"Though DDT is often seen as the first war-related pesticide, arsenic ranks as an even earlier war hero. Foresters and landscapers used arsenic in the gypsymoth wars before the turn of the century, and then the Army used it somewhat effectively to combat syphilis and several other pests in World War I.

Arsenic?s warrior status also helped prevent a meaningful public dialogue in the United States about its regulation until quite some time after World War I had ended."...
