Description

TECHNICAL FIELD

The present invention relates to novel 4,5-disubstituted pyrimidine derivatives and herbicides containing such derivatives as active ingredients.

BACKGROUND TECHNIQUE

The group of compounds of the present invention which contain a pyrimidine ring having hydrogen atoms at the 2- and 6- positions and having specific substituents introduced at the 4- and 5- positions, is a group of novel compounds and, heretofore, their herbicidal activities have not been known.

In order to protect important crop plants such as rice, soybean, wheat, corn, cotton and sugar beet from weeds and to increase their productivities, many herbicides have been put into practical use. These herbicides can roughly be classified into three categories, i.e. those for upland fields, for paddy fields, and for non-agricultural fields, according to the application site. Further, each category can be classified into, for example, a soil incorporation treatment type, a pre-emergence soil treatment type and a post-emergence treatment (foliage treatment) type, according to the manner of application.

With the recent global population increase, the productivities of important crop plants will undoubtedly affect the food economy of each country. With such changes, the conventional mode of agriculture will be inevitably changed toward the 21st century. Actually, it has been increasingly required than ever for persons engaged in agriculture to develop herbicides which can economically and effectively kill or control weeds detrimental to the growth of crop plants.

As such herbicides, chemicals which meet the following requirements are desired to be developed.

Preferred are those having high herbicidal effects at low doses (it is necessary to kill weeds at as low doses as possible from the viewpoint of environmental protection), those having adequate residual activities (since a problem that soil-persistent chemicals damage next crops has arisen recently, it is important to show an adequate residual activity after application), those which promptly kill weeds upon application (it is possible to sow or transplant next crops soon after chemical treatment), those which do not require frequent treatment (it is important for farmers to minimize the frequency of cumbersome weed control operations), those intended to control a wide range of weeds (chemicals capable of controlling a variety of weeds having different properties such as broad-leaves weeds, graminaceous weeds and perennial weeds, are desirable), those which can be applied by various methods (a stronger herbicidal effect can be obtained by combining an effect of soil treatment, an effect of foliage treatment and so on), and those which do not show any problematic phytotoxicity against crop plants (in a field where a crop plant coexists with weeds, those capable of selectively killing weeds are desired). However, no existing herbicides satisfy all of these requirements.

When the compound of the present invention is used as a herbicide, it is usually mixed with a suitable carrier, for instance, a solid carrier such as clay, talc, bentonite, diatomaceous earth or white carbon, or a liquid carrier such as water, an alcohol (such as isopropanol, butanol, benzyl alcohol or furfuryl alcohol), an aromatic hydrocarbon (such as toluene or xylene), an ether (such as anisole), a ketone (such as cyclohexanone or isophorone), an ester (such as butyl acetate), an acid amide (such as N-methylpyrrolidone) or a hologenated hydrocabron (such as chlorobenzene). If desired, a surfactant, an emulsifier, a dispersing agent, a penetrating agent, a spreader, a thickner, an antifreezing agent, an anticaking agent, or a stabilizer may be added to prepare an optional formulation such as a liquid formulation, an emulsifiable concentrate, a wettable powder, a dry flowable, a flowable, a dust or a granule.

Further, the compound of the present invention may be combined with other herbicides, various insecticides, miticides, nematicides, fungicides, plant growth regulators, synergists, fertilizers, antidotes, or soil conditioning materials at the time of the preparation of the formulations or at the time of the application, as the case requires.

Particularly, combined use of the compound of the present invention with another agricultural chemical can be expected to result in lower cost attributable to reduction in the dose, a broader spectrum and a higher herbicidal effect attributable to synergistic action of the combined chemicals. In such a case, the compound of the present invention can be combined with plural known agricultural chemicals simultaneously. The agricultural chemicals which may be used in combination with the compound of the present invention, may, for example, be compounds disclosed in Farm Chemicals Bandbook (1994).

The dose of the compound of the present invention varies depending upon the application site, the season for application, the manner of application, the type of crop plants and the like. However, it is usually within a range of from 0.00001 to 10 kg, preferably from 0.0001 to 5 kg per hectar (ha) as the amount of the active ingredient.
