This invention relates to a composition comprising a compound of formula (I) and an agrochemical active ingredient selected from ADEPIDYN™ (pydiflumetofen), oxathiapiprolin, sedaxane and azoxystrobin; RO[C(R)(H)C(R)(H)O]X (I), where Ris Calkyl or is Calkenyl; n is from 5 to 50; independently, each [C(R)(H)C(R)(H)O] unit has both Rand Rbeing hydrogen or has one of Rand Rbeing hydrogen and the other being phenyl; provided that at least one [C(R)(H)C(R)(H)O] unit has one of Rand Rbeing hydrogen and the other being phenyl; and X is hydrogen or is selected from Calkyl; and to use of a compound of formula (I) to reduce particle growth (such as nucleation, crystal growth or Ostwald ripening) of an agrochemical active ingredient.

Fungicide formulations with reduced crystal growth

Stabilized liquid agrochemical compositions are provided that comprise flowable, aqueous dispersion concentrates comprising a) a continuous aqueous liquid phase; b) at least one dispersed, solid phase comprising a dispersion of polymer particles having a mean particle size of at least one micron, wherein the outside surfaces of the particles comprise a colloidal solid material and wherein the particles have at least one agrochemically active ingredient distributed therein, optionally a non-porous particulate mineral that acts as a diffusion barrier to slow the release of the active ingredient, and optionally at least one non-cross-linkable mobile chemical such that the extraction of this chemical from the disperse phase renders it porous in a manner that allows the active ingredient to diffuse out. The colloidal solid is used to stabilize the polymerizable resin in an emulsion state during preparation. In one embodiment, the agrochemically active ingredient is a solid and is distributed within the dispersed solid phase or is a liquid and is distributed within the dispersed solid phase. The compositions of the invention can be used directly or with dilution to combat pests or as plant growth regulators.

Stabilized chemical composition

Stabilized liquid cyclopropane compositions are provided which compromise flowable, non-aqueous dispersion concentrates comprising a) a continuous substantially water-immiscible liquid phase and b) a dispersed solid phase comprising cured polymer particles prepared from a polymerizable thermoset resin which particles contain at least one cylcopropene complex, optionally a non-porous particulate mineral, and optionally a non-cross-linkable mobile chemical distributed therein, and wherein the outside surfaces of the particles comprise a colloidal solid material. The compositions of the invention can be used directly or with dilution to combat pests or as plant growth regulators.

Methods for generating high aspect-ratio polymeric particles comprising an active ingredient

Stabilized liquid cyclopropene compositions are provided which comprise flowable, non-aqueous dispersion concentrates comprising a) a continuous substantially water-immiscible liquid phase and b) a dispersed solid phase comprising cured polymer particles prepared from a polymerizable thermoset resin which particles contain at least one cyclopropene complex, optionally a non-porous particulate mineral, and optionally a non-cross-linkable mobile chemical distributed therein, and wherein the outside surfaces of the particles comprise a colloidal solid material. The compositions of the invention can be used directly or with dilution to combat pests or as plant growth regulators.

The present invention relates to methods for generating polymeric particles which comprise one or more active ingredients. The invention also relates to the use of such polymeric particles as a seed treatment. The present technology provides an improved seed treatment suitable for applying plant propagation materials. The seed treatment of the present technology includes the use of high aspect-ratio particles as a seed treatment. The present technology has been found to have advantageous properties associated with the seed treatment including increased adherence of the formulation to the seed and reduced tendency to dust off.
