Description

A composition with a long-lasting repellent effect for the protection of plants against animal damage and a process for its preparation

Technical field

The present invention relates to a plant protection product against animal damage.

BACKGROUND OF THE INVENTION

The beasts of seedlings, young trees and peeling of the bark of woody plants cause multimillion-dollar damage. Therefore, they are protected, inter alia, by repellent products which repel animals.

The disadvantage of existing repellents is their ecological unsuitability. Many contain as active ingredients organic pesticides, organic solvents, waste asphalts and the like. and have unsuitable handling characteristics such as sagging, difficult removability from auxiliary equipment, etc.

Perspective is especially the orientation on repellents based on natural substances, easily biodegradable to harmless products compatible with the environment.

From the first group, repellents are known which contain e.g. kaolin, tall oil, emulsifiers, acrylates, tiuram disulfide and the like. . The second group is based on the well-known repellent effects of some animal waste products such as e.g. lanolin (FCH 601 tested already in 1956) and the like.

SUMMARY OF THE INVENTION

It has now been found that a high repellent effect can be achieved by releasing a mixture of odors bound to a hydrophobic carrier. These odorous substances derived from waste plant and animal products are stabilized in a well-usable environment by mixing a suitable ratio of rapeseed oil methyl ester (hereinafter referred to as MERO), an emulsifier resin and the addition of lanolin and optionally fats.

By varying the component ratio, the consistency of the formulation can be conveniently varied, from paste to spray form, as required by application practice, while maintaining good applicability, adhesion and duration of action.

The mixture of MERO, emulsifier, lanolin, resin and possibly fats after heat treatment forms a mass that serves as a carrier for repellents.

This carrier, preferably pasty, is prepared after homogenization of the components at elevated temperature at which construction polyreactions are carried out, in particular heteropolycondensation of the resins and their components (vinyl resins - PVA, bituminous acids and their esters abietic, dehydroabietic, levopimaric, palustric and their glycerides ) with reactive substances of lipid components (MERO, lanolin) such as fatty acids (unsaturated, polybasic and the like, oleic, elaidic) and their esters (mono-, di- and triacylglycerols) and the like. The mixture thus treated increases the odor components to an increased extent and thereby prolongs the repellent effect of the composition. At the same time it increases the adhesion and climatic resistance of the final product.

Particularly repellent substances may be fat-protein emulsion (TBE), butter-bone fat, garlic preparations (silica, extracts and pomace), natural mercaptans and thiols, natural plant terpenes and resins, optionally supplemented with stabilizers, color markers and the like.

Active surface preparations based on zeolites or amorphous silica (Si-oxide, Mikrosil and the like), so-called " "Anti-freezing agents (glycol, glycerol, etc.). These substances also serve as carrier for the dye.

An advantage of the composition of the invention is that it can also be applied in rainy weather and at temperatures around zero.

Example 4

Carrier preparation:

The heated lanolin is mixed with MERO and an emulsifier (temperature above 70 ° C). After mixing, the resin is added and stirred vigorously at 110 ° C for 120 minutes. After cooling to 35-40 ° C, a pasty carrier suitable for fixing odor components is obtained.

Example 5

Carrier preparation:

The heated lanolin is mixed with MERO and emulsifier and PVA (temperature above 70 ° C). After mixing, the resin is added and stirred vigorously at 110 ° C for 120 minutes. After cooling to 35-40 ° C, a base carrier suitable for fixing the odor components for the spray formulation is obtained.

Example 6

Composition of the composition in ml:

carrier (example 1) 714 TBE 98 ethanol 6 dye 1 water 55 microsil 60 oleum terebinthinae 1 oleum alii 5

The carrier is heated to 60 ° C and TBE is added. After cooling to 35-40 ° C, a color marker is added with stirring (the dye is dissolved in ethanol, diluted with water and applied to Microsil with stirring). Finally, essential oils are added.

Example 7

Composition of the composition in ml:

carrier (example 3) 480 TBE 4 0 ethanol 6 dye 1 silica 10 oleum terebinthinae 1 oleum resinatum 1 oleum alii 5 emulsion stabilizer 6 water 450

The carrier is heated to 60 ° C and TBE is added. After cooling to 35-40 ° C and stirring, a color marker is added (the dye is dissolved in ethanol, diluted with water and applied to Microsil with stirring) and essential oils are added.

With vigorous stirring, the composition is gradually added to the aqueous solution of the emulsion stabilizer until a syrupy consistency is obtained. The finished product is well diluted with water and suitable for spray application.

Example 10

The biological activity of the composition (Example 8) was verified under operating conditions in spruce, fir, beech, ash and maple stands of 0.5 ha. 100 pieces of each tree were treated. Cervakol extra, manufactured by Avenarius Chemische Fabrik GmbH was used as standard. The control was the remainder of the stand without treatment. The composition to be tested was applied by hand, with a rubber glove, as a fine discontinuous spot coating on young shoots during October. The sites represented habitats with extreme pressure on the woody component during the winter months 1997/98 and 1998/99. The damage to the terminal shoots of the untreated control ranged from 29 to 94.1% on average 68.2%. The average efficacy of the new composition over a two-year period on five trees was 90%. The benchmark achieved 37% efficiency under the given conditions. The effect of the new composition persisted even in the summer months without adverse effects on protected tree species.

Example 11

The biological efficacy of the preparation (Example 7) was verified under operating conditions in spruce, fir, beech, ash and maple stands of 0.5 ha. 100 pieces of each tree were treated. The control was the remainder of the stand without treatment. The test formulation was applied with a spray applicator as a fine continuous film to young shoots at the end of August and during September. The damage to the terminal shoots of the untreated control ranged from 76.3 to 81.1%, on average 78.7%. The average damage after treatment with the product over two years in five tree species was from 9.9 to 14.6, on average 12.4%.
