Phomopsis of Lupins

Phomopsis leptostromiformis


Species Affected:



Severe water stress followed by rain near maturity may lead to the early onset of the systemic semi saprophytic stage, which normally occurs after crop maturity. This stage causes the plant to be toxic to stock.

Life Cycle:

Origin and History:


Often worse on heavier soil types.


The stubble of susceptible varieties can be toxic to stock.

Management and Control:

Plant resistant varieties. See Disease Susceptibility of Lupin Varieties

In areas where Lupins are commonly grown control is very difficult. In areas where few Lupins are grown, the disease may be reduced by planting Lupin crops some distance from previously planted areas.

Cut Lupins for hay to prevent toxicity developing.

Grazing strategies can reduce the impact of stock toxicity.
