Abstract
Solvent systems for the formulation of alkyl thiophosphoric triamide urease inhibitors, that provide stable dispersion of alkyl thiophosphoric triamides for even distribution (in low or high concentrations) onto fertilizers containing urea in liquid or solid form.
Claims25
A composition comprising:
- a) at least one alkyl thiophosphoric triamide, wherein the alkyl thiophosphoric triamide is present in an amount between 15% by weight of the composition and 35% by weight of the composition;
- b) a solvent comprising at least one dioxolane compound of formula (Ia):
- wherein R6 and R7 individually comprises an alkyl group, an alkenyl group, or a phenyl group, wherein n is an integer of from 1 to 10, wherein the dioxolane compound is present in an amount from at least 25% by weight of the composition;
- wherein the composition has an absence of amide solvent.
