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.
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.
As a quick demonstration to estimate crop yield levels at regional-scale with various management assumptions, this post describes how crop systems models can be used to assess yield gap of rainfed maize due to the limited supply of soil nitrogen. This methodology can help researchers to find what is the most critical factor that limits crop yield productivity in a given environment condition and how to address the constraint.
