7.Description:
(en)This application is a continuation of application Ser. No. 577,287, filed Feb. 6, 1984 now abandoned, which is a division of Ser. No. 294,603, filed Aug. 20, 1981 now U.S. Pat. No. 4,486,218, in turn a continuation of Ser. No. 112,891, filed Jan. 17, 1980, now abandoned.


This invention relates to certain 1-vinyltriazole compounds, to plant growth regulant compositions and fungicidal compositions containing them, and to methods for regulating plant growth and for combating fungi.
It is known that certain 2-haloethyl-trialkyl-ammonium halides have plant growth regulating properties (see U.S. Pat. No. 3,156,554). Thus, for example, an influencing of plant growth, in particular an inhibition of vegetative plant growth, can be achieved in important crop plants with the aid of 2-chloroethyl-trimethylammonium chloride. However, the activity of this substance is not always adequate, especially when small amounts are used.
It is also known that 2-chloroethylphosphonic acid has a plant growth regulating action (see DE-OS (German Published Specification) 1,667,968). However, the results achieved with this substance are likewise not always satisfactory.
Furthermore, it is known that acylated and carbamoylated derivatives of 3,3-dimethyl-1-phenoxy-1-triazolyl-butan-2-ols, which are substituted in the phenyl part, have a good fungicidal activity (see DE-OS (German Published Specification) 2,600,799). Certain 4,4-dimethyl-1-phenyl-2-triazolyl-pentan-3-ones, which are substituted in the phenyl part, for example, 1-(4-chlorophenyl)-4,4-dimethyl-2-(1,2,4-triazol-1-yl)-pentan-3-one, are likewise suitable for combating fungi (see DE-OS (German Published Specification) 2,734,426). However, the action of these azole derivatives is not always completely satisfactory, especially when small amounts and low concentrations are used.
The present invention now provides, as new compounds, the 1-vinyl-triazole derivatives of the formula ##STR3## in which R 1 represents optionally substituted alkyl, cycloalkyl or optionally substituted aryl,
R 2 represents alkyl and
R 3 represents alkyl, cycloalkyl, optionally substituted cycloalkenyl, alkenyl or optionally substituted aryl, or
R 2 and R 3 , together with the carbon atom to which they are bonded, represent optionally substituted cycloalkenyl or cycloalkyl,
X represents the group ##STR4## or alternatively may represent the keto group provided that R 1 represents optionally substituted alkyl or cycloalkyl,
R 4 represents hydrogen, alkyl, optionally substituted aralkyl, acyl or optionally substituted carbamoyl, and
R 5 represents hydrogen, alkyl or optionally substituted aralkyl,
and acid addition salts and metal salt complexes thereof.
It has been found that the 1-vinyltriazole derivatives of the formula (I) and acid addition salts and metal salt complexes thereof have powerful plant growth regulating properties and powerful fungicidal properties.
Preferably, in formula (I), R 1 represents straight-chain or branched alkyl with 1 to 4 carbon atoms [which optionally carries one or two substituents selected independently from, preferably, halogen, alkylcarbonyloxy with 1 to 4 carbon atoms in the alkyl part, alkylsulphonyloxy with 1 to 4 carbon atoms and phenylsulphonyloxy which is itself optionally substituted by halogen or by alkyl with 1 to 4 carbon atoms], cycloalkyl with 5 to 7 carbon atoms or aryl with 6 to 10 carbon atoms (such as phenyl or naphthyl) [which aryl optionally carries one or more substituents selected independently from, preferably, halogen, alkyl with 1 to 4 carbon atoms, phenyl, phenoxy, halophenyl and halophenoxy], R 2 represents straight-chain or branched alkyl with 1 to 4 carbon atoms, and R 3 represents straight-chain or branched alkyl with 1 to 4 carbon atoms, cycloalkyl with 5 to 7 carbon atoms, cycloalkenyl with 5 to 7 carbon atoms [which is optionally substituted by alkyl with 1 to 4 carbon atoms], alkenyl with 2 to 4 carbon atoms or aryl with 6 to 10 carbon atoms (such as phenyl or naphthyl) [which is optionally substituted by, preferably, halogen or alkyl with 1 to 4 carbon atoms], or R 2 and R 3 , together with the carbon atom to which they are bonded, represent cycloalkenyl with 5 to 7 carbon atoms [which is optionally substituted by alkyl with 1 to 4 carbon atoms] or cycloalkyl with 3 to 7 carbon atoms, X represents the group --C(OR 4 )R 5 --, or may represent the keto group provided R 1 represents optionally substituted alkyl or cycloalkyl, R 4 represents hydrogen, straight-chain or branched alkyl with 1 to 4 carbon atoms, aralkyl with 1 to 2 carbon atoms in the alkyl part and 6 to 10 carbon atoms in the aryl part (such as benzyl or naphthylmethyl) [which optionally carries one or more substituents selected independently from, preferably, halogen, alkyl with 1 to 4 carbon atoms, haloalkyl with up to 2 carbon atoms and up to 3 identical or different halogen atoms (preferred halogen atoms being fluorine and chlorine) and phenyl and phenoxy, the last two being themselves optionally substituted by halogen], the acyl radical --CO--R 10 or the carbamoyl radical --CO--NR 11 R 12 , R 5 represents hydrogen, alkyl with 1 to 4 carbon atoms or aralkyl with 1 to 2 carbon atoms in the alkyl part and 6 to 10 carbon atoms in the aryl part (such as benzyl) [which is optionally substituted by halogen or alkyl with 1 to 4 carbon atoms], R 10 represents straight-chain or branched alkyl with 1 to 4 carbon atoms, haloalkyl with 1 to 2 carbon atoms and 1 to 5 identical or different halogen atoms (preferably fluorine and chlorine atoms) or phenyl or benzyl [either of which is optionally substituted by, preferably, halogen or alkyl with 1 to 4 carbon atoms], R 11 represents hydrogen or alkyl with 1 to 4 carbon atoms, and R 12 represents alkyl with 1 to 8 carbon atoms, haloalkyl with up to 4 carbon atoms and up to 5 identical or different halogen atoms (especially fluorine or chlorine atoms), aryl with 6 to 10 carbon atoms (such as phenyl or naphthyl) [which optionally carries one or more substituents selected independently from, preferably, halogen, alkyl with 1 to 4 carbon atoms and haloalkyl with up to 2 carbon atoms and up to 5 identical or different halogen atoms (especially fluorine and chlorine atoms)] or haloalkylmercapto with 1 to 2 carbon atoms and up to 5 halogen atoms (especially fluorine and chlorine atoms).
The compounds of the formula (I) can exist in two geometric isomer forms, depending on the arrangement of the groups which are bonded to the double bond. If X represents the group --C(OR 4 )R 5 --, an asymmetric carbon atom is present, so that in this case the compounds of the formula (I) are also obtained in two optical isomer forms. The formula (I) therefore embraces both the individual isomers and the isomer mixtures.
The invention also provides a process for the preparation of a 1-vinyltriazole derivative of the formula (I), or an acid addition salt or metal salt complex thereof, in which
(a) a triazole-ketone of the general formula ##STR5## in which R 1 has the meaning indicated above, is reacted with an aldehyde of the general formula ##STR6## in which R 2 and R 3 have the meanings indicated above, in the presence of a solvent and in the presence of a catalyst, and from the isomers which form, as a result of splitting off of water, the desired isomeric product of the general formula ##STR7## in which R 1 , R 2 and R 3 have the meanings indicated above, is isolated by customary methods, or
(b) a compound, obtainable by process variant (a), of the general formula ##STR8## in which R 1 , R 2 and R 3 have the meanings indicated above is either

Surprisingly, the 1-vinyltriazoles according to the invention and acid addition salts and metal salt complexes thereof exhibiting a better plant growth regulating action than the known 2-chloroethyl-trimethylammonium chloride and 2-chloroethylphosphonic acid, which is likewise known, which are recognized as substances of the same type of action which have a good activity. Surprisingly, the compounds according to the invention also have a better fungicidal action than the acylated and carbamoylated derivatives of 3,3-dimethyl-1-phenoxy-1-triazolyl-butan-2-ols substituted in the phenyl part, which are known from the state of the art, and than 1-(4-chlorophenyl)-4,4-dimethyl-2-(1,2,4-triazol-1-yl)-pentan-3-one, which is likewise known, which are closely related compounds chemically and from the point of view of their action. The active compounds according to the invention thus represent an enrichment of the art.

The compounds according to the present invention engage in the metabolism of plants and can therefore be employed as growth regulators.
Experience to date of the mode of action of plant growth regulators has shown that an active compound can exert one or several different actions on plants. The actions of the compounds depend essentially on the point in time at which they are used, relative to the stage of development of the seed or of the plant, and on the amounts of active compound applied to the plants or their environment and the way in which the compounds are applied. In every case, growth regulators are intended positively to influence the crop plants in the desired manner.
Plant growth-regulating compounds can be employed, for example, to inhibit vegetative plant growth. Such inhibition of growth is inter alia of economic interest in the case of grasses since, by repressing the growth of grass, it is possible, for example, to reduce the frequency of cutting the grass in ornamental gardens, parks and sports grounds or at verges. The inhibition of growth of herbaceous and woody plants at verges and in the vicinity of overland pipelines or, quite generally, in areas in which heavy growth is undesired, is also of importance.
The use of growth regulators to inhibit the growth in length of cereals is also important, since by shortening the stem the danger of lodging of the plants before harvesting is reduced or completely eliminated. Furthermore, growth regulators can strengthen the stem of cereals, which can counteract lodging.
In the case of many crop plants, inhibition of the vegetative growth permits denser planting of the crop, so that a greater yield per area of ground can be achieved.
A further mechanism of increasing the yield by means of growth inhibitors is based on the fact that the nutrients benefit blossoming and fruit formation to a greater extent, while vegetative growth is restricted.
Promotion of vegetative growth can also frequently be achieved with growth regulators. This is of great utility if it is the vegetative parts of the plants which are harvested. Promoting the vegetative growth can, however, also simultaneously lead to a promotion of generative growth, so that, for example, more fruit, or larger fruit, is formed.
Increases in yield can in some cases also be achieved by affecting the plant metabolism, without noticeable changes in vegetative growth. Growth regulators can furthermore produce a change in the composition of the plants so as to bring about better quality of the harvested products. Thus it is possible, for example, to increase the content of sugar in sugar beet, sugar cane, pineapples and citrus fruit or to increase the protein content in soya or cereals.
Parthenocarpous fruit can be formed under the influence of growth regulators. Furthermore, the gender of the flowers can be influenced.
Using growth regulators it is also possible favorably to influence the production or the efflux of secondary plant materials. The stimulation of latex flow in rubber trees may be mentioned as an example.
During the growth of the plant, lateral branching can also be increased, by using growth regulators, through chemical breaking of the apical dominance. There is interest in this, for example, in the case of plant propagation by cuttings. However, it is also possible to inhibit the growth of side shoots, for example to prevent the formation of side shoots in tobacco plants after decapitation and thus to promote leaf growth.
The amount of leaf on plants can be controlled, under the influence of growth regulators, so that defoliation of the plants at a desired point in time is achieved. Such defoliation is of interest to facilitate mechanical harvesting, for example of grapes or cotton, or to lower the transpiration at a point in time at which the plant is to be transplanted.
Premature shedding of fruit can be prevented by the use of growth regulators. However, it is also possible to promote the shedding of fruit-for example in the case of table fruit-in the sense of a chemical thinning out, up to a certain degree. Growth regulators can also be used to reduce the force required to detach the fruit from crop plants at harvest time so as to permit mechanical harvesting of the plants or facilitate manual harvesting.
Using growth regulators it is furthermore possible to achieve an acceleration or retardation of ripening of the harvest product, before or after harvesting. This is of particular advantage since it is thereby possible to achieve optimum adaptation to market requirements. Furthermore, growth regulators can at times improve the coloration of fruit. In addition, concentrating the ripening within a certain period of time is also achievable with the aid of growth regulators. This provides the preconditions for being able to carry out complete mechanical or manual harvesting in only a single pass, for example in the case of tobacco, tomatoes or coffee.
Using growth regulators it is also possible to influence the latent period of seeds or buds of plants, that is to say the endogenic annual rhythm, so that the plants, such as, for example, pineapple or decorative plants in nurseries, germinate, shoot or blossom at a time at which they normally show no readiness to do so.
Using growth regulators it is also possible to achieve a delay in the shooting of buds or the germination of seeds, for example to avoid damage by late frosts in regions where frost is a hazard.
Growth regulators can also produce halophilism in crop plants. This provides the preconditions for being able to cultivate plants on soils containing salt.
Using growth regulators, it is also possible to induce frost resistance and drought resistance in plants.
The preferred time of application of the growth regulators depends on the climatic and vegetative circumstances.
The foregoing description should not be taken as implying that each of the compounds can exhibit all of the described effects on plants. The effect exhibited by a compound in any particular set of circumstances must be determined empirically.
The active compounds according to the invention also exhibit a powerful microbicidal action and can be employed in practice for combating undesired micro-organisms. The active compounds are suitable for use as plant protection agents.
Fungicidal agents in plant protection are employed for combating Plasmodiophoromycetes, Oomycetes, Chytridiomycetes, Zygomycetes, Ascomycetes, Basidiomycetes and Deuteromycetes.
The good toleration, by plants, of the active compounds, at the concentrations required for combating plant diseases, permits treament of above-ground parts of plants, of vegetative propagation stock and seeds, and of the soil.
As plant protection agents, the active compounds which can be used according to the invention can be employed with particularly good success for combating those fungi which cause powdery mildew diseases, especially for combating Erysiphe species, for example the powdery mildew of barley or cereal causative organism (Erysiphe graminis). It should be particularly emphasized that the active compounds according to the invention not only develop a protective action, but also have a systemic action. Thus, it is possible to protect plants against fungal attack when the active compound is fed to the above-ground parts of the plants via the soil and the root or via the seed.
The active compounds can be converted into the customary formulations, such as solutions, emulsions, powders, suspensions, powders, dusting agents, foams, pastes, soluble powders, granules, aerosols, suspension-emulsion concentrates, seed-treatment powders, natural and synthetic materials impregnated with active compound, very fine capsules in polymeric substances, coating compositions for use on seed, and formulations used with burning equipment, such as fumigating cartridges, fumigating cans and fumigating coils, as well as ULV cold mist and warm mist formulations.
These formulations may be produced in known manner, for example by mixing the active compounds with extenders, that is to say liquid or liquefied gaseous or solid diluents or carriers, optionally with the use of surface-active agents, that is to say emulsifying agents and/or dispersing agents and/or foam-forming agents. In the case of the use of water as an extender, organic solvents can, for example, also be used as auxiliary solvents.
As liquid diluents or carriers, especially solvents, there are suitable in the main, aromatic hydrocarbons, such as xylene, toluene or alkyl naphthalenes, chlorinated aromatic or chlorinated aliphatic hydrocarbons, such as chlorobenzenes, chloroethylenes or methylene chloride, aliphatic or alicyclic hydrocarbons, such as cyclohexane or paraffins, for example mineral oil fractions, alcohols, such as butanol or glycol as well as their ethers and esters, ketones, such as acetone, methyl ethyl ketone, methyl isobutyl ketone or cyclohexanone, or strongly polar solvents, such as dimethylformamide and dimethylsulphoxide, as well as water.
By liquefied gaseous diluents or carriers are meant liquids which would be gaseous at normal temperature and under normal pressure, for example aerosol propellants, such as halogenated hydrocarbons as well as butane, propane, nitrogen and carbon dioxide.
As solid carriers there may be used ground natural minerals, such as kaolins, clays, talc, chalk, quartz, attapulgite, montmorillonite or diatomaceous earth, and ground synthetic minerals, such as highly-dispersed silicic acid, alumina and silicates. As solid carriers for granules there may be used crushed and fractionated natural rocks such as calcite, marble, pumice, sepiolite and dolomite, as well as synthetic granules of inorganic and organic meals, and granules of organic material such as sawdust, coconut shells, maize cobs and tobacco stalks.
As emulsifying and/or foam-forming agents there may be used non-ionic and anionic emulsifiers, such as polyoxyethylene-fatty acid esters, polyoxyethylene-fatty alcohol ethers, for example alkylaryl polyglycol ethers, alkyl sulphonates, alkyl sulphates, aryl sulphonates as well as albumin hydrolysis products. Dispersing agents include, for example, lignin sulphite waste liquors and methylcellulose.
Adhesives such as carboxymethylcellulose and natural and synthetic polymers in the form of powders, granules or latices, such as gum arabic, polyvinyl alcohol and polyvinyl acetate, can be used in the formulations.
It is possible to use colorants such as inorganic pigments, for example iron oxide, titanium oxide and Prussian Blue, and organic dyestuffs, such as alizarin dyestuffs, azo dyestuffs or metal phthalocyanine dyestuffs, and trace nutrients, such as salts of iron, manganese, boron, copper, cobalt, molybdenum and zinc.
The formulations in general contain from 0.1 to 95 percent by weight of active compound, preferably from 0.5 to 90 percent by weight.
The active compounds according to the invention can be present in the formulations, or in the various use forms, as a mixture with other active compounds, such as fungicides, bactericides, insecticides, acaricides, nematicides, herbicides, bird repellants, growth factors, plant nutrients and agents for improving soil structure, as well as other plant growth regulators.
The active compounds can be used as such or in the form of their formulations or the use forms prepared therefrom by further dilution, such as ready-to-use solutions, emulsions, suspensions, powders, pastes and granules. They are used in the customary manner, for example by watering, immersion, spraying, atomizing, misting, vaporizing, injecting, forming a slurry, brushing on, dusting, scattering, dry dressing, moist dressing, wet dressing, slurry dressing or encrusting. Furthermore, it is possible to apply the active compounds in accordance with the ultra-low volume process or to inject the active compound preparation or the active compound itself into the soil. It is also possible to treat the seeds of plants.
When the compounds according to the invention are used as plant growth regulators, the amounts used can be varied within a substantial range. In general, 0.01 to 50 kg, preferably 0.05 to 10 kg, of the active compound are employed per hectare of soil surface.
When the substances according to the invention are used as fungicides, the amount used can also be varied within a substantial range, depending on the nature of the application. Thus, especially in the treatment of parts of plants, the active compound concentrations in the use forms are in general between 1 and 0.001% by weight, especially between 0.5 and 0.001%. In the treatment of seed, amounts of active compound of 0.001 to 50 g, especially 0.01 to 10 g, are generally required per kilogram of seed. For the treatment of soil, active compound concentrations of 0.00001 to 0.1% by weight, especially 0.0001 to 0.02%, are generally required at the place of action.
The present invention also provides plant-growth regulating or fungicidal compositions containing as active ingredient a compound of the present invention in admixture with a solid or liquefied gaseous diluent or carrier or in admixture with a liquid diluent or carrier containing a surface-active agent.
The present invention also provides a method of combating fungi which comprises applying to the fungi, or to a habitat thereof, a compound of the present invention alone or in the form of a composition containing as active ingredient a compound of the present invention in admixture with a diluent or carrier.
The present invention also provides a method of regulating the growth of plants which comprises applying to the plants, or to a habitat thereof, a compound of the present invention alone or in the form of a composition containing as active ingredient a compound of the present invention in admixture with a diluent or carrier.
The present invention further provides crops protected from damage by fungi by being grown in areas in which immediately prior to and/or during the time of the growing a compound of the present invention was applied alone or in admixture with a diluent or carrier.
The present invention further provides plants, the growth of which has been regulated by their being grown in areas in which immediately prior to and/or during the time of the growing a compound of the present invention was applied alone or in admixture with a diluent or carrier.
It will be seen that the usual methods of providing a harvested crop may be improved by the present invention.

To produce a suitable preparation of active compound, 0.25 part by weight of active compound was taken up in 25 parts by weight of dimethylformamide and 0.06 part by weight of alkylaryl polyglycol ether; 975 parts by weight of water were then added. The concentrate was diluted with water to the desired final concentration of the spray liquor.
To test for protective activity, single-leaved young barley plants of the Amsel variety were sprayed with the preparation of active compound until dew-moist. After drying, the barley plants were dusted with spores of Erysiphe graminis var. hordei.
After 6 days' dwell time of the plants at a temperature of 21-22 deg. C. and 80-90% atmospheric humidity the occurrence of mildew pustules on the plants was evaluated. The degree of infection was expressed as a percentage of the infection of the untreated control plants. 0% denoted no infection and 100% denoted the same degree of infection as in the case of the untreated control. The active compound was the more active, the lower was the degree of mildew infection.
In this test, for example, the following compounds exhibited a very good action, which was superior to that of the compounds (C), (D) and (E) known from the prior art: compounds (2), (3), (16), (4), (11) and (12).
EXAMPLE G
Powdery mildew of barley (Erysiphe graminis var. hordei) (fungal disease of cereal shoots)/systemic.
The active compound was used as a pulverulent seed treatment agent. This was prepared by extending the particular active compound with a mixture of equal parts by weight of talc and kieselguhr to give a finely pulverulent mixture of the desired concentration of active compound.
For the treatment of seed, barley seed was shaken with the extended active compound in a closed glass bottle. The seed was sown at the rate of 3×12 grains in flowerpots, 2 cm deep in a mixture of one part by volume of Fruhstorfer standard soil and one part by volume of quartz sand. The germination and emergence took place under favourable conditions in a greenhouse. 7 days after sowing, when the barley plants had developed their first leaf, they were dusted with fresh spores of Erysiphe graminis var. hordei and grown on at 21-22 deg. C. and 80-90% relative atmospheric humidity and 16 hours' exposure to light. The typical mildew pustules formed on the leaves over the course of 6 days.
The degree of infection was expressed as a percentage of the infection of the untreated control plants. Thus, 0% denoted no infection and 100% denoted the same degree of infection as in the case of the untreated control. The active compound was the more active, the lower was the degree of mildew infection.
In this test, for example, the following compounds exhibited a very good action which was superior to that of the compounds (F), (G) and (H) known from the prior art: compounds (2), (3), (4), (11) and (12).
EXAMPLE H
Mycelium growth test
Nutrient medium used:
20 parts by weight of agar-agar
200 parts by weight of potato decoction
5 parts by weight of malt
15 parts by weight of dextrose
5 parts by weight of peptone
2 parts by weight of disodium hydrogen phosphate
0.3 part by weight of calcium nitrate
Ratio of solvent mixture to nutrient medium:
2 parts by weight of solvent mixture
100 parts by weight of agar nutrient medium
Composition of the solvent mixture:
0.19 part by weight of acetone or dimethylformamide
0.01 part by weight of emulsifier (alkylaryl) polyglycol ether)
1.80 parts by weight of water
The amount of active compound required for the desired active compound concentration in the nutrient medium was mixed with the stated amount of solvent mixture. The concentrate was thoroughly mixed, in the stated proportion, with the liquid nutrient medium (which had been cooled to 42 deg. C.) and was then poured into Petri dishes of 9 cm diameter. Control plates to which the preparation had not been added were also set up.
When the nutrient medium had cooled and solidified, the plates were inoculated with the species of organisms stated hereinbelow and incubated at about 21 deg. C.
Evaluation was carried out after 4-10 days, dependent upon the speed of growth of the organisms. When evaluation was carried out the radial growth of the organism on the treated nutrient media was compared with the growth on the control nutrient medium. In the evaluation of the organism growth, the following characteristic values were used:
1 no growth
up to
3 very strong inhibition of growth
up to
5 medium inhibition of growth
up to
7 slight inhibition of growth
9 growth equal to that of untreated control.
As test organisms, the following fungi were employed:
In this test, for example, the following compounds exhibited a very good action which was superior to that of the compound (I) known from the prior art: compounds (2) and (3).
EXAMPLE I
Inhibition of growth of rice
Solvent: 30 parts by weight of dimethylformamide
Emulsifier: 1 part by weight of polyoxyethylene sorbitan monolaurate
To produce a suitable preparation of active compound, 1 part by weight of active compound was mixed with the stated amounts of solvent and emulsifier and the mixture was made up to the desired concentration with water.
Rice plants were grown in a green-house to the 2-leaf stage in 10×10×10 cm pots filled with earth. In this stage, the plants were sprayed with the preparations of active compound until dripping wet. After 10 days, the additional growth was measured on all plants and the inhibition of growth in percent of the additional growth of the control plants was calculated. 100% inhibition of growth meant that growth had stopped and 0% denoted a growth corresponding to that of the control plants.
In this test, active compound (2) exhibited a strong growth inhibiting activity.
EXAMPLE J
Inhibition of growth of water-rice (var. Nihonbare)
5 parts of active compound were mixed in a mixer with 2.5 parts of Newkalgen CP-50 + ), 30 parts of Bentonit and 62.5 parts of talum. Then 20 parts of water were added. The pasty material was pressed through holes of a diameter of 0.5 mm and then was dried. There was obtained a granulate having a corn size of a diameter of 0.5 mm and a length of 0.7 mm.
Ten days old rice plants were planted in containers having a size of 25×20×10 cm, in which containers water is dammed up above the soil. After 10 days, the preparation of active compound was applied to the water. After an additional period of 14 days, the height of the plants was measured ##STR267## R=Ethylene or propylene in a ratio of 9:1
In this test, the active compound (2) exhibited a very strong growth inhibiting activity.
