Description

(54) HERBICID MEANS Herbicidal agent is effective in both pre-emergence and post-emergence applications. The recommended doses for selective destruction of weed plants in crops of cultivated plants are in the range of 2-10 kg / ha (according to the active substance). An important positive quality of operating venues, 1 is also low. Table 1

The process for the preparation of compounds of general formula I is based on the reaction of dialkyl or diarylphosphites with ketimines or aldimines. In tab. 1 shows compounds of general formula I. Proposition 1 and e II and e

Example 1. Pre-emergence application.

Seeds of weeds and cultivated plants were sown in the prepared soil and soon after that the soil was treated with compounds of the general formula in the form of a 50% wettable powder or a 20% emulsion concentrate at a flow rate of 600 liters of water / ha.

Evaluation of the herbicidal action was carried out on the 28th day after tillage on the tonal scale:

1-95% of plants destroyed;

9 - no effect.

The results of the experiment are presented in table. 2

Table 2

Example 2. Post-harvest application. Experimental plants in a leafless or two leaf stage were treated with compounds of the general formula I in the form of a 50% wettable powder or 20%

emulsion concentrate. Evaluation of the results was carried out on day 21 after treatment of the plants. The rating scale is the same as in example 1. The results of the experiment are summarized in table. 3

Claims (2)

Continuation The numbers of compounds in tables 2 and 3 correspond to the numbers in table 1. The data presented in table. 2 and 3 indicate a high herbicidal activity of compounds of general formula I and the selectivity of their action. Claims of the invention A herbicidal agent containing an active substance from the group of organophosphorus compounds and auxiliary components from among fillers and solvents, characterized in that, in order to increase efficiency, a compound of the general formula 5 10 15 is used as an active substance (R OLP-t -NHBO R where R is hydrogen or methyl; R2 -C-Cz-alkyl or phenyl; R is C-C4-alkyl, methoxyethyl, phenyl or benzyl; R is GI-C4-alkyl or phenyl, in an amount of 20-70 weight .%.
