Lupinosis is one of the major diseases of grazing livestock in Western Australia. It occurs when animals graze lupin stubble containing toxins produced by the fungus Phomopsis leptostromiformis. The Department of Agriculture has recently released new cultivars of Lupinus angustifolius which are more resistant to colonization by Phomopsis, and therefore develop less toxicity, than those previously available (Cowling et al. 1988). The new cultivars - Gungurru and Yorrel - are called Phomopsis-resistant, however their resistance is only moderate. The old cultivars are referred to as Phomopsis-susceptible.
