Lupin anthracnose

Colletotrichum gloeosporioides

Threat: Lupin anthracnose is a serious disease of all species of lupins, but is more likely to severely damage albus lupins.

About the disease: Anthracnose causes bending and twisting of stems, with dark brown lesions in the crook of the bend. The lesions cause the stems and lateral branches to weaken and collapse.

Spread: Anthracnose is spread by the movement and planting of infected seed. It is more likely to spread in high-rainfall areas with warmer temperatures.
