  • Publication number: 20020055436
    Abstract: The present invention describes the use of a combination of an agrochemically active compound and a solid carrier material which surrounds the active compound, to suppress antagonistic interactions in a mixture comprising the active compound surrounded by the carrier material, and at least one further agrochemically active compound. Preferred formulations comprising such a combination include herbicides combined with a carrier material together with a safener and/or a growth regulator. Using the formulations according to the present invention, it is possible to suppress antagonistic interactions between different active compounds.
