  • Package-mix agricultural chemical compositions having improved stability
    Patent number: 6569809
    Abstract: A concentrate package-mix composition comprising a water-soluble pesticide or plant growth regulator, for example a salt of the herbicide glyphosate, and a solid water-insoluble pesticide or plant growth regulator, for example the herbicide flumioxazin, is provided. The water-soluble pesticide or plant growth regulator is dissolved in a continuous aqueous phase of the composition and solid particles of the water-insoluble pesticide or plant growth regulator are suspended in the aqueous phase. These solid particles, individually or plurally, are intimately surrounded by a barrier layer, which comprises either one or both of a water-immiscible organic solvent or an emulsifying agent that has a hydrophile-lipophile balance (HLB) not greater than about 15. Optionally the composition further comprises a viscosity modifying agent, such as colloidal hydrophilic silica, dispersed in the aqueous phase.
