Biological control of nematode parasitism.
Duddingtonia flagrans is a non-chemical biological control for the infective stages of parasitic Gastrointestinal nematodes of grazing animals, which acts by substantially reducing the numbers of infective worm larvae (including multi-resistant larvae) emerging from manure onto pasture. When fed to animals, the thick-walled spores remain inert (having no effect within the host animal) and resist digestion, passing through into the manure. There they germinate and form trapping organs that capture, paralyse and consume emerging infective worm larvae (including multi-resistant larvae). The crucial re-infestation stage of the parasites’ life cycle is interrupted, reducing the amount of re-infection from contaminated pasture. This interruption of the life cycle significantly reduces parasitic nematodes on pasture. The spores are safe, non-toxic and residue-free.More information
