Crop pathogens and pests reduce the yield and quality of agricultural production. [] Key Result Our results document losses associated with 137 pathogens and pests associated with wheat, rice, maize, potato and soybean worldwide.
An expert-based assessment of crop health is reported on, and numerical estimates of yield losses on an individual pathogen and pest basis for five major crops globally and in food security hotspots are provided.
A global surveillance system for crop diseases
A Global Surveillance System (GSS) is proposed that will extend and adapt established biosecurity practices and networking facilities into LICs, enabling countries and regions to quickly respond to emerging disease outbreaks to stabilize food supplies, enhancing global food protection.
Contrasting National Plant Protection Needs, Perceptions and Techno-Scientific Capabilities in the Asia-Pacific Region
Pests and pathogens inflict considerable losses in global agri-food production and regularly trigger the (indiscriminate) use of synthetic pesticides. In the Asia-Pacific, endemic and invasive
The global burden of plant disease tracks crop yields under climate change
For most crops, yields are likely to increase at high latitudes but disease risk will also grow, and the benefits of yield gains will therefore be tempered by the increased burden of crop protection.
Impacts of climate change on tomato, a notorious pest and its natural enemy: small scale agriculture at higher risk
Climate change (CC) clearly impacts food production, but risks on the climatic suitability of agricultural areas for vegetable crops, their pests and associated natural enemies are largely
Salinity Stress Management in Field Crops: An Overview of the Agronomic Approaches
Crop plants have defined roles in the global food supply. Cereals, pulses, beans, and grains are particularly important for their nutrients and easy availability for consumers who cannot purchase
Resistance Breeding Increases Winter Wheat Gross Margins–An Economic Assessment for Germany
Improved wheat varieties have ameliorated our food production. Intensive cropping systems, as in Germany, achieve very high grain yields and thus contribute greatly to global food security. As
Plant health and its effects on food safety and security in a One Health framework: four case studies
Four case studies on plant health issues directly tied to food safety and/or security and how a One Health approach influences the perception and mitigation of these issues are presented to demonstrate the complex interrelationships between plants and public health.
When the Medicine Feeds the Problem; Do Nitrogen Fertilisers and Pesticides Enhance the Nutritional Quality of Crops for Their Pests and Pathogens?
It is demonstrated that routine applications of pesticides and/or N-fertilisers may inadvertently reinforce the problem of P&P damage in agriculture by enhancing the nutritional quality of crops for these organisms.

Despite a clear increase in pesticide use, crop losses have not significantly decreased during the last 40 years, however, pesticide use has enabled farmers to modify production systems and to increase crop productivity without sustaining the higher losses likely to occur from an increased susceptibility to the damaging effect of pests.
Crop pests: Crop-health survey aims to fill data gaps.
The International Society for Plant Pathology's online global survey of experts in crop health is determining the importance of crop pests and diseases in five staple crops and has revealed large geographical gaps in the available expert knowledge on crop losses.
Economic and physical determinants of the global distributions of crop pests and pathogens
If every country had US levels of per capita GDP, then 205 ± 9 additional pests per country would be reported, suggesting that enhanced investment in pest observations will reveal the hidden threat of crop pests and pathogens.

Crop health and its global impacts on the components of food security
The literature on the importance of plant pathogens sometimes emphasizes their possible role in historical food shortages and even in famines. Aside from such major crises, plant pathogens should
Rice Pest Constraints in Tropical Asia: Quantification of Yield Losses Due to Rice Pests in a Range of Production Situations.
One major finding was that some (attainable yield × injury factors) interactions significantly contributed to the description of variation in actual yield, indicating that some injuries had a stronger or weaker yield-reducing effect, depending on the level of attainable yield.
Plant disease: a threat to global food security.
Conventional plant breeding for resistance has an important role to play that can now be facilitated by marker-assisted selection, and there is also a role for transgenic modification with genes that confer resistance.
The role of biodiversity in the dynamics and management of insect pests of tropical irrigated rice—a review
P pest management of much tropical irrigated rice must be based on natural controls rarely supplemented by insecticides, and there is no evidence that a natural control-based approach, as recommended in this review, is incompatible with farmer practicability or with future developments in rice production.
Rapid emergence of pathogens in agro-ecosystems: global threats to agricultural sustainability and food security
It is argued for a re-design of agro-ecosystems that embraces the concept of dynamic diversity to improve their resilience to pathogens.
