Plants were exposed to labeled ATA, The plant metabolites were then 
isolated and fed to rats. Plant metabolite-1l gave rise to two new spots and 
the absence of ATA, Thus, although metabolite-] is further metabolized, it 
was not converted to ATA. Examination of radioautograms prepared from rat 
urine after feeding plant metabolite-2 did not show any new metabolites. The 
presence of ATA in the sample of metabolite-2 prevented drawing of conclusions 
as to whether or not this compound gave rise to ATA (432). 
When exposed to UV (2200 A) amitrole broke down via free radicals and 
gave rise to CO, , urea, and cyanamide (1171). 
Conversion of Amitrole was first order and could be represented by
