The rice had been sprayed in a paddy field in Wakayama city , with 3 kinds of pesticide application protocols : spraying once at the usual concentration of pesticides , repeated spraying ( 3 times ) with the usual concentration of pesticides and spraying once with 3 times the usual concentration of pesticides . The residue levels of pesticide decreased during the rice cleaning process . Silafluofen , which has a higher log Pow value , remained in the hull of the rice . Fenobucarb , which has a lower log Pow value , penetrated inside the rice . The residue concentration of pesticide in polished rice was higher than that in pre-washed rice processed ready for cooking . During the cooking procedure , the reduction of pesticides in polished rice was higher than that in brown rice .
