Package-mix agricultural chemical compositions having improved stability

摘要: A concentrate package-mix composition comprising a water-soluble pesticide or plant growth regulator, for example salt of the herbicide glyphosate, and solid water-insoluble flumioxazin, is provided. The regulator dissolved in continuous aqueous phase particles are suspended phase. These particles, individually plurally, intimately surrounded by barrier layer, which comprises either one both water-immiscible organic solvent an emulsifying agent that has hydrophile-lipophile balance (HLB) not greater than about 15. Optionally further viscosity modifying agent, such as colloidal hydrophilic silica, dispersed Compositions invention exhibit enhanced resistance to settling and/or chemical degradation comparison with otherwise similar compositions lacking layer solvent.
