This paper compares the systemic properties and long lasting efficacy of imidacloprid and carpropamid in rice after nursery box application. The physicochemical properties and metabolic stability in both soil and plant influenced the distribution manner of the compounds in rice plants. Metabolic profile indicated that the parent compounds were one of the major components in rice, even at the harvest time, showing the long lasting efficacy of the pesticides. The rather low total radioactive residues found in the rice grains for both compounds,
