Description
SPECIFICATION
Herbicidally active diurethanes and their manufacture and use
The present invention is concerned with new diurethanes, with processes for the manufacture of these compounds and with their use as herbicidal agents.
The herbicidal action of diurethanes is already known. Known active substances of this kind have a selective herbicidal action especially in beet crops (German Patent Specification No. 1.567,151) or in soya beans (German Patent Specification No. 2,638,897).
The problem upon which the present invention is based has been to develop a herbicidal agent which has a very good action against weeds that are difficult to control and, at the same time, exhibits a tolerance especially in cotton crops.
This problem is solved according to the present invention by the compounds of the general formula i, as defined below.
The present invention accordingly provides compounds of the general formula I
in which R1 represents a C1-C4-alkyl or phenylethyl group,
R2 represents a C1-C4-alkyl, halogeno-C1-C4-alkyl, C2C,4-alkenyl, halogeno-C2-C4-alkenyl, C2-C4-a Ikynyl or ha logeno-C2-C4-a Ikynyl group,
Y represents a hydrogen or fluorine atom and
X represents an oxygen or sulphur atom.
The compounds of the present invention, surprisingly, exhibit an outstanding tolerance in cotton crops which is not the case with known compounds of analogous constitution.
In addition, they have a very good action against weeds that are difficult to control, for example
Amaranthus, Stellaria, Matricaria and others, which can be controlled by both the pre-emergence and the post-emergence methods.
Application quantities within the range of from 1 to a maximum of 5 kg of active substance per hectare are generally sufficient to control these seed weeds, the compounds of the present invention exhibiting a selective action also in useful plant crops other than cotton, for example soya, ground-nut, potatoes, maize, rice, sorghum and cereals. When two or more compounds of the present invention are used, the range of 1 to 5 kg refers of course to the total application quantities of these compounds.
The present invention accordingly also provides a herbicidal preparation which comprises a compound of the general formula I, in admixture or conjunction with a suitable carrier. The preparation may of course contain one or more compounds of the general formula I.
The present invention further provides a method of protecting a living plant against weeds, wherein the area in the vicinity of the living plant is'treated with a compound of the general formula
The present invention further provides a method of protecting a crop area against weeds, wherein the crop area is treated with a compound of the general formula I.
The present invention further provides a pack which comprises a compound of the general formula i together with instructions for its use as a herbicide.
The compounds of the present invention may be used either singly or in the form of mixtures with one another or with other active substances. If desired, other piant-protecting agents and/or pesticides may be added, depending on the desired aim.
If a broadening of the range of action is intended, other herbicides may also be added. As suitable herbicidally active co-components there may be mentioned, for example, active substances from the groups of triazines, aminotriazoles, anilides, diazines, uracils, aliphatic carboxytic acids and halocarboxylic acids, substituted benzoic acids and aryloxycarboxylic acids, hydrazides, amides, nitrides, esters of such carboxylic acids, carbamic acid esters and thiocarbamic acid esters, ureas, 2,3,6trichlorobenzyloxyisopropanol and thiocyanogen-containing agents.
Furthermore, other additives may also be used, for example non-phytotoxic additives which with herbicides produce a synergistic increase in action, for example wetting agents, emulsifiers, solvents and oily additives.
The active compounds of the present invention or mixtures containing them are advantageously used in the form of herbicidal preparations, for example powders, strewable preparations, granules, solutions, emulsions or suspensions, with the addition of liquid and/or solid vehicles or diiuents and, if desired, of surface-active agents, for example wetting, adhesive, emulsifying and/or dispersing auxiliary agents.
Suitable liquid carriers are, for example, water, aliphatic hydrocarbons, aromatic hydrocarbons, for example benzene, toluene and xylene, cyclohexanone, isophorone, dimethyl sulphoxide and dimethylformamide, and also mineral oil fractions.
Suitable solid carriers are, for example, mineral earths, for example tonsil, silica gel, talcum, kaolin, attaciay, limestone and silicic acid, and vegetable products, for example meals.
As surface-active agents there may be mentioned, for example, calcium lignin sulphonate, polyoxyethylenealkylphenol ethers, naphthale nesulphonic acids and salts thereof, phenolsuiphonic acids and salts thereof, formaldehyde condensates, fatty alcohol sulphates and also substituted benzenesulphonic acids and salts thereof.
The proportion of the active substance or substances in the various herbicidal preparations may vary within wide limits. For example, the preparations may contain approximately 5 to 95% by weight of active substance(s), approximately 95 to 5% by weight of liquid or solid carrier and also, if desired, up to 20% by weight of surface-active agent(s).
The active compounds may be applied in the usual manner, for example with water as the carrier in spray liquor quantities of approximately 50 to 1000 litres/hectare. It is also possible to apply the active compounds by the so-called low-volume andultra-low-volume methods as well as to apply them in the form of so-called microgranules.
As groups represented by the symbol R1 in the general formula I there may be mentioned, for example, methyl, ethyl, propyl, isopropyl, butyl, isobutyl, sec.-butyl and 2-phenylethyl groups, and as groups represented by the symbol R2, for example, methyl, ethyl, propyl, isopropyl, butyl, isobutyl, sec.
butyl, allyl, propargyl, chlorethyl, 1 -chloromethylethyl, 4-chlorobutynyl, 1 -methylpropynyl and 4chlorobutenyl groups.
Compounds of the present invention which are distinguished by an outstanding selective herbicidal action are especially N-ethyl-3-fiuorocarbanilic acid (3-ethoxycarbonylaminophenyl) ester,
N-ethyl-3-fluorocarbanilic acid (3-methoxycarbonylaminophenyl) ester, N-ethyl-3-fluorocarbanilic acid [3-( 1 -methylethoxycarbonylamino)-phenyl] ester, N-ethyl-4-fluorocarbanilic acid (3-ethoxycarbonyl- aminophenyl) ester, 4-fluoro-N-methylcarbanilic acid (3-ethoxycarbonylaminophenyl) ester, N-ethyl-3fluorocarbanilic acid [3-(1 -methylethoxycarbonylamino)-phenyl] ester, N-ethyl-4-fluorocarbanilic acid [3-( 1 -methylethoxycarbonylamino)-phenyl] ester, 4-fluoro-N-methylca rba nilic acid [3-(1 1-methyl ethoxycarbonylamino)-phenyl] ester, 3-fluoro-N-methylcarbanilic acid [3-( 1 methylethoxycarbonyl- amino)-phenyl] ester, N-ethyl-3,4-difluorocarbanilic acid (3-ethoxycarbonylaminophenyl) ester and
N-ethyl-2-fluorocarbanilic acid (3-methoxycarbonylaminophenyl) ester.
The new compounds of the general formula I may be manufactured, for example, by the process of the present invention, as defined below.
The present invention accordingly further provides a process for the manufacture of the compounds of the general formula I, wherein
a) a compound of the general formuta
in which R2 and X have the meanings given above, is reacted with an amine of the general formula
in which iR, and Y have the meanings given above, in the presence of an acid acceptor, for example with the addition of an excess of the amine or of an inorganic base, for example a sodium hydroxide solution, sodium -carbonate or potassium carbonate, or a tertiary organic base, for example triethylamine, or
