4Ie BAYER AKIENGESELLSCHAFT Konzemverwaltung RP Patente Konzem 51368 Leverkusen Substituted triazolinones The invention relates to novel substituted triazolinones, to a number of processes for their preparation and to their use as herbicides.

It is known that certain substituted triazolinones, such as, for example, the compound 2-methyl-3- dimethylamino- 1- [N-(2,2-dimethyl- 1-propyl)aminocarbonyl]- 1,2,4-triazolin-5-one, possess herbicidal properties (cf. e.g. EP 431 390).

However, the herbicidal activity of these previously known compounds with respect to problem weeds, and their tolerance by important crop plants, is not completely satisfactory in all areas of application.

Novel substituted triazolinones have been found of the general formula (I) I 2 1 X ',8 in which Het represents a heterocycle of the formula Le A 29 399-PCT R R R I I

-6- Finally it has been found that the novel substituted triazolinones of the general formula possess herbicidal properties.

SSurprisingly, the substituted triazolinones according to the aivention, of the general formula display a considerably improved herbicidal activity with respect to problem weeds, while at the same time being tolerated to a markedly increased extent by important crop plants, in comparison with the substituted triazolinones known from the prior art, such as, for example, the compound 2methyl-3- dimethylamino- 1- dimethyl- 1-propyl)- aminocarbonyl]- 1,2,4which compounds are closely related chemically and in terms of their mode of action.

For working up, precipitated triethylamine hydrochloride is filtered off the filtrate is concentrated in vacuo, and the residue is taken up in 150 ml of dichloromethane, washed with three times 50 ml ofwater, dried over sodium sulphate and again concentrated in vacuo. The residue is recrystallized from cyclohexane.

Seeds of the test plants are sown in normal soil and, after 24 hours, watered with the preparation of the active compound. It is expedient to keep constant the amount of water per unit area. The concentration of the active compound in the preparation is of no importance, only the amount of active compound applied per unit area being decisive. After three weeks, the degree of damage to the plants is rated in damage in comparison to the development of the untreated control.

The figures denote: 0% no action (like untreated control) 100% total destruction In this test, for example, the compound according to Preparation Example 3 exhibits a marked superiority in activity, and also a considerably improved selectivity by crop plants, in relation to the prior art.
