Instant Insights: Rust diseases of cereals

Description

This collection features five peer-reviewed reviews on rust diseases of cereals.

The first chapter provides an overview of the wheat rust pathogen lifecycle and discusses recent integration of basic biological knowledge and genomic-led tools within an epidemiological framework.

The second chapter introduces stripe rust and provides an overview of its decimation of crop yields worldwide. The chapter summarises recent advances in identifying stripe rust resistance genes in wheat as a means of controlling disease spread and limiting its economic damage.

The third chapter addresses the need for more effective and sustainable control of rust pathogens affecting wheat and barley in the face of increasing regulatory measures against the use of conventional fungicides, as well as the spread of fungicide resistance.

The fourth chapter provides an overview of the recent advances in controlling wheat rust, focussing on the role of pathogen and host genetics, host-pathogen interactions, epidemiology and management strategies.

The final chapter considers the main rust pathogens affecting sorghum and details the different conditions in which they proliferate, their symptoms and impact on crop yields.
