Spirodiclofen is a new selective, non-systemic acaricide belonging to the chemical group of spirocyclic tetronic acid derivatives. It controls mites by interfering with mite development, thereby helping to manage pests such as Panonychus spp., Phyllocoptruta spp., Brevipalpus spp., and Aculus and Tetranychus species. Spirodiclofen acts on contact with mite eggs, all nymphal stages, and adult females (adult males are not affected). Structurally, spirodiclofen is similar to spiromesifen, which is also a tetronic acid insecticide. Spirodiclofen is registered worldwide for use on a variety of crops, including citrus, pome fruits, stone fruits, grapes, and ornamentals.
Spirodiclofen is a tetronic acid acaricide and fungicide used for controlling red mites. It is also used as a component in cannabis testing kits as part of pesticide mixes. As a spirocyclic tetronic acid derivative, spirodiclofen provides excellent acaricidal activity and is used worldwide to control the majority of important mite species.
