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.

Thousands of pests and diseases affect our major livestock species, with impacts on livestock production varying in space and time.

To improve our collective capacity to model and measure the economic costs of pests, weeds and diseases of the major food crops of the world, CSIRO and HarvestChoice-UMN are delivering a series of ecological modeling workshops.

Risk: we all know what that means, right? But why is it such a critical part of our HarvestChoice portfolio, what does it mean when you look through the lens of farming in Sub-Saharan Africa?

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.

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.

Not only crop growth and yield, crop models can be also used to estimate potential damages from pest/disease through a predefined set of damage pathways, or coupling points.

Farming entails a great deal of choices and uncertainties. From season to season, weather varies, price fluctuates, soil degrades, pest damages, and climate changes. Farmers everywhere must cope with these uncertainties. Throughout the history of agriculture, many options have been developed to help manage these risks, increase yields, increase efficiency, and, more recently, promote the sustainability of the overall system.

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.
