  • Patent number: 4061770
    Abstract: An aqueous, flowable composition containing a high concentration of a solid, essentially water-insoluble, pesticidally-active component homogeneously dispersed therein is prepared by wet-milling the active component in an aqueous matrix together with dispersants. The flowable, pesticidal composition obtained exhibits significantly improved pest control by comparison to that possessed by similar compositions containing air-milled, pesticide components of like average particle size.

  • Patent number: 3948636
    Abstract: An easily handled, flowable, pesticide composition contains as essential components in water as the sole liquid medium, from 10 to 60%, by weight, of at least one solid, substantially water-insoluble pesticidally-active ingredient; from 1 to 10%, by weight, of a water-soluble nonionic surfactant; and from 0.02 to 1% by weight of a heteropolysaccharide gum. Optional ingredients of the composition include, for example, antifoam agents, anticaking agents, and freeze-point depressants. This composition is an extremely stable suspension. It is totally dispersible in water, providing agglomerate-free pesticidal spray compositions.
