Lupin anthracnose (Colletotrichum lupini) is a fungal disease of lupin plants.
Lupin Anthracnose causes the stems of plants to twist and break and dead patches to appear on the leaves and pods. Lupin anthracnose may lead to complete crop losses in susceptible varieties.
Infected seeds are the main source of spread of lupin anthracnose. Lupin anthracnose can also be spread by infected stubble through rain splash, and movement of spores by contaminated machinery, vehicles, people, animals and fodder between lupin crops and cropping areas.
In October 2016 lupin anthracnose was detected for the first time in commercial crops in the eastern Riverina region of NSW. There has been no further sign of the disease following a successful eradication program, however monitoring continues.
Due to the significant impact the disease has on commercial cropping, Lupin anthracnose poses a potentially devastating risk for Australian farmers.
NSW DPI advises producers follow the five point lupin anthracnose management plan.
If you suspect symptoms of lupin anthracnose it must be reported immediately by calling the Exotic Plant Pest Hotline on 1800 084 881.
