Livamol with Bioworma Active Ingredient: Duddingtonia Flagrans IAH 1297 Livamol with Bioworma is a nutritional supplement containing the natural biological control, Bioworma, that captures and consumes infective worm larvae (including chemical resistant/anthelmintic multi-resistant larvae) within the manure of grazing animals. Livamol with Bioworma contains the spores of Duddingtonia flagrans, a naturally occurring fungus in soil and pasture. It is a non-chemical biological control for the free-living stages of parasitic gastrointestinal nematodes or roundworms of grazing animals, which acts by substantially reducing the numbers of infective worm larvae (including chemical/anthelmintic multi-resistant larvae) emerging from manure onto pasture.
