    Wheat is the key crop for world food security. It covers the largest area of sowing, and alone supplies almost 20 percent of the calories consumed by the world population. Wheat productivity is crucial to meet the increasing demand for food. Rust diseases are among the main constraints affecting wheat production globally, especially when suitable climatic conditions prevail. Rusts affect almost all wheat producing regions, from the Americas to Australia. Wheat production in East and North Africa, in the Near East and West, and in Central and South Asia – which account for over 37 percent of total global wheat production area – is severely affected by wheat rust epidemics. To provide support, FAO continuously reinforces collaboration with its partners to boost countries’ ability to detect and manage these emerging wheat rust races.

    Combatting wheat rust diseases
    Strengthening national capacities and international collaboration
    2017

    Wheat is the most widely grown crop globally and a source of food and livelihoods for over 1 billion people in many developing countries. Rust diseases are historically the most damaging diseases of wheat. Their frequency, extent and impact has increased significantly in the last two decades causing global concerns. Their high capacity of developing new races makes most wheat varieties vulnerable to them. FAO is continuously re-enforcing its collaboration with partners to enhance countries’ capa cities in prevention and preparedness to rust diseases.

    Sustainable wheat rust resistance – Learning from history 2011

    The wheat rusts have a long history of causing considerable loss in productivity and quality of wheat crops. Much work has been undertaken to address this problem and many successes have been achieved. Sustainable rust resistance has been achieved in a number of situations and has provided valuable guidance for future initiatives where this level of protection has not been achieved. The achievements include understanding the impact of the sexual stage in the rust life cycle in facilitating resis tance breakdown and providing inoculum in close proximity to the developing wheat crop, resulting in more frequent and intense epiphytotics. Management options to minimize breakdown events have also been identified. The most significant discovery is that the rusts appear to lack the ability to overcome some sources of resistance, at least in the short term. These are termed durable resistances and their effective deployment in varieties where wheat rusts can be damaging to productivity would app ear to be a very effective strategy to achieve sustainable global rust resistance.
