Abstract: Herbicidal compositions in the form of microcapsules are described which microcapsules have a capsule wall of polyurea and encapsulate a herbicidally active N-chloroacetylcyclohexeneamine or a mixture of a herbicidally active N-chloroacetylcyclohexeneamine and a herbicidally active chloroacetanilide.

Abstract: The invention relates to a process for the preparation of microcapsules having a capsule wall of polyurea and encapsulating a water-immiscible pesticide. The process comprises first dispersing a solution of a polyisocyanate in the sparingly water-soluble pesticide, in the presence of an anionic dispersant and at least one nonionic protective colloid and/or a nonionic surfactant, and subsequently reacting the dispersion with a polyamine, to give a stable aqueous suspension of microcapsules which can be used either direct or after dilution with water as pesticidal composition.

Abstract: The present invention relates to a method of controlling ectoparasites in domestic animals employing used treatment liquid, in which method animals are passed through animal dips/spray races in which there is an aqueous dispersion of a microencapsulated ectoparasiticide, thus achieving a uniform distribution of the active ingredient between the animals.
