  Abstract  
  A new long-lasting, polymer-enhanced formulation has been developed for suspension concentrates of synthetic pyrethroids which addresses and remedies the above mentioned problems. This polymer technology, called PolyZone™ technology, prolongs the effectiveness of deltamethrin suspension concentrates on different kind of surfaces. This technology has been integrated into a new deltamethrin-based product called Deltamethrin SC-PE, which extends residuality on concrete and other materials. The World Health Organization has recently recognised this formulation as having a residual lifespan of 6 months, and it has been shown to greatly extend persistence in outdoor applications due to enhanced rain-fastness as shown in outdoor weathering trials.
