Diseases affecting wheat and barley: rusts

Farmers using conventional fungicides for disease control face a number of challenges such as increased regulatory measures and the spread of fungicide resistance. This chapter sums up the wealth of research addressing this challenge, that has targeted understanding rust pathogens better, the deployment of conventional, genetically modified and gene-edited resistance, the use of agronomic factors and the management of fungicide resistance. The key to sustainable disease control appears to be the integrated use of all these methods.
