Research was conducted to evaluate p-chlorophenyl methyl sulfide, sulfoxide, and sulfone in relation to plant toxicity, chemical uptake by plants from soil, translocation of foliar applied chemicals, and degradation in soil. These three chemicals are closely related and differ only in their oxidation state. Radioactive chemicals were used in the main experiments with C14 being uniformly incorporated in the ring structure. Measurements of degradation, uptake, and translocation were made from total activity measurements of dry combusted soil and plant samples. In addition, the translocation of foliar applied diisopropyl methylphosphonate DIMP was determined in corn and sugarbeets. Author
