The 14C-ADS was applied on the first trifoliate at the second trifoliate stage of the plant. One group of the treated plants was kept under the condition preventing from rainfall. Another group was showered artificially 3 or 7 days after treatment of 14C-ADS and then kept outdoors for 9 or 10 weeks. The residue levels equivalent to alloxydim-sodium in the seeds were 0.022-0.039ppm at 9 weeks and 0.024-0.050 ppm at 10 weeks for all samples. So neither the difference in the condition such as artificial rain nor the difference in the position of 14C-label affected the residue levels in the seeds. About 10% of the radioactivity in seeds harvested 9 weeks after treatment was found in lipid fraction. Most of the radioactivity was detected in the water soluble fraction after precipitating protein fraction, in which about 28% and 5% of the radioactivity were found in case of 7-14C and 1, 5-14C, respectively. Thus the dimedone moiety of ADS was only a little incorporated into proteins.  aPesticida  aResíduo  aSoja  aPesticides effects  aSoybean plant1 aISHIHARA, K.1 aSOEDA, Y.  tJournal Pesticide Sciencegv.4, p.375-378, 1979.
