Condensed heterocyclic derivatives and herbicides

Abstract

A condensed heterocyclic derivative of the formula (I): ##STR1## (wherein R is a hydroxyl group, R.sup.3 or R.sup.4 is an alkoxy group, W is an oxygen atom, Yn is a hydrogen atom, Z is a methine group, and A is a 5- or 6-membered heterocyclic ring which may be substituted, and a herbicide, are presented. When used for paddy field treatment, upland soil treatment and foliage treatment, the condensed heterocyclic derivative of the present invention exhibits excellent herbicidal activities against gramineous and non-gramineous weeds without adversely affecting crop plants.

Description

TECHNICAL FIELD

The present invention relates to condensed heterocyclic derivatives and their salts as well as herbicides containing them as active ingredients, which can be applied to paddy fields, upland fields and non-agricultural fields.

BACKGROUND ART

The present inventors found that quinoline and naphthalene derivatives have herbicidal activities and disclosed specific examples in Japanese Unexamined Patent Publication No. 56469/1990. Further, Japanese Unexamined Patent Publication No. 121973/1990 discloses that aromatic carboxylic acid derivatives containing quinoline, naphthalene, benzofuran, thiophene or pyridine ring have herbicidal activities.

However, the above-mentioned publications disclose nothing about specific compounds relating to the condensed heterocyclic derivatives of the present invention. Further, these compounds are not necessarily satisfactory from the viewpoint of the herbicidal effects. A number of other herbicides have been developed and contributed to the saving of energy for agricultural operations and to the improvement of the productivity. However, in their practical use, such herbicides also have various problems with respect to the herbicidal effects and the safety to crop plants.

The present inventors have conducted an extensive research on condensed heterocyclic derivatives with an object to develop a compound which is excellent in the herbicidal activities without bringing about phytotoxicity to crop plants. As a result, it has been found that the compounds of the present invention which are pyrimidine or triazine derivatives bonded to a condensed heterocyclic ring exhibit excellent herbicidal activities against not only annual weeds but also perennial gramineous weeds, cyperaceous weeds and broad leaf weeds in the paddy field treatment, upland soil treatment and foliage treatment, and they are highly safe to crop plants. The present invention has been accomplished on the basis of this discovery.

Compounds (I) of the present invention can be produced, for example, in accordance with the following processes 1 to 6. ##STR496## (wherein L.sup.1 is a halogen atom, an alkylsulfonyl group, a benzylsulfonyl group or a substituted benzylsulfonyl group, and R, R.sup.3, R.sup.4, A, W, Y, Z and n are as defined above.)

A compound of the formula (I) can be produced by reacting a compound of the formula (II) with a compound of the formula (III) in a suitable solvent in the presence of an at least equal amount of a base at a temperature within a range of from room temperature to the boiling point of the solvent for from 0.5 to 24 hours.

As the base, an alkali metal such as metal sodium or metal potassium, an alkali metal hydride or an alkaline earth metal hydride such as sodium hydride, potassium hydride or calcium hydride, an alkali metal alkoxide such as potassium t-butoxide, an alkali metal carbonate such as sodium carbonate or potassium carbonate, an alkali metal hydrogen carbonate such as sodium hydrogen carbonate or potassium hydrogen carbonate, or an alkali metal hydroxide such as sodium hydroxide or potassium hydroxide, may be used.

As the solvent, a hydrocarbon solvent such as benzene, toluene or xylene, a halogenated hydrocarbon solvent such as dichloromethane or chloroform, an ether solvent such as diethyl ether, tetrahydrofuran or 1,4-dioxane, an ester solvent such as methyl acetate or ethyl acetate, a ketone solvent such as acetone or methyl ethyl ketone, an aprotic polar solvent such as N,N-dimethylformamide, N,N-dimethylacetamide or dimethylsulfoxide, or acetonitrile, may, for example, be used.

The condensed heterocyclic carbonyl derivative (II) as the starting material can be obtained by known methods, for example, the methods disclosed in Bulletin de la Saciete Chimique de France), p. 2763-2766 (1975), J. Indian. Chem. Soc. Vol 45 (5), p. 439-445 (1968), Indian. J. Chem. Section B, 25B (8), p. 870-871 (1986), J. Chem. Soc. Organic Chemistry (1), p. 1-4 (1969), Indian. J. Chem.

The adjuvant may, for example, be carboxymethyl cellulose, polyethylene glycol or gum arabic.

In practical use, the herbicide may be diluted to a suitable concentration before application, or may be directly applied.

The herbicide of the present invention may be used for application to foliage, soil or water surface. The blending proportion of the active ingredient is suitably selected as the case requires. However, in a case of a dust or a granule, the proportion of the active ingredient is selected suitably within a range of from 0.01 to 10% by weight, preferably from 0.05 to 5% by weight. In a case of an emulsifiable concentrate or a wettable powder, the proportion is selected suitably within a range of from 1 to 50% by weight, preferably from 5 to 20% by weight.

The dose of the herbicide of the present invention varies depending upon the type of the compound, the weeds to be controlled, the germination tendency, the environmental conditions and the type of the formulation to be used. However, in the case of a dust or a granule which is used by itself, the dose of the active ingredient is selected suitably within a range of from 0.1 g to 5 kg, preferably from 1 g to 1 kg, per 10 ares. In a case of an emulsifiable concentrate or a wettable powder which is used in a liquid state, the dose of the active ingredient is selected suitably within a range of from 1 to 50,000 ppm, preferably from 10 to 10,000 ppm.

Further, the compound of the present invention may be used in combination with an insecticide, a fungicide, other herbicide, a plant growth controlling agent, a fertilizer or the like, as the case requires.

TEST EXAMPLE 4 (Test on Crop Plant Selectivity by Paddy Field Soil Treatment)

In a 1/10,000a plastic pot, paddy field soil was filled, irrigated, paddled and leveled. Then, barnyardgrass (Eo), monochoria (Mo) and bulrush (Sc) were sown at a depth of 0.5 cm. Further, two seedlings of rice (Or) of 2.5 leaf stage was transplanted at a transplantation depth of 2 cm. Then, the pot was flooded to a water depth of 3 cm. Next day, a prescribed amount of the active ingredient (g.sup.ai /10a) of a wettable powder prepared in accordance with Formulation Example 1 was diluted with water and applied dropwise to the water surface.
