Identification and Management: Use the links below to find out more information on the key disease threats to your barley crop. For each disease you will find out the importance of the disease in terms of potential yield penalty, how to identify the disease in its early stages and our advice on the best control strategies.
Rhynchosporium in Barley causes a reduction in grain size, and consequent yield losses of between 2% and 5%. However, severe attacks can result in losses of up to 40%.
Yield losses of 10% to 15% resulting from powdery mildew in barley are common, but losses can be as large as 40%. Grain filling is reduced, leading to shriveled grain and a poor sample.
Ramularia has been established as an economically damaging disease in barley crops in Scotland and nothern England since 1998, and given the right weather conditions has the ability to infect crops throughout the rest of England.
Yellow rust in barley can cause yield losses of 25% in severe, uncontrolled epidemics, and losses of over 50% have been recorded. However, due to it being very easy to control in barley these losses are only recorded in completely untreated crops.
Net blotch in barley can cause yield losses from 10% to 40% with a reduction in thousand grain weight.
