The invention relates to novel selective herbicidal active compound combinations which comprise substituted isoxazolincarboxamides or agrochemical acceptable salts thereof and benoxacor and which can be used with particularly good results for the selective control of weeds in various crops of useful plants. Substituted isoxazolincarboxamides are already known as effective herbicides from WO 2018/228985 and WO 2019/145245. However, the activity of these compounds and/or their compatibility with crop plants are not entirely satisfactory under all conditions.

Benoxacor (IUPAC: 2,2-dichloro-l-(3-methyl-2,3-dihydro-l,4-benzoxazin-4-yl)eth anone; CAS: 98730-04-2) is a safener known from EP 0149974. Surprisingly, it has now been found that certain substituted isoxazolincarboxamides, when used together with benoxacor described below, prevent damage to crop plants extremely well and can be used particularly advantageously as broad-spectrum combination preparations for the selective control of weeds (= undesirable plants) in crops of useful plants, such as, for example, in cereals and maize.

Table 1: Examples for compounds of the formula (la)

Surprisingly, it has now been found that the above-defined active compound combinations of substituted isoxazolincarboxamides of the general formula (I) and/or their salts and benoxacor, whilst being tolerated very well by crop plants, have particularly high herbicidal activity and can be used in various crops, in particular in cereal (especially wheat and barley) and maize, but also in soya beans, potatoes and rice, for the selective control of weeds (= undesirable plants).

Here, it has to be considered to be surprising that, from a large number of known safeners or antidotes which are capable of antagonizing the damaging effect of a herbicide on the crop plants, that it is benoxacor which neutralize the damaging effect of substituted isoxazolincarboxamides on the crop plants virtually completely without negatively affecting the herbicidal activity with respect to the weeds.

Emphasis is given here to the particularly advantageous effect of benoxacor, in particular in respect of sparing cereal plants, such as, for example, wheat, barley and rye, but also maize and rice, as crop plants.

The active compound combinations according to the invention can be used, for example, in connection with the following plants:

Dicotyledonous weeds of the genera: Sinapis, Lepidium, Galium, Stellaria, Matricaria, Anthemis, Galinsoga, Chenopodium, Urtica, Senecio, Amaranthus, Portulaca, Xanthium, Convolvulus, Ipomoea, Polygonum, Sesbania, Ambrosia, Cirsium, Carduus, Sonchus, Solanum, Rorippa, Rotala, Lindemia, Lamium, Veronica, Abutilon, Emex, Datura, Viola, Galeopsis, Papaver, Centaurea, Trifolium, Ranunculus, Taraxacum.

However, the use of the active compound combinations according to the invention is in no way restricted to these genera, but also extends in the same manner to other plants. According to the invention, crop plants are all plants and plant varieties including transgenic plants and plant varieties, where on transgenic plants and plant varieties it is also possible for synergistic effects to occur. The invention furthermore relates to a method of reducing crop damage by treating the seed of the crop with the safener before sowing. This can be done in addition to the use of herbicide/safener combinations and compositions comprising thereof, which are highly suitable to protect crops from herbicide damage in pre-and post-emergence treatments.

It was an object of the present invention to provide a method for further reducing crop damage using known combinations of herbicides and safener and compositions comprising thereof. Surprisingly, this object is achieved by the following methods/schemes of treatment:

Method A

Step 1 : Treatment of the seed with benoxacor

Step 2: Applying compound of formula (I) or compositions comprising thereof in a post-emergence treatment

Method B

Step 1 : Treatment of the seed with benoxacor

Step 2: Applying compound of formula (I) or compositions comprising thereof in a pre-emergence treatment

Preferred are the following methods:

Method A-a

Step 1 : Treatment of the seed with benoxacor

Step 2: Applying compound of formula (la) or compositions comprising thereof in a post-emergence treatment

Method B-a

Step 1 : Treatment of the seed with benoxacor

Step 2: Applying compound of formula (la) or compositions comprising thereof in a pre-emergence treatment

Seed: Seed of crop plants, such as, for example, various cereal species (such as wheat, triticale, barley, rye), com, maize.

Composition

Compositions within the context of the present invention comprise in addition to the herbicide/safener combinations according to the invention one or more further component(s) which include, but are not limited to the following: formulation auxiliaries, additives customary in crop protection, further agrochemically active compounds (e.g. fungicides and insecticides).

The active compounds or active compound combinations/compositions can be converted into the customary formulations, such as solutions, emulsions, wettable powders, suspensions, powders, dusting agents, pastes, soluble powders, granules, suspoemulsion concentrates, natural and synthetic materials impregnated with active compound, and very fine capsules in polymeric substances.

These formulations are produced in a known manner, for example by mixing the active compounds with extenders, that is liquid solvents and/or solid carriers, optionally with the use of surfactants, that is emulsifiers and/or dispersants and/or foam-formers.

If the extender used is water, it is also possible to use, for example, organic solvents as auxiliary solvents. Suitable liquid solvents are essentially: aromatics, such as xylene, toluene or alkylnaph- thalenes, chlorinated aromatics and chlorinated aliphatic hydrocarbons, such as chlorobenzenes, chloroethylenes or methylene chloride, aliphatic hydrocarbons, such as cyclohexane or paraffins, for example petroleum fractions, mineral and vegetable oils, alcohols, such as butanol or glycol, and also their ethers and esters, ketones, such as acetone, methyl ethyl ketone, methyl isobutyl ketone or cyclohexanone, strongly polar solvents, such as dimethylformamide and dimethyl sulphoxide, and also water.

Suitable solid carriers are: for example ammonium salts and ground natural minerals, such as kaolins, clays, talc, chalk, quartz, attapulgite, montmorillonite or diatomaceous earth, ground synthetic minerals, such as finely divided silica, alumina and silicates, suitable solid carriers for granules are: for example crushed and fractionated natural rocks such as calcite, marble, pumice, sepiolite and dolomite, and also synthetic granules of inorganic and organic meals, and granules of organic material such as sawdust, coconut shells, maize cobs and tobacco stalks; suitable emulsifiers and/or foam-formers are: for example non-ionic and anionic emulsifiers, such as polyoxyethylene fatty acid esters, polyoxyethylene fatty alcohol ethers, for example alkylaryl polyglycol ethers, alkylsulphonates, alkyl sulphates, arylsulphonates and protein hydrolysates; suitable dispersants are: for example lig- nosulphite waste liquors and methylcellulose.

Tackifiers 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, and also natural phospholipids, such as cephalins and lecithins, and synthetic phospholipids, can be used in the formulations. Other possible additives are mineral and vegetable oils. 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 and metal phtha- locyanine dyestuffs, and trace nutrients such as salts of iron, manganese, boron, copper, cobalt, molybdenum and zinc.

The formulations generally comprise from 0.1 to 95 per cent by weight of active compounds including the safeners, preferably between 0.5 and 90%.

The active compound combinations according to the invention are generally used in the form of finished formulations. However, the active compounds contained in the active compound combinations can also be mixed in individual formulations when used, i.e. in the form of tank mixes.

The novel active compound combinations, as such or in their formulations, can furthermore be used as a mixture with other known herbicides, finished formulations or tank mixes again being possible. A mixture with other known active compounds, such as fungicides, insecticides, acarici- des, nematicides, bird repellents, growth factors, plant nutrients and agents which improve soil structure, is also possible. For certain intended uses, in particular in the post-emergence method, it may furthermore be advantageous to include, as further additives in the formulations, mineral or vegetable oils which are tolerated by plants (for example the commercial preparation “Rako Binol”), or ammonium salts such as, for example, ammonium sulphate or ammonium thiocyanate.

The novel active compound combinations can be used as such, in the form of their formulations or the use forms prepared therefrom by further dilution, such as ready-to-use solutions, suspensions, emulsions, powders, pastes and granules. They are used in the customary manner, for example by washing, spraying, atomizing, dusting or scattering.

The advantageous effect of the crop plant compatibility of the active compound combinations/compositions according to the invention is particularly highly pronounced at certain amounts of herbicide and safener.

The amounts of the active compound combinations according to the invention applied can be varied within a certain range; they depend, inter alia, on the weather and on soil factors. In general, the application rates of the herbicide are between 0.1 and 1000 g per ha, preferably between 0.1 and 10 g per ha.

In general, the application rates of the safener are between 1 and 1000 g per ha, preferably between 10 and 200 g per ha. In seed treatment applications the application rates of the safener are between 0,01 and 2 g per kg seed, preferably between 0, 1 and 1 g per kg seed.

The active compound combinations/compositions according to the invention can be applied before and after emergence of the plants, that is to say by the pre-emergence and post-emergence method.

Use Examples:

Seed Treatment; pre-emergence

A) Method Description

For the safener seed treatment, sufficient seeds of the respective crops (spring wheat, TRZAS; spring barley, HORVS; maize, ZEAMA) were weighed into screw top glass bottles approximately twice the volume of the seeds.

The specified safeners, formulated as wettable powder (WP) were weighed out so that the specified rates (g a.i./kg seed) would be obtained, dissolved in water (1ml water per lOg of seeds), and added to the seeds to produce a slurry.

The bottles were capped and then placed in an overhead shaker (set at medium speed for ca. 60 minutes) so that the seeds were evenly coated with the slurry. The bottles were uncapped and the seeds were either placed on paper and dried for an interval of 3-4 hours prior to sowing, or directly sown. Seeds were placed in sandy loam soil in pots of a diameter of 7-8 cm, and covered with soil.

Pre-emergence application of the specified herbicides was done subsequently, on two sets of plants: a) seed treatment with safener, as described above b) no safener treatment

The herbicides were formulated as WP and was sprayed onto the soil surface as an aqueous suspension at an equivalent water application rate of 3001/ha.

After application, the test plants were kept in the greenhouse under good growth conditions. At intervals up to 4 weeks after application (=28 days after treatment; DAT), % crop damage observed on the treated plants was scored visually in comparison to control plants that had not received any safener or herbicide treatment.

Values in the table below are mean values of at least 2 replicates. The effectiveness of the safener treatment is displayed as: Reduction [Difference] = herbicide damage without safener - herbicide damage with safener Reduction [%] = (Reduction [Difference] * 100) / herbicide damage without safener B) Tables with Data
