Yellow Spot Fact Sheet Northern Region
Published: 22 Aug 2011
Yellow leaf spot, also known as yellow spot in Western Australia and Queensland and tan spot in most countries, is caused by a fungus, Pyrenophora tritici-repentis. The fungus can infect all bread wheat, durum and triticale varieties, although most triticales have good resistance.
As plants mature they become more prone to saprophytic infection. This means the stubbles of any variety of bread wheat, durum and triticale can host the fungus, irrespective of resistance rating.
