Claims16
In a method of extruding granules containing at least one active ingredient and at least one inactive ingredient and at least one organosilicone surfactant comprising mixing said at least one active ingredient, said at least one inactive ingredient and water to form a composition wherein the improvement comprises combining said at least one organosilicone with said water prior to said mixing and said extruding, wherein said at least one organosilicone surfactant is added in an amount in the range of greater than 0.001 to less than 0.1% by weight of the composition prior to said extrusion.
A method of reducing the temperature of extrusion of an extruded agricultural composition comprising mixing at least one active ingredient, at least one inactive ingredient, water and at least one organosilicone surfactant to form a mixed product, and extruding said mixed product, wherein said at least one organosilicone surfactant is added in an amount in the range of greater than 0.001 to less than 0.01% by weight of the composition prior to said extrusion.
