DCD biodegradation rate is a function of temperature. The half-life of DCD in soils at 25 C is around 6e20 days depending of DCD rates and experiment conditions (e.g. laboratory or field conditions). On the other hand, high rates of DCD (20 mg kg1 or higher) might cause phytotoxic effects including leaf tip and margin chlorosis and necrosis,and reduction in the biomass yield
