Abstract
Gardiner and Kilby have described1,2 the synthesis of the systemic insecticide bis (bis-dimethylaminophosphonous) anhydride (octamethylpyrophosphoramide) in radioactive form (with phosphorus-32) and its application to the study of its uptake by living plants2. We also have experimented along these lines, but have extended our investigations to the study of the chemical fate of the substance, using for this purpose activities of about 400 µC./gm. to obtain the necessary sensitivity in analysis. Preparative details will be published elsewhere.
