Allelopathy is a fascinating and perplexing topic that concerns the
chemical interactions of plants. It has profound implications in
agriculture and forestry where species are grown artificially in
mixture, with no evolutionary history of co-existence. The topic of
allelopathy is widely credited as commencing in 1937, when the term
'allelopathy' was coined by Molisch. However, the concept of allelopathy
has been recorded since Greek and Roman times, became extremely
controversial in the first half of the 19th century, and remains so
today.
This book concerns a virtually unknown treatise by Justus Ludewig von
Uslar, published in 1844, which emerges as the first book entirely
devoted to the concept of allelopathy. The book provides the historical
background to allelopathic knowledge, from antiquity to c. 1840. It also
provides for the first time a biography of Justus Ludewig von Uslar, who
is best known as the first Consul-General for Hannover in Mexico, and
Director of the Mexican Company, a British venture mining company. In
many ways von Uslar epitomises the tradition of the gentleman scientist
of the 19th century. The book then offers a full translation into
English of von Uslar's rare treatise, which foreshadows many ideas
current in allelopathic research.
