The preparation is carried out according to usual methods (see the preparation eles). The active compounds according to the invention can be used as defoliants, desiccants, agents for removing harmful plants, especially for destroying weeds. By weeds, in the broadest sense, we must understand the plants that grow in places where they are unwanted. The fact that the substances according to the invention act as total or selective herbicides depends essentially on the amount used. The active products, according to the invention can be used, for example, in the following plants: Dicotyledonous bad herbs of the kinds: Sinapis Lepidium, Galium, Stellaria, Matricaria, Anthemis, Galinsoga, Chenopodium, Urtica, Senecio, Amaranthus, Portulaca, Xanthium, Convolvulus, Ipomoea, Polygonum, Sesbania, Ambrosia, Cirsium, Carduus, Sonchus, Solanum, Rorippa, Rotala, Lindernia, Lamium, Veronica, Abutilon, Emex, Datura, Viola, Galeopsis, Papaver, Centaurea, Trifolium, Ranunculus, Taraxacum.

The use of the active compounds according to the invention is, however, not limited in any way to these classes, but they also extend to other plants in the same way. The compounds are suitable, depending on the concentration, to completely combat the weeds, for example, in industrial and road installations and in roads and squares, with and without tree growth. In the same way, compounds can be used to control weeds in permanent crops, for example, in forest facilities, ornamental trees, fruit trees, vineyards, citrus trees, walnut trees, bananas, coffee, tea, rubber oil palm, cocoa, fruit-tea-berries and ornamental plants, ornamental and sporting plants and on surfaces - of meadows and to selectively control weeds in crops mono-annual. The compounds of the formula (I) according to the invention are suitable for the control of monocotyledonous and dicotyledonous weeds both in the pre-emergence procedure and in the post-emergence process. They show a high herbicidal activity and a broad spectrum of activity when they are used on the soil and on the aerial parts of the plants.
