Abstract: A formulation comprising an active component, a microcapsule and a dye, which protects the active component from degradation by U.V. light. Such formulations can be used in a variety of applications including agrochemical applications, which are also described and claimed.

Abstract: A mammalian pesticidal composition, and in particular a pesticidal composition for the control of insectivores, in which a pesticidal agent comprising one or more low molecular weight halogenated hydrocarbons, and in particular bromoform, is provided in microencapsulated form, for example, in a coacervated gelatinous base. The resultant microcapsule is preferably provided with a moisture resistant coating which is degradable in a mammalian alimentary system. A method of controlling mammalian pests, in particular insectivores such as moles, using the above composition is also described.
