Description
Dimefluthrin is a pyrethroid pesticide with a broad spectrum, acting by contact, inhalation and repellent by its strong knockdown and killed capability.
Uses
Dimefluthrin is effective against a broad of pest, including mosquitoes, flies, cockroaches and whitefly, etc. Dimefluthrin also use against cloth damaging Lepidoptera (moths) and cloth damaging Coleoptera (beetles) in indoor situations.Dimefluthrin can be used for the control of insects in indoor, non-food use (residences homes, non-food areas of restaurants, schools, warehouses, hotels).
Production Methods
Commercial production of dimefluthrin follows a multistep process. 2,3,5,6 tetrafluoro 4 (methoxymethyl)benzyl alcohol fragment, is prepared first. In parallel, the acid chloride of the chrysanthemic acid analogue is synthesised, a standard step in pyrethroid production. The two components are then coupled via esterification, typically using base catalysis to drive formation of the ester bond. Commercial processes also include isomer control and purification steps to achieve the required trans dominant pyrethroid profile
Mechanism of action
Broad-spectrum acting by contact and inhalation. Fast knockdown. Works by disrupting the nervous system of insects, specifically by altering the function of voltage-gated sodium channels, leading to paralysis and eventual death of the pest
Pesticide Type
Insecticide
