Nematode Suppression

Nematodes have been known for decades. Some studies have shown that Crescent Sunn (Crotalaria Juncea) suppresses some nematode species better than chemical nematicides, because unlike a nematicide, which only kills nematodes at the time of application, Crescent Sunn (Crotalaria Juncea) incorporated into the soil continues to suppress nematode populations while the upcoming crop develops.

Nematode suppression mechanisms

The Crescent Sunn (Crotalaria Juncea) nematode suppressors may work in one or more ways;

• Non-host culture of nematodes

• Production of Monocrotaline, a substance toxic to nematodes that inhibit their development

• Stimulation of the activity of natural soil organisms that compete or attack nematodes.
