EMPLOYMENT OF ARILURACILQ8 IN THE SEMI-SELECTIVE AND NON-SELECTIVE FIELD OF THE FIGHT AGAINST THE BAD HERBS. DESCRIPTION OF THE INVENTION The invention relates to the use of known aryluracils (or of aryl-thio-uracils- or of isomeric compounds of these uracils or aryl-thiouracils) for the semi-selective and non-selective fight against weeds. . Aryluracils (or aryl thio-uracils) are herbicides that are the subject of a series of patent applications (see WO-A 91/00278, US-P 4979982, US-P 5169430, EP-A 408382, EP -A 563384, US-P 5084084, US-P 5127935, US-P 5154755, DE-P 4327743, DE-P 4343451, DE-P 4414326). However, nothing has yet been made known about the use of the known aryluracils (or aryl- (thio) uracils) in the semi-selective and non-selective field of weed control. Surprisingly it has now been found that a series of known herbicidal active compounds from the group of aryluracils (or of the aryl thiouracils or of the isomeric compounds of these aryluracils or arylthiouracils) are suitable in a very good manner for the fight against monocotyledonous and dicotyledonous weeds in the semi-selective and non-selective field either alone or in conjunction with herbicidal active compounds known, for example, from the product classes of carboxylic acids, of diphenyl ethers , of the diazin (onas) or of the triazin (onas), of the

These formulations are prepared in known manner, for example by mixing the active ingredients with extender materials, that is, with liquid solvents and / or solid excipients, if appropriate, using surfactants, that is, emulsifiers and / or dispersants and / or foam generating means. When using water as a filler, it is also possible, for example, to use organic solvents as auxiliary solvents.

Suitable solid excipients are, for example, ammonium salts and the ground natural minerals, such as kaolins, clays, talc, chalk, quartz, attapulgite, montmorillonite or diatomaceous earth and ground synthetic minerals, such as silicic acid, highly dispersed, aluminum oxide and silicates as solid excipients for granulates are considered: 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, and the like. albumin hydrolysates; Suitable dispersants are: for example, sulfitic leaching of lignin and methylcellulose. In the formulations, adhesives such as carboxymethylcellulose, natural and synthetic polymers, powdered, granulated or in the form of latex, such as gum arabic, polyvinyl alcohol, polyvinyl acetate, as well as natural phospholipids, such as cefalin and lecithin, can be used. , 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, metallic azo and phthalocyanine dyes, and trace nutrients, can be employed. salts of iron, manganese, boron, copper, cobalt, molybdenum and zinc. The formulations generally contain between 0.1 to 95% by weight of active substance, preferably between 0.5 and 90%. The active compound combinations according to the invention will be used, in general, as ready-to-use formulations. The active products, contained in the combinations of active products, can be mixed in the case of their application, in individual formulations, ie they can be used in the form of tank mixes. The active compounds or the active compound combinations according to the invention can be used as such or in their formulations, as well as in a mixture of other known herbicides for controlling weeds, while formulations ready for use or mixtures are possible in turn. of tank. A mixture with other known active ingredients 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 it may also be advantageous to incorporate, in the form of other additional products, vegetable or mineral oils compatible with the plants (for example the commercially available "Dupont HE") or ammonium salts, such as as, for example, ammonium sulfate or ammonium rodanide. The active compounds and the active compound combinations according to the invention can be used as such, in the form of their formulations or in the application forms 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. In the application tests carried out, the compounds of the formula (I) or (la) showed - also in combination with the herbicides mentioned above in (a) to (e) of the second group, such as the isopropyl ammonium salt of N-phosphonomethyl-glycine ("Roundup") - very good properties for the application in the semi-selective and non-selective field in the fight against weeds. It is noted that in relation to this date, the best method known to the applicant to carry out the aforementioned invention, is that which is clear from the present description of the invention. Having described the invention as above, property is claimed as contained in the following:
