In tab. 1 shows the individual compounds of general formula I. From the data given in Table. 2, one can judge the herbicidal properties of the agent according to the invention.

Example 1. Pre-emergence application.

The seeds of the experimental plants (chlorine, bristles, shchiritsa, cabbage, sorrel, Yezhovnik and oats) were sown in a prepared soil and after 1 day they were treated with active substance preparations in the amount of 8.97 kg / ha. After processing, the vessels in which the seeds of the experimental plants were planted were placed in a greenhouse and kept there for two weeks. After this, the herbicidal effect was evaluated - the degree of damage to the treated plants in comparison with the control - untreated plants.

0% - no damage.

100% complete plant death.

The results of the experiment are given in table. 2

The numbers of the compounds correspond to their numbers in table. one.

Example 2. Post-harvest application.

Experimental plants (cabbage, chlorine, sorrel, leafberry, wild oats and beans) grown under greenhouse conditions to a certain age (the leaves of leguminous plants are almost completely flattened and the first three leaf leaves begin to form) were treated with preparations of active substances in an amount of 8.97 kg / ha 14 days after the treatment, the herbicidal effect was evaluated and expressed as a percentage as in Example 1.

The results of the experiment are given in table. 2

In the first case (pre-emergence application), the assessment was given to an average of seven species of plants, in the second (post-emergence application) it was estimated as an average for plant species.

The results of the experiments indicate a higher herbicidal activity of the compounds according to the invention in comparison with the known analogues, which are effective at a dose of 22.4 kg / ha.
