Biological Worm Control

BioWorma®

Drench resistance is a growing crisis in New Zealand, making traditional chemical wormers increasingly ineffective for grazing animals. For lifestyle block owners on smaller acreage, managing pasture contamination can be especially tough. BioWorma® offers an organic and highly effective tool in the toolbox.

What Is It?
A Natural Biological Control 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.
Safe, Non-Toxic & Residue-Free The spores are safe, non-toxic and residue-free. There are no negative effects on non-target soil nematodes, earthworms, microarthropods etc. There is no withholding period for meat or milk.
How It Works

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 reinfestation stage of the parasites' life cycle, thus reducing the amount of re-infection on the pasture.

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.

Dosage & Administration

Abridged — see DIRECTIONS FOR USE on label and read carefully.

1
Treat first

Treat animals with a suitable chemical wormer.

2
Move to low-worm pasture

Move treated animals onto low worm pasture (ideally not grazed by the same animal species for a minimum of 6 weeks).

3
Start BioWorma® daily

Commence daily use of BioWorma® to minimise pasture infectivity and maintain the animal's low worm status.

4
Mix with feed

Thoroughly mix BioWorma® with feed or feed supplements. BioWorma® will begin to work immediately within the manure. Feed 3 grams per 50 kg of bodyweight daily.

5
Use strategically

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.

Pack Sizes
2kg BioWorma® at 50kg bodyweight each
4 x sheep or goats for 5.5 months
7.5kg BioWorma® at 50kg bodyweight each
10 x sheep or goats for 8.2 months

BioWorma® is a fantastic tool in the toolbox, but should be used strategically as part of a wider worm management strategy, for best results. Contact Sez the Vet for a consultation around how to customise a management plan for your specific block.
