33 Claims

1. A multiphase agricultural composition in the form of a suspo-emulsion, comprising:

lipophilic droplets containing a mixture of phytosterols, wherein the lipophilic droplets are dispersed in an aqueous phase to form an oil-in-water emulsion,

wherein the mixture of phytosterols comprises β-sitosterol present in at least 30% by weight of the mixture of phytosterols, with the balance of the mixture to 100% comprising campesterol, stigmasterol and brassicasterol; and

wherein the mixture of phytosterols is between 0.2% and 10% of the composition by weight;

at least one first surfactant located at the interface of the lipophilic droplets and the aqueous phase; and

at least one second surfactant suspended in the phase oil-in-water emulsion, wherein the at least one second surfactant is in the form of particles insoluble in the oil-in-water emulsion,

wherein the at least one first surfactant and the at least one second surfactant each independently comprise sucrose stearate, or sucrose palmitate, or a mixture thereof; and

wherein the at least one first surfactant is between 0.2% and 10% of the composition by weight, and the at least one second surfactant is between 0.01% and 5% of the composition by weight.

32. A multiphase agricultural composition in the form of a suspo-emulsion, comprising:

lipophilic droplets containing a mixture of phytosterols, wherein the lipophilic droplets are dispersed in an aqueous phase to form an oil-in-water emulsion,

wherein the mixture of phytosterols comprises ß-sitosterol present in at least 30% by weight of the mixture of phytosterols, with the balance of the mixture to 100% comprising campesterol, stigmasterol and brassicasterol; and

wherein the mixture of phytosterols is between 0.2% and 10% of the composition by weight;

at least one first surfactant located at the interface of the lipophilic droplets and the aqueous phase; and

at least one second surfactant suspended in the oil-in-water emulsion, wherein the at least one second surfactant is in the form of particles insoluble in said emulsion,

wherein the at least one first surfactant and the at least one second surfactant each independently comprise sucrose stearate, or sucrose palmitate, or a mixture thereof;

wherein the at least one first surfactant is between 0.2% and 10% of the composition by weight, and the at least one second surfactant is between 0.01% and 5% of the composition by weight;

at least one preservative; and

at least one fluidifying agent.
