SK278824B6 - Repellent agent for plant protection, forest and fruit cultures - Google Patents

Abstract

The repellent agent contains 4 up to 4,5 weight percent of wool wax, created based on the mixture closed to esters of higher fat acids and alcohol, 19 up to 96 weight percent of higher fat acids, where oleic acid ascendance is observed, 10 up to 67 weight percent of filler, while milled limestone, washed clay can be applied for these purposes, however it can contain ethanol of 8 weight percent of water. This agent is applied in order to prevent the plants, wood and fruit cultures to be bitten by animals

Description

Technical field

The invention relates to an insect repellent composition for the protection of plants, forest and fruit crops to prevent bite-biting in the period of vegetation, in particular in the period of vegetative rest.

BACKGROUND OF THE INVENTION

So far known repellents for the protection of plants, forest and fruit crops to prevent animal bites are made of titanium white, floated kaolin, tall oil, waste sulfoacids after processing fish waste, alcohol, xylene, emulsifiers, dyes, ammonia water, water glass, carboxylate , 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 fillers 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

Disadvantages of the prior art are largely eliminated by the repellent plant protection, forest and fruit crops preventing animal bite, which is based on the fact that wool wax is present in the preparation. 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 of the invention may also contain 10% to 67% 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. 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 transferred 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 a temperature of 38-80 ° 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 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

Mixing 75% 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 higher fatty acid esters and alcohols at a temperature of 25 to 60 ° C evenly forms a liquid repellent mixture which can be applied to plants , 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 higher fatty acid esters and alcohols with a temperature of 25 to 60 ° C results in a liquid repellent mixture. adds 67% by weight of ground limestone. 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 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

Mixing 19% by weight 35 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 uniformly mixes into a liquid repellent mixture. it evenly adds 67% 40 wt. 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 escapes 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 higher fatty acid esters and alcohols at a temperature of 25 to 60 ° C, a liquid repellent mixture is formed. 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 coating.

The advantage of the repellents produced in this way, containing mainly a mixture of esters of higher fatty acids and alcohols, is the possibility of their application in rain, fog and rose as well as application to wet cultures. 65 Another advantage is their frost resistance. They do not deteriorate. A further advantage of the repellents produced in this way is their resistance to moisture and rain before they dry.

Industrial usability

The repellent formulation 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 agrotechnology.

The repellent preparation can be manufactured industrially.
