Metabolism of dyfonate in rats was studied .../with (35)S label/. ...Diethyl phosphate and thiophosphate, methylphenylthioether, and thiolate analog of dyfonate were observed.
When phenyl (35)S fonofos was administered to mice, the (S)p isomer was eliminated, primarily in urine, more rapidly than the (R)p isomer. In addition to unchanged fonofos, other identified (35)Slabeled metabolites included: fonofos oxon, diphenyl disulfide, diphenyl disulfide oxide, methyl phenyl sulfoxide and sulfone, and 3-OH- and 4-OH-phenyl methyl sulfones. When phenyl (35)S-fonofos oxon was used, (35)S-labeled metabolites included methyl phenyl sulfoxide, methyl phenyl sulfone, and 3-OH- and 4-OH-phenyl methyl sulfones.
Dyfonate was incubated with microsomes ...from rat livers. ...The oxon, eop /o-ethyl ethylphosphonic acid/, etp /o-ethyl ethylphosphonothioic acid/ and thiophenol /were identified/ as major microsome metabolites. Formation of etp and the oxon required presence of nadph2.

When (14)C ethoxy labeled dyfonate was administered /to rats/, 95% of label was found in urine; 5% in feces; and ...0.5% in exhaled air. With (35)S label, 63% of dose was recovered in urine; 32% in feces; 2% in tissues; and 0.1% in exhaled air.

/After oral admin in oil to rats/ ...polar products ...excreted in urine and feces.
After a single oral or ip dose of fonofos labeled in the ring position, 98% of the radioactivity was excreted in the urine and feces within 96 hours. Conditioning with unlabeled fonofos did not change the excretion pattern. Excretion of radioactivity from the (14)C-ethoxy moiety was essentially complete in 4 days, with about 91% in the urine, 7.4% in the feces, and 0.35% in the expired air. Radioactivity in the bile was an important source of activity in the feces. Tissue residues were very small and had virtually disappeared by the 16th day.
When plants were grown in nitrogen deficient nutrient solution, concentration of dyfoxon /metabolite/ in greens were reduced due to deficiencies of all elements (potassium, calcium, and magnesium) except nitrogen.

The disclosure provides formulations comprising synthetic oligoglucosamines and methods for improving plant growth and crop yield therewith. These formulations may be applied to propagating materials, including seeds and other regenerable plant parts, including cuttings, bulbs, rhizomes and tubers. They may also be applied to foliage, or soil either prior to or following planting of propagating materials. Such applications may be made alone or in combination with fungicides, insecticides, nematicides and other agricultural agents used to improve plant growth and crop yield.
