Summary: The influence of the nonionic surfactant, Agral 90, on the activity of imazamethabenz in wild oats ( Avena fatua L.) was investigated in glasshouse and laboratory trials. Agral 90 significantly increased the efficacy of imazamethabenz against wild oats at a range of growth stages; a significant decrease in activity of both imazamethabenz alone or with Agral 90 was observed following application to plants possessing tillers. At 0.1 kg ha −1 , the growth of tillers was significantly reduced by imazamethabenz plus Agral 90. The retention of imazamethabenz on wild oat foliage was significantly increased by Agral 90 incorporation; Agral 90 also facilitated retention of imazamethabenz on the tillers. The absorption and translocation of imazamethabenz were significantly enhanced by Agral 90; greater amounts of the labelled material were found in all regions of the plant except the tillers which existed at the time of application.
