Abstract
Audus and Quastel1 have recently shown that sodium thiosulphate is toxic to seeds of higher plants, and it has been reported2 that sodium ethyl xanthate is being used commercially as a weed-killer. The accompanying table shows the results of tests for toxicity to wheat seeds of a number of sulphydryl compounds, and may therefore be of interest.
