When the red mite, applied with 14C-fenothiocarb by
the contact method, metabolizes fenothiocarb,
resulting in several metabolites via the primary
oxidation of the N-methyl moiety. The
photodegradation of fenothiocarb on silica gel plate
exposed to sunlight gives rise to several degradation products. A primary photochemical reaction seems to
be the oxidation of the sulfur atom to form its
sulfoxide. Under greenhouse conditions, when
fenothiocarb is applied to the citrus trees, the major
metabolites identified in the leaves, rinds, and edible
fruit are 6-O-malonyl-b-D-glucosode of N-
hydroxymethyl fenothiocarb, N-formylfenothiocarb, and
glucoside conjugate of phenol (not shown in the map),
respectively. In soils, fenothiocarb is more rapidly
degraded under upland conditions than under flooded
conditions. Main degradation pathways include
oxidation of the sulfur atom which results in the
formation of methyl-4-phenoxybutylsulfoxide, its
sulfone, and 4-phenoxybutylsulfonic acid.
