专利摘要:
A herbicidal composition comprising, as active ingredients, a compound represented by the following formula I: <CHEM> and at least one compound selected from 2-chloro-4-ethylamino-6-isopropylamino-1,3,5-triazine (common name: atrazine), 2-chloro-4-(1-cyano-1-methylethylamino)-6-ethylamino-1,3,5-triazine (common name: cyanazine), alpha -chloro-2'6'-diethyl-N-methoxymethylacetanilide (common name: alachlor) or 2-chloro-N-(2-ethyl-6-methylphenyl)-N-(2-methoxy-1-methylethyl)acetamide (common name: metolachlor). The composition according to the invention can control completely annual weeds as well as perennial weeds at a lower dose without having phytotoxicity on corn.

专利说明:

This invention relates to chemical weed control agents in crops of cultivated plants.
The aim of the invention is to increase the selectivity of the action of the germicidal composition based on a two-component synergistic mixture containing a derivative of sim-triazine.
As one of the components, the herbicidal composition contains a simm-triazine derivative of general formula I
but
СгН5Ш -№ЩЩ
where R is isopropyl or 2-cyanopropyl-2.
The compound of formula I, in which R is isopropyl is called atrazine. The compound of formula I, in which R is 2-cyanopropyl-2 is called cyanazine.
The second component of the herbicidal composition is a sulfonylurea derivative of general formula II.

The proposed herbicidal composition is prepared by mixing its main components I and II with the appropriate surfactants, fillers or solvents.
Preparative forms of the herbicidal composition may be emulsifiable concentrates, wettable powders, solutions, granules, etc.
The mass ratio of the compounds of formulas I and II of the herbicidal composition is 1: 0.005-0.32.
Example 1. Definition of Herbicidal Action. In special plastic boxes place sterile dry ground and sow seeds of experimental plants in it. The next day, before the plants emerge, the soil is treated with the corresponding preparative forms of the individual components of the composition and their mixtures.
The synergistic effect of the herbicidal composition is calculated according to the well-known Colby formula. It is considered confirmed if the observed degree of effect of the composition on the test plant exceeds the degree of effect calculated by the indicated Colby formula.
The results of the experiments are presented in table.1 and 2.
Example 2. Comparative Experiments Experimental plants grown in greenhouse conditions up to a height of 10 cm, sample

The proposed herbicidal composition and a lime composition based on atrazine or cyanazine and M- (2-fluoro-4-chloro-5-isopropoxyphenyl) -3,4,5,6-tetrahydrophthalimide (compound A) are bathed.
The herbicidal effect is determined 15 days after the treatment by weight of the test plants and is expressed as a percentage. The results of the experiments are presented in table.3.
The data presented indicate a high herbicidal activity of the proposed composition and its high selectivity of action.
