Abstract
This chapter reviews reactions for Dithio and Thiolcarbamates. Cartap hydrochloride, an insecticide, is explained. Nereistoxin, 4-N/, N/-dimethylamino-1, 2-dithiolane, is produced from cartap hydrochloride as a main product through photoreaction under UV irradiation in aqueous and methanolic solutions, and on glass and silica gel surfaces. EPTC is a selective herbicide with control of weeds in a wide variety of crops including corn, cotton, and beans. Fenothiocarb is an acaricide controlling citrus red mite. When the red mite, applied with 14 C-fenothiocarb by the contact method metabolizes fenothiocarb, resulting in several metabolites via the primary oxidation of the N/-methyl moiety. 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-p-D-glucosode of N-hydroxymethyl fenothiocarb, N/-formylfenothiocarb, and glucoside conjugate of phenol, respectively. In soils, fenothiocarb is more rapidly degraded under upland conditions than under flooded conditions. Fenothiocarb Sulfoxide, a metabolite of fenothiocarb is the major metabolite in soils and disappears rapidly in soils. Fenothlocarb sulfoxide disappears much faster than fenothlocarb and the fenothlocarb sulfoxide-treated soils form more bound residues. Molinate, a herbicide, is also discussed, and controls barnyard grass. Orbencarb is a pre-emergent herbicide, and controls weeds in upland fields applied by itself, or along with linuron.
