Herbisan (Bext-Defoliant, bis(ethylxanthic)disulfide) [Ethyl xanthogen] 
In leaves of cotton and bean plants, Herbisan decomposed to xanthic 
acid and unidentified water soluble materials. This was accelerated by 
light (834).

2-Heptadecy1-aimidazoline 
Studies aimed at elucidating the mechanism by which this material 
exerts its fungistatic activity indicated that 2-heptadecyl-2-imidazoline 
was a competitive inhibitor in the synthesis of the purines guanine and 
xanthine in Sclerotinia fructicola (1491). 
HRS-1422 [3,5-Diisopropylphenyl methylcarbamate] 
After exposure of rats to labeled HRS-1422, Vico, was observed 
(836). When incubated with rat liver microsomes + NADPH), HRS-1422 
gave rise to the N-hydroxy analog and a number of unidentified metabolites 
CUTTS. SEL . * ER2§, 
After exposure to UV (2537 A) , five compounds were observed. 
Treatment of bean plants also gave rise to several unidentified 
compounds (3).
