Absorption and distribution of C¹⁴-labeled tetramine in relation to its possible use in animal damage control

Abstract

Tetramethylenedisulphotetramine (tetramine) is an extremely toxic chemicaI (Hagen 1950).' Shortly after its discovery in Germany (Hecht and Henecka 1949L it was introduced in the United States and found useful as an experimental seed protectant in reforestation by direct seeding (Spencer 1954). The first indication of tetramine's systemic characteristics was that seedlings grown from tetramine-treated seed were toxic to rodents during the first month after germination ( Spencer 1954). This observation led to (1) bioassay studies to determine translocation of the chemical and (2) pen and field tests to evaluate the effectiveness of tetramine as a systemic chemical for protecting seedlings against wild animals (Kverno 1960). In order to more fully evaluate the potential usefulness of tetramine for practical application, additional studies were undertaken of the chemical's translocation patterns in plants and its fate in plants and animals: This paper, one of several reports on these studies, describes the patterns of absorption, translocation, and mobility of tetramine in three plant species.
