Description

(54) HERBICIDE, COMPOSITION

I,. The invention relates to chemical agents 1 for controlling weeds in crops of cultivated plants, namely, to herbicidal compositions containing the active ingredient and auxiliary components, J components. Herbicidal formulations based on derivatives of 2,6-diamino-1,3,5Iriazine containing an inert diluent and surfactant (l) are known. 10 However, as previously introduced as herbicides, the triazine derivatives maintain phytotoxicity up to two three years, which leads in subsequent years to damage to crops sensitive to herbicides of cultivated plants. The purpose of the invention is to increase the selectivity of the herbicidal composition. The goal is achieved by the fact that the herbicidal composition 20 based on an inert diluent and surfactant contains as an active ingredient a compound of the general formula 1 -J 25 apkyl, alkenyl.

The compounds of formula 1 are used to control undesired plants. They are used in the south to destroy sprays in general, for example, on industrial horses, on roadsides, on squares near agricultural landings.

, The amount of 6-amnnotrizindione used depends on the requirements of the final result, method of application, type of oats and plants, composition used, water conditions, foliage density, etc. of actors. Since this is influenced by a large number of factors, it is difficult to predict the consumption of a substance for

The actual content of the compound (rmula T) depends on its physical properties.

Many of the compounds of the invention compare with unusually high solubility in water, up to several lines. This is extremely convenient in the case of wrestling with roots and other perennial rn-kami with a deep root system, the eimer of the highly soluble in water) of the invention can be -methyl-3-cyclohexyl-6-dimethylamine-) azine-2.4 ( 1H, 3N) -dnon; the solubility of this compound in water at 25 ° C is about 3.2%.

At the same time, Johnson's grass (Saftjjiium Ivalepease) with four leaves, creeping weeds and three year leaves and a nuttedzh (CypentS rotnactw) from two leaves with tubers were treated with a seedling ambassador at a flow rate of 2.2 kg / ha. The treated and control plants were kept in the greenhouse for 16 days, then the vye species were compared with the control plants and visually evaluated for the treatment result.

Quantitative evaluation was carried out on a scale from 0 to 10. 10 means complete destruction, evaluation of O means no damage. They also made a qualitative assessment (damage type)} the letter C means chlorosis, and the letter Q indicates growth inhibition. In tab. 5 estimates are given for this test for some of the best compounds of the invention.

The results of testing herb formulations using the compound of the general formula I as an active component are given in Table. 6-11.
