Abstract

What is described is a composition with long-lasting repellent action for protection of plants against damage by animals containing a hydrophobic carrier, repellent substances, additive auxiliary substances and, if desired, colouring additives. Further described is a method of preparation of this composition.

Description

Composition w th long-lasting repellent action for protection of plants
Technical Field
The invention relates to an agent for protection of plants against damage by animals.
Background Art
Animals, by biting off sprouts of seedlings, young trees and by peeling off bark of trees, cause considerable economic damages. That is why the plants are protected, inter alia, by repellent agents, which deter the animals.
The drawback of the prior art repellents is their environmental unsoundness. Many of them contain, as active components, organic pesticides, organic solvents, waste bitumens etc., and have properties inconvenient for handling, such as flowing off the treated surfaces, being difficult to remove from the equipment used, and the like.
An useful solution consists particularly in orientation at repellents based on natural substances, easy to biodegrade into harmless products compatible with the environment.
The first group includes repellents containing, e.g., kaolin, tall oil, emulsifiers, acrylates, thiuram disulphide, and the like. The second group is based on generally Known repellent action of certain waste animal products such as lanolin (FCH 601 tested as early as n 1956) and similar.
Description of the Invention
It has now been found that a high repellent action may be achieved by releasing a mixture of scents bound on a hydrophobic carrier. These scents originating from waste plant and animal products are stabilised in a conveniently applicable environment, which is achieved by mixing a suitable ratio of rape-seed oil methyl ester (hereinafter referred to as ROME) , resin with an emulsifier, lanolin and, if desired, fats.
By changing the ratio of the components it is possible to purposefully modify the consistency of the agent from a paste to a spray form, as required by the particular application, while maintaining good applicability, adhesiveness and duration of action.
The mixture of ROME, emulsifier, lanolin, resin and, if desired, fats after thermal processing will create a mass serving as a carrier of repellent substances.
This carrier, preferably of pasty consistency, is prepared after homogenisation of the components at elevated temperature, at which structural polymerisation reactions take place, in particular, heteropolycondensation of resins and their components (vinyl resins - PVA, resinous acids and their esters - abietic acid, dehydroabietic acid, levopimaric acid, palustric acid and their glycerides) with reactive substances of lipidic components (ROME, lanolin) such as fatty acids (unsaturated, polyhydric and the like, oleic acid, elaidic acid) and their esters (mono-, di- and tri- acylglycerols) and the like. Mixture thus processed fixes the scent components in an increased extent and thereby prolongs the repellent effect of the composition. At the same time, it increases adhesion and climatic resistance of the resulting product .
Particular repellent substances that may be used include the fat-protein emulsion (FPE) , meat-bone fat, garlic preparations (essential oil, extracts and juices) , natural mercaptans and thiols, natural plant terpenes and resins, if desired, with added stabilisers, colour markers, etc.
Additive auxiliary substances include preparations with active surface based on zeolites or amorphous silica (Siloxid, Mikrosil and the like) , anti-freezing agents (glycol, glycerol, and the like) . At the same time, these substances serve as pigment carriers. An advantage of the composition according to invention is the fact that it can be applied also m rainy weather and at temperature around the freezing point.
