How Harmful Are Nematodes on Lupins

A nematode is any kind of parasitic worm belonging to the nematoda group. This species of worm can live in large numbers in soil, water, animals and plants, including the lupin family of flowers.

Lupin Susceptibilty

• Generally, lupins are poor hosts to nematodes, as they have a resistant gene that is secreted in an enzyme found in Lupin roots. Planting lupins usually reduces the amount of nematodes in the soil and should aid in reducing nematode reproduction.

Blue Lupins

• Blue lupins are more prone to attacks by nematodes than other lupin varieties. The reasons for this are not clear, but it is likely this variety of lupins has a lower concentration of alkaloid chemicals that make its resistance to pests weaker. This lupin also has the highest biomass, which could contribute to susceptibility.

Lupin Benefits

• Lupin are good at aerating soil, as they have deep taproots. Lupins help to create a better planting environment for other crops. Lupins can grow in most types of soil and are a useful plant to stop the proliferation of weeds.
