Diseases of wheat

Yellow Rust

Yellow rust is a major disease in wheat. Typical symptoms comprise small yellow pustules on the leaves. They commonly form in lines along the leaf. Look out for small pockets of affected plants in the spring. In severe cases, the leaves will appear bleached.  Read more here.

Ergot

Ergots are fungal resting bodies which contain toxic alkaloids, they are very poisonous to both humans and livestock. Ergots are purplish black in colour, and a similar size to grain, but smaller pieces of ergot may also be present. Read more here.

Septoria tritici

Septoria tritici is currently the major disease in wheat. Although more resistant varieties, including Robigus have recently been added to the HGCA Recommended List, many varieties remain susceptible, including Consort. Issues concerning fungicide resistance have made it more of a challenge to manage in susceptible varieties.  Read more here.

Common eyespot

Common eyespot is a fungal disease which attacks the stems of winter cereals. Winter wheat is affected most, but winter barley can also be affected. Spring crops and winter oats are not so badly affected by this disease.  Read more here.
