Description

The present invention relates to a wild-type repellent composition containing denatured blood meal as an active ingredient.

The preparation is spray-proof, rain-resistant and non-phytotoxic. Used to alert small and large game.

It is known that wild crops cause serious damage to arable crops, nurseries and new afforestations. They are particularly damaging to new plantations to replace deforestation caused by acid rain by chewing the trees of the forests as they cause their destruction.

There is also a great deal of damage to arable crops due to the destruction caused by wild chewing and game trapping, and the loss of yield.

Many methods and preparations for preventing and overcoming the damage caused by wild chewing are known and used, but so far there has not been a sufficiently economical and effective way to prevent wild damage.

Some of the commercially available repellents are active in tar (anthracene oil, tar, acridine bases, etc.). They are phytotoxic substances and therefore not applicable during the vegetation period, and are well known to cause skin irritation and carcinogenicity in humans.

Other known formulations contain wild-type repellents in the form of a lubricating paste. These agents should be applied in such a way that trees and saplings have to be applied individually, which is a very labor-intensive operation and is therefore not widely practiced.

Other wild-type repellents are marketed in the form of wettable powder formulations. They can be sprayed diluted with water and are therefore suitable for large areas. However, the well-known drawback of wettable powder formulations is that the spray coating is not rain-resistant, and therefore such agents should be repeated weekly. This makes defense very expensive, making it uneconomical to overcome.

Similarly, because of their cost, wild-type repellents containing antibiotics (eg, extract of strains of Streptomycin) or sex hormones (androsterone) have not spread.

Such formulations are disclosed in U.S. Patent Nos. 3,043,743 and 4,534,976, respectively.

Preparations containing plant extracts or vegetable oils as active ingredients are also widespread.

French Patent Specifications A2 495 469 and Brazilian Patent Publication 7 904 243 disclose a composition for repelling animals which contains the active ingredient in paprika extract (capsaicin).

An extract of the seed of anise dust (Foeniculum vulgare) is contained in an alarm composition as disclosed in French Patent Publication No. 2,527,902, while PCT Publication No. 8,505,009 recommends an encapsulated preparation containing wormwood oil for repelling wildlife.

The disadvantages of each of the compositions described are that they are not effective enough to be used in large-scale agricultural and forestry applications.

It is an object of the present invention to provide a composition for overcoming the above deficiencies.

Experiments were conducted with a composition containing denatured blood meal as an active ingredient.

The present invention provides a composition comprising 3 to 60 parts by weight of denatured blood meal, 97 to 40 parts by weight of an aqueous solution of ammonium caseinate - 15 to 30% by weight, and up to 10 parts by weight of zinc dimethyldithiocarbamate and / or tetramethylthiuram disulfide; optionally containing 100 parts by weight of water.

The colloidal dispersion thus produced can be applied by spraying or spraying, rain resistant and non phytotoxic. It is very effective in repelling game, after several weeks of rainfall.

In contrast, if we found powdered blood in itself, dust was applied to the area to be protected - the wild-scare effect disappears within a few days.

The following examples illustrate the preparation and preparation of the present invention.

Example 1

100 parts by weight of casein are suspended in 600 parts by weight of water. The suspension is warmed to 35 ° C and ammonium hydroxide is added with stirring until a clear solution is obtained.

80 parts by weight of the solution thus prepared are mixed with 20 parts by weight of denatured blood meal.

The homogenized preparation is brushed without dilution onto the trunks to be protected.

Example 2

Example 1 is repeated, but 3 parts by weight of denatured blood meal are mixed with 97 parts by weight of aqueous ammonium caseinate solution,

The composition is used for spraying.

Example 3

An ammonium caseinate solution was prepared as described in Example 1 from 100 parts by weight of casein and 400 parts by weight of water.

To 80 parts by weight of the solution was added 12 parts by weight of denatured blood meal and 4 parts by weight of zinc dimethyldithiocarbamate and 4 parts by weight of tetramethylthiuram disulphide.

The homogenized mixture is applied by brush to the trunk of trees.

Example 4

In Example 3, 55 parts by weight of flour and 1 part by weight of zinc dimethyldithiocarbamate were added to 46 parts by weight of ammonium caseinate.

The homogenized composition thus obtained is formulated in containers.

Before use, 100 parts by weight are diluted with 100 parts by weight of water and the diluted product is applied by brush to the surface to be protected.

Example 5

All proceed as in Example 4 but using tetramethylthiurane-2HU 202717Β disulfide instead of zinc 65 dimethyldithiocarbamate.

Example 6 Annual plantation forest is sprayed with the composition of Example 2. Four months after spraying, test for chewing and sticking! clues. No traces of Hyen were found.

As a control, another 1-year-old forest was dusted with ground blood meal. Four months after pollination, the chewing and adherence was examined.

30% of the trees showed traces of wild chew and adhesion.
