Triazines 
Since chlorosis is the first sign of the effect of triazines on 
plants, interference with CO, assimilation and sugar formation can be 
expected. Studies showing that the Hill reaction is inhibited confirmed 
this. 
Studies have shown that dichloro-s-triazines were capable of re- 
acting with polysaccharides (cellulose) and proteins at or below room 
temperatures (54, 772, 1542).

Infrared spectra indicated that, in the dry state, triazines and 
their metabolites existed in a polymeric state (271).
