Terminal residue analysis in grain, straw and soil treated with two different pyroquilon formulations (35 and 50 WP) at three doses was done by HPLC in rice crop. The average recovery of pyroquilon from soil, grain and straw was 79.66, 86.0 and 92.17% respectively. Non detectable residue of fungicide was found in soil, grain and straw samples at harvest at all concentrations and formulations tested.
