Duddingtonia flagrans reduces the number of gastrointestinal nematodes (GIN) larvae on pasture, which is significantly greater than a chemical wormer can do. (overall reduction averages below):

Fundamental change

The advent of a non-chemical biological control of parasites in grazing animals ushers in a fundamentally different approach to the production of livestock worldwide. We'll keep you informed.

D. flagrans acts in the faeces of the treated animals and is not absorbed into the systemic circulation; accordingly, no systemic toxicity due to the fungus is expected. This was confirmed through a series of toxicology studies in laboratory animals and long-term high-dose safety studies in target animals.”

Using nematophagous fungi for the biological control of parasites

The use of nematophagous fungi for the biological control of nematode parasites of livestock was first investigated in a study where treatment of a pasture plot with spores of the fungi Dactylella bembicoides, Dactylella ellipsospora and Arthrobotrys oligospora reduced...

History & Background

Recent studies

Use of D. flagrans did not have any effect on soil nematodes, earthworms, soil arthropods, soil bacteria and fungi.

The effectiveness of Duddingtonia flagrans has been verified worldwide

The effectiveness of D. flagrans has been verified worldwide. Published studies have been reviewed by Knox (2003), Soder and Holden (2005), Ketzis et al. (2006), Jagla et al. (2013) and Terry (2013), and these are summarised in the linked article.
