Abstract

The hybrid knotweed Reynoutria × bohemica Chrtek & Chrtková exhibits greater genetic variation than its parents. We developed methodology for and tested for glyphosate resistance in two Bohemian knotweed populations using rhizome fragments. There was no difference in LD₅₀ (p = 0.3030; F = 1.067) between the populations and no evidence of resistance.
