The response of plant disease to weather variables such as temperature and precipitation is well known, and has been the basis for disease forecasting models used in decision-making by farmers and policy makers. Thus, plant disease risk can readily shift under climate change. Predicting changes i...

This technical study focuses on the role of micro-organism genetic resources for agriculture and the influence of a changing climate. Agriculture is defined as crop-based food production for yield and quality. It excludes micro-organism genetic resources associated with livestock, fish and non-fo...

Seed systems have an important role in the distribution of high-quality seed and improved varieties. The structure of seed networks also helps to determine the epidemiological risk for seedborne disease. We present a new approach for evaluating the epidemiological role of nodes in seed networks, ...

To satisfy a growing demand for food, global agricultural production must increase by 70% by 2050. However, pests and crop diseases put global food supplies at risk. Worldwide, yield losses caused by pests and diseases are estimated to average 21.5% in wheat, 30.0% in rice, 22.6% in maize, 17.2% ...

Virus‐related degeneration constrains production of quality sweet potato seed, especially under open field conditions. Once in the open, virus‐indexed seed is prone to virus infection leading to decline in performance. Insect‐proof net tunnels have been proven to reduce virus infection under rese...

Resistance genes are a major tool for managing crop diseases. The networks of crop breeders who exchange resistance genes and deploy them in varieties help to determine the global landscape of resistance and epidemics, an important system for maintaining food security. These networks function as ...

Synchytrium endobioticum (causal agent of potato wart) is a devastating soilborne pathogen. Eradication is difficult and infestation can result in 100% yield loss, making this a strictly quarantined pathogen worldwide. Emerging epidemics pose a high risk to production in Georgia where potato is a...
