Description

DETAILED EXPLANATION OF THE INVENTION

The present invention concerns carbamate derivatives, process for the preparation of such compounds, and herbicides comprising the same as an active ingredient.

Hitherto, it has been well-known that arylthiocarbamate derivatives have antifungal activity as drugs and also that aryl N-arylcarbamate derivatives can be used as herbicides.

The present inventors found and reported earlier that some N-pyridylcarbamate derivatives have herbicidal activity. Furthermore, the present invention was completed by earnestly conducted investigation to develop N-pyridylcarbamate and N-pyrimidylcarbamate derivatives which exhibited sufficient herbicidal activity and high selectivity.

More especially, the present invention provides carbamate derivatives represented by the general formula (I) (hereinafter referred to as the compounds of the present invention): ##STR2## wherein X is 2-naphthyl, 5-indanyl, 5,6,7,8-tetrahydro-2-naphthyl, 1,4-methano-1,2,3,4-tetrahydro-6-naphthyl, 1,4-ethano-1,2,3,4-tetrahydro-6-naphthyl, 2-quinolyl, or substituted phenyl having one or more than one of the same or different substituents selected from the group of halogeno, lower alkyl, lower alkenyl, lower alkoxy, lower alkenyloxy, lower alkynyloxy, lower alkylthio, lower alkylamino, (hydroxy-lower alkyl, (lower alkoxy-lower alkyl, acyl, nitro, cyano, methylenedioxy, and halogenated lower alkyl,

Y is an oxygen atom or a sulfur atom, Z is lower alkyl, W is pyridyl substituted by one or two of the same substituents selected from the group of halogeno, lower alkyl, and lower alkylamino when X is 2-naphthyl but W is pyridyl or pyrimidyl which is unsubstituted or substituted by one or two of the same or different substituents selected from the group of halogeno, nitro, lower alkyl, lower alkoxy, lower alkylthio, and lower alkylamino when X is other than 2-naphthyl, process for the preparation of such compounds, and herbicides containing the same as an active ingredient.

The herbicides containing the compounds of the present invention show extremely excellent herbicidal activity against barnyard grass as well as many general weeds in the flooded paddy field, and they are substantially harmless against transplanted rice plants. Therefore, these herbicides are suitable for use in the paddy field. In addition, the herbicides containing the compounds of the present invention were recognized to have an applicability to be used in the farmland from the observation that they showed excellent herbicidal selectivity between gramineous weeds and broadleaved crops in the soil treatment of the farmland.

The carbamate derivatives of the present invention represented by the general formula (I) can be prepared according to the following reaction equations (1) and (2): ##STR3## wherein X is 2-naphthyl, 5-indanyl, 5,6,7,8-tetrahydro-2-naphthyl, 1,4-methano-1,2,3,4-tetrahydro-6-naphthyl, 1,4-ethano-1,2,3,4-tetrahydro-6-naphthyl, 2-quinolyl, or substituted phenyl having one or more than one of the same or different substituents selected from the group of halogeno, lower alkyl, lower alkenyl, lower alkoxy, lower alkenyloxy, lower alkynyloxy, lower alkylthio, lower alkylamino, hydroxy, -lower alkyl, lower alkoxy, -lower alkyl, acyl, nitro, cyano, methylenedioxy, and halogenated lower alkyl,

Y is an oxygen atom or a sulfur atom, Z is lower alkyl, W is pyridyl substituted by one or two of the same substituents selected from the group of halogeno, lower alkyl, and lower alkylamino when X is 2-naphthyl but W is pyridyl or pyrimidyl which is unsubstituted or substituted by one or two of the same or different substituents selected from the group of halogeno, nitro, lower alkyl, lower alkoxy, lower alkylthio, and lower alkylamino when X is other than 2-naphthyl, Hal is a halogen atom.

The above-stated reactions proceed in the presence of dehydrohalogenation agents and further in the presence or absence of reaction solvents usually at the reaction temperature ranging from 0.degree. to 150.degree. C. during the reaction time ranging from about few minutes to 48 hours.

As the dehydrohalogenation agents, alkali hydroxides such as sodium hydroxide, potassium hydroxide and the like; alkali earth hydroxides such as calcium hydroxide and the like; alkali carbonates such as sodium carbonate, potassium carbonate, sodium bicarbonate, potassium bicarbonate and the like; metal hydrides such as sodium hydride and the like; and tertiary amines such as triethylamine, N,N-dimethylaniline, pyridine and the like can be exemplified. The starting amine derivatives can be used as the dehydrohalogenation agents in the reaction shown by the equation (2).

As the reaction solvents, water; alcohols such as methanol, ethanol, isopropanol and the like; ketones such as acetone, methyl ethyl ketone and the like; aromatic hydrocarbons such as benzene, toluene, xylene, and the like; ethers such as ethyl ether, tetrahydrofuran, dioxane and the like; halogenated hydrocarbons such as chlorobenzene; chloroform, carbon tetrachloride, dichloroethane and the like; and polar solvents such as dimethylformamide, dimethylsulfoxide and the like can be used.

In order to use compounds of the present invention as herbicides, proper amount of one or more than one of the compounds represented by the above-stated general formula (I) is incorporated with inert carriers to use as usual agricultural chemicals like water dispersible powder, emulsifiable concentrate, granules, dust and so on.

As solid carriers, talc, clay, diatomaceous earth, bentonite, kaolin, Japanese acid clay, white carbon, pumice powder and the like are exemplified. As liquid carriers, water, alcohol, benzene, toluene, xylene, kerosine, cyclohexane, cyclohexanone, isophorone, Butyl Cellosolve, benzyl acetate, dimethylformamide, mineral oil and the like are used.

Furthermore, surface-active agents and stabilizers can be added when they are required. In addition, the herbicides of the present invention can be applied after incorporating them with other agricultural chemicals used in the same field, for example, insecticides, fungicides, herbicides, plant growth regulators or fertilizers. Especially, there will be occasions for the herbicides containing the compounds of the present invention that it is proper to be mixed with other herbicides for the purpose of reducing labor for spreading or for the purpose of extending the spectrum of weed species to be effectively prevented.

As herbicides to be added, triazine herbicides such as Atrazine, Simazine, Simetryn, Prometryn and the like; carbamate herbicides such as Asulam, Benthiocarb, Molinate and the like; urea herbicides such as Linuron, Dymrone and the like; phenoxy-series herbicides such as 2,4-D, MCP, MCPB, Naproanilide and the like; diphenyl ether herbicides such as Nitrofen, Chlornitrofen, Chlomethoxynil and the like; heterocyclic-series herbicides such as Oxadiazon, Pyrazolate, Bentazon and the like; and amide herbicides such as Alachlor, Butachlor, Propanil and the like can be exemplified. It is possible to provide mixtures of the compounds of the present invention by being skillfully combined with one or more than one of the herbicides described above to be effective to many weed species.

Examples of the formulation in which the compounds of the present invention were used are explained herein-below. In the Examples, the term "parts" means parts by weight.

EXAMPLE 5

Water dispersible powder

A mixture of the compound No. 14 of the present invention (10 parts), Zeeklite (Trade Name, manufactured by Kunimine Kogyo Co., Ltd., 87.3 parts) used as the carrier material, Neopelex (Trade Name, manufactured by Kao Atlas Co., Ltd., 1.35 parts), and Solpol 800A (Trade Name, manufactured by Toho Kogyo Co., Ltd., 1.35 parts) was pulverized to give 10% water dispersible powder.

EXAMPLE 6

Emulsifiable concentrate

A mixture of the compound No. 15 of the present invention (25 parts) and Solpol 800A (10 parts) was dissolved in 65 parts of benzene to give 25% emulsifiable concentrate.

EXAMPLE 7

Granules

A mixture of the compound No. 24 of the present invention (10 parts), 50 parts of bentonite, 35 parts of Kunilite (Trade Name, manufactured by Kokuho Kogyo Co., Ltd.) and 5 parts of Solpol 800A used as the surface-active agent was pulverized. After 10 parts of water was added, the mixture was kneaded to give a homogeneous mixture and then the mixture was extruded through sieving perforations having a diameter of 0.7 mm and dried. The product was cut off to give 10% granules having length of 1-2 mm.

The compounds of the present invention are suitable for an active ingredient of herbicides since the herbicides containing these compounds do not show any phytotoxity against many useful crops like rice, soybean, cotton and the like but have excellent herbicidal activity against various weeds. More particularly, as to the herbicidal action of the compounds of the present invention, characteristic features are that the compounds kill weeds, or inhibit the growth, or suppress the growth considerably to result in a failure of growth competition against crops.

Application amount of the compounds of the present invention is generally in the range of 10 to 1000 g/10 ares, preferably 50 to 500 g/10 ares as an active ingredient although it differs depending upon the place applied, the application time, the application methods, and weeds to be avoided.

The compounds of the present invention were found to have outstanding herbicidal activity against barnyard grass as well as many weeds such as umbrella plant, monochoria, tooth cup, bulrush and so on in the use of 50-500 g/10 ares as an active ingredient, especially under submerged paddy field condition. In addition, the compounds of the present invention are highly safe to young seedling of rice plants and no affection has been observed even in the application amount of 1000 g/10 ares as an active ingredient. Therefore, the compounds of the present invention have extremely excellent characteristics as an active ingredient of herbicides to be used for paddy field. Furthermore, the application period can be considerably extended since some of the compounds of the present invention have good herbicidal activity against barnyard grass even in a growth period (1- to 3-leaf stage). That is to say, it was shown that these compounds have high applicability as an active ingredient of soil-applied herbicides in a cultivation of transplanted rice plants at the primary to medium stage and immediately after flooding in a cultivation of dry-seeded rice.

Surprisingly, it was also shown that the herbicides containing some of the compounds of the present invention have high applicability to be used in farmland because those herbicides, when they are used as soil-applied agents after the seeding of general broadleaved crops like soybean, effectively prevent gramineous weeds such as barnyard grass, crab grass, and foxtail without any phytotoxity to crops.

The herbicidal effects of the compounds of the present invention are explained in the below-stated Examples.

EXAMPLE 8

Test for the herbicidal effects under submerged conditions (I)

Paddy field soil was charged in porcelain pots having a diameter of 9 cm, and then water was added. After the soil was tilled, weed seeds were sown on the surface of the soil and two bunches of rice plants (variety: Nihonbare) being in 2-leaf stage were transplanted in 1 cm depth. The pots were flooded to give water depth of 2 cm on the next day and predetermined amount of water dispersible powder of the compounds of the present invention, which was dispersed in 10 ml of water, was added dropwise into every pots on the surface of water for the treatment. Then they were settled in a greenhouse and received water in proper time intervals. After 3 weeks from the treatment with chemicals, the herbicidal effects as well as the influences against the rice plants were examined.

EXAMPLE 9

Test for the herbicidal effects under submerged conditions (2)

Paddy field soil was charged in porcelain pots having a diameter of 9 cm, and then water was added. After the soil was tilled, seeds of barnyard grass were sown on the surface of the soil and two bunches of rice plants (variety: Nihonbare) being in 2-leaf stage were transplanted in 1 cm depth. The pots were flooded to give water depth of 2 cm on the next day and predetermined amount of water dispersible powder of the compounds of the present invention, which was dispersed in 10 ml of water, was added dropwise into every pots on the surface of water for the treatment before the germination of and at the time of both 1.2- and 2-leaf stages of barnyard grass. The pots were settled in a greenhouse and received water in proper time intervals. The examination was carried out after 3 weeks from the treatment with the chemicals and the results were evaluated in the similar manner as in Example 8. The results are shown in Table 3.
