Lupin disease anthracnose confirmed in NSW

DPI plant biosecurity director Dr Satendra Kumar said the department had joined forces with Local Land Services and industry to eradicate the fungus from production areas.

“Four albus lupin crops on two adjoining Riverina farms are affected and we are working with LLS, farmers and industry advisors,” Dr Kumar said.

Lupin anthracnose causes lesions on plants, causing bent, twisted stems and pods, which can lead to complete pod loss and malformed, scarred seed.

Lupin anthracnose is spread by infected seed and the fungus can be spread by contaminated machinery, vehicles, people, clothing, animals and fodder.

Suspect symptoms must be reported to DPI by calling the Exotic Plant Pest Hotline, 1800 084 881.

Lupins are a significant winter crop for NSW producers with over 50,000 hectares sown to lupins this season.

NSW has no natural hosts for the fungus and the current infected lupin crops are relatively isolated from one another, making successful eradication a promising prospect.

Initially detected by NSW DPI Plant Pathologist, Dr Kurt Lindbeck, and confirmed by laboratory DNA analysis at the Elizabeth Macarthur Agricultural Institute, the anthracnose damage was particularly severe in the affected lupin crops.

Riverina Local Land Services Agronomist, Lisa Castleman, encouraged all growers to look for signs of the disease and report any suspect cases.

Ms Castleman said lupin anthracnose incursions threaten the sustainability of albus lupin across NSW and all areas where lupins are grown in Australia.

“Enlisting the support of lupin growers is essential to gain rapid control of this outbreak, as we need to protect NSW lupin crops from this new threat,” said Ms Castleman.
