  • Patent number: 8883683
    Abstract: A herbicide composition includes a fenoxaprop ester and a weak acid buffer system. The buffer system maintains the herbicidal composition at a pH in the range of 4 to 8. In one non-limiting embodiment, the fenoxaprop ester is fenoxaprop ethyl. The buffer system can include an amine-containing material, such as a tertiary amine. The herbicide composition can include other herbicides, such as weak acid herbicides, for example pyrasulfotole, bromoxynil, and/or bromoxynil esters and can include one or more safeners.

  • Patent number: 6716457
    Abstract: The present invention relates to a process for inhibiting or eliminating the growth of microorganisms in pesticide suspensions. More particularly, the process of the present invention includes the addition of a combination of peracetic acid, hydrogen peroxide, and water to the pesticide suspension. Further, the process of the present invention includes the application of the peracetic acid, hydrogen peroxide, and water combination to the interior surface of the vessel in which the pesticide suspension is contained. Still further, the process of the present invention includes the application of the peracetic acid, hydrogen peroxide, and water combination to a surface in which the pesticide suspension is in contact.

  • Patent number: 6048542
    Abstract: The present invention provides a composition for inhibiting the growth of microorganisms in water-based pesticide suspensions. In accordance with this invention, the composition comprises from about 0.01% to about 60% by weight of a pesticide; from about 0% to about 20% by weight of a surfactant; from about 0% to about 20% by weight of an antifreeze agent; from about 0% to about 5% by weight of a viscosity builder; from about 0.5% to about 2% by weight of acetic acid; and from about 10% to about 99.49% by weight of water. In a preferred embodiment of the invention, the acetic acid has a pH of from about 3 to about 5.
