| | Spirodiclofen Usage And Synthesis |
| Description | 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. | | Uses | Spirodiclofen 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). | | Definition | ChEBI: Spirodiclofen is an organochlorine acaricide, a dichlorobenzene, an oxaspiro compound and a gamma-lactone. It derives from a 1,3-dichlorobenzene. | | Synthesis | Spirodiclofen is commercially produced via a multi-step synthesis starting with the condensation of 2,2-dimethyl-1,3-dioxane-4,6-dione (Meldrum’s acid) with 3-(2,4-dichlorophenyl)propanoyl chloride under basic conditions to form an intermediate enol ester, which undergoes thermal cyclisation in the presence of 1,1,1-trichloroethane or similar solvent to yield the spirocyclic core; subsequent esterification with 2,2-dimethylbutyryl chloride and purification give the active compound.
| | Mode of action | Spirodiclofen 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. | | Pesticide Type | Acaricide; Insecticide |
