Damage from
uptake of Karmex (diuron) herbicide is evidenced by chlorosis
between the veins of the older leaves. These areas may drop out
form the leaves.

Damage from
uptake of Surflan (oryzalin) herbicide is seen in the youngest
tissue and growing points. They appear malformed, twisted and pale
green. In severe instances they may not develop at all and you will
see tip dieback.
