专利摘要:
A composition containing at least one compound of the formula <IMAGE> (I) in which R is alkyl, alkenyl, alkinyl, halogenoalkyl or alkoxyalkyl, R1 is alkoxyalkyl or dialkoxyalkyl, R2 is alkyl or alkoxy, and x is oxygen or sulfur and n is 0, 1, 2 or 3. The compounds have a strong herbicidal effect against various weeds together with a broad selectivity in regard to agricultural plants, particularly potatoes, cotton, peanuts, carrots and rice.

(54) HERBICID MEANS
,; - - -.one . ; ; //
The invention relates to chemical agents for controlling weeds and undesirable vegetation (ai), namely, to a terbicidal agent containing an active principle from among carbohydrate-carboxylic acid derivatives and auxiliary components from a group of liquid or solid nosyogels, surfactants, etc.
A herbicidal agent is known, the active principle of which is E-methoxycarbonylamino-phenyl ester of 3-methylcarbanilic acid and. its analogues 1.
The prototype of the invention is herbicidal agents on the axis of carbamic acid derivatives. These include, for example, an agent based on urethanes-3-Calkyloxy-Idyl-alkylthiocarbonylinol-phenyl esters of M-allyl-N-benelikarbamoyoy acid 2
However, the known herbicidal agents of this group are not sufficiently effective for certain types of weeds and are not selective for crops,
The aim of the invention is a new Herbicidal agent based on carbamic acid derivatives, possessing a pyuyoy gerbicide effect, activity and selectivity of action.
This is achieved by using a carbamic acid derivative of the general formula, 1 -

The content of the active principle in the herbicidal agent ranges from 1 ° C to 80% by weight.
The forms of application of the active substances are ordinary: solutions, emulsions, pastes, powders, etc. They are prepared by known methods.
Recommended doses of the active principle for the selective destruction of weed plants range from 0.5 to 5 kg / ha.
The method of obtaining compounds of the general formula. based on the reaction of the corresponding aryl chloroformates with N-substituted anilines in the presence of a hydrogen chloride accelerator. They are also prepared by reacting 3-acylaminophenols with N-arylcarbamyl chloride or other known methods.

Example
experience. .
Experimental plants grown under greenhouse conditions up to a certain stage of development are treated with preparative forms of the active substances with a preparation consumption rate of 600 l / ha, which corresponds to 5 kg / ha of the active substance. Evaluation of the herbicidal action was carried out after 3 weeks post processing. The results of the experiment are given in table. one.
