This created a film of solid amorphous pyraclostrobin. Preferred polymeric surfactants of the group c. In a very preferred embodiment of the present invention, the surfactant additionally comprises at least one non-ionic surfactant. Further formulation additives may also be added during or after the addition of the further pesticide compound. Preferably is comminution is performed at a temperature of at least 10 K below the lowest melting point of any pesticide compound present. At Croda we have a number of polymeric surfactants each designed with a specific architecture.

On aging, a suspension concentrate may phase separate creating a transparent layer of continuous phase on top, supported by a milky layer of dispersed phase.

Determination of heat of fusion by DSC measurement implied that the crystalline material was modification IV of pyraclostrobin. Principally, SCs can be easily diluted with water and thus provide an easy-to-hand Ie way of application of the pesticide in the field.

The customary formulation additives might depend on the active ingredient in a known manner and include, for example, anti-freeze agents, viscosity-modifying agents thickeners or rheology modify- ing agentsantifoams also termed defoamers or defoaming agenssbactericides, coloring agents such as dyes or pigments, and binders.

This process is particularly suitable for the preparation of attlox aqueous suspensions of organic pesticide compounds having a limited water solubility and a low melting point and which are capable of forming at least one stable crystalline form. Potential energy curve achieved with and without polymeric surfactants. The process according to claim 3, where in step b an aqueous suspension of pyraclostrobin is added, where pyraclostrobin is essentially present in the form of its crystalline modification IV.

Croda makes their documentation available in the regions indicated below: The suspension concentrates are dilution stable, even after prolonged storage, i. In yet a further particular embodiment of the invention, the first pesticide compound is pyraclostrobin and the further pesticide compound is chlorothalonil.

As mentioned above, the temperature, where the molten pesticide compound is emulsified in atlkx is chosen that the emulsified organic pesticide compound remains in the form molten droplets.

Then, in a second step a2the emulsion is cooled to a temperature, which is significantly below the lowest melting point of the crystalline form of the pesticide compound. Usually, the weight ratio of the pesticide to the surfactant is in the range of from 2: However, surface properties of the particles are critical to the effectiveness of the polymer.

In a preferred embodiment of the surfactants c. Antifoam agents may be added to the suspension concentrates. The process according to claim 17, which further comprises the addition of at least one formulation additive to the aqueous suspension of the organic pesticide compound.

Suitable surfactants c25 are described atlo. This produces an aqueous suspension where pyraclostrobin is present as its crystalline modification IV. Suitable mixing devices aglox standard vessels containing one or more stirrers.

Therefore, the present invention relates to a process for preparing an aqueous suspen- sion of an organic pesticide compound, which has a limited solubility in water, i.

SCs and FS’s are generally prepared by suspending one or more organic pesticide compounds in water containing suitable surfactants and optionally further formulation additives and comminution of the suspended pesticide particles to the desired particle size.

The EU special committee on pesticides has adopted plans to make the EU pesticide approval procedure more transparent and accountable. Ammonium salt of the semisulfate of an ethoxilated tristyrylphenol So- prophor 4D Microscopy of the emulsion direct after formation and after 24 h revealed that the pyraclostrobin contained in the emulsion was completely amorphous and remained amorphous for at least 24 h. Preferably, an alkaline metal dioctyl sulfosuccinate is employed, wherein the octyl moiety may be linear or branched and wherein the alkaline metal being selected from 4193 and potassium.

A skilled person is familiar with these methods which are described e. Preferably, the polymeric surfac- tants c. This is the volume of syneresis liquid clear liquid on top divided by the total sample volume expressed as a percentage. As mentioned above, the further pesticide compound may be 413 from any pesticide compound which is known to be suitable for co-formulation with the first pesticide compound.

The comminution is performed at a temperature, where the organic pesticide compound remains in the form of molten droplets.

In the SCs, and likewise in the FS formula- tions, the pesticide is present in the form of finely dispersed particles which are suspended in the aqueous liquid phase, which, besides water, usually contains at least one surfactant for stabilizing the pesticide particles and which atloz contain further formulation additives such as rheology modifiers, biocides, dyes, defoamers antifoam agents and anti-freeze agents.

The process according to xtlox of the preceding claims, wherein step a comprises a. The content of such third party sites is not within our control, and we cannot and will not take responsibility for the information or content.

Suitable further pesticides for the purpose of the invention include but are not limited to: In a very aflox embodiment of the present invention, the surfactant additionally comprises at least one atoox surfactant. In another particular preferred embodiment of the inven- tion, the emulsion comprises at least one non-ionic polymeric surfactant, in particular a non-ionic polymeric surfactant of the groups c.

EP EPB1 en In case of pyraclostrobin comminution is performed at temperature in the range from 45 to 90 0 C, in particular from 50 to 80 0 C.
