Wheat and barley disease management guide

Find out how to manage the most important diseases of wheat and barley


This guide provides an overview of the most important diseases of wheat and barley. It outlines the key options for integrated pest management (IPM), with a focus on the main risk factors and key management steps. Disease management programmes that balance non-chemical and chemical options, in the context of fungicide resistance, are also summarised.

This web page contains all resources referred to within this guide. It also provides links to additional information for the main target diseases.

Integrated pest management (IPM)

Use a pyramid of control measures to manage disease. An appropriate variety (to resist the main diseases present) and a well-designed rotation (to minimise disease pressure) are at the heart of IPM

The effect of foliar diseases

Despite increases in varietal resistance, in most situations, fungicides are required to keep the crop healthy during the growth stages that are most important for yield

The UKCPVS looks to detect new races of cereal pathogens

The AHDB Wheat growth guide allows crop progress, structure and final performance to be measured and compared against a series of UK benchmarks.

The aim of this guide is to enable barley growers to identify where production may be falling short of potential.
