Plantskydd Deer Repellent is considered the most cost-effective and environmentally safe animal repellent available. Plantskydd is accepted and used by leading forest companies, nurseries, private woodlot owners, landscapers, and home gardeners, as well as State/Provincial and National Conservation agencies.

Plantskydd Deer Repellent is made in the USA and is a 100% natural, environmentally friendly product. Plantskydd Soluble Powder Concentrate is 'Listed' by the Organic Materials Review Institute (OMRI - trw-9589). Plantskydd is member tested and recommended by the National Home Gardening Club.

Plantskydd Deer Repellent was initially developed in Sweden in 1991 in response to commercial forest plantations being decimated by plant eating mammals. The forest industry needed an animal repellent that could last through severe weather and meet Sweden's strict environmental laws. Plantskydd's long-term effectiveness is attributable to the tenacity of its 100% natural, vegetable oil binder in sticking to plants, even under severe snow/rainfall conditions: up to 6 months over winter, 3-4 months in summer. The Swedish name for the product "Plantskydd" translates as "Plant Protection".

Plantskydd Deer Repellent works by emitting an odor that animals associate with predator activity, repelling the animal before it nibbles on plants. Research has proven that odor-based repellents are more effective than other repellent systems where the animal needs to taste treated plants before being repelled. Once animals are attracted to an area and begin feeding, it is more difficult to discourage them from returning. Plantskydd stimulates a fear-based response which will have deer, elk, moose, opossum, and rabbits looking to dine somewhere other than your garden or plantation.

Plantskydd® Deer Repellent is the browse deterrent of choice for leading North American forest companies who use it to successfully prevent plantation damage by deer, rabbits, elk and moose to millions of conifer and hardwood trees, including: cedar, spruce, fir, pine, alder, birch, larch, and poplar species. Many customers have provided positive anecdotal feedback as to the effectiveness of Plantskydd in protecting plants against other herbivores (plant eating mammals).

Nurseries and landscapers find Plantskydd® Deer Repellent to be equally effective in protecting flowers, shrubs, and ornamentals.

Which repellents actually work ?

" ...Studies investigating trends in efficacy of deer repellents indicate that, of the 20 products tested, repellents with active ingredients that emitted sulfurous odors i.e.: bloodmeal or egg solids, generally provided the best results..."

"...Products that contained active ingredients which cause pain/irritation (capsaicin, allyl isothiocyanate), or illness (thiram) were less effective..."

"...Products that use a bitter taste (denatonium benzoate) were usually the least effective in reducing damage by herbivores. Repellents that were applied to plant surfaces were generally more effective than capsules or other devices that produced an odor intended to protect a specific area."

Plantskydd's Development

Plantskydd® Deer Repellent 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.

100% Natural

The formulations- Plantskydd powder concentrate (trw-9589) and Plantskydd granular (trw-731) are Listed by the Organic Material Review Institute (OMRI) as suitable for use in the production of organic food and fibre.

Plantskydd is exempt from federal EPA (Environmental Protection Agency) pesticide registration. Plantskydd contains no synthetic additives, is non-toxic and is not harmful to animals, plants or the environment.

The 'active' ingredient is dried blood (porcine and/or bovine)- recognized by the EPA as an environmentally safe ingredient.

In the United States, *bloodmeal* is an EPA (Environmental Protection Agency) exempted product/minimum risk pesticide and is exempt from the Federal Insecticide, Fungicide, and Rodenticide Act requirements, specifically under Section 25(b) c.f. Federal Register, 61(45), Mar. 6, 1996 and therefore is not subject to federal registration.

"The EPA has determined ... that the use of these pesticides poses insignificant risks to human health or the environment ...
"The Agency in promulgating this rule, is responding to society's increasing demand for more natural and benign methods of pest control ... "
May 6, 1996 USA — EPA

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.

Fertilizing Effects

As an added benefit, Plantskydd Deer Repellent acts as a foliar feed fertilizer for many types of plants. Bloodmeal, Plantskydd's active ingredient, has long been recognized as an organic fertilizer. Studies performed by Pennsylvania State University showed that the use of Plantskydd on a variety of flowering plants resulted in a fertilizing effect.

"All plants tested that were treated with Plantskydd were larger, had more flowers and generally had greener leaves. This response is typical of the response created by an increased level of fertilization."

Can I use Plantskydd on my vegetable garden?

Yes! Plantskydd is safe for use in protecting fruit, vegetables and other food crops against animal browse damage. Plantskydd’s soluble powder concentrate formulation was the first animal repellent to be ‘OMRI Listed’ (trw-9589) by the Organic Materials Review Institute as “suitable for use in the production of organic food and fiber.” NEW Granular Plantskydd is also ‘OMRI Listed’ (trw-731) and USDA approved for organic gardening.

Why does Plantskydd work so well?

Animals avoid plants before they bite—not after! Plantskydd repels by emitting an odor (not unpleasant to applicators) browsing animals associate with predator activity—stimulating a fear-based response that will have garden feeders looking for somewhere else to dine. Research proven more effective than other repellent systems.

Advances and Challenges in Forest Regeneration (2000)

Over 50+ Field Tests* conducted in Canada and the USA since 1994, by foresters, professional growers and landscapers confirmed Plantskydd’s unmatched plant protection efficacy against: deer, elk, moose, and rabbits.   NEW Granular Plantskydd is proven effective against: rabbits, voles, squirrels, chipmunks, hares, nutria, opossum and other small critters—as well as deer and elk.

How often do I need to treat my plants and trees?

• For best protection, treat plants before browse begins in spring or fall.
• Plantskydd powder concentrate lasts up to 6 months over winter on dormant plants, and 3-4 months during the active growing season.
• IMPORTANT—spray liquid Plantskydd on dry plants—allow to dry thoroughly for at least 24 hours.
• With proper application, Plantskydd is rain-resistant and does not require re-application after watering or rainfall.
• Always treat new growth —until plant has reached full size or leaf-out.
• Ideally, liquid Plantskydd is sprayed in the morning, or late afternoon, when the sun is not as strong.
• Granular Plantskydd may be applied at anytime. Re-treat as required.

How should I store Plantskydd?

Protect from heat. Store in cool, dry, dark location. Keep from freezing.

• GRANULAR —lasts 5+ years when stored as directed.

• READY-TO-USE LIQUID —use within 3 months of opening the sealed container. Apply unused solution as a fertilizer.

• SOLUBLE POWDER CONCENTRATE —in its original packaging, the concentrate lasts 5+ years. Tightly re-seal unused powder. Plantskydd is a 100% natural product and will start to go off in warm weather. Once mixed into solution, use within a few days. Apply unused solution as a fertilizer.

Will Plantskydd hurt my dog?

Some users have reported that the family dog is quite enamoured withPlantskydd when it is sprayed and still wet on the plants. It will not harm animals, but it’s best to leave Fido inside until the treated plants are dry.

How can I protect fruit trees?

Treat prior to, or 2-3 weeks after bud-flush. Avoid treatment while buds are forming. Treatment over foliage is enough to deter browsing herbivores.

Whips—if you’re planting young fruit tree whips, dip them in Plantskydd solution before planting, or try coating the whip using a paint brush. Then spray trees when the leaves have formed.

Any plants I should avoid treating with Plantskydd?

Plantskydd will darken leaves temporarily. They return to their normal color in a couple of days. We suggest you test samples of sensitive plants (e.g., roses) before treating large numbers. If leaves curl on test plants, rinse with a fine spray of water and dilute Plantskydd solution further. To prevent leaf curl, water plants well at the roots before treatment.

Note: For aesthetic reasons, use of a concentrated solution on very fuzzy leaves like Santolina, Lamb’s Ear and Lavender is not recommended—dilute solution using more water if necessary. Fortunately, these plants are usually not preferred by our furry friends.
