Synergistic compositions for inhibiting plant growth

The present invention relates to new plant growth-regulating combinations of certain azoles or pyrimidine butanol derivatives on the one hand and certain known phosphonic acid derivatives or 1-aminocyclopropane-1-carboxylic acid derivatives on the other hand.
It has already been disclosed that numerous triazole derivatives have plant growth-regulating properties (see DE-A (German Published Specification Nos.) 2,407,143, 2,737,489, 2,906,061, 2,645,617, 2,838,847 and JP-A (Japanese Published Specification) 53,130,661). However, the activity of the substances, especially when small quantities are used, is not always satisfactory.
Furthermore, it is already known that certain pyrimidine butanol derivatives can be used for regulating plant growth (see U.S. application Ser. No. 200,170 filed Oct. 24, 1980, now pending. In many cases, however, the activity of these substances also leaves something to be desired.
It is further known that phosphonic acid derivatives capable of ethylene cleavage affect plant growth (see DE-A (German Published Specification) 2,053,967). However, the activity of these substances is also not always adequate in practice.
Finally, it has already been reported that certain 1-amino-cyclopropane-1-carboxylic acid derivatives have plant growth-regulating properties (see U.S. application Ser. No. 192,744 filed Oct. 1, 1980, now pending. However, the results achieved with these substances are also not always completely satisfactory.

Surprisingly, the plant-growth inhibiting action of the active compound combinations according to the invention is substantially higher than the sum of the actions of the individual active compounds. Thus, a real synergistic effect, which cannot be foreseen, is present, and not only an extension of the action. The active compound combinations thus represent a valuable enrichment of the art.
The formulae (I), (II), (III), (IV) and (V) give general definitions of the azoles contained in the active compound combinations according to the invention.
Preferred azoles of formula (I) are those in which,
R.sup.1 represents a phenyl radical which is optionally monosubstituted, disubstituted or trisubstituted, the substituents being identical or different and being selected from fluorine, chlorine, bromine, phenyl, phenoxy, nitro alkyl having 1 to 4 carbon atoms, alkoxy having 1 to 4 carbon atoms, cycloalkyl having 3 to 7 carbon atoms, halogenoalkyl having 1 to 4 carbon atoms and 1 to 5 halogen atoms (particularly fluorine, chlorine and bromine atoms) and by cyano,
R.sup.2 represents a straight-chain or branched alkyl radical having 1 to 6 carbon atoms, or a halogenoalkyl radical having 1 to 6 carbon atoms and 1 to 5 halogen atoms (fluorine, chlorine and bromine being preferred),
X represents oxygen or methylene, and
Y represents carbonyl or a group --CH(OH).

Further particularly preferred azoles of the formula (II) are mentioned in the Preparative Examples.
The azoles of the formula (II) are already known (see U.S. application Ser. No. 152,949 filed May 23, 1980, now pending and DE-A (German Published Specification) 2,645,617).

Further particularly preferred azoles of the formula (III) are mentioned in the preparative examples hereinbelow.
Some of the azoles of the formula (III) are known (see DE-A (German Published Specification Nos.) 2,645,617, 2,838,847, JP-A (Japanese Published Specification) 53,130,661 and U.S. application Ser. No. 144,110, filed Apr. 28, 1980, now pending.
The azoles of the formula (III) can be present in two geometric isomer forms, according to the arrangement of the groups which are bonded to the double bond. If Y.sup.1 represents the group --CH(OH)--, an asymmetric carbon atom is present, so that the compounds of the formula (III) can also be present in this case in two optical isomer forms. The present invention relates to compositions comprising the individual isomers as well as compositions comprising the isomer mixtures.
Those azoles of the formula (III) in which R.sup.9 represents an optionally substituted aryl radical, R.sup.10 represents a tert.-butyl radical which is monosubstituted or disubstituted by halogen, and Y.sup.1 represents a carbonyl group or a group --CH(OH)--, are hitherto unknown. However, they can be prepared in a simple manner by reacting a triazolylmethyl-tert.-butyl ketone of the general formula ##STR352## in which
X.sup.3 and Y.sup.3 have the meanings given above, with an aldehyde of the general formula
R.sup.9 --CH.dbd.O (XI)
in which
R.sup.9 has the meaning given above, in the presence of an inert organic solvent and in the presence of a catalyst (such as a mixture of piperidine and glacial acetic acid) at a temperature between 20.degree. C. and 160.degree. C., and, if appropriate, reducing the azole of the general formula ##STR353## formed thereby, in which,
R.sup.9, X.sup.3 and Y.sup.3 have the meanings given above, according to known methods, in the presence of an inert diluent at a temperature between 0.degree. C. and 30.degree. C. Complex hydrides (such as sodium borohydride and lithium alanate) and also aluminum isopropylate or hydrogen in the presence of a catalyst are examples of suitable reducing agents.
Preferred azoles of formula (IV) are those in which,
R.sup.11 and R.sup.12 are identical or different and represent a cycloalkyl radical which is optionally substituted by methyl and which has 5 or 6 carbon atoms, a straight-chain or branched alkyl radical having 1 to 4 carbon atoms, a halogenoalkyl radical having 1 to 4 carbon atoms and 1 to 5 halogen atoms (such as fluorine or chlorine) or a phenyl radical which is optionally substituted by substituent(s) selected from fluorine, chlorine, bromine, alkyl having 1 to 4 carbon atoms, alkoxy having 1 to 4 carbon atoms, phenyl and nitro.
The azoles of the formula (IV) are known (see EP-A (European Published Patent Application) 0,005,600).
Preferred azoles of formula (V), are those in which,
R.sup.13 represents a straight-chain or branched alkyl radical having 1 to 4 carbon atoms, a cycloalkyl radical which has 3 to 7 carbon atoms and which is optionally substituted by alkyl having 1 or 2 carbon atoms, or a phenyl radical which is optionally monosubstituted or polysubstituted by identical or different substituents, preferred suitable substituents being selected from halogen, alkyl having 1 to 4 carbon atoms and halogenoalkyl having 1 to 2 carbon atoms and 1 to 5 identical or different halogen atoms (such as, in particular, fluorine and chlorine atoms),

X.sup.2, Y.sup.2 and m have the meanings given above.
Particularly preferred azoles of formula (VI) are those in which
R.sup.13 represents a tert.-butyl, isopropyl or methyl radical, a cyclopropyl, cyclopentyl or cyclohexyl radical, which is optionally substituted by methyl in each case, or a phenyl radical which is optionally monosubstituted or disubstituted, the substituents being identical or different and being selected from fluorine, chlorine, methyl and trifluoromethyl;
Z represents a fluorine, chlorine or bromine atom, a methyl, tert.-butyl, cyclohexyl, methoxy, methylthio, trifluoromethyl, trifluoromethoxy or trifluoromethylthio radical or a phenyl, phenoxy, benzyl or benzyloxy radical which is in each case optionally monosubstituted or disubstituted, the substituents being identical or different and being selected from fluorine, chlorine and methyl, and

If the active compounds are present in the active compound combinations according to the invention in certain proportions, the synergistic effect is particularly clearly exhibited. However, the proportions by weight of the active compounds in the active compound combinations can vary within relatively wide ranges. In general, 0.05 to 5 parts by weight, preferably 0.1 to 4 parts by weight, of one of the active compounds listed under (2) are present for 1 part by weight of an active compound listed under (1).
The active compound combinations according to the invention exhibit a powerful plant-growth inhibiting activity, particularly in the case of monocotyledonous plants, such as, for example, cereals and grass.
Inhibiting the growth in length of cereals is important because lodging of the stems of the cereal is thereby largely avoided, even under unfavorable weather conditions. By using the active compound combinations according to the invention, it is also possible to apply a fertilizer containing greater quantities of nitrogenous fertilizers, without danger of the cereal lodging. Thus, by using the active compound combinations according to the invention in conjunction with the application of a larger quantity of fertilizer, greater yields can be achieved.
The synergistic effect of the active compound combinations according to the invention, which effect has been described, can also be advantageously utilized for inhibiting the growth of grass. It is thus possible, for example, to reduce the frequency of cutting the grass in ornamental gardens, parks and athletic fields or at borders.
Cereals are to be understood in the present case as meaning all customary cereal types. These preferably include oats, rye, barley, wheat and rice.
The active compound combinations can be converted to the customary formulations, such as solutions, emulsions, suspensions, powders and granules.
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.
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 materials such as sawdust, coconut shells, corn 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 total active ingredients, preferably from 0.5 to 90 percent by weight.
The active compound combinations according to the invention can be present in the formulations as a mixture with other known active compounds, such as fungicides, insecticides, acaricides and herbicides, and also as mixtures with fertilizers.
The active compound combinations can be used as such, in the form of their formulations or as the use forms prepared therefrom, such as ready-to-use solutions, emulsifiable concentrates, emulsions, suspensions, wettable powders, soluble powders and granules.
They are used in the customary manner, for example by watering, spraying, atomizing and scattering.
The active compound concentrations 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.
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 composition of the present invention.
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 composition of the present invention was applied.
It will be seen that the usual methods of providing a harvested crop may be improved by the present invention.
The good plant-inhibiting action of the active compound combinations according to the invention can be seen from the examples which follow. While the individual active compounds have weaknesses in growth-inhibiting action, the combinations show an action which goes beyond a simple additive action.
A synergistic effect exists with growth inhibitors whenever the growth-inhibiting action of the active compound combinations is greater than the sum of the actions of the individually applied active compounds.
The action to be expected for a given combination of two growth inhibitors can (see Colby, S. R., "Calculating synergistic and antagonistic responses of herbicide combinations", Weeds 15, pages 20-22, 1967) be calculated as follows:
if X=% growth inhibition by active compound A used in an amount of p kg/ha,
and Y=% growth inhibition by active compound B used in an amount of q kg/ha,
and E=the expected growth inhibition by the active compounds A and B used in amounts of p and q kg/ha,
then ##EQU1##
If the actual growth inhibition is greater than calculated, the action of the combination is superadditive, that is to say a synergistic effect exists.
The tables in Examples A and B show clearly that the found growth-inhibiting action of the active compound combinations according to the invention is greater than the calculated action, that is to say a synergistic effect exists.
The active compounds indicated below are employed in the examples which follow: ##STR491##
