Right-sizing Stem Rust Research

Stem rust is a potentially devastating fungal disease that can kill wheat plants and small grain cereals, but more typically reduces foliage, root growth, and grain yields. The pathogen multiplies rapidly, and its spores can be dispersed by wind over thousands of kilometers.

Abstract

We estimate global wheat losses over the past 50 years absent investments in research to limit impacts of stem rust and discuss how this can inform decisions about “right-sizing” research investments.

CSIRO and HarvestChoice: Our Partnership to Take on Global Hunger

CSIRO and HarvestChoice

Australia’s Commonwealth Scientific and Industrial Research Organisation (CSIRO) and HarvestChoice are now working together to apply innovative, “bio-economic” approaches to improve the food security of poor people in sub-Saharan Africa and South Asia. Together, our organizations will merge biological, environmental and economic tools to track global food pests and better target strategic investments to improve global food security. 

How We're Pioneering the Mapping of Pests (Video)

Jason Beddow of HarvestChoice and the University of Minnesota, along with Darren Kriticos of CSIRO, explain how HarvestChoice is revolutionizing the science of tracking -- and predicting -- the paths of devastating crop pests and diseases such as UG99.

Rust Diseases and Global Food Security

Wheat stem rust

Coming up in December, I'll be honored to give the keynote address at the Field Crops Rust Symposium in San Antonio. Crop rust – wheat stem rust, in particular – is a topic we’ve spent a lot of time with in recent years, and we’re making fresh progress (see this recent paper) toward mapping and understanding the threat both in Africa and here in the U.S.
