Use

Biological. From the first-order biotic and abiotic rate constants of chlorothalonil in estuarine water and sediment/water systems, the estimated biodegradation half-lives were 8.1–10 and 1.8–5 days, respectively (Walker et al., 1988). Soil. Metabolites identified in soil were 1,3-dicyano-4-hydroxy-2,5,6-trichlorobenzene, 1,3-dicarbamoyl-2,4,5,6-tetrachlorobenzene and 1-carbamoyl-3-cyano-4-hydroxy-2,5,6- trichlorobenzene (Rouchaud et al., 1988). The half-life was reported as 4.Groundwater. According to the U.S. EPA (1986) chlorothalonil has a high potential to leach to groundwaterPlant. Degrades in plants to 4-hydroxy-2,5,6-trichloroisophthalonitrile (Hartley and Kidd, 1987), 1,3-dicyano-4-hydroxy-2,5,6-trichlorobenzene and 1,3-dicarbamoyl-2,4,5,6- tetrachlorobenzene (Rouchaud et al., 1988). No evidence of degradation products were reported in apple foliage 15 days after application. The half-life of chlorothalonil was 4.1 days (Gilbert, 1976)
