Abstract
Stable concentrated suspensions readily dispersible in water comprising ammonium sulfate, a surfactant, and an oil. The ammonium sulfate particles are at least about 99 wt. % passable through a Tyler #48 sieve. The surfactant has an HLB rating from about 10 to about 15. The oil is a hydrocarbon or other non-polar oil having a viscosity of at least about 5 centipoises at 40° C. The ammonium sulfate suspensions of the invention are useful as herbicidal adjuvants, herbicidal compositions or for other purposes.
