Triazine injury on the lower leaves of soybeans. Leaves will show interveinal chlorosis and a yellowing of leaf margins and tips followed by browning. Lower leaves are affected most. There may also be reduced root growth. Triazine injury usually results from barry-over in the soil of residues from applications of herbicides containing atrazine in previous years.
