Description

SELECTIVE HERBICIDES BASED ON CARBAMOILTRIAZOLINOMAS AND HETEROARYLIOXYACETAMIDES FIELD OF THE INVENTION The invention relates to new synergistic combinations of active ingredients, herbicides, which are constituted by known carbamoyltriazolinones, on the one hand, and known per-heteraarilaxyacetamides, on the other hand and which can be used with a particularly good success for the selective struggle contributed to the weeds in various crops of useful plants. BACKGROUND OF THE INVENTION Carbamoyltriazolinones already constitute, as known herbicides, the subject of a series of patent applications (see EP-A 294666, EP-A 370293, EP-A 391187, EP-A 398096, EP-A 399294, EP-A 415196, EP-A 477646). The known carbamoyltriazolinones have, however, a series of failures in their activity, especially against monocotyledonous weeds. Heteroaryloxyacetamides also constitute, as active herbicides against monocotyledonous weeds, the subject of a series of patent applications (see EP-A 5501, EP-A 18497, EP-A 29171, EP-A 94514, EP-A 100044, EP-A 100045, EP-A 161602, EP-A 195237, EP-A 348734, EP-A 348737). The known heteroaryloxyacetamides are not active, however, in the same way against all monocotyledonous weeds. Surprisingly it has now been found that a number of herbicidal active compounds, known from the group RFF: 2 ^ 338 formed by the carbamoyltriazolinones in conjunction with known herbicidal active compounds from the group consisting of the heteroaryloxyacetamides, show an excellent synergistic effect with respect to the effect against weeds and which can be used with particular preference mode of combined preparations of broad activity for the selective fight against both the mopacatiledópeas weeds and against the dicotyledonous, in the pre-bud and past-shoot processes, in crops of mopo-cotyledonous and dicotyledonous useful plants, such as, for example, corn and soybeans.

As examples of the compounds of the formula (II), to be used as components of the mixtures according to the invention, mention may be made in particular of: N-methyl-N-phenyl-a- (5-trifluoromethyl-1,3,4- thiadiazol-2-yl-oxy) -acetyl, N-ethyl-N-phenyl-a- (5-trifluoromethyl-1,3,4-thiadiazol-2-yl-oxy) -aceta ida, Nn-propyl-N -phenyl-a- (5- trifluoromethyl-1,3,4-thiadiazol-2-yl-oxy) -acetamide, Ni-propyl-N-phenyl-OI- (5-trifluoromethyl-1,3,4-thiadiazole- 2-yl-oxy) -acetamide, N-methyl-N- (4-fluoro-phenyl) -OÍ- (5-trifluoromethyl-1,3,4-thiadiazol-2-yl-oxy) -acetamide, N -ethyl-N- (4- fluoro-phenyl) -o; - (5-trifluoromethyl-1,3,4-thiadiazol-2-yl-oxy) -acetamide, Nn-propyl-N- (4-fluoro-phenyl) -a- (5-trifluoromethyl), 3,4 -thiadiazol-2-yl-oxy) -acetamide, Ni-propyl-N- (4-fluorophenyl) -a-! 5-trifluoromethyl-1,3,4-thiadiazol-2-yl-oxy) -aceta- Measure, N-mstyl-N- (4-chloro-phenyl) -a- (5-trifluoromethyl-1,3,4-thiadiazol-2-yl-oxy) -acetamide, N-ethyl-N- (4-chloro) phenyl) -a- (5-trifluoromethyl-1,3,4-thiadiazol-2-yl-oxy) -acetamide, -n-propyl-N- (4-chloro-phenyl) -a- (5-trifluoromethyl) 1, 3, 4-thiadia-zol-2-yl-oxy) -acetamide and Ni-propyl-N- (4-chloro-phenyl) -a- (5-trifluoromethyl-1,3,4-thiadiazole-2-) il-oxy) -acetamide. The compound Ni-propyl-N- (4-fluoro-phenyl) -a- (5-trifluoromethyl-1,3,4-thiadiazol-2-yl-oxy) -acetamide - designated in the application examples as compounds (II -l) - must be singled out as a component of the mixture of formula (II). The compounds of the formulas (I) and (II) have been described in the patent applications or in the specifications of the aforementioned patents. It has now been found, surprisingly, that the above defined active compound combinations, consisting of carbamoyltriazolinones of the formula (I) and the heteroaryloxyacetamides of the formula (II), exhibit a particularly high herbicidal activity and that they can be used in various crops for the selective fight against weeds. Surprisingly, the herbicidal activity of the active compound combinations according to the invention is considerably greater than the sum of the effects of the individual active products. Therefore a real synergistic effect is not predictable and not only a complement of the effects. The new combinations of active products are perfectly compatible with many crops, attacking the new combinations of active products also with weeds that are difficult to combat otherwise, such as Portulace and Xanthium types. The new combinations of active products therefore represent a valuable enrichment of the selective herbicides. The active compound combinations according to the invention can be used, for example, on the following plants: Dicotyledonous bad herbs of the kinds; Sinapis, Lepi-dium, Galium, Stellaria, Matricaria, Anthemis, Galinsoga, Chenopodi m, Urtica, Senecio, Amaranthus, Portulaca, Xanthium, Co volvulus, Ipomoea, Polygonum, Sesbania, Ambrosia, Cirsium, Carduus, Sonchus, Rorippa, Rotala, Lindernia, Lamium, Veronica, Abutilon, Emex, Sida, Datura, Viola, Geleo-psis, Papaver, Centaurea, Trifolium, Ranunculus, Taraxum.

Monocotyledonous crops of the classes; Oryza, Zea, Tricicuym, Hordeum, Oats, Sécale, Sorghum, Panicum, Saccha-rum, Ananas, Asparagus, Allium. The use of the combinations of active compounds according to the invention is, however, not limited in any way to these classes, but they also extend equally over other plants. The synergistic effect of the active compound combinations according to the invention is especially marked with certain concentration ratios. However, the proportions by weight of the active products in the combinations of active products can vary within: a relatively broad range. In general, they correspond, per 1 part by weight of active compound of the formula (I), from 0.001 to 1000 parts by weight, preferably 0, From 1 to 100 parts by weight and, especially preferably, from 0.1 to 10 parts by weight of active compound of the formula (II). The active compounds can be converted into the customary formulations, such as solutions, emulsions, sprayable powders, suspensions, powders, dusting agents, pastes, soluble powders, suspension-emulsion concentrates, natural and synthetic materials impregnated with the active compound, as micro-encapsulated in polymer materials. These formulations are prepared in a known manner, for example by mixing the active ingredients with extender materials, that is, with liquid solvents and / or solid excipients, where appropriate, using surfactants, that is, emulsifiers and / or dispersants. I'o foam generating means. In the case of using water as extender, for example, organic solvents can also be used as auxiliary solvents. Suitable liquid solvents are, in particular, aromatics, such as xylene, toluene, or alkylnaphthalenes, chlorinated aromatics and chlorinated aliphatic hydrocarbons, such as chlorobenzenes, chloroethylenes or methylene chloride, aliphatic hydrocarbons, such as cyclohexanes. hexane or paraffins, for example, fractions of crude oil, mineral and vegetable oils, alcohols, such as butanol, or glycol, as well as their esters and ethers, ketones, such as acetone, methyl ethyl ketone, methyl isobutyl ketone, or cyclohexanone, strongly polar solvents, such as dimethylformamide and dimethyl sulfoxide, as well as water. Suitable solid excipients are, for example, ammonium salts and natural molten minerals, such as kaolins, clays, talc, chalk, quartz, attapalgite, montmorillonite or diatomaceous earth and molten synthetic minerals, such as acid. silicon, highly dispersed, aluminum oxide and silicates as solid excipients for granulates come into consideration: for example, broken and fractionated natural minerals such as calcite, marble, pumice, sepiolite, dolomite, as well as synthetic granules of inorganic and organic flours, as well as granulates of organic materials, such as sawdust, coconut husks, corn ears and tobacco stems; Examples of suitable emulsifiers and / or foam generators are: nonionic and anionic emulsifiers, such as polyoxyethylenated esters of fatty acids, for example, alkylaryl polyglycol ether, alkylsulfonates, alkyl sulfates, arylsulphonates, such as albumin hydrolysates; Suitable dispersants are, for example, lithium lixivities of lignin and methylcellulose. In the formulations, adhesives such as carboxymethylcellulose, natural and synthetic polymers powdery, granulated or in the form of latex, such as gum arabic, polyvinyl alcohol, polyvinyl acetate, as well as natural phospholipids, such as cephalin and lecithin, and synthetic phospholipids. Other additives can be mineral and vegetable oils. Dyes, such as inorganic pigments, for example, iron oxide, titanium oxide, ferrocyanic blue and organic dyes, such as alizarin dyes, metal azo and phthalocyanine dyes and trace nutrients, such as salts of iron, manganese, boron, copper, cobalt, molybdenum and zinc. The formulations usually contain between 0,:. up to 95% by weight of active substance, preferably between 0.5 and 90%. The combinations of active products according to the - 1? -invention will be used, in general, as formulations ready for their use. The active products, contained in the combinations of active products, can be mixed in the case of; its application, in individual formulations, that is to say that they can be used in the form of tank mixes. The new active compound combinations can find application as such or in their formulations as well as in a mixture of other known herbicides, while ready-to-use formulations or tank mixtures are also possible. A mixture with other known active substances is also possible, such as fungicides, insecticides, acaricides, nematicides, protective substances against ingestion by birds, growth substances, nutrient substances of the plants and means for improving the structure of the ground. For certain purposes of application, especially in the post-sprouting process, it may also be advantageous to incorporate, in the form of other additional products, mineral or vegetable oils compatible with the plants (for example the usual "Oleo Dupont HE"). in commerce) or cthmonium salts, such as, for example, ammonium sulfate or ammonium rhodanide. The novel active compound combinations according to the invention can be used as such, in the form of their formulations or of the forms of application prepared therefrom by further dilutions, such as ready-to-use solutions, suspensions, emulsions, powders, pastes. and granulates. The use is carried out in the usual way, for example, by watering, spraying, spraying, spreading. The application rates of the active compound combinations according to the invention may vary within certain limits; These depend, among other things, on the climatology and the terrain factors. In general, the application amounts are between 5 g and 5 kg per ha, preferably between 20 g and 20 kg per ha, particularly preferably between 50 g and 1.0 kg per ha. The active compound combinations according to the invention can be applied both before and after the outbreak of the plants, ie in pre-emergence and post-emergence procedures. The good herbicidal effect of the new combinations can be seen by means of the following examples. While the individual active products have weaknesses in their herbicidal effect, the combinations present, as a rule, a very good weed-destroying effect, which goes beyond the simple sum of the effects. A synergistic effect is presented in the herbicides provided that the herbicidal effect of the combination of the active products is greater than that of the active products applied individually. The expected effect for a given combination of two herbicides can be calculated as follows (see Colby, S. R.; "Calculating synergistic and antagonistic responses of herbicide combinations", Weeds 15, pages 20-22, 1967): If X =% damage caused by herbicide A (active product of formula I) with an application amount p kg / ha and Y =% damage caused by herbicide B (active product of formula II) with an application amount q kg / ha and E = expected damage caused by herbicides A and B with application quantities p and q kg / ha, then E = X + Y- (X * Y / 100).

If the actual damage is greater than calculated, then the combination will be over-additive in its effect, that is to say it shows a synergistic effect. It is clear from the following examples that the herbicidal effect of the active compound combinations according to the invention on weeds is greater than that calculated, that is to say that the new combinations of active compounds have a synergistic effect. Application examples For the preparation of the preparations of active ingredients necessary according to the invention, the corresponding amounts of a water-dispersible powder formulation (P) of a carbamoyltriazo-linone of the formula (I) and a powdery formulation (WP) are weighed. water dispersible heteroaryloxy acetamide of the formula (II) and diluted with water to the desired concentration. The tests were carried out as follows: Pre-sprout / greenhouse test Seeds of the test plants are planted in normal soils and watered, after 24 hours, with the preparation of active product. In this case, the amount of water per unit area is kept constant conveniently. The concentration of active product in the preparation plays no role; the fundamental thing is only the sanctity used for the active product per unit area. After the treatment the test plants are kept in the greenhouse, under controlled conditions (temperature, humidity, light) until the evaluation. After three weeks the degree of deterioration of the plants is evaluated in% of damages compared to the development of the untreated control plants.
