In the United States deer browse causes an estimated $750 million in damage to forest regeneration programs. Besides immediate browse damage, residual problems include: growth suppression, future yield reductions, growth deformities, regeneration delays and plant mortality where plants are repeatedly browsed or pulled out of the ground. This is a cost the forest industry can no longer afford.
The combined application cost of Plantskydd product, and labor, was $0.015/seedling (1.5 ¢) when treating seedlings at the nursery, approximately 1/10th that of treating seedlings folllowing planting (15 ¢/seedling). Download Report – 6.5 MB .PDF Document

Evaluation of eight repellents in deterring eastern cottontail (RABBITS) herbivory in Connecticut —Scott C. Williams & Michael R. Short— Dept. of Forestry and Horticulture, Connecticut Agricultural Experiment Station, New Haven, CT, USA
Plantskydd Deer Repellent has been an important silviculture tool within our Company’s reforestation program for over 12 years.
Plantskydd® was first developed in Sweden in 1991 in response to commercial forest plantations being decimated by deer, moose and rabbits. The forest industry needed an animal repellent that could last through severe weather and meet Sweden’s strict environmental laws.
Plantskydd’s effectiveness as a long lasting animal browse repellent was substantiated in Field Trials 1991-1994 and the results published in the Scandinavian Journal of Forest Research – J. Berquist & G. Olander, Swedish University of Agricultural Sciences – ASA Forest Research Station, 1996.
In Canada and the United States, Plantskydd’s effectiveness as an animal browse deterrent has been confirmed since 1994 in Operational Level Field Trials undertaken by large forest industry cooperators on millions of conifer and deciduous trees of various species.
It is now considered the most cost-effective and environmentally safe animal browse deterrent available and is used by leading forest companies, nurseries, private woodlot owners, landscapers, home gardeners, as well as State/Provincial and Federal Conservation agencies.
Available in either soluble powder, pre-mix or granular formulation, Plantskydd repels: deer, elk, moose, rabbits and opossum by means of odor – which is not offensive to either applicators or planters either during or after plant treatment.
Plantskydd’s effectiveness as an animal browse deterrent has been confirmed in operational conditions since 1993 by large forestry companies on millions of conifer and deciduous trees of various species. Plantskydd’s effectiveness is attributed to its tenacity in sticking to plants, even under severe snow/rainfall – lasts up to 6 months over winter on dormant plants!
