The addition of amendments in soils (and the combination with
other techniques such as solarization) tends to decrease
R. solanacearum populations (Davi et al., 1981; Schönfeld et al.,
2003; Gorissen et al., 2004; Islam and Toyota, 2004). Ryckeboer
et al. (2002) demonstrated that R. solanacearum could be
destroyed and drop below detectable limits within one day of
anaerobic digestion at 52 C with source separated household
wastes. Besides, Termorshuizen et al. (2003) showed that
R. solanacearum could drop below detection levels following
a 6-week mesophilic (maximum temperature of 40 C) anaerobic
digestion of vegetable, fruit and gardenwaste. Recently, Noble et al.
