The Ultimate Guide to Wheat Diseases

Fungal diseases can severely decimate yields of Britain’s most important crop – wheat. Fortunately, farmers can largely avoid this through a combination of cultural measures like variety selection and the use of fungicide chemistry.

That’s why we’re bringing you the Ultimate Guide to fungal diseases in wheat.

The guide offers valuable information to help farmers fight the three most important fungal diseases – septoria, yellow rust and brown rust.

Our Disease Force team of experts will regularly visit three farms to assess risk in real time and put the Ultimate Guide knowledge into practice as the season progresses.

Watch the videos on the Ultimate Guide’s how to set up a crop sprayer and the our three Disease Force farms in Kent, Essex and Herfordshire.

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.
