The above compounds are particularly industrially easily produced and have excellent herbicidal activity.
The cyanoketone derivative of the formula (1), provided by the present invention, can be structurally identified by measurements of infrared absorption spectrum (IR), mass spectrum (MS) and .sup.1 H-nuclear magnetic resonance spectrum (.sup.1 H-NMR) and elemental analysis. Typical patterns thereof are as follows.
(i) In the measurement of the cyanoketone derivative of the formula (1) for infrared absorption spectrum (IR), a characteristic absorption based on the ether bond is observed at 1,180 to 1,230 cm.sup.-1, and a characteristic absorption based on the cyano group is observed at 2,210 to 2,220 cm.sup.-1.
(ii) The cyanoketone derivative of the formula (1) is measured for mass spectrum (MS), and its composition formula corresponding to each peak observed (generally, a value of m/e obtained by dividing an ion molecular weight, m, by a number of charge, e) is calculated, whereby the molecular weight of the cyanoketone compound and the bonding mode of each atomic group in the molecule can be determined. That is, when a sample measured has the formula (1), there are generally observed molecular ion peaks (to be abbreviated as "M.sup.+ " hereinafter) having strength according to an isotopic abundance depending upon the number of halogen atoms contained in the molecule, and the molecular weight of the sample therefore can be determined. Further, the molecular weight generally appears as a mass number of each ion derived from the sample which has been cleaved in positions indicated by dotted lines in the following formula (7) ##STR9## wherin A.sub.1, X.sub.1, X.sub.2, X.sub.3, Y.sub.1, Y.sub.2, Y.sub.3, Y.sub.4, B.sub.1, B.sub.2, B.sub.3 and A.sub.2 are as defined above.
(iii) The bonding mode of hydrogen bonds in the compound of the present invention, represented by the above formula (1), can be determined by measurement of the compound for .sup.1 H-nuclear magnetic resonance spectrum (.sup.1 H-NMR). That is, in the measurement of the compound of the formula (1) in a heavy chloroform solvent, a peak of methine substituted with a cyano group often appears at 5.50 to 5.70 ppm as a multiplet since the carbon atom to which the cyano group is bonded is an assymmetric carbon, and protons on the phenyl group show a multiplet at 6.70 to 7.50 ppm.
(iv) The weight of each of carbon, hydrogen and nitrogen (and halogen if contained) is determined by elemental analysis, and then by deducting the total sum of recognized weight percentages of these elements from 100, the weight percentage of oxygen can be determined. Accordingly, the composition formula of the compound can be determined.

A study of the present inventors has showed that the novel cyanoketone derivative of the formula (1), provided by the present invention, has herbicidal activity.
According to the present invention, therefore, there is also provided a herbicide containing the cyanoketone derivative of the formula (1) as an effective or active component.
The form for use of the herbicide of the present invention is not specially limited, and can be selected from known forms. For example, it can be used in the form of any one of granules, a dust, an emulsifiable concentrate, a wettable powder, a flowable agent, a tablet, an aerosol and a fuming agent, which are prepared by using an inert solid carrier, a liquid carrier or an emulsification dispersant in combination.
Further, In the preparation of the formulation, there may be incorporated an auxiliary agent such as a wetting agent, a diluent and a surfactant. The herbicide of the present invention can be used in the form of a liquid or a solid to which the above auxiliary agent is properly incorporated. A surfactant is often effective for improvement in the dispersibility of the herbicide in water or an oil.
The above surfactant can be selected from known anionic surfactants, cationic surfactants and nonionic surfactants used for the preparation of general herbicides. Examples of the particularly suitable surfactants include alkylbenzenesulfonic acid, alkylnaphthalenesulfonic acid, fatty acid sulfonate, polyoxyethylene alkylphenyl ether sulfonate, sodium alkylsulfate, sodium lignin sulfonate and polyalkylnaphthalene sulfonate.
Typical examples of the form of the cyanoketone derivative of the formula (1) for use as a herbicide are as follows.
A wettable powder and granules generally contain an inert solid carrier and a surfactant in addition to the active component of the formula (1). The inert solid carrier is generally selected from natural or synthetic inorganic powders. The most preferred are, for example, clays, talc, potassium carbonate, diatomaceous earth and silica. The wettable powder and granules generally contain 1 to 80 parts by weight of the active component, 5 to 98 parts by weight of the inert solid carrier and 1 to 15 parts by weight of the surfactant. Polyvinyl alcohol and sodium carboxymethylcellulose may naturally be incorporated as required.
The emulsifiable concentrate is generally prepared by dissolving the active component and the surfactant in a solvent. The solvent is preferably selected from those which can dissolve the active component. Typical examples of the solvent include xylene, phenoxyethanol, cyclohexane, solvent naphtha, methylnaphthalene and kerosene. The emulsifiable concentrate generally contains 75 to 20 parts by weight of the active component, 10 to 20 parts by weight of the surfactant and 15 to 60 parts by weight of the solvent.
The dust is a product in which the active component is held on a natural or synthetic inorganic powder. The dust is generally prepared by mixing 0.5 to 6 parts by weight of the active component and 99.5 to 94 parts by weight of the inorganic powder.
The flowable agent is a suspension product prepared by suspending the active component insoluble in water, and adding a dispersant to disperse the suspended active component in water. It is the most widely employed embodiment to suspend 20 to 50% by weight of the active component.
The fuming agent is prepared by incorporating a heat generating agent and a heat generation adjuster. The heat generating agent is selected from nitrates, nitrites, guanidine salts and potassium chlorate. The heat generation adjuster is selected from alkali metal salts and potassium nitrates.
The novel cyanoketone derivative of the formula (1) has remakably high herbicidal activity and is effective against a variety of gramineous weeds. Examples of the weeds against which the herbicidal activity is generally effective include upland soil gramineous weeds such as fall panicum, green foxtail, sorghum, wild oat, Japanese brome, water foxtail, annual bluegrass, barnyardgrass, Johnsongrass, quackgrass, southern crabgrass, goosegrass, Italian ryegrass, burmudagrass and knotgrass.
The cyanoketone derivative of the formula (1) is a novel compound which has high selectively, i.e., remarkably high herbicidal activity against gramineous weeds and safety for broad-leaved crops. Therefore, it has characteristic features in that it is completely harmless to crops such as soybean, adzuki bean, peanut, sunflower, cotton, etc., even when it is used in a high dosage. When the compound of the formula (1), provided by the invention, is sprayed as a herbicide to gramineous plants, not only the use of it as a soil-applied herbicide is effective, but the use of it as a foliar-applied herbicide is also effective. Further, when the carbon atom to which the substituents B.sub.1 and B.sub.2 are bonded is an asymmetric carbon, R-enantiomer works particularly effectively.
In general, the suitable dosage as an active component of the herbicide of the present invention is in the range of 0.05 to 20.0 kg/h, preferably 0.10 to 6.0 kg/h.

The present invention will be explained further in detail hereinafter by reference to Examples. The present invention, however, shall not be limited to these Examples.

EXAMPLE 10
Herbicidal effect by foliar application
Upland farm soil (clay loom) was filled in 1/8,850-are pots, and seeds of barnyardgrass, green foxtail, blue morningglory, slender amaranth and hairy beggarticks were sown 0.5 to 1 cm deep. When these weeds grown to two- or three-leaf stage, a wetting agent was added to solutions prepared by diluting wettable powders of the compounds with water, and a predetermined amount of each of the mixtures was sprayed to the foliage. After the application, the weeds were allowed to grow in a greenhouse at an average temperature of 25.degree. C. for 2 weeks, and then the herbicidal effects of compounds tested were examined. In addition to compounds of the present invention, the comparative compound of the following formula (14) was also used. ##STR207##

EXAMPLE 11
Test on phytotoxicity on crops by foliar application
Upland farm soil (clay loom) was filled in 1/8850-are pots, and seeds of soybean, adzuki bean and beet were sown 1.5 to 2 cm deep. When the soybean grown to a primary leaf development stage, the predetermined amount of each of the solutions prepared by diluting each of wettable powders of the compounds with water was sprayed to the foliage. After this application, these crops were allowed to grow in a greenhouse at an average temperature of 25.degree. C. for 2 weeks, and then the phytotoxicity of each of the test compounds on the crops was examined. The results are shown in Tables 33 to 39.
The herbicide injury was evaluated as follows. The ratios of the height and total weight (air-dried weight) of an applied lot to those of an unapplied lot were calculated. The lowest ratios of these factors were taken as 5, and the phytotoxicity was evaluated on the basis of the following six ratings 0 to 5.
0 . . . ratio to unapplied lot 100%
1 . . . ratio to unapplied lot 90-99%
2 . . . ratio to unapplied lot 80-89%
3 . . . ratio to unapplied lot 60-79%

EXAMPLE 12
Test on herbicidal effect by upland farm soil application
Upland farm soil (clay loom) was filled in 1/8,850-are pots, and seeds of barnyardgrass, green foxtail, slender amaranth and hairy beggarticks were sown 0.5 to 1 cm deep. Then, the predetermined amount of each of the solutions prepared by diluting the wettable powders of the compounds with water was sprayed to the soil. After the application, the weeds were allowed to grow in a greenhouse at an average temperature of 25.degree. C. for 2 weeks, and then the herbicidal effects of the test compounds were examined in the same manner as the above Example 10. The results are shown in Tables 40 to 48.
