  Pesticide granules are a type of formulation that is advantageous in the agrochemical industry. Pesticide granules are generally produced by extrusion. However, extrusion requires a predetermined viscosity range of the premix to be extruded. If the premix is too fluid, the extrusion yield is significantly reduced. However, many pesticides are only available as liquid compositions. The pesticide is already formulated as a commercial composition for use by the end user or is made in a liquid such as a polymorph. When a liquid composition is used in the premix, the liquid composition can be mixed only in small amounts to maintain the minimum viscosity of the premix. This also reduces the concentration of the pesticide in the produced granules.

  According to one embodiment, the individual components of the composition of the invention, which are part of the kit or part of a two-component or three-component mixture, can be mixed in the spray tank by the user himself. If appropriate, further auxiliaries can be added.

The present invention also relates to a pesticide granule obtained by the method for producing the above pesticide granule. The invention further relates to a pesticide granule comprising a solid support selected from inorganic and organic inert materials, a mixture of sulfosuccinate surfactant and polycarboxylic acid, and a pesticide.

  The present invention also relates to a method for controlling attack by unwanted insects or ticks, harmful fungi and / or undesirable vegetation, and / or a method for regulating plant growth, comprising a pesticide granule or a killing agent. The pesticide granule obtained by the method for producing the pesticide granule is protected from the respective pest, its environment, or the respective pest, the soil, and / or the crop, and / or its The method relates to the environment. The invention further relates to the use of a mixture comprising a sulfosuccinate surfactant and a polycarboxylic acid for preparing a pesticide granule.

  Advantages: The present invention provides a method for producing a pesticide granule that can incorporate higher amounts of a pesticide composition comprising a liquid. The production yield of granules prepared from premixes with high liquid content is increased. High payload granules can be produced that contain pesticides that are available only in diluted form in the liquid.

  The following examples illustrate the present invention without limiting the scope of the invention.

Bentazone: 50% by weight aqueous solution of bentazone sodium sulfosuccinate Surfactant: branched C ₈ -alkyl diester polycarboxylate of sodium sulfosuccinate: copolymer of maleic acid and C ₈ alkyl-α-olefin, mass average Molecular weight 8000g / mol

Example 1
Granules GR-1 to GR-6 were produced. The ingredients listed in Table 1 were mixed in a blender with the exception of bentazone (an aqueous composition containing 50% by weight of bentazone sodium salt). Then bentazone was added and the mixture was kneaded. The obtained kneaded material was extruded with a screen hole of 0.8 mm (KAR-75, Tsutsuki Scientific Instruments Co., Ltd.). After extrusion, the extrudate was manually cut into granules having a length of 1.0 to 2.0 mm and dried at 80 ° C. for 20 minutes with a dryer (FD-LAB-1, Powrex Corporation). Next, sieving was performed with sieves having a mesh size of 1.2 mm and 0.55 mm to remove large lumps and fine particles. The preparation scale was 300 grams. Finally, the amount of the prepared sample was measured and the preparation yield was calculated. Table 2 shows the composition of the pesticide granules.
