Net Blotch

See here for net blotch trials on OFT. Net blotch is a plant disease that mostly affects barley. There are two types of net blotch. Net type is caused by by the fungus Pyrenophora teres f. teres and spot type is caused by Pyrenophora teres f. maculata. Symptoms are most commonly found on leaves, but can occasionally be found on leaf sheaths. Net type and spot type net blotch are different in appearance.The net type appears as pin point brown lesions on the leaves which elongate and produce fine, dark brown streaks along and across the leaf blades to form a net appearance.The spot type also similar but the lesions are surrounded by yellow edges. As infection progresses they can elongate and join together. Severe infection reduces green leaf area and kills leaves prematurely and causes reduced seed weight and grain quality.
