• The fate of O, O-dipropyl S-[2-(2-methyl-1-piperidinyl)-2-oxo-ethyl] phosphorodithioate (C 19 490, piperophos) was followed in greenhouse-grown rice after application of 1.6 kg/ha 14C-labeled C 19 490 into the paddy water. At maturity the shoots contained 2.5 ppm and the hulled grains 0.16 ppm 14C-C 19 490 equivalents. Small amounts of unchanged C 19 490 were found in the shoots but none in the grains. The main metabolites found were : 2-(2-methyl-1-piperidinyl)-2-oxo-ethane sulfonic acid, 2-(2-methyl-1-piperidinyl)-2-oxo-ethanoic acid and a fraction of polar unknown substances. O, O-Dipropyl S-[2-(2-methyl-1-piperidinyl)-2-oxo-ethyl] phosphorothioate, 2-(2-methyl-1-piperidinyl)-1-methyl-sulfinyl-2-oxo-ethane, 2-(2-methyl-1-piperidinyl)-1-methyl-sulfonyl-2-oxo-ethane, 2-methyl-piperidine and CO2 were found in smaller amounts.
