603302 Disclosed is a dry spreadable or broadcast granule comprising: i) a solid carrier； ii) at least one active chemical agent selected from gamma-cyhalothrin and lambda-cyhalothrin； and iii) an emulsifier system capable of forming a microemulsion of the active chemical agent (ii) upon dilution in water； and wherein the emulsifier system comprises: A) at least one non-ionic surfactant having an HLB >；9 selected from a mono C2-6alkyl ether of a poly C2-4alkylene oxide block copolymer having at least a first polyalkylene oxide block region and a second polyalkylene oxide block region in which the polyalkylene oxide in said first region is different than the polyalkylene oxide in said second region (such as a butyl ether derivative of an ethylene oxide (EO)/propylene oxide (PO) block copolymer ((Toximul® 8320))； and B) at least one hydrophobic anionic surfactant selected from a styrylphenol polyethoxyester phosphate (Soprophor® 3D33)； and wherein the emulsifier system is coated onto, absorbed onto or impregnated into the carrier.
