Active Ingredients:
100% Diatomaceous Earth (fossil shell flour)
Best For:
Spring parasite load reduction and year-round pasture management as a holistic alternative or complement to traditional wormers.
How It Works:
The microscopic sharp edges of DE scratch and dehydrate parasite larvae in the gut, reducing the chance of further development. It's not a chemical dewormer, but a mechanical one—making it a great rotation tool or preventative during low-risk seasons.
How to Use:
Dosage:
- Ponies: 1 tbsp daily
- Horses under 800 lbs: 2 tbsp daily
- Horses over 800 lbs: 1/4 cup daily
Method:
Mix with daily grain or feed (ensure water is available)
Frequency:
Use daily for at least 30 days, especially during spring and summer. Safe for long-term use when rotated with fecal egg count checks and traditional dewormers.

Diatomaceous Earth (Food Grade)
Natural Equine Parasite Support
Diatomaceous Earth (DE) is a naturally occurring powder made from the fossilized remains of tiny aquatic organisms called diatoms. When fed to horses in safe, food-grade form, it may help support internal parasite management by physically damaging parasite exoskeletons in the digestive tract—without using chemicals.

Holistic Alternative for September
BioWorma®
Biological control for worms
Natural biological control to reduce infective nematode larvae within the manure of grazing animals
-
An in feed non-chemical biological control for the free-living stages of parasitic gastrointestinal nematodes of grazing animals
-
Acts by substantially reducing the numbers of infective worm larvae emerging from manure onto pasture (including chemical/multi-resistant larvae)
-
Biological control with Duddingtonia flagrans is applicable to the larvae of Horses, Cattle, Sheep, Goats and other grazing animals including Deer, Alpacas and Zoo animals
-
A natural fungus that is safe, non-toxic and residue-free
-
It has no negative effects on non-target soil nematodes, dung beetles, earthworms, microarthropods, soil bacteria and fungi.
Active Constituents:
Each gram contains: a minimum of 500,000 chlamydospores of Duddingtonia flagrans IAH 1297.
Properties:
BioWorma® contains the spores of Duddingtonia flagrans, a natural fungus found in soil and on pasture. It is a non-chemical biological control for the free-living stages of parasitic gastrointestinal nematodes of grazing animals, which acts by substantially reducing the numbers of infective worm larvae (including chemical/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 worm larvae (including chemical/multi-resistant larvae), interrupting the crucial re-infestation stage of the parasites’ life cycle, thus reducing the amount of re-infection on the pasture.
The spores are safe, non-toxic and residue-free. There are no negative effects on non-target soil nematodes, earthworms, microarthropods etc.
Biological control with Duddingtonia flagrans is applicable to the larvae of: SEE LABEL FOR FULL LIST

Abridged see DIRECTIONS FOR USE on label and read carefully
-
Treat animals with a suitable chemical wormer.
-
Move treated animals onto low worm pasture (ideally not grazed by the same animal species for a minimum 6 weeks).
-
Commence daily use of BioWorma® to minimise pasture infectivity and maintain the animal’s low worm status.
-
Thoroughly mix BioWorma® with feed or feed supplements. BioWorma® will begin to work immediately within the manure.
-
Recommended for strategic use during periods when weather conditions are conducive to larval development and transmission on pasture at temperatures above 5° Celsius (40° Fahrenheit) throughout the year. Use in conjunction with a recommended worm management strategy program for your area.
