Plantskydd deer repellent – on Rabbit and Possums

Manaaki Whenua Landcare Research

We have now completed preliminary pen trials of Plantskydd® against both possums and wild rabbits. I enclose copies of the data which show the % of individual trees remaining over time, using Treepel as a positive treatment.

I have also enclosed a copy of a paper which explains the method we use for pen assessments of repellents, and attached is a summary of the analysis of Plantskydd® v.Treepel showing a comparison of the mean area under the browse curves. This shows that Plantskydd® was significantly more effective than Treepel against rabbits, and equally effective as Treepel against possums.

If you would like us to continue with a more robust phase of assessment, involving field trials, we would be happy to discuss the options by which this research could be done.

Yours sincerely,
