ISCF WAVE 1 AGRI TECH Development of a diagnostic tool to assess risk levels of pea foot rot pathogens in soils

豌豆根腐病引起根腐病和茎腐病，导致豌豆产量大幅下降，品质下降，每年减产1250万GB。这些病害是由几种不能用杀菌剂控制的土传病原体引起的，损失的严重程度取决于土壤中的病原体水平、土壤结构和天气条件。目前，轮作是缓解这一问题的唯一方法，即几年不种植豌豆。然而，在种植豌豆之前测量土壤中的病原体水平，有可能识别出疾病风险较低的田地。该项目将开发分子工具来量化土壤中的足腐病病原体，并将水平与潜在的产量损失联系起来。这将为豌豆种植者提供一种风险评估工具，帮助他们选择土壤健康的田地种植优质豌豆。英国豌豆生产的效率将提高，土地、水、能源和化肥的使用将减少。

Foot rot diseases in pea crops cause root and stem rots which result in substantial yield losses and reduction in the quality of the peas, decreasing their value by £12.5M per annum. The diseases are caused by several soilborne pathogens which cannot be controlled with fungicides, and severity of losses is determined by pathogen levels in soils, soil structure and weather conditions. Currently crop rotations whereby peas are not grown for several years are the only means of mitigating the problem. However, measuring pathogen levels in soil before planting peas holds the potential to identify fields where disease risk is low. This project will develop molecular tools to quantify foot rot pathogens in soils and link levels to potential yield loss. This will provide a risk assessment tool for pea growers helping them to choose fields with healthy soils for growing high quality peas. Efficiency of pea production in the UK will be increased and the use of land, water, energy and fertilisers will be reduced.
