fordon (4-Amino-3,5,6-trichloropyridine-2-carboxylic acid) 
Carboxy-labeled-tordon-cl4 was metabolized by cotton plants and 
soil microorganisms and cl4o0, was evolved. About 4% of the applied 
material was bound by the insoluble plant proteins. This was freed 
by acid hydrolysis (Meikle et al., 1965). 
After spring wheat was grown on pre-treated soil, the main plant 
residue was the unchanged compound. In low levels, several metabolites 
were also present: 4-amino -6-hydroxy-3,5-dichloropicolinic acid, 
oxalic acid, lipids hydrolyzable to all three acids, and 4-amino-3,5,6- 
trichloropyridine (Redemann et al., 1965).
