The Ultimate Guide to Wheat Diseases

Fungal diseases can devastate wheat yields but they can be prevented through a combination of cultural measures and the use of fungicides.

That’s why, with support from Syngenta, Farmers Weekly has created the Ultimate Guide to Wheat Diseases.

Wheat disease guides

Read the articles in our ultimate guide to managing septoria, yellow rust and brown rust in wheat.

How to manage septoria in wheat

Septoria tritici is the most damaging foliar disease of UK wheat, causing yield losses which can range from around 30% to as much as 50% in high pressure seasons.

We look at the symptoms, risk factors and how to manage what is considered by most agronomists to be by far the biggest threat to UK cereal crops.

Advice on getting ready for the yellow rust onslaught

There has been a surge in yellow rust levels in the last couple of years, believed to be the result of the arrival of new, more aggressive races in the field.

Against this background, it is essential to monitor crops and report any unexpected findings as the season develops, stress the experts.

Control strategies to tackle brown rust in wheat

The emergence of new races of brown rust has seen a renewed focus on how to control a disease which can both slash wheat yields and affect grain quality.

The disease can explode from mid-June onwards and this makes fungicide choices at the ear spray timing of crucial importance.

How to properly set up a crop sprayer

Crop spraying is one of the most important and highly skilled jobs undertaken on any arable farm.

See our best practice guide on optimum sprayer set up to help to maximise the efficacy of applied products, reduce spray drift and keep machinery in good condition.

Disease Force

The Disease Force experts will be visiting three arable farms during the key wheat spraying season, to assess risk and suggest strategies on how best to manage the three major diseases – septoria, yellow rust and brown rust.

Each of the farms in Herefordshire, Kent and Essex are in areas renowned for a heightened risk from the three diseases.

Disease Force farms target top three wheat diseases

Meet the three farmers and experts as they make their first assessment of the disease risk at the start of the season.

Disease Force team explores wheat fungicide strategies

Sprayers were working hard on our three Disease Force farms on our second visit, with T1 treatments being applied to winter wheat in dry and sunny conditions.

Disease Force teams commit on T2 wheat fungicide plans

A change in the weather just ahead of the all-important flag leaf spray prompted our three Disease Force farms to opt for some fungicide firepower.


Watch the Ultimate Guide video on how to set up a crop sprayer and the Disease Force videos. See the first visits with our experts assessing the disease risk in Kent, Essex and Herefordshire and the second visits looking at wheat fungicide strategies.
