Effect of Storage Temperature on The Stability of Chemical and Physical Properties of Profenofos Insecticide Formulation (EC)

摘要

PROFENOFOS insecticide was subjected to different storage conditions at the temperatures 54 °C for 14 days, zero "C for 7 days according to FAO specifications (1998) and, in sunny place and in dark place for 360 days according to Egyptian conditions. Chemical stability of profenofos was stable if stored either at 54 "C or zero °C for 14 and 7 days, respectively conformed with Food and Agriculture Organization (FAO) specifications during periods of storage and more degradated in sunny place than in dark place. Physical properties (pH range, Emulsion stability and re-emulsification) became conformity with FAO specification.
