The effect of the addition of Silwet L-77 at either 0.1 or 0.2% (v/v) to radiolabelled glyphosate was investigated on 1-, 4- or 6-month-old C. selloana foliage under controlled environment conditions. The addition of Silwet L-77 significantly enhanced uptake only in foliage aged 6 months. The translocation of 14C translocated out of treated leaf portions was significantly reduced in the youngest, unchanged in 4-month-old and increased in the 6-month-old foliage by the addition of surfactant.
