The present invention relates to the use of 24-membered cyclodepsipeptides of the formula (1)in which Rand Rare as defined in the description,for controlling animal pests in veterinary medicine, hygiene, agriculture, forests and in the protection of materials, to pesticides comprising these depsipeptides and to novel depsipeptides of the formula (1).

Pest control agents/depsipeptides

Pest control agent/PF 1022-221

The invention relates to novel carbazate intermediates of formula (II), and to a process for their preparation, and their usefulness in the preparation of (1,3,4) oxadiazine derivatives useful as pesticides, in particular as anthelminthicides, insecticides, acaricides, and nematicides.

1,3,4-oxadiazine derivatives and their use as pesticides

The invention relates to novel deoxycyclodepsipeptides which are prepared from cyclodepsipeptides having 24 ring members which are constructed from alternating &agr;-aminocarboxylic acids and &agr;-hydroxycarboxylic acids, by complete or partial chemoselective reduction of the carbonyl groups of the amide function to give methylene groups using suitable reduction processes, and to mixtures and derivatives thereof. The deoxycyclodepsipeptides according to the invention have anthelmintic activity.

Desoxycyclodepsipeptides and their use for combatting endoparasites

The invention relates to a novel process of preparing (1,3,4)-oxadiazine derivatives of formula (I) and to their usefulness as pesticides in particular as anthelminticides, insecticides, acaricides, and nematicides.
