Combination of herbicides and safeners

Description

DESCRIPTION

The invention relates to the technical field of the crop protection products, in particular herbicide/antidote combinations (active substance/safener combinations) which are outstandingly suitable for the use against competing harmful plants in crops of useful plants.

Some of the more recent herbicidal active substances which inhibit p-phydroxyphenylpyruvate dioxygenase (HPPDO) have very good use characteristics and can be employed at very low application rates against a broad spectrum of grass weeds and broad-leaved weeds (see, for example, M. P. Prisbylla et al., Brighton Crop Protection Conference—Weeds (1993), 731-738). However, many of these highly efficient active substances are not fully compatible with (i.e. not sufficiently selective in) some important crop plants such as maize, rice or cereals, so that their use is strictly limited. In certain crops, they can therefore not be employed, or at such low application rates that the desired broad herbicidal efficacy towards harmful plants is not guaranteed. Specifically, many of the abovementioned herbicides cannot be employed fully selectively against harmful plants in maize, rice, cereals or some other crops.

To overcome these disadvantages, it is known to employ herbicidal active substances in combination with a so-called safener or antidote. A safener for the purpose of the invention is a compound or a mixture of compounds which compensates for, or reduces, the phytotoxic properties of a herbicide towards useful plants without substantially reducing the herbicidal action against harmful plants.

The identification of a safener for a particular class of herbicides remains a difficult task since the exact mechanisms by which a safener reduces the harmful effect of herbicides are unknown. The fact that a compound in combination with a particular herbicide acts as a safener allows no conclusions as to whether such a compound also acts as a safener with other classes of herbicide. Thus, it has emerged that, when using safeners for protecting the useful plants from herbicide damage, the safeners may still have a number of disadvantages in many cases. These are:

the safener reduces the action of the herbicides against the harmful plants,

the useful-plant-protecting properties are insufficient,

in combination with a given herbicide, the spectrum of the useful plants in which the safener/herbicide is to be used is insufficiently wide,

a given safener may not be combined with a sufficiently large number of herbicides.

It was an object of the present invention to identify compounds which, in combination with the abovementioned herbicides are suitable for increasing the selectivity of these herbicides towards important crop plants.

Surprisingly, a group of compounds has now been found which, together with specific herbicides which act as HPPDO inhibitors, increase the selectivity of these herbicides towards important crop plants.

The invention therefore relates to a herbicidally active composition comprising a mixture of

A a herbicidally active amount of one or more compounds of the formula (I)

The safeners (antidotes) of the formulae (II)-(VIl) and the compounds of group (b), for example safeners of the abovementioned groups a) to h), reduce or prevent phytotoxic effects which may occur when using the herbicidal active substances of the formula (I) in crops of useful plants without substantially affecting the efficacy of these herbicidal active substances against harmful plants. This allows the field of application of conventional crop protection products to be widened quite considerably and to be extended to, for example, crops such as wheat, barley, maize and other crops in which use of the herbicides was hitherto impossible, or only limited, that is to say at low rates and with a restricted spectrum.

The herbicidal active substances and the mentioned safeners can be applied together (as a readymix or by the tank mix method) or in succession in any desired sequence. The weight ratio of safener:herbicidal active substance may vary within wide limits and is preferably in the range of from 1:100 to 100:1, in particular 1:10 to 10:1. The optimum amounts of herbicidal active substance and safener which are used in each case depend on the type of the herbicidal active substance used or on the safener used and on the species of the crop stand to be treated and can be determined in each individual case by simple routine preliminary experiments.

The main fields of application for the combinations according to the invention are, in particular, maize and cereal crops such as, for example, wheat, rye, barley, oats, rice, sorghum, but also cotton and soybeans, preferably cereals, rice and maize.

Depending on their properties, the safeners employed in accordance with the invention can be used for pretreating the seed of a crop plant (seed dressing), or be incorporated into the seed furrows prior to sowing or applied together with the herbicide before or after plant emergence. The pre-emergence treatment includes not only treatment of the area under cultivation prior to sowing and treatment of the areas under cultivation where the seeds have been planted but the plants have not yet emerged. The joint application together with the herbicide is preferred. To this end, tank mixes or readymixes may be employed.

The application rates of safener required may vary within wide limits depending on indication and herbicidal active substance used and are generally in the range of from 0.001 to 5 kg, preferably 0.005 to 0.5 kg, of active substance per hectare.

The present invention therefore also relates to a method of protecting crop plants from phytotoxic side effects of herbicides of the formula (I) which comprises applying an antidote-effective amount of a compound of the formula (II), (III), (IV), (V), (VI), (VII) and/or (selected from the group (b)) to the plants, plant seeds or the area under cultivation, either before, after or simultaneously with, the herbicidal active substance A of the formula (I).

The herbicide/safener combination according to the invention may also be employed for controlling harmful plants in crops of genetically engineered plants which are either known or still to be developed. As a rule, the transgenic plants are distinguished by particular, advantageous properties, for example by resistance to certain crop protection agents, resistance to plant diseases or pathogens causing plant diseases such as particular insects or microorganisms such as fungi, bacteria or viruses. Other particular properties relate, for example, to the harvested material in terms of quantity, quality, storing properties, composition and specific constituents. Thus, there are known transgenic plants with an increased starch content or with an altered starch quality, or those where the harvested material has a different fatty acid composition.

The use of the combinations according to the invention in economically important transgenic crops of useful plants and ornamentals, for example cereals such as wheat, barley, rye, oats, sorghum and millet, rice, cassava and maize, or else crops of sugar beet, cotton, soya, oilseed rape, potatoes, tomatoes, peas and other vegetables.

When the combinations according to the invention are applied in transgenic crops, effects on harmful plants to be observed in other crops are frequently accompanied by effects which are specific for application in the transgenic crop in question, for example an altered or specifically widened weed spectrum which can be controlled, altered application rates which may be used, preferably good compatibility with the herbicides to which the transgenic crop is resistant, and altered growth and yield of the transgenic crop plants.

The invention therefore also relates to the use of the combination according to the invention for controlling harmful plants in transgenic crop plants.

The safeners of the formulae (III)-(VII) and of group (b) and their combinations with one or more of the abovementioned herbicidal active substances of the formula (II) can be formulated in various ways, depending on the biological and/or chemico-physical parameters specified. Examples of possible formulations which are suitable are:

Wettable powders (WP), emulsifiable concentrates (EC), water-soluble powders (SP), water-soluble concentrates (SL), concentrated emulsions (BW) such as oil-in-water and water-in-oil emulsions, sprayable solutions or emulsions, capsule suspensions (CS), oil- or water-based dispersions (SC), suspoemulsions, suspension concentrates, dusts (DP), oil-miscible solutions (OL), seed-treatment products, granules (GR) in the form of microgranules, spray granules, coated granules and adsorption granules, granules for soil application or broadcasting, water-soluble granules (SG), water-dispersible granules (WG), ULV formulations, microcapsules and waxes.

These individual formulation types are known in principle and described, for example, in: Winnacker-Küchler, “Chemische Technologie” [Chemical Technology], Volume 7, C. Hauser Verlag Munich, 4th Edition 1986; Wade van Valkenburg, “Pesticide Formulations”, Marcel Dekker N.Y., 1973; K Martens, “Spray Drying Handbook”, 3rd Edition 1979, G. Goodwin Ltd. London.

The formulation auxiliaries which may be required, such as inert materials, surfactants, solvents and other additives are also known and described, for example, in: Watkins, “Handbook of Insecticide Dust Diluents and Carriers”, 2nd Ed., Darland Books, Caldwell N.J., H.v. Olphen, “Introduction to Clay Colloid Chemistry”; 2nd Ed., J. Wiley & Sons, N.Y.; C. Marsden, “Solvents Guide”; 2nd Ed., Interscience, N.Y. 1963; McCutcheon's “Detergents and Emulsifiers Annual”, MC Publ. Corp., Ridgewood N.J.; Sisley and Wood, “Encyclopedia of Surface Active Agents”, Chem. Publ. Co. Inc., N.Y. 1964; Schönfeldt, “Grenzflächenaktive Äthylenoxidaddukte” [Surface-Active Ethylene Oxide Adducts], Wiss. Verlagsgesell., Stuttgart 1976; Winnacker-Küchler, “Chemische Technologie” [Chemical Technology], Volume 7, C. Hauser Verlag Munich, 4

th

Edition 1986.

Based on these formulations, it is also possible to prepare combinations with other substances which act as crop protection agents, such as insecticides, acaricides, herbicides, fungicides, and also with safeners, fertilizers and/or growth regulators, for example in the form of a readymix or tank mix.

Wettable powders are preparations which are uniformly dispersible in water and which, besides the active substance, also comprise ionic and/or nonionic surfactants (wetting agents, dispersants), for example polyoxyethylated alkylphenols, polyoxyethylated fatty alcohols, polyoxyethylated fatty amines, fatty alcohol polyglycol ether sulfates, alkanesulfonates, alkylbenzenesulfonates, sodium lignosulfonate, sodium 2,2′-dinaphthylmethane-6,6′-disulfonate, sodium dibutylnaphthalenesulfonate, or else sodium oleoylmethyltaurinate, in addition to a diluent or inert substance. To prepare the wettable powders, the herbicidally active substances are ground finely, for example in customary apparatus such as hammer mills, blower mills and air-jet mills, and simultaneously or subsequently mixed with the formulation auxiliaries.

Emulsifiable concentrates are prepared, for example, by dissolving the active substance in an organic solvent, such as butanol-, cyclohexanone, dimethylformamide, or else higher-boiling hydrocarbons such as saturated or unsaturated aliphatic hydrocarbons or alicyclic hydrocarbons, aromatics or mixtures of the organic solvents with the addition of one or more ionic and/or nonionic surfactants (emulsifiers). Examples of substances which can be used as emulsifiers are: calcium alkylarylsulfonates such as calcium dodecylbenzenesulfonate, or nonionic emulsifiers such as fatty acid polyglycol esters, alkylaryl polyglycol ethers, fatty alcohol polyglycol ethers, propylene oxide/ethylene oxide condensates, alkyl polyethers, sorbitan esters, for example sorbitan fatty acid esters or polyoxyethylene sorbitan esters, for example polyoxyethylene sorbitan fatty acid esters.

Dusts are generally obtained by grinding the active substance with finely distributed solid substances, for example talc, natural clays such as kaolin, bentonite and pyrophyllite, or diatomaceous earth.

Suspension concentrates can be water- or oil-based. They can be prepared, for example, by wet grinding using commercially available bead mills with or without an addition of surfactants, for example those which have already been mentioned above in the case of the other formulation types.

Emulsions, for example oil-in-water emulsions (EW), can be prepared, for example, by means of stirrers, colloid mills and/or static mixers using aqueous organic solvents in the presence or absence of surfactants which have already been mentioned above, for example, in the case of the other formulation types.

Granules can be prepared either by spraying the active substance onto adsorptive, granulated inert material or by applying active substance concentrates to the surface of carriers such as sand, kaolinites or granulated inert material with the aid of binders, for example polyvinyl alcohol, sodium polyacrylate or else mineral oils. Suitable active substances can also be granulated in the manner which is conventional for the preparation of fertilizer granules, if desired as a mixture with fertilizers. As a rule, water-dispersible granules are prepared by the customary processes such as spray drying, fluidized bed granulation, disk granulation, mixing with high-speed mixers, and extrusion without solid inert material.

For the preparation of disk, fluidized-bed, extruder and spray granules see, for example, processes in “Spray-Drying Handbook” 3rd Ed. 1979, G. Goodwin Ltd., London; J. E. Browning, “Agglomeration”, Chemical and Engineering 1967, pages 147 et seq.; “Perry's Chemical Engineeres Handbook”, 5

th

Ed., McGraw-Hill, New York 1973, p. 8-57.

For further details on the formulation of crop protection products see, for example, G. C. Klingman, “Weed Control as a Science”, John Wiley and Sons, Inc., New York, 1961, pages 81-96 and J. D. Freyer, S. A. Evans, “Weed Control Handbook”, 5

th

Ed., Blackwell Scientific Publications, Oxford, 1968, pages 101-103.

As a rule, the agrochemical preparations comprise 0.1 to 99% by weight, in particular 0.1 to 95% by weight, of active substances of the formula (II)-(VII) and/or (b) or of the herbicide/antidote mixture of active substances (I) and (II)-(VII) and/or (b) and 1 to 99.9% by weight, in particular 5 to 99.8% by weight of a solid or liquid additive and 0 to 25% by weight, in particular 0.1 to 25% by weight of a surfactant.

In wettable powders, the active substance concentration is, for example, approximately 10 to 90% by weight, the remainder to 100% by weight being composed of customary formulation components. In the case of emulsifiable concentrates, the concentration of active substance is approximately 1 to 80% by weight. Formulations in the form of dusts comprise 1 to 20% by weight of active substance, sprayable solutions comprise approximately 0.2 to 20% by weight of active substance. In the case of granules, such as water-dispersible granules, the active substance content depends partly on whether the active compound is in liquid or solid form. The active substance content of the water-dispersible granules is, for example, between 10 and 90% by weight.

Besides this the abovementioned formulations of active substances may comprise, if appropriate, the adhesives, wetting agents, dispersants, emulsifiers, penetrants, preservatives, antifreeze agents, solvents, fillers, carriers, colorants, antifoams, evaporation inhibitors and pH and viscosity regulators which are customary in each case.

Components which can be used in combination with the herbicide/safener mixtures according to the invention in mixed formulations or in tank mixes are, for example, known active substances as they are described, for example, in Weed Research 26, 441-445 (1986), or “The Pesticide Manual”, 10

For use, the formulations which are in commercially available form are, if desired, diluted in the customary manner, for example using water in the case of wettable powders, emulsifiable concentrates, dispersions and water-dispersible granules. Preparations in the form of dusts, soil granules, granules for broadcasting and sprayable solutions are usually not diluted any further with other inert substances prior to use.

The necessary application rate of the herbicides of the formula (I) varies with the external conditions such as, inter alia, temperature, humidity and the nature of the herbicide used. It may be varied within wide limits, for example between 0.001 and 10.0 kg/ha or more of active ingredient, but it is preferably between 0.005 and 5 kg/ha.

The examples which follow are intended to illustrate the invention:

Biological Examples

1. Scoring the Damage

The damage to the plants is assessed visually in comparison with control plants using a scale of 0-100%:

0%=no noticeable effect in comparison with the untreated plant,

100%=treated plant dies.

2. Pre-emergence Herbicide Action and Safener Action

Seeds of monocotyledonous and dicotyledonous weed plants of crop plants are placed in sandy loam soil in plastic pots of 9 cm diameter and covered with soil. Alternatively, weeds found in rice cultivation under paddy rice conditions are, for the test, cultivated in waterlogged soil, the pots being filled with such an amount of water that the water reaches the soil surface or floods it by a few millimeters. The active substance combinations according to the invention, of herbicide and safener, which are formulated as emulsion concentrates and, in parallel experiments, the individual active substances formulated analogously are then applied to the surface of the soil cover in the form of emulsions at a water application rate of 300 I/ha (converted) or, in the case of rice, poured into the irrigation water, in each case in various dosages.

After the treatment, the pots are placed in the greenhouse and kept under good growth conditions. After the test plants have emerged after a test period of 3-4 weeks, the damage to the plants, or emergence damage, is scored visually by comparison with untreated controls. As illustrated by the test results, the herbicidal compositions according to the invention have a good herbicidal pre-emergence action against a broad spectrum of grass weeds and dicotyledonous weeds, while damage to crop plants such as maize, rice, wheat or barley or other cereals is markedly reduced by comparison with the use of the individual herbicides without safener, i.e. the herbicide damage is reduced by 30% up to 100%.

3. Post-emergence Herbicide Action and Safener Action

Seeds of monocotyledonous and dicotyledonous weed plants and of crop plants are placed in sandy loam soil in plastic pots, covered with soil and grown in the greenhouse under good growth conditions. Alternatively, weeds found in rice cultivation and rice are grown, for the test under paddy rice conditions, in pots in which water floods the soil surface by up to 2 cm, and cultivated during the growth phase. Approx. three weeks after sowing, the test plants are treated in the three-leaf stage. The active substance combinations according to the invention of herbicide and safener which are formulated as emulsion concentrates and, in parallel experiments, the individual active substances which are formed analogously are sprayed onto the green parts of the plants in various dosages at a water application rate of 300 I/ha (converted) and, after the test plants have been left in the greenhouse for three weeks under ideal growth conditions, the effect of the products was scored visually by comparison with untreated controls. In the case of rice or weeds found in rice cultivation, the active substances are also added direct to the irrigation water (application analogously to the so-called granule application) or sprayed onto plants and into the irrigation water. As the results, in particular those shown in Tables 17 and 18, demonstrate, the herbicidal compositions according to the invention have a goods herbicidal post-emergence activity against a broad spectrum of grass weeds and dicotyledonous weeds, while damage to crop plants such as maize, rice, wheat or barley or other cereals is markedly reduced by comparison with the use of the individual herbicides without safener, i.e. the herbicide damage is reduced by 30% up to 100%.
