Abstract
CHEMICAL COMPOUNDS COMPRESSED IN PILL FORM TO DISCOURAGE DAMAGE BY BROWSING,GRAZING AND GNAWING ANIMALS AND BIRDS.
Description
r 2 n ~ 3 a~
TABLET FORMULATION TO DETER ANIMALS FROM EATING AND/OR
BROWSING ON TREE SEEDLINGS AND OTHER PLANT LIFE
This invention relates to a combination of chemicals and compounds in a tablet form that will by systemic uptake through the roots cause trees and plants to become bitter and distasteful.
There are a number of m~mm~l s/bird in every forest. Many of these animals are beneficial, assisting in the dispersal of seeds and important fungi, devouring insects and contributing to the recreational and economic value of the forests. However, a number of these bird and m~mm~l species inflict serious damage to both seedlings and more mature trees. This damage takes the form of consumption and uprooting of seedlings, gnawing and stripping of bark, removal of foliage and clipping of twigs. Such damage can delay forest maturation, alter species composition, cause later deformation of adult trees, and in general drastically increase the cost of forest planting and maintenance, while decreasing the value of harvested lumber.
A number of techniques have been used to control or prevent animal damage to forest plantations. The effectiveness of any technique depended on:
~ How well it is applied.
~ How appropriate it is for the situation.
~ The availability of alternate food sources to the damaging animal.
~ How desirable these alternate food sources are relative to the trees being protected.
Damage may be prevented by excluding the offending animals from the plantation. Fencing has been tried, but it is expensive in materials and labour, and requires regular inspection and maintenance. In some cases, the deer/elk can jump over the fence itself.

Plastic mesh tubing has been used to protect seedlings from damage by small animals. Velar tubing has been tested, with leader (main shoot) placement, with some reduction of damage. Browsing to lateral branches was not deterred.
In another test case, wax paper was clipped to the leader of trees in an effort to discourage browsing. There was some reduction in damage, but upon emergence from the wax paper, the leader became vulnerable to browsing damage again.
Other test methods include the use of milk cartons placed over the top of seedlings, and cardboard cylinders with moth balls. Both trials were unsuccessful.
Sprayed liquid or dusted powder repellents have been used to discourage animals from feeding/browsing on seedlings in the past. However, effectiveness is limited due to low residency and the washing effect of rainfall and dew.
Other ideas for decreased damage include the use of alternate forage of a more suitable type. However, this food stuff would have to be available all year round and would greatly add to the cost of forest replanting programs.
Another animal that is causing serious concern are the voles. Damage consists of barking and cambium injuries to the stems, branches and roots of Douglas Fir, Western White Pine and Cottonwood seedlings. Protection methods against this pest consist mainly of wrapping the stems or trunks with a variety of materials ranging from tin foil through plastic and hardware mesh. These methods are all very expensive.
All current research reports and publications indicate that seedlings and more mature trees are not normally the preferred food stuff. However, when forced by lack of more suitable food, and population pressures, browsing and gnawing animals will consume all or portions of many species ~; of seedling trees.

In British Columbia alone, the amount of damage is estimated by Forest management Organizations, to be anywhere between 30~-100~ (Queen Charlottes) of total plantings. Protection and/or replanting can nearly double the cost per seedling per hectacre.
A method of decreasing this damage, the main object of the present invention, involves the application of leach-resistant tablets that slowly release browsing deterrents into the root system of susceptible seedlings, plants and ornamental shrubbery. This tablet can be applied during initial growth in tree farms, or at the time of transplanting into the field.
Another object is to provide a tablet which is totally biodegradable, non-phytotoxic and contains fertilizers that promote seedling, plant or shrubbery growth in the first crucial year of growth.
According to one aspect of the present invention, there is provided an anti-browsing tablet weighing at least one-half gramme, for slowly feeding susceptible seedlings of at least one of conifers, deciduous trees, shrubbery and ornamental plants at least during the first crucial year of growth, and consisting of a tableted intimate mixture of solid particles comprising, at least one browsing-deterrent substance, in an amount of up to about 12.0~ by weight of the tablet, the effect of which is to impart a bitter or unpleasant taste to the seedlings by systemic uptake, and a combination of N-P-K based fertilisers in an amount sufficient for promotion of growth of a selected one of said seedlings during at least said first year.
According to another aspect, this invention relates to a method of controlling animal browsing/gnawing on seedlings of at least one of deciduous trees, shrubbery and ornamental plants at least during the first crucial year of growth, comprising placing into the root zone at least one tablet of the present invention at the time of planting or transplanting said seedlings.

4 ~ 2 0 0 0 6 3 ~ ' This substance is known to be the most bitter substance available to man. It is currently used as a deterrent, in toxic substances, to avoid accidental ingestion. This fact, along with its total solubility in cold water, allows systemic uptake and resulting bitter tasting foliage. At the same time, this substance has a very low toxicity, as seen by LDso (rat) of 584 mg/kg body weight.
Within the above class of deterrent compounds, other compounds such as the Quaternary Salts of Organic Carboxylic Anions with a Quaternary Organic Ammonium Cation of the general formula:
(I) CH3 ~ R1 may be applied as stated herein earlier in a tablet form to produce the desired bitter or unpleasant taste. Preferred bitter substances are those quaternary organic carboxylates represented by the general formula:

According to the second object of the present invention, the incorporation of specific fertilizers, are present to increase the growth of transplanted seedlings during the first crucial year of growth.
The present invention provides a long-lasting, slowly soluble fertilizer composition 18-6-12, tableted with the aid of a water-soluble binder, which dissolves readily when water is applied, so that the tablet breaks up easily.
The 18-6-12 composition is available specifically for conifers and for all other botanical applications. For other than conifer, the basic fertilizer composition would lnvolve:
~ by weight UREA (45-0-0) 38.0 MURIATE OF POTASH (0-0-62) 19.30 TRIPLE PHOSPHATE (0-45-0) 13.30 BINDERS, DETERRENTS, ETC 29.4 TOTAL 100~
Since most conifers are unable to properly metabolize urea as a nitrogen source, plus the increased growth of various root rotting fungi on urea; the following 18-6-12 fertilizer composition for conifers is used:
~ by weight AMMONIUM NITRATE (34-0-0) 45-9 MURIATE OF POTASH (0-0-62) 19.3 DIAMMONIUM PHOSPHATE (21-53-0) 11.3 BINDERS, DETERRENTS ETC 23.5 -9 ~ 3 ~
This combination of compounds produces a totally water-soluble fertilizer composition that is available to the seedlings almost immediately upon rainfall. For a longer lasting fertilizer, the following would be used:
~ by weight AMMONIUM NITRATE (34-0-0) 52.9 MURIATE OF POTASH (0-0-62) 19.3 TRIPLE SUPER PHOSPHATE (0-45-0) 13.3 10 BINDERS, DETERRENTS ETC 14.5 TOTAL 100~
According to another aspect of this invention, there is a need for a lubrication ingredient to continually protect from abrasive wear, the metal surfaces of the tableting equipment that come in contact with the materials being tableted, to facilitate the compression of the tablets, and to enable proper extraction of the tablets from the dies in which the tablets are formed. At the same time, this material must not waterproof the tablet. The preferred material here is talc.

The composition is thoroughly mixed dry and then is pelleted dry into tablets, which may be from 1/2 gram to about 30 grams in size. The talc acts as a tablet lubricant during manufacture, ensuring release from the tableting cavity without acting to water proof the tablet.
The above formula is a scientifically balanced low-toxicity plant fertilizer/deterrent tablet with long-lasting characteristics that meet the problems of animal browsing on deciduous trees, shrubbery and ornamental plants.
