EVALUATION OF A BIO-DYNAMIC TECHNIQUE FOR POSSUM PEST CONTROL
Summary: Bio-dynamic control involves burning pest tissue or organs and spreading the ash on areas to be
protected. In New Zealand, bio-dynamic methods have been suggested for repelling possums where they damage
forests or spread disease. We assessed the repellent effects of five bio-dynamic tinctures. First we tested these
materials on possums in pens and noted their effects on foraging behaviour, food consumption, and body weight.
Then we monitored bait consumption from treated and untreated feeder stations in the field. Although an orthodox
herbivore repellent significantly deterred possums, we detected no behavioural or repellent effects of the biodynamic
tinctures in any of our trials. We are unable to recommend these tinctures for possum control.
