Description

Repellent for the protection of plants, forest and fruit crops

Technical field

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

BACKGROUND OF THE INVENTION

So far known repellents for the protection of plants, forest and fruit crops preventing bite and game bite are made from titanium bleach, floated kaolin, tall oil, waste sulfoacids after processing fish waste, alcohol, xylene, emulsifiers, dyes, ammonia water, water glass, carboxymethylene 1 in 1ose, propane asphalt, acrylate dispersions, benzoic acid, isopropyl alcohol, thiouran disulfite and other substances. A disadvantage of the repellent preparations known hitherto is their ecological unsuitability depending on the chemicals and substances used. Their further disadvantage is the application only to dry forest and fruit crops. Another disadvantage is also their low or no frost resistance. If the temperature of the mixture falls below 0 ° C, these formulations are degraded. A further disadvantage of the repellent compositions known hitherto is that if they occur during or after application and before the composition dries to rain, the composition loses its effect.

SUMMARY OF THE INVENTION

The disadvantages of the prior art are largely eliminated by the repellent plant, forest and fruit protection product which prevents the bite and the bite from being bred, which is based on the fact that the preparation contains wool wax. The repellent composition preferably comprises from 4% to 45% by weight of wool wax composed of 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. The repellent composition according to the invention may also contain 10 ΐ to 67 K filler, such as ground limestone or floated kaolin, and also ethyl alcohol or water.

The characteristic odor of wool wax, which is obtained by cleaning sheep wool, repels animals and thus protects plants, forest and fruit crops from biting and biting. Wool wool 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 sweeping sheep wool, is converted from the solid phase to the liquid phase by heating. While stirring, vegetable or animal oils and fats are slowly added to the liquid phase of the wool wax at 38-80 ° C. It is preferable 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 fatty acid mixture with a predominant oleic acid content of 4% to 45% by weight of a mixture of higher fatty acid esters and alcohols and a 19% to 96% higher fatty acid mixture with a predominant oleic acid. After addition of the prescribed amount by weight, the mixture is stirred for a further 5 minutes. Subsequent filtration then prepares a masterbatch into which the fillers and water are mixed.

Example 1

By uniformly mixing 75% by weight of a mixture of higher fatty acids predominantly oleic acid at a temperature of 25 to 60 ° C to a 25% by weight mixture of higher fatty acid esters and alcohols at a temperature of 25 to 60 ° C, a liquid repellent mixture can be applied. , forest and fruit crops by spraying or coating.

Example 2

Stirring 19% by weight of a mixture of higher fatty acids predominantly oleic acid at a temperature of 25 to 60 ° C to 6% by weight of a mixture of esters of higher fatty acids and alcohol at a temperature of 25 to 60 ° C results in a liquid repellent mixture to which 67% by weight of ground limestone. After the prescribed weight percent of ground limestone has been added, stirring is continued for at least 30 minutes until the mixture is homogeneous. If the carbon dioxide escapes from the mixture, stirring is continued until no more carbon dioxide escapes from the mixture. Up to 8% by weight of water are then added uniformly with stirring. Stirring is continued until all the water has been quantitatively incorporated into the mixture. The resulting repellent composition can be applied to plants, forest and fruit crops by coating.

Example 3

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

Example 4

By uniformly mixing 65% by weight of a mixture of higher fatty acids predominantly oleic acid at a temperature of 25 to 60 ° C to 25% by weight of a mixture of esters of higher fatty acids and alcohols at a temperature of 25 to 60 ° C adds 10% by weight of ethyl alcohol. The resulting homogeneous liquid repellent composition can be applied to plants, forest and fruit crops by spraying or coating.

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

Industrial usability

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

The repellent preparation can be manufactured industrially.
