Soil-Borne Pathogens: Challenges for Diagnosis and Control Strategies

Soil-borne infections are among agriculture's most damaging agents, generating considerable output losses and jeopardising world food supply. These diseases, which include fungus, bacteria, nematodes, and oomycetes, can, live in the soil for decades, sometimes undiscovered, infecting a wide range of host plants. Their cryptic character, capacity to persist as resistant propagules, and complicated interactions with soil microbes make identification and treatment challenging. Advances in molecular biology, genomics, and remote sensing technologies have enhanced pathogen identification, but practical obstacles remain for field-scale applications. Control measures span from cultural practices, chemical treatments, and resistant types to more recent approaches including biological control, soil microbiome engineering, and integrated disease management (IDM). However, environmental issues like climate change impede these attempts. This article discusses the biology of soil-borne diseases, the difficulty of correct diagnosis, and the range of management options, with a focus on the need for integrated, environmentally friendly, and farmer-friendly solutions.
