Researchers launch new 'Rust-Tracker' to monitor deadly wheat fungus in 27 nations
Date:8/31/2012

BEIJING (31 AUGUST 2012)The world's top wheat experts today reported a breakthrough in their ability to track Ug99 and related strains of a deadly and rapidly mutating wheat pathogen called stem rust that threatens wheat fields from East Africa to South Asia. With data submitted by farmers and scientists from fields and laboratories, the creators of the "Rust-Tracker" say they now can monitor an unprecedented 42 million hectares of wheat in 27 developing countries in the path of a windborne disease so virulent it could quickly turn a healthy field of wheat into a black mass of twisted stems and dried-up grains.

"Wheat rusts are global travellers with no respect for political boundaries, and it is highly likely that some of the virulent new strains related to Ug99 will eventually be carried across the Middle East and Central Asia and into the breadbaskets of Pakistan, China and India," said Dave Hodson, developer of Rust-Tracker and a scientist with the International Maize and Wheat Improvement Center (CIMMYT). "Effective control often depends on finding out what is happening in distant regions, and the Rust-Tracker can help scientists assess the status of stem rust and other rust diseases, not only in their own countries, but also in neighboring countries."

At the start of a four-day symposium organized in Beijing by the Borlaug Global Rust Initiative (BGRI), 1-4 September, scientists reported significant progress with developing and introducing 20 new varieties of rust-resistant wheat over the last few years. Seed for the new varieties is being deployed and multiplied in eight frontline nations to produce enough seed for farmers to plant to prevent massive crop loss in case of an epidemic. But the experts in Beijing warned that wheat fields in a significant number of countries remain largely unprotected from the dangerous pathogen.

"The research being presented at this meeting takes us significantly closer to our goal of protecting the g
