BACKGROUND OF THE INVENTION The present invention relates to a repellent composition for the protection of plants, forest and fruit crops, preventing the bite and bite of game during the vegetation period, in particular during the vegetative period of rest.

Background

So far known repellents for the protection of plants, forest and fruit crops, preventing bite and game bites are made of titanium dioxide, floated kaolin, rosin, thal oil, waste sulfoacids after processing fish waste, alcohol, xylene, emulsifiers, dyes, ammonia water , water glass, carboximethylcellulose, propane asphalt, acrylate dispersions, benzoic acid, isopropyl alcohol, thiourandisulfite and other substances. The disadvantage of the repellent preparations known hitherto is their ecological unsuitability, which depends on the chemicals and fillers used. Another disadvantage is their application only to dry plants and dry forest and fruit crops. Another disadvantage of these known formulations is the impossibility of their application in the period of rain, fog and dew. Their disadvantage is also their low or no frost resistance. If the temperature of the mixture drops below 0 ° C, they become deteriorated. A further disadvantage of the repellent compositions known to date is that if rainfall occurs during their application or after application and before the product dries, the product loses its effect.

SUMMARY OF THE INVENTION

Disadvantages of the prior art are largely eliminated by the repellent plant, forest and fruit crop protection composition according to the invention, characterized in that the composition comprises wool wax and preferably contains from 4% to 45% by weight of wool wax, composed of from a mixture of esters of higher fatty acids and alcohols and from 19% to 96% by weight of a mixture of higher fatty acids, predominantly oleic acid. Repellent product

according to the invention, it may also contain 10% to 67% of a filler, such as limestone limestone or floated kaolin and / or ethyl alcohol or water.

The characteristic odor of wool wax, which is obtained by cleaning sweat sheep wool, repels the game and thus protects plants, forest and fruit crops from bite and bite. Wax wax is a natural animal raw material and is environmentally friendly.

DETAILED DESCRIPTION OF THE INVENTION

The wool wax, composed of a mixture of esters of higher fatty acids and alcohols, obtained as a waste product from sweat sheep wool cleaning, is transferred from the solid phase to the liquid phase by heating. While stirring, vegetable or animal oils and fats are added uniformly to the liquid phase of the wool wax at a temperature of 38 ° C to 80 ° C. It is preferred to add waste products resulting from the production of vegetable and animal oils and fats. It is particularly preferred to add a 20 to 50 ° C warm mixture of higher fatty acids with a predominance of oleic acid, in a weight ratio of 4% to 45% of a mixture of esters of higher fatty acids and alcohols, and 19% to 96% . After addition of the prescribed amount by weight, the mixture is stirred for a further 5 minutes. Subsequent filtration then prepares the base mixture into which the fillers and water are incorporated by stirring.

Example 1

Even mixing of 75% by weight of a mixture of higher fatty acids with a predominant oleic acid temperature of 25 ° C to 60 ° C to 25% by weight of a mixture of higher fatty acid esters and alcohols of 25 ° C to 60 ° C results in a liquid repellent mixture. plants, forest and fruit crops by spraying or painting.

Example 2

Stirring 19% by weight of a mixture of higher fatty acids with a predominant oleic acid temperature of 25 ° C to 60 ° C

6% by weight of a mixture of higher fatty acid esters and alcohols at a temperature of 25 ° C to 60 ° C results in a liquid repellent mixture to which 67% by weight of ground limestone is uniformly added while stirring. After the prescribed weight percent of ground limestone has been added, stirring is continued for a minimum of 30 minutes until the mixture is homogeneous. If carbon dioxide is leaking from the mixture, stirring is continued until no CO2 is released from the mixture. Up to 8% by weight of water is then added uniformly while stirring. Stirring is continued until all the water is quantitatively incorporated into the mixture. The resulting repellent composition can be applied to plants, forest and fruit crops by coating.

Example 3

Stirring 19% by weight of a mixture of higher fatty acids with a predominant oleic acid temperature of 25 ° C to 60 ° C to 6% by weight of a mixture of higher fatty acid esters and alcohols at a temperature of 25 ° C to 60 ° C results in a liquid repellent mixture. stirring, adds 67% by weight of the floated kaolin evenly. After addition of the prescribed weight percent of floated kaolin, stirring is continued for at least 30 minutes until the mixture is homogeneous. If carbon dioxide is leaking from the mixture, stirring is continued until no CO ₂ is leaking from the mixture. Stirring is continued until all the water is quantitatively incorporated into the mixture. The resulting repellent composition can be applied to plants, forest and fruit crops by coating.

Example 4

Even mixing of 65% by weight of a mixture of higher fatty acids with a predominant oleic acid temperature of 25 ° C to 60 ° C to 25% by weight of a mixture of higher fatty acid esters and alcohols of 25 ° C to 60 ° C results in a liquid repellent mixture. stirring, it adds 10% by weight of ethyl alcohol evenly. The resulting homogeneous liquid repellent composition can be applied to plants, forest and fruit crops by spraying or painting.

maura

The advantage of such repellent preparations, containing mainly a mixture of esters of higher fatty acids and alcohols, is the possibility of their application in rain, fog and dew and also application on wet cultures. Another advantage is their resistance to frost. They are not impaired. A further advantage of the repellent compositions thus produced is their resistance to moisture and rain before they dry.

Industrial applicability

The repellent preparation according to the invention is intended primarily for the treatment of plants, forest and fruit crops in the wild and in orchards, but if desired, its use can be much wider, making it a means of general agrotechnology.

The repellent formulation of the invention can be industrially produced.
