 1, 2 g of surfactant A, 3.3 g of surfactant B, 13.1 g of glyphosate isopropylammonium salt (60% by weight in water), and 21.6 g of water were weighed into a vessel. 25 ml of glass beads (0.75-1.0 mm) were added, and an aqueous pyraclostrobin suspension was prepared by shaking on a laboratory shaker (4 h, 400 rpm). Thereafter, the glass beads were filtered off.

Example 3—Formulation (Comparative Experiment)

An aqueous suspension of pyraclostrobin was prepared as in example 2, the terpolymer of example 1 being replaced by

    • A) Atlox® 4915, or
    • B) Copolymer B (acrylic acid/AMPS 70/30).

Atlox® 4913 is a composition comprising 33% by weight of terpolymer (reaction product of methacrylic acid, methyl methacrylate and methoxypolyethylene glycol methacrylate), 33% by weight of propylene glycol, 1% by weight of xylene and 33% by weight of water), HLB value 11-12, commercially available from Uniquema.

The random copolymer B comprised the following monomers incorporated into the polymer: 70% by weight of acrylic acid and 30% by weight of the sodium salt of acrylamidopropanesulfonic acid (AMPS).

Example 4—Stability Test of the Suspension

The aqueous suspensions of examples 2, 3A and 3B were stored without agitation for 24 hours at room temperature and thereafter assessed visually with reference to a scale of from 1 (phase separation, no longer dispersible by shaking, clumpy) to 10 (no phase separation, highly viscous, readily dispersible).
