<em>Photolytic.</em> When methidathion in an aqueous buffer solution (25°C and pH 7.0) was exposed to filtered UV light (l >290 nm) for 24 hours, 17% decomposed to 5-methoxy- 3H-1,3,4-thiadiazol-2-one. At 50°C, 56% was degraded after 24 hours. Degradation occurred via hydrolysis of the thiol bond of the phosphorodithioic ester. Under acidic and alkaline conditions, hydrolytic cleavage occurred at the C-S and P-S bonds, respectively (Burkhard and Guth, 1979). Smith et al. (1978) demonstrated that methidathion degraded to methidathion oxon at a faster rate in six air-dried soils than in moist soils. Half-lives for methidathion in the air-dried soils ranged from 19 to 110 days. In addition, methidathion degraded faster in an air-dried soil exposed to ozone (half-lives 2.5 to 7.0 days).<br /><em>Chemical/Physical.</em> Emits toxic fumes of phosphorus, nitrogen and sulfur oxides when heated to decomposition (Sax and Lewis, 1987). Methidathion oxon was also found in fogwater collected near Parlier, CA (Glotfelty et al., 1990). It was suggested
