Translocation of Glyphosate in Strawberry Stolons

Abstract Field growing nonfruiting strawberries ( Fragaria x ananassa Duch. ‘Midway’) were treated with ( methyl - 14 C) glyphosate ( N -(phosphono-methyl)glycine] applied to the leaves of runner plants rapidly developing at the nodes of stolons. Seven days after application, 14 C was distributed throughout the stolon and untreated new runner plants. The greatest accumulation of 14 C was found in the stolon and in the runner plants distal to the application site. When the distal runner plant was treated, most of the 14 C was recovered from the application site. Depending upon the treatment, from 2.9% to 11.5% of the recovered 14 C activity was located in the mother plant.
