Use

Soil. It is not persistent in soils since its half-life is approximately 6–14 days (Hartley and Kidd, 1987). The short persistence time is affected by soil temperature and moisture content. The half-life of asulam in a heavy clay soil having a moisture content of 34% and maintained at 20°C was 7 days (Smith and Walker, 1977). In soil, sulfanilamide was reported as a product of hydrolysis. In non-sterile soils, this compound further degraded to unidentifiable products (Smith, 1988) which may include substituted anilines (Bartha, 1971).Photolytic. The reported photolytic half-lives for asulam in water at pH 3 and 9 were 2.5 and 9 days, respectively (Humburg et al., 1989)Chemical/Physical. Forms water-soluble salts (Hartley and Kidd, 1987). When heated to 75°C, asulam decomposed to sulfanilic acid, carbamic acid and sulfanilamide. At 90°C, 4-nitro- and 4-nitrosobenzene sulfonic acids were released (Rajagopal et a
