Description

containing Uracil and Carbamate Derivat ives The present invention is concerned with herbicidal preparations containing and a Herbicidal mixtures containing different active substances have been frequently used they serve the purpose of roying more completely a larger number of types of plants in a single treatment than is possible by the individual use of the individual Most herbicides when used in mixtures however only produce the action that they would show when used On the other an action which or is different the sum of the separate actions of the individual components is very rare and not foreseeable since predictions in this field are not possible because of the present lack of knowledge of the mechanisms of action on which such an action is The present invention provides a herbicidal preparation which comprises of the formula arbamate of the general formula in which represents aryl or substituted by halogen alkyl alkyl thio 3 nitro or aralkyl an aliphatic hydrocarbon a mononuclear or polynuclear cycloaliphatic hydrocarbon group or a furfuryl and represents a hydrogen atom or an aliphatic hydrocarbon or and together with the adjacent nitrogen atom represent a heterocyclic group that may contain at least one further nitrogen oxygen hetero represents an unsubstituted or terminally halogenated aliphatic hydrocarbon and represents a hydrogen atom or an alkyl It is found that the herbicidal preparations of the present invention exhibit a better herbicidal action than the sum of the total action of the individual components when used Particularly suitable carbamates are those in which represents an unsubstituted phenyl group or a group of the formula in which n represents or 3 and each X represents a halogen a halogenalkyl an an alkoxy an alkylmercapto or a or so that the tituents represented by X may be identical represents a hydrogen represents an alkenyl or alkynyl group containing 1 to 4 carbon atoms which if be terminally The preparations of the present invention for even when in an amount that lies at the minimum action limit of the individual an adequate herbicidal action against weeds whereas if the components of the preparations were used alone in the same they would adequately comba or would not comba the weeds a A this broad aotion ai the eve email amounts of about 1 to the preparations show advantage a Beta beets selectivity cultivated for example whic are not damaged the preparations are used in the of the preparations against grasses should also be pa sinc use of individual is the present invention also provides a method of controllin wherein a living plant is treated a preparation defined The present invention further provides method of controlling wherein a crop area is with a herbioidal preparation as relative proportions of the individual components in the preparations of the present invention nay vary within wide and in each dependent on the desired degree of combatting or undeslred on type of weeds or to o the age of the weeds or on the prevailing weather as well as on technique of i no possible a priori to specify a particular ratio of which would equally all it has on the other hand been established tha the effects produced not striotly dependent particular It easily possible for an by appropriate preliminary to ascertain the particular ratio for ah intended In general the proportion of the to the within the of from 10 1 to from to 2 by sugar beetroot and but these amounts be in special preparations are preferably up form that normally used for they be up fo dusting liquid emulsions the addition of carriers or diluents if of wetting dispersin agents well as of fertilisers othe Suitable liquid carriers minera oils or other organic for example c carbo dimethylformamide and th As sol d there may fo Attaolay and other there may be for produota for ethox polyglyool po glyool alky alkylar kyl lauryl fatty oxide Pasto a ethox ted polyoxyprop Papaver Baphanus vulgarity Solanua Spergula Stellaria Polygonum Polygonua Polygonum Setaria Viol Poa Avena Anagallie Atrlplex p Euphorbia o Sinapie Sonohue Veronioa individual components o the preparations according to present invention already been as for German Patent Specification and oarbaao Belgian Patent Carbamates of the general fonaula be used according to the present are listed I o compound Compound of compound Physical constant 35 carbamate 41 42 43 44 47 Compound ISame of oompovmd Physical constant 112 C 64 j 129 65 0 5 0 s 72 0 carbamate oarbanate A einllar biologloal aotion shown by the o the other carbamates insufficientOCRQuality
