Spirodiclofen is a new selective, non systemic acaricide belonging to the chemical group of the spirocyclic tetronic acid derivatives. It acts by interfering with mite development, thereby controlling such pests as Panonychus spp., Phyllocoptruta spp., Brevipalpus spp., and Aculus and Tetranychus species. Spirodiclofen is active by contact to mite eggs, all nymphal stages, and adult females (adult males are not effected). Spirodiclofen is structurally 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.
