Spirodiclofen Usage And Synthesis
DescriptionSpirodiclofen 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.
UsesSpirodiclofen is a tetronic acid acaricide fungicide used in controlling red mites. Spirodiclofen is used in cannabis testing kits as a component of pesticide mixes (P698240).
DefinitionChEBI: Spirodiclofen is an organochlorine acaricide, a dichlorobenzene, an oxaspiro compound and a gamma-lactone. It derives from a 1,3-dichlorobenzene.
Mode of actionSpirodiclofen is a progenitor of tetronic acid derivates (inhibitors of acetyl CoA carboxylase), characterized by an original (unique) mechanism of action which combines long-lasting protection with anthocorid safety for effective integrated pest management.
It interferes/inhibits the lipid biosynthesis of Mites, Mealybugs and Pear-psylla.
