Ciba-Geigy: beyond Weed Tables

摘要

Like Alan Hale and Antony Galton, I am one of the grateful, if apparently rare, owners of what appears to be a complete set of the Ciba-Geigy Weed Tables. In my case these were obtained sometime during the 1970s, either at one of the regular sales ofremaindered and damaged books organised by a Cambridge bookseller that were the cheap source of many now valued items, or possibly direct from Ciba-Geigy (see below). Distance in time means that I am uncertain which. The motivation for acquisition in mycase was not only the artistic and diagnostic merit of the Tables, but also their potential use in teaching a course on Weed Biology in a Department of Applied Biology.
