Citrus is susceptible to a number of fungal soil-borne pathogens as Phytophthora spp (Timmer and Menge, 1988), Phoma tracheiphila (Ezra et al., 2007), Rosellinia necatrix, Armillaria mellea and Fusarium spp. (Smith et al., 1989). The relevant importance of “Dry root rot” associated with Fusarium solani is governed by agro-climatic conditions, varietal susceptibility, soil type, water logging, drought conditions, and other abiotic factors which cause stress on the tree (Feder et al., 1956; Labuschagne et al., 1987; Smith et al., 1989). Dry root rot caused by Fusarium species is a serious problem in certain countries (Naqvi, 2004); especially when it has an interaction with root rot disease caused by Phytophthora species (Dandurand and Menge, 1992), and with citrus nematode Tylenchulus semipenetrans (Riff) (Zafar, 1998).
