Definitions

  • the present invention relates to an agrochemical formulation; a method for producing the agrochemical formulation; a method for preparing the agrochemical formulation; a method for controlling phytopathogenic fungi and/or undesired plant growth and/or undesired attack by insects or mites and/or for regulating the growth of plants, a method for stabilizing an oil dispersion; and a method for increasing the viscosity of a continuous oil-phase.
  • Preferred embodiments are described in the dependent claims. Combinations of embodiments with other embodiments are within the scope of the disclosure.
  • agrochemical actives are formulated as liquid concentrates. If the agrochemical active is not soluble in the liquid, it is often necessary to form a stable and homogeneous suspension of the agrochemical active in the continuous liquid phase. If the continuous liquid phase is an aqueous phase, these formulations are known in the art as suspension concentrates (SCs). If the continuous liquid phase is an oil phase, these formulations are known as oil dispersions (CDs). It is desirable that the applicant does not need to homogenize the liquid concentrate before use, since this will require additional time and handling, including exposure to toxic ingredients that may be present in the agrochemical formulation.
  • a major problem for suspensions of particles is that the particles tend to form sediment over time by particle growth and/or settling of the particles. This tendency may be accompanied by caking of the sediment, i.e. the formation of solid sediment that cannot be easily resuspended by the applicant.
  • thickeners are often added to suspension concentrates and oil dispersions. Such thickeners increase the viscosity of the continuous liquid phase, which reduces the influence of gravitational sedimentation and particle-particle interactions in the suspension.
  • OD formulations are advantageous as compared to SC formulation in that no expensive biocides, many of those being under regulatory scrutinization (e.g. BIT, MIT, CIT ) are required to protect the formulation from infestation by microorganisms and fungi. It has been described in WO 2020/126508 that emulsified water droplets in the continuous oil phase of OD formulations are able to stabilize the formulations. However, under certain conditions there is still a need for further stabilizing such OD formulations comprising water droplets.
  • regulatory scrutinization e.g. BIT, MIT, CIT
