Abstract
Herbicidally active compositions comprising: A) at least one 7-pyrazolylbenzoxazole compound of the formula (I) in which the variables R1-R5 are as defined in the patent claims and/or at least one of its agriculaturally acceptable salts; and at least one further active compound selected from herbicidally active compounds and safeners.
Description

The present invention relates to herbicidally active compositions comprising 7-pyrazolylbenzoxazoles and at least one further active compound selected from herbicidally active compounds and safeners.


In crop protection products, it is desirable in principle to increase the specificity and the reliability of the action of active compounds. In particular, it is desirable for the crop protection product to control the harmful plants effectively and, at the same time, to be tolerated by the useful plants in question.


Various publications have described 7-pyrazolylbenzoxazoles as being highly effective herbicides. However, their compatibility with dicotyledonous crop plants such as cotton, oilseed rape and some graminaceous plants such as barley, millet, corn, rice, wheat and sugar cane is not always satisfactory, i.e. in addition to the harmful plants, the crop plants are also damaged to an extent which is not acceptable. It is possible to spare the useful plants by lowering the application rates; however, the extent of the control of harmful plants is naturally also reduced.


It is known that certain combinations of different herbicides with specific action result in an enhanced activity of a herbicide component by synergism. As a consequence, it is possible to reduce the application rates of herbicidally active compounds required for controlling the harmful plants. Furthermore, it is known that in some cases better crop plant compatibility can be achieved by joint application of specifically acting herbicides with organic active compounds, some of which are themselves herbicidally active. In these cases, the active compounds act as antidote or antagonist, and, owing to the fact that they can reduce or even prevent damage to the crop plants, they are also referred to as safeners.

in which the variables RA-RE and Z are as defined below:

    • RA is hydrogen, C1-C4-alkyl or C1-C4-haloalkyl;
    • RB is cyano, C1-C4-alkyl, C1-C4-haloalkyl, C1-C4-alkoxy, C1-C4-haloalkoxy, C1-C4-alkylthio, C1-C4-haloalkylthio, C1-C4-alkylsulfinyl, C1-C4-haloalkylsulfinyl, C1-C4-alkylsulfonyl, C1-C4-haloalkylsulfonyl;
    • RC is hydrogen, cyano, nitro, halogen, C1-C4-alkyl or C1-C4-haloalkyl;
    • RD is halogen or hydrogen;
    • RE is hydrogen, halogen, cyano, C1-C4-alkyl, C1-C4-haloalkyl, C1-C4-alkoxy or C1-C4-haloalkoxy, and
    • Z together with the phenyl ring to which it is attached forms a benzoxazole ring or a benzothiazole ring which is substituted by various substituents.


However, the herbicidal action of the compounds described therein is unsatisfactory. Furthermore, at higher dosages, their compatibility with useful plants is not always ensured.


It is an object of the present invention to provide herbicidal compositions having increased activity against unwanted harmful plants and at the same time better compatibility with useful plants.


We have found that this object is achieved, surprisingly, by compositions comprising A) at least one 7-pyrazolylbenzoxazole of the formula I

      the agriculturally acceptable salts of the active compounds B and C and the agriculturally acceptable derivatives of the active compounds B and C, provided they have a carboxyl group.


The invention relates in particular to compositions in the form of herbicidally active crop protection compositions comprising a herbicidally effective amount of at least one mixture of A with B and/or C, as defined above, and at least one liquid and/or solid carrier, if desired, one or more surfactants and, if desired, one or more further auxiliaries customary for crop protection compositions. The invention also relates to compositions in the form of a crop protection composition formulated as a 2-component composition comprising a first component which comprises the active compound A, a solid or liquid carrier and, if appropriate, one or more surfactants, and a second component which comprises at least one further active compound selected from the herbicides B and the safeners C, a solid or liquid carrier and, if appropriate, one or more surfactants, where both components may additionally also comprise further auxiliaries customary for crop protection compositions.


Compositions according to the invention which comprise both at least one 7-pyrazolylbenzoxazole of the formula I and at least one herbicide-B surprisingly have better herbicidal activity, i.e. better action against harmful plants, than would have been expected based on the herbicidal action observed for the individual compounds. Compositions comprising a 7-pyrazolylbenzoxazole I, a herbicide B and one of the compounds mentioned under C likewise have better herbicidal action against harmful plants than would have been expected based on the herbicidal activity of the individual compounds. The herbicidal action to be expected, based on the individual compounds, for the mixtures can be calculated using Colby's formula (see below). If the observed activity exceeds the expected additive activity of the individual compounds, this is referred to as synergism.


Compositions according to the invention comprising both at least one 7-pyrazolylbenzoxazole of the formula I and at least one of the compounds listed under C show, with comparable herbicidal action, better compatibility with useful plants than a composition comprising the 7-pyrazolylbenzoxazole I on its own. This also applies, in a similar manner, to compositions comprising a 7-pyrazolylbenzoxazole I, a herbicide B and one of the compounds mentioned under C, compared to compositions comprising only a 7-pyrazolylbenzoxazole I and a herbicide B.


The invention furthermore relates to a method for controlling undesirable vegetation, in particular in crops of cereals, corn, soybeans, rice, oilseed rape, cotton, potatoes, groundnuts or in perennial crops, and also in crops which, by genetic engineering or by breeding, are resistant to one or more herbicides or to attack by insects. The invention also relates to a method for the desiccation or defoliation of plants. In the latter methods it is immaterial whether the herbicidally active compounds of components A) and B) and/or C) are formulated and applied jointly or separately, and, in the case of separate application, in which order the application takes place.

In the ready-to-use preparations, i.e. in the compositions according to the invention in the form of crop protection products, the components A and B and/or C, in suspended, emulsified or dissolved form, can be present formulated jointly or separately. The use forms depend entirely on the intended use.


The compositions according to the invention can be applied, for example, in the form of directly sprayable aqueous solutions, powders, suspensions, also highly-concentrated aqueous, oily or other suspensions or dispersions, emulsions, oil dispersions, pastes, dusts, materials for spreading or granules, by means of spraying, atomizing, dusting, broadcasting or watering. The use forms depend on the intended use; in any case, they should ensure the finest possible distribution of the active compounds.


Depending on the form in which the ready-to-use preparations are present in the compositions according to the invention, they comprise one or more liquid or solid carriers, if appropriate surfactants and if appropriate further auxiliaries which are customary for formulating crop protection products. The person skilled in the art is sufficiently familiar with the recipes for such formulations.


The ready-to-use preparations comprise the components A and B and/or C and auxiliaries which are customary for formulating crop protection products, which auxiliaries may also comprise a liquid carrier.


Suitable inert auxiliaries with carrier function are essentially:


mineral oil fractions of medium to high boiling point, such as kerosine and diesel oil, furthermore coal tar oils and oils of vegetable or animal origin, aliphatic, cyclic and aromatic hydrocarbons, e.g. paraffins, tetrahydronaphthalene, alkylated naphthalenes and their derivatives, alkylated benzenes and their derivatives, alcohols such as methanol, ethanol, propanol, butanol and cyclohexanol, ketones such as cyclohexanone, strongly polar solvents, e.g. amines such as N-methylpyrrolidone, and water.


Aqueous use forms can be prepared from emulsion concentrates, suspensions, pastes, wettable powders or water-dispersible granules by adding water. To prepare emulsions, pastes or oil dispersions, the active compounds A) to C), as such or dissolved in an oil or solvent, can be homogenized in water by means of wetting agent, tackifier, dispersant or emulsifier. Alternatively, it is also possible to prepare concentrates consisting of active substance, wetting agent, tackifier, dispersant or emulsifier and, if desired, solvent or oil, and these concentrates are suitable for dilution with water.


Suitable surfactants are the alkali metal salts, alkaline earth metal salts and ammonium salts of aromatic sulfonic acids, e.g. ligno-, phenol-, naphthalene- and dibutylnaphthalenesulfonic acid, and of fatty acids, of alkyl- and alkylarylsulfonates, of alkyl sulfates, lauryl ether sulfates and fatty alcohol sulfates, and salts of sulfated hexa-, hepta- and octadecanols and of fatty alcohol glycol ethers, condensates of sulfonated naphthalene and its derivatives with formaldehyde, condensates of naphthalene or of the naphthalenesulfonic acids with phenol and formaldehyde, polyoxyethylene octylphenol ether, ethoxylated isooctyl-, octyl- or nonylphenol, alkylphenyl polyglycol ether, tributylphenyl polyglycol ether, alkylaryl polyether alcohols, isotridecyl alcohol, fatty alcohol/ethylene oxide condensates, ethoxylated castor oil, polyoxyethylene alkyl ether or polyoxypropylene alkyl ether, lauryl alcohol polyglycol ether acetate, sorbitol esters, lignosulfite waste liquors or methylcellulose.


Powders, materials for spreading and dusts can be prepared by mixing or concomitantly grinding the active substances with a solid carrier.


Granules, e.g. coated granules, impregnated granules and homogeneous granules, can be prepared by binding the active compounds to solid carriers. Solid carriers are mineral earths such as silicas, silica gels, silicates, talc, kaolin, limestone, lime, chalk, bole, loess, clay, dolomite, diatomaceous earth, calcium sulfate, magnesium sulfate, magnesium oxide, ground synthetic materials, fertilizers such as ammonium sulfate, ammonium phosphate, ammonium nitrate, ureas, and products of vegetable origin such as cereal meal, tree bark meal, wood meal and nutshell meal, cellulose powders, or other solid carriers.


The concentrations of the active compounds in the ready-to-use preparations can be varied within wide ranges. In general, the formulations comprise approximately from 0.001 to 98% by weight, preferably 0.01 to 95% by weight, of active compounds. The active compounds are employed in a purity of from 90% to 100%, preferably 95% to 100% (according to NMR spectrum).


The compositions according to the invention can, for example, be formulated as follows:

  • I 20 parts by weight of the active compound or active compound mixture in question are dissolved in a mixture composed of 80 parts by weight of alkylated benzene, 10 parts by weight of the adduct of 8 to 10 mol of ethylene oxide to 1 mol of oleic acid N-monoethanolamide, 5 parts by weight of calcium dodecylbenzenesulfonate and 5 parts by weight of the adduct of 40 mol of ethylene oxide to 1 mol of castor oil. Pouring the solution into 100 000 parts by weight of water and finely distributing it therein gives an aqueous dispersion which comprises 0.02% by weight of the active compound.
  • II 20 parts by weight of the active compound or active compound mixture in question are dissolved in a mixture composed of 40 parts by weight of cyclohexanone, 30 parts by weight of isobutanol, 20 parts by weight of the adduct of 7 mol of ethylene oxide to 1 mol of isooctylphenol and 10 parts by weight of the adduct of 40 mol of ethylene oxide to 1 mol of castor oil. Pouring the solution into 100 000 parts by weight of water and finely distributing it therein gives an aqueous dispersion which comprises 0.02% by weight of the active compound.
  • III 20 parts by weight of the active compound or active compound mixture in question are dissolved in a mixture composed of 25 parts by weight of cyclohexanone, 65 parts by weight of a mineral oil fraction of boiling point 210 to 280° C. and 10 parts by weight of the adduct of 40 mol of ethylene oxide to 1 mol of castor oil. Pouring the solution into 100 000 parts by weight of water and finely distributing it therein gives an aqueous dispersion which comprises 0.02% by weight of the active compound.
  • IV 20 parts by weight of the active compound or active compound mixture in question are mixed thoroughly with 3 parts by weight of sodium diisobutylnaphthalenesulfonate, 17 parts by weight of the sodium salt of a lignosulfonic acid from a sulfite waste liquor and 60 parts by weight of pulverulent silica gel, and the mixture is ground in a hammer mill. Finely distributing the mixture in 20 000 parts by weight of water gives a spray mixture which comprises 0.1% by weight of the active compound.
  • V 3 parts by weight of the active compound or active compound mixture in question are mixed with 97 parts by weight of finely divided kaolin. This gives a dust which comprises 3% by weight of the active compound.
  • VI 20 parts by weight of the active compound or active compound mixture in question are mixed intimately with 2 parts by weight of calcium dodecylbenzenesulfonate, 8 parts by weight of fatty alcohol polyglycol ether, 2 parts by weight of the sodium salt of a phenol-urea-formaldehyde condensate and 68 parts by weight of a paraffinic mineral oil. This gives a stable oily dispersion.
  • VII 1 part by weight of the active compound or active compound mixture in question is dissolved in a mixture composed of 70 parts by weight of cyclohexanone, 20 parts by weight of ethoxylated isooctylphenol and 10 parts by weight of ethoxylated castor oil. This gives a stable emulsion concentrate.
  • VIII 1 part by weight of the active compound or active compound mixture in question is dissolved in a mixture composed of 80 parts by weight of cyclohexanone and 20 parts by weight of Wettol® EM 31 (nonionic emulsifier based on ethoxylated castor oil). This gives a stable emulsion concentrate.


The components A and B and/or C can be formulated jointly or separately.


The components A and B and/or C can be applied jointly or separately, simultaneously or successively, before, during or after emergence of the plants.


If the active compounds A and B and/or C are less well tolerated by certain crop plants, it is possible to use application methods in which the herbicidal compositions are sprayed with the aid of sprayers in such a way that the leaves of the sensitive crop plants are as far as possible unaffected, whereas the active compounds reach the leaves of the undesirable plants growing underneath or the uncovered soil surface (post-directed, lay-by).


The required application rate of the pure active compound composition, i.e. of A and B and/or C without formulation auxiliary, depends on the composition of the plant stem, on the development stage of the plants, on the climatic conditions of the location where the composition is used and on the application method. In general, the application rate of A and B and/or C is from 0.001 to 3 kg/ha, preferably from 0.005 to 2 kg/ha and in particular from 0.01 to 1 kg/ha of active substance (a.s.).


The required application rates of 7-pyrazolylbenzoxazoles are generally in the range from 0.1 g/ha to 1 kg/ha and preferably in the range from 1 g/ha to 500 g/ha or from 5 g/ha to 500 g/ha of a.s.


The compositions are applied to the plants mainly by foliar spraying. Application can be carried out by customary spraying techniques using, for example, water as carrier and spray liquor rates of from about 100 to 1000 l/ha (for example from 300 to 400l/ha). Application of the herbicidal compositions by the low-volume and the ultra-low-volume method is possible, as is their application in the form of micro granules.


The compositions according to the present invention are suitable for controlling common harmful plants in useful plants, in particular in crops such as wheat, barley, oats, corn, soybean, sorghum, rice, oilseed rape, cotton, potatoes, dry beans, groundnuts or in perennial crops. In another embodiment of the invention, they are useful for controlling the whole vegetation, i.e. they act as a total weedkiller. Futhermore, in another emodiment of the present invention, the compositions are useful for controlling undesirable vegetation in forestry.


Moreover, the compositions according to the present invention are also suitable for the desiccation and/or defoliation of plants.


As desiccants, they are suitable, in particular, for desiccating the above-ground parts of crop plants such as potatoes, oilseed rape, sunflowers and soya beans. This allows completely mechanical harvesting of these important crop plants.


Also of economic interest is

    • the coordinated dehiscence of fruits or the reduction of their adherence to the plant, for example in citrus fruit, olives or other kinds and species of pernicious fruit, stone fruit and nuts, since this facilitates harvesting of these fruits, and also the controlled defoliation of useful plants, in particular cotton. The dehiscence which is promoted by the application of compositions according to the invention is due to the formation of abscission tissue between the fruit or leaf and shoot part of the plants. The defoliation of cotton is of very particular economic interest since it facilitates harvesting. Simultaneously, the shortening of the window within which the individual plants mature leads to increased quality of the harvested fiber material.


Moreover, it may be useful to apply the compositions according to the invention jointly as a mixture with other crop protection products, for example with pesticides or agents for controlling phytopathogenic fungi or bacteria. Also of interest is the miscibility with mineral salt solutions which are employed for treating nutritional and trace element deficiencies. Non-phytotoxic oils and oil concentrates may also be added.


The compositions according to the invention can also be used in crop plants which are resistant to one or more herbicides owing to genetic engineering or breeding or which are resistant to attack by insects owing to genetic engineering or breeding. Suitable are for example crop plants which are resistant to herbicidal EPSP synthase inhibitors, such as, for example, glyphosate, to herbicidal glutamine synthase inhibitors, such as, for example, glufosinate, to herbicidal protoporphyrinogen-IX oxidase inhibitors, such as, for example, butafenacil, or to herbicidal ALS inhibitors, such as, for example, imazamethabenz, imazamox, imazapic, imazapyr, imazaquin, imazethapyr, or crop plants which, owing to introduction of the gene for Bt toxin by genetic modification, are resistant to attack by certain insects.


Surprisingly, the compositions according to the invention which comprise at least one 7-pyrazolylbenzoxazole of the formula I and at least one herbicide B have better herbicidal activity against harmful plants than would have been expected by the herbicidal activity of the individual compounds. In other words, the joint application of 7-pyrazolylbenzoxazole I and herbicide B results in an enhanced activity against harmful plants in the sense of a synergy effect (synergism). For this reason, the mixtures can, based on the individual components, be used at lower application rates to achieve a herbicidal effect comparable to the individual components.


Surprisingly, the compositions according to the invention which, in addition to the 7-pyrazolylbenzoxazole I and, if appropriate, the herbicide B, comprise an active compound from group C are better tolerated by useful plants than the respective 7-pyrazolylbenzoxazole I or the respective mixture of 7-pyrazolylbenzoxazole+herbicide B without active compound of group C.







USE EXAMPLES

The effect of the herbicidal mixtures according to the invention of components A and B and, if appropriate, C on the growth of undesirable plants compared to the herbicidally active compounds alone was demonstrated by the following greenhouse experiments (Examples 1 to 33):


For the post-emergence treatment, the test plants were first grown to a height of 3 to 20 cm, depending on the plant habit, and only then treated. Here, the herbicidal compositions were suspended or emulsified in water as distribution medium and sprayed using finely distributing nozzles.


For the pre-emergence treatment, the test plants were sown is pots 1-2 days later, i.e. prior to germination, the pots were sprayed with the finely distributed herbicidal compositions, which had been suspended in water.


The respective components A and B and/or C were formulated as 10% by weight strength emulsion concentrate and introduced to the spray liquor with the amount of solvent system used for applying the active compound. In the examples, the solvent used was water.


The test period extended over 21 days. During this time, the plants were tended, and their response to the treatments with active compound was evaluated.


The evaluation for the damage caused by the chemical compositions was carried out using a scale from 0 to 100%, compared to the untreated control plants. Here, 0 means no damage and 100 means complete destruction of the plants.


In the examples below, the value E which is to be expected if the activity of the individual active compounds is just additive was calculated using the method of S. R. Colby (1967) “Calculating synergistic and antagonistic responses of herbicide combinations”, Weeds 15, p. 22 ff.

E=X+Y—(X·Y/100)

where

    • X=effect in percent using active compound A at an application rate a;
    • Y=effect in percent using active compound B at an application rate b;
    • E=expected effect (in %) of A+B at application rates a+b.


If the value calculated in this manner is higher than the value E calculated according to Colby, a synergistic effect is present.


The plants used in the greenhouse experiments were of the following species:

The results of these tests are given in the tables of Examples 1 to 32 below and demonstrate the synergistic effect of mixtures comprising at least one 7-pyrazolylbenzoxazole I and at least one herbicide B. Example 33 demonstrates the effect of a mixture which comprises at least one 7-pyrazolylbenzoxazole I and at least one safener C.

Safener Action

As in the example above, test plants were grown, treated with the mixture according to the invention by the Pre-emergence method and, after a test period of 21 days, evaluated using a scale from 0 to 100% damage. The test plants used were crop plants.


A safener action is present if the damage to the crop plant caused by using a mixture according to the invention which comprises a safener C) is less than the damage caused when active compound A or active compounds A and B are used without safener.
