title: Carbaryl insecticide: extraction from dust and powder formulations.
abstract: Some 10% and lower guarantee carbaryl dusts cannot be quantitatively extracted by shaking with chloroform as specified in the official first action infrared method for carbaryl formulations, 6.206-6.208. A repeatability extraction study has been made, using a different extraction technique with both chloroform and 10% methanol in chloroform. The results indicate that the new extraction technique and the mixed solvent are suitable for all solid carbaryl formulations. It is recommended that a collaborative study be conducted on the new solvent system and extraction technique.
