     Production Process M 
     The compound [2] as the starting compound for the production of the present compound can be produced by reacting an isothiocyanate derivative of the general formula: 
     
         Q-NCS                                                      (19) 
    
     wherein Q is as defined above, with an amine derivative of the general formula: 
     
         R.sub.1 -NH.sub.2                                          (20) 
    
     wherein R 1  is as defined above, or by reacting an aniline derivative of the general formula: 
     
         Q-NH.sub.2                                                 (21) 
    
     wherein Q is as defined above, with an isothiocyanate compound of the general formula: 
     
         R.sub.1 -NCS                                               (22) 
    
     wherein R 1  is as defined above. 
     These reactions are usually effected in a solvent. The reaction temperature is usually in the range of 0° to 200° C., and the reaction time is usually a moment to 48 hours. The compound [20] or [21 ] is usually used at an amount of 1 to 3 moles per mole of the compound [19] or [22], respectively.

     Reference Example 1 ##STR24## 
     First, 38 g of the compound a-1 obtained by the process as described in Japanese Patent Laid-open Publication No. 54-19965 was dissolved in 250 ml of sulfuric acid, to which 9.0 g of fuming nitric acid was added dropwise while ice cooling. After 2 hours, the reaction mixture was poured into ice water, which was then extracted with ethyl acetate. The organic layer was washed with water, neutralized with potassium carbonate, and dried with magnesium sulfate, followed by hydrogenation with 5% Pd-C catalyst. After completion of the reaction, the catalyst was removed by filtration, and the organic layer was concentrated. The residue thus obtained was subjected to silica gel chromatography (eluent; hexane: ethyl acetate=2:1), which afforded 31 g of the compound a-2. 
     Then, 20 g of the compound a-2 was dissolved in 300 ml of toluene, to which 9.3 g of thiophosgene was added, and the mixture was heated under reflux for 2 hours, followed by removal of toluene by evaporation. The residue thus obtained was dissolved in 200 ml of chloroform, to which 8.0 g of methylamine (40% methanol solution) was added, and the mixture was stirred at room temperature for 2 hours. After completion of the reaction, the reaction mixture was poured into water, which was then neutralized with diluted hydrochloric acid, washed with water, dried with magnesium sulfate, and concentrated. The residue thus obtained was subjected to silica gel chromatography (eluent; hexane: ethyl acetate=2:1), which afforded 19 g of the compound a-3.

     As a result, it was found that all the test compounds exhibited the highest herbicidal activity &#34;5&#34; to barnyardgrass and the lowest phytotoxicity &#34;0&#34; to rice. 
     Test Example 9: Soil treatment on upland field 
     Box-type plastic pots of 32×22 cm 2  in bottom area and 8 cm in depth were filled with soil, and the seeds of redroot pigweed (Amaranth. vs retrofiexus), common lambsquarters (Chenopodium album), black nightshade (Solanum nigrum), large crabgrass (Digitaria sanguinalis) and soybean (Glycine max) were sowed in the soil. Each of the test compounds 115 and 402 was formulated into an emulsifiable concentrate according to Formulation Example 2, which was then diluted with water. The dilution was uniformly sprayed over the soil surface in the pots with a sprayer at a volume of 775 liters per hectare. For this treatment, each of the test compounds was applied at an amount of 300 grams per hectare. After the spraying, the test plants were grown in a greenhouse for 28 days, and the herbicidal activity to redroot pigweed, common lamb-squarters, black nightshade and large crabgrass, and the phytotoxicity to soybean were examined. 
     As a result, it was found that all the test compounds exhibited the highest herbicidal activity &#34;5&#34; to redroot pigweed, common lambsquarters, black nightshade and large crabgrass, and the lowest phytotoxicity &#34;0&#34; to soybean. 
     Test Example 10: Foliar treatment on upland field 
     Cylindrical plastic pots of 24 cm in diameter and 21 cm in depth were filled with soil, and the seeds of ivyleaf morningglory (Ipomoea hederacea), tall morningglory (Ipomoea purpurea), velvetleaf (Abutilon theophrasti), soybean (Glycine max) and corn (Zea mays) were sowed in the soil. After growing outdoors, the plants at the 2 to 4 leaf stage were prepared. Then, each of the test compounds 104, 253 and 255 was formulated into an emulsifiable concentrate according to Formulation Example 2, which was then diluted with water containing a spreading agent. The dilution was uniformly sprayed over the foliage of the test plants with a sprayer at a volume of 600 liters per hectare. Also 23% emulsifiable concentrate (commercially available formulation) of fomesafen (trade name: Reflex) as a reference compound was diluted with water containing a spreading agent, and the dilution was uniformly sprayed over the foliage of the test plants with a sprayer at a volume of 600 liters per hectare. For this treatment, each of the test compounds including the reference compound was applied at an amount of 100 grams per hectare. After the spraying, the test plants were grown outdoors for 32 days, and the herbicidal activity to ivyleaf morningglory, tall morningglory and velvetleaf, and the phytotoxicity to soybean and corn were examined. 
     As a result, it was found that all the test compounds exhibited the highest herbicidal activity &#34;5&#34; to ivyleaf morningglory, tall morningglory and velvetleaf, and the lowest phytotoxicity &#34;0&#34; to soybean and corn: on the other hand, the reference compound, fomesafen, exhibited the lowest phytotoxicity &#34;0&#34; to soybean and corn but insufficient herbicidal activity &#34;3&#34; to ivyleaf morningglory and &#34;2&#34; to tall morningglory and velvetleaf.
