The present invention relates to an insecticidal insecticidal mixture intended for the treatment of green plants. These nutrients can be water-soluble nitrogen, phosphorus and potassium-containing salts or biological materials, such as are preferred, for example, in biodynamic cultures.

Organic fertilizers generally must first be dissolved before use in the current mixture, then filtered. For destruction of harmful microorganisms, it may be desirable to autoclave before or after filtration. The invention also relates to the use of such a mixture for the control of harmful insects, mites and / or snails on green plants, the use of the mixture as a mosquito repellent, and a method for preparing this insecticidal mixture.

There is a wide range of insecticides on the world market today ·. The known insecticides have a more or less selective effect. They have a varied chemical structure, but the most important types are phosphorus esters, carbamates, halogenated hydrocarbons, chrysanthemum acid esters. In addition to the chrysanthemum acid esters, there are also a number of other naturally occurring insecticides, such as rotenoids. In addition, insecticidal proteins from bacteria are known, for example bacillus thuringienses. A good overview of classical insecticides and acaricides can be found in R. Wegler, "Chemie der Pflanzenschutz- und SchadlingsbekMmpfungsmittel", Springer-Verlag 1970. The previously known and used insecticides have caused various problems. A common problem is toxicity and the acute toxicity can be particularly strong with phosphorus esters and certain carbamates. This is very variable with halogenated hydrocarbons. Chrysanthemum acid esters are generally relatively low in toxicity, but synthetic derivatives thereof can also exhibit very high toxicity.

With certain classic insecticides, such as Temik, 8304047 w - 2 - there have been persistence problems causing residue problems.

The use of halogenated hydrocarbons, in certain cases, for example in DDT, has caused problems due to the accumulation in higher organisms in the food chain, for example in birds. This negatively affected their physiological functions and there have been cases where the population has decreased because the birds are laying eggs with too thin a shell.

Another very widespread problem with regard to the use of classic insecticides is the long-term resistance after use. This applies to phosphorus esters as well as carbamates. Pyretrine composites also cause these kinds of problems.

Fertilizers containing nitrogen, phosphorus and potassium as well as insecticides and fungicides are described in German Patent Application No. 2 453 523. Herbicide fertilizers containing German are known from German Publication 1 051 874, and they may also contain insecticides and 20 contain fungicides.

The damage to crops in the world as a result of insecticides and mites is very great, and the market potential for active insecticides and acaricides that do not cause the above environmental problems is therefore very high.

Thus, the object of the present invention is to provide such an anti-insect remedy that will not present the above-mentioned problems.

In accordance with the present invention, this is accomplished by an insecticide mixture of the above-mentioned kind, characterized in that it consists of a mixture of surfactants together with one or more gel and / or film-forming substances. A particularly preferred substance is gelatin.

For direct use, the mixture will be present in an aqueous solution.

The gelatin content per liter of water is 0.25-10.25 grams.

The tenside mixture consists, for example, of dead-cycbenzene sulphonate, nonyl-hydroxy-ethoxy-benzene-polyoxyethylene-ethanol, dodecyl-hydroxy-ethoxy-sulphonate, dodecyl-carboxy-2,2-dihydroxy-diethylamide, ethanol, prthoxenol and 5-carbamide , but other tenside mixtures may also be used for the same purpose.

The mixture is sprayed onto the plants to be protected on all sides of the green plant parts until they are dripping wet.

10 It may be beneficial to repeat the treatment at one-week intervals.

The mechanism for the effect of this mixture is likely to lie in the fact that the respiratory and food absorbing channels become clogged by the mixture, thereby blocking essential physiological functions.

Above all, the mixture influences the steps in these channels, and thus, although not directly, the mixture is effective against eggs, but only after the organism has passed the egg stage. In addition, the mixture can interfere with the motive members 20 that act through adhesion, and thus cause the organisms to be destroyed. Therefore, repeated spraying may be necessary.

Due to the general mechanism of the effect as indicated above, the mixture is apparently effective against all kinds of insects and mites.

Also snails and worms can often cause considerable damage in vegetable gardens.

The mixture according to the invention has also been shown to be particularly effective against snails and worms.

After contact with the mixture they are the first to lose their mucus membrane and shortly afterwards their respiratory organs are blocked. After about fifteen minutes they are dead.

The mixture can also be added directly to water for spraying the plants. ·

A preferred composition of the mixture according to the invention is as follows: 8304047 - 4 - 1. Nutrients containing nitrogen, phosphorus and potassium in the form of salt mixtures (18-14-22) 100.0 2. Mixtures of surfactant as a protective agent 5 etc., and a carrier for the preparation: dodecyl benzene sulphonate 45.0 nonyl hydroxyethoxybenzene polyoxyethylene ethanol 25.0 dodecyl hydroxyethoxy sulphate 2.32 dodecyl carboxy-2.2 -dihydroxy-diethylamide 1.68 ethanol 1.0 orthoxenol 0.8 carbamide 0.2 lb 3. gelatin (Relatin) a powdered, active 15 agents - ranging from 0.25-60 grams / liter 10.0 4. water- the rest _ TOTAL g / 1 186.0

The mixture can be prepared with continuous stirring in the following manner: 1. A pressurized kettle is filled with water which is brought to a boil.

2. The gelatin is mixed with the boiling water and completely dissolved.

25 3. The nutrients are dissolved in water and added.

4. The tensides mixture is added and boiled to 100 ° C under pressure.

5. The solution is then cooled to 18 ° C.

In the following, the mixture is referred to as aldecid according to the invention. For example, a recommended use is the following: 8 3 0 4 0 4 7 - 5 - m * ........ v MIX ALDECID WITH SPRAY WATER AND SPRAY WELL Against plant louse

Dosage 30ml / l water

Against tetranychus urticae 5 Dosage: first time 30ml / l water after hatching after about 7-8 days 20ml / l water

Against trialeurodes vaporariorum:

Dosage: first time 30ml / l water after 7-8 days 20ml / l water development period of the larvae at 21 ° C - 25 days third time 10ml / l water

Against snails 15 Dosage: 30ml / l water

Against mosquitoes and wasps

Dosage: 20-30ml / l water

In general: nutrients through the leaves 1-2 ml / 1 water 20 for protection in greenhouses 5-10ml / l water

Biological experiments show a mortality of 99%

The preparations can be used at home, in greenhouses and outdoors. Spraying is preferably carried out on two consecutive days, and then at 6-7 day intervals. The purpose of such spraying is that it should have a prophylactic effect.

The mixture has a repellent effect against mosquitoes. Spraying will have to be carried out in order to make the sprayed plant parts dripping wet. For insects occurring in forests, such as insects of the Tomicus species and Ips typographus, the dose should be 40 to 60 ml / l.

After treatment, the dead insects and mites, 83ü4ö47 - 6 - as well as mite eggs and larvae of the foliage can be sprayed with water.

The following experiments demonstrate the efficiency of the mixture according to the invention:. *

The treatment can also be carried out by dipping potted plants in a water bath. Dipping should take place for about 30 seconds. It is preferable to use about 30ml Aldecid 5 per liter of water for this treatment.

After the Aldecid treatment described above, the treated plants are always undamaged and in good condition.

With the present invention, a non-toxic insecticide that is not harmful to the environment is provided for pest control.

It is especially important for plants used to feed humans and animals, because in these cases it is necessary to guard against residual toxic substances.

The idea of the invention is defined in the following claims.
