It is known that substituted 1,2,4-oxadiazolidine-3,5-diones, for example 4- (3'-chlorophenyl) -2-methyl-1,2,4-oxadiazolidine-3,5- dione, have a herbicidal effect (British Patent No. 1,168,721, French Patent No. 1,512,127). Their action, however, is not satisfactory, as the undesirable plants are not sufficiently damaged. It was found that the substituted 1,2,4-oxadiazolidine-3,5-diones of the general formula I, in which R is an alkyl group of 1 - 8 carbon atoms, optionally a mono- or multi-substituted alkenyl group with 3 - 8 carbon atoms, an alkynyl group with 4 - 8 carbon atoms or a single-ring, double-ring or multi-ring alkyl group with 5 - 14 carbon atoms, optionally substituted with ethynyl group, have good herbicidal activity. The effect is especially visible on plants: Poa lamnua, Alopecurus myosaroides, Echinochloa, Crus-Gaul, Lamdum amplexicaule and Si- inscription arvensis when using 0.5 kg - 3 kg of sub ¬ active content per hectare, depending on pre- or post-emergence application. The active compounds are suitable, for example, for application to cereals, maize, sorghum or peanuts. The herbicides according to the invention are applied in the usual way, namely by applying the active ingredient to plant leaves or to the soil. The following examples illustrate the application of the compositions according to the invention as herbicides. The examples also illustrate the action of these agents in comparison with the known 4- (3'-chlorophenyl) -2-methyl-1,2,4-oxadiazimdine-3,5-dione (according to British patent specification No. 1,168,721 In the introduction, Table 1 summarizes the list of examples of active ingredients in the compositions according to the invention, together with their characteristics. Example I. In a greenhouse, seeds of Zea mays, Triticum aestivum Hordeum vul were sown in a greenhouse in a greenhouse. - gare, Oryza sativa, Gossypium hirsutum, Poa annua, Alopecurus myosuroides, Echinochloa crus-galli, Lamium amplexicaule and Sinapis arvensis. The soil was then treated with 2 kg of active ingredient per hectare of 4- (3'-tertiary butylcarbamoyloxyphenyl) 2-methyl-1,2,4-oxazolidine-3,5-dione, designated as substance I, and for comparison 2 kg of active ingredient per hectare of 4- (3, - chlorophenyl) -2-methyl-1,2,4-oxazolidine-3,5-dione designated as substance II. Both substances were dispersed in 500 liters of water per hectare. After 4-5 weeks, they showed the cultivated plants treated with substance I in comparison with those treated with substance II equal to 817213 81721 4 Table 1 ni; m Substituted 4- (3'-carbomoyloxy-phenyl) -2-methyl-l, 2,4-oxadiazolidine-3,5-diones of the general formula 1R methylisopropylbutyl- (2) -2-methyl-propyl- (l) - Tertiary butyl 1,3-dimethyl-butyl- (1) - 1-methyl-cyclopentyl- (1) - 1-chloro-butyl- (2) - allyl-2-vinyl- propyl- (2) - butyn- (l) -yl- (3) 2-ethynyl-propyl (2) - 4,7-methane-dn-danyl- (2) - cytcododecyl-l-ethynyl- cyclo- | hexyl- (l) - Summary formula structural formula 2 C13H15N805 C14H17N305 C14H17N305 C14H17N305 C ^ H ^ NjA C16H19N3Ofi C14H16N305 C13H13N305 C15H17N305 C ^ H13N305 C15H13N305 C15H13N305 C15H13N305 C15H13N305 C15H13N305 C15H13N305 C18 - 293.3 307.3 307.3 307.3 335.4 333.4 341.8 291.3 319.3 303.3 317.3 385.4 417.5 357.4 melting point ° C 114-116 136-138 122 115-117 113-115 75-77 85-87 120-122 90-92 solid liquid solid liquid 100-102 135 (with decomposition) 160-162 solid liquid not well tolerated. Substance I, on the other hand, showed a stronger herbicidal action. The results are summarized in Table 2 as substance II and has a herbicidal effect on all weeds by substance II.

The amount used was 5 kg of active ingredient per hectare, dispersed in 500 liters of water per hectare. After 4-5 weeks, all the plants were destroyed. EXAMPLE IV. The field of application on which Sinapis aryensis, Galinsoga parvi Lora, Chenodium album, Matricaria chamomilla, Avena fatua, Poa 'annua grew, the substance I was treated in the form of 4- (3'-III-order butyl-carbamoyloxy-phenyl) -2-methyl-1,2,4-oxadiiazoMdine-3,5-dione and for comparison substance II, in the form of 4- (3'-chlorophenyl) -2-methyl-1,2,4-oxazolidine -3,5-dione. At the time of spraying, the plants reached a growth height of 3-8 cm. 5 kg of active ingredient per hectare were used, dispersed in 500 liters of water per hectare. After a few days it was found that the weeds treated with substance I were more damaged than the plants treated with substance II. After 4 weeks, almost all the plants were destroyed. Biologically correspondingly active as substance I sa: 4- (3'-isopropyl-carbamoyloxyphenyl) 2-methyl-1,2,4-oxazolidine-3,5-dione, 4- (3 '-isobutyl-carbamoyloxyphenyl) 2-methyl-1,2,4-oxazolidine-3,5-dione, 4- (3'-buityl-) 2 (-carbamoyloxyphenyl) -2-methyl-1,2,4 -oxadiazolidine-3,5-dione. 4- (3 / -2-ethylene-propyl) 2 (-carbamoyloxyphenyl) 2-methyl-1,2,4-oxazolidine-3,5-dione. 4- (3'-allyl-carbamoyloxy-phenyl) 2-methyl-1,2,4-oxazolidine-3,5-dione 4- (3'-1-chloro-butyl) 2 (-carbamoyloxy-phenyl) - 2-methyl-1,2,4-oxaisolidine-3,5-dione 4- (3'-ethyl-cyclohexyl-) 1 (-carbamoyloxy-phenyl-2-methyl-1,2,4-oxazoazolidine-3 , 5-dione. 4- (3'-1-methyl-cyclopentyl-) 1 (-carbamoyloxy-phenyl) -2-methyl-1,2,4-oxadiazolidine-3,5-dione and '] "4- (3'-cyclododecyl-carbamoyloxy-phenyl) -2-methyl-1,2,4-oxadiazolidine-3,5-dione. Example 5 Mix 90 parts by weight of compound I with 10 parts by weight of N-methyl-a - -pyrrolidone and a solution suitable for use in the form of very fine drops is obtained. Example VI 20 parts by weight of the compound I are dissolved in a mixture consisting of 80 parts by weight of xylene and 10 parts by weight of an additive with 8-10 moles of oxide of ethylene and 1 mole of oleic acid N-monoethanolamide, 5 parts by weight of calcium dodecylbenzenesulfonic acid and 5 parts by weight of an additive with 40 moles of ethylene oxide and 1 'mole and castor oil. By pouring the solution into 100,000 parts by weight of water and spraying it, a dispersion is obtained containing 0.02% by weight of the active ingredient. Example VII. 20 parts by weight of the compound I are dissolved in a mixture consisting of 40 parts by weight of cyclohexanone, 30 parts by weight of isobutanol, 20 parts by weight of an additive with 7 moles of ethylene oxide and 1 mole of isooctylphenol and 10 parts by weight of an additive with 40 moles of ethylene oxide and 1 mole of castor oil. By pouring and spraying the solution in 100,000 parts by weight of water, an aqueous dispersion is obtained containing 0.02% by weight of the active ingredient. Example VIII. 20 parts by weight of the compound I are dissolved in a mixture consisting of 25 parts by weight of cyclohexanol, 65 parts by weight of a mineral oil fraction with a boiling point of 210-280 ° C and 10 parts by weight of an additive with 40 moles of ethylene oxide and 1 mole of oil castor. By pouring the solution into 100,000 parts by weight of water and spraying it onto it, an aqueous dispersion is obtained containing 0.02% by weight of the active ingredient. Example IX. 20 parts by weight of the active ingredient I are thoroughly mixed and ground in a hammer mill with 3 parts by weight of sodium diazobutylnaphthalene-a-sulfonic acid, 17 parts by weight of sodium lignosulfonic acid from sulphite liquors and 60 parts by weight of powdered gel silicic acid. By spraying the mixture into 20,000 parts by weight of water, a spray liquor is obtained containing 0.1% by weight of the active ingredient. Example X. 3 parts by weight of compound I are mixed with exactly 97 parts by weight of fine-grained kaolin. This gives a dust with 3% by weight of active ingredient. Example XI. 30 parts by weight of compound I are thoroughly mixed with a mixture consisting of 92 parts by weight of powdered silicic acid gel and 8 parts by weight of paraffin oil sprayed on the surface of this silicic acid gel. A formulation of an active ingredient with good adhesion is thus obtained. 40 PL PL
