Root rot is a serious threat to agriculture worldwide, continuously reducing yields and jeopardizing crop survival. Depending on the causal agent, host susceptibility, and the environmental conditions, entire fields can be lost to this disease. In this review work, we present the following root rot causal pathogens: bacteria, virus, oomycetes, and fungi. Bacterial and viral root rots are less common and not many studies have reported these causal agents. Oomycetes and fungi have been found to be the most commonly widespread root rot pathogens. Reported oomycetes are Aphanomyces spp., Pythium spp., and Phytophthora spp. Several fungi were reported to cause root rot, including, Rhizoctonia spp., Fusarium spp. and Phoma spp., Aphanomyceseuteiches and Thielaviopsisbasicola. These diseases are highly influenced by the environment, with a broad range of hosts, hidden underground symptoms and overwinter structures of many root rot pathogens, disease control and management are very complex and hard to achieve. Chemical treatment is generally only available as preventive seed treatment. Chemical treatment is generally only available as preventive seed treatments. Chemicals are also used as a way to kill the green bridge between crops. Overall, despite the complexity of this trait, resistance to root rot through enhanced varieties is the biggest promise to control such devastating diseases.
