Abstract

Barley leaf spots caused by Ramularia, oxidative stress & leaf wax damage, cause leaves to die back early resulting in loss in yield and quality, often leading to screening penalties in malting barley. This project will compare the losses in winter barley with spring barley and look at the way different varieties react to biotic and abiotic leaf spots. The reaction different varieties have on green leaf area retention following fungicide treatment will be measured. QoI (strobilurin) resistance will be studied in the Ramularia population using a PCR tool developed with SEERAD funding. The information from this research will be used alongside results from complementary SEERAD funded research project to develop a risk prediction based on variety and weather conditions to warn HGCA members of the potential for spotting to be a problem and recommend appropriate fungicide action before leaf spots occur. The study will also help understand why varieties (both current and future) are susceptible, resistant or tolerant to leaf spots. Part of the research will investigate the role the mlo mildew resistant gene, found in many UK spring barley varieties, has on susceptibility to other diseases and leaf spots commonly called hypersensitive reaction.
