Metabolism of Planavin Herbicide in a Lactating Cow

Planavin [4-(methylsulfonyl)-2,6-dinitro-n,n-dipropylaniline] herbicide was fed to a catheterized lactating dairy cow at 5ppm in the feed ration for four days. Planavin or possible sulfur-containing metabolites were not detected in milk, urine, or feces by electron affinity and sulfur-flame photomet...

More Information
Summary:Planavin [4-(methylsulfonyl)-2,6-dinitro-n,n-dipropylaniline] herbicide was fed to a catheterized lactating dairy cow at 5ppm in the feed ration for four days. Planavin or possible sulfur-containing metabolites were not detected in milk, urine, or feces by electron affinity and sulfur-flame photometric gas chromatographic analysis. The sulfur detector showed that the herbicide rapidly (15min) decomposed in fresh rumen fluid with production of three sulfur-containing metabolites speculated to be 4-(methylsulfonyl)-2,2-diamino-N,N-dipropylaniline, 4-(methylsulfoxyl)-2,6-diamino-N,N-dipropylaniline and 4-(thiomethyl)-2,6-diamino-N,N-dipropylaniline.
