Abstract

Anthracnose in lupins, caused by Colletotrichum lupini, was first detected in commercial crops in Western Australia (WA) in 1996. This incursion of an exotic plant pathogen into Australia constituted a major biosecurity threat to the local lupin industry. The disease caught the industry unawares with the majority of cultivars at that time being susceptible and there were major issues with local plant pathologists and lupin agronomists having very little exposure to diagnosis and management of this disease. In 1997, the first major breakthrough was made when resistance to anthracnose was confirmed in several breeding lines and commercial cultivars of narrow–leafed lupins (Lupinus angustifolius), and landraces of Lupinus albus. These findings led to the release of cultivars with elevated levels of resistance to the disease. Important information on relative yield loss, critical seed infection levels, fungicide seed treatment and geographical risk factors have also been discovered through applied research leading to use of seed testing and registered fungicides for the control of early infection.

In addition, a spatio–temporal model was developed to simulate the spread of anthracnose initiated by infected seed and other sources. The modelling has contributed to the formulation of strategies for management of lupin anthracnose. An extension campaign through field days, seminars and regular media exposure promoted the management package developed from the research.
