The present invention relates to a novel triazine derivative or its salt, and herbicides containing it as an effective component.
Triazine derivatives are known from “Collection of Czechoslovak Chemical Communications (1969), 34(6), 1673-83,” etc., for example. However, no herbicidal activity is described for the compounds disclosed in these literatures. Although various compounds are reported as triazine-based herbicides (for example, see “The Pesticide Manual 15th Edition, 2009, published by BCPC”), they all have a 1,3,5-triazine ring. Specific examples of the 1,3,5-triazine-based agrochemicals include 2-chloro-4,6-bis-(ethylamino)-1,3,5-triazine (Simazine), 2-chloro-4-ethylamino-6-isopropylamino-1,3,5-triazine (Atrazin), 2,4-bis(ethylamino)-6-meltylthio-1,3,5-triazine (Simetryn), 2,4-bis(isopropylamino)-6-methylthio-1,3,5-triazine (Prometryn), and 2-(1,2-dimethylpropylamino)-4-ethylamino-6-methylthio-1,3,5-triazine (Dimethametryn). Further, as a 1,2,4-triazine-based agrochemical, there are known 4-amino-3-methyl-6-phenyl-1,2,4-triazine-5(4H)-one (Metamitron), 4-amino-6-tert-butyl-3-methylthio-1,2,4-triazine-5(4H)-one (Metribuzin), etc. It is disclosed in Japanese Patent Application Laid-Open (JP-A) No. 8-259546 that 4-(2,4-dihalogeno-5-alkoxyphenyl)-1,2,4-triazine-3,5-dione derivatives having a hydrocarbon substituent group at 6-position have a herbicidal activity. It is disclosed in JP-A No. 5-51369 that 3,5-diaryl-6-amino-1,2,4-triazine derivatives have a herbicidal activity. It is disclosed in JP-A No. 5-32641 that 3-mercapto-1,2,4-triazine derivatives have a herbicidal activity.
However, it is not known from any literatures that 6-acyl-1,2,4-triazine-3,5-dione derivatives represented by Formula 1 below have a herbicidal activity.
Herbicides used for useful crops and useful plants are required to be a chemical preparation which can be applied to soils or leaves and exhibit a sufficient herbicidal effect with low chemical dosage. Further, as there is an increasing need concerning safety and effect on environment of a chemical substance, development of safer herbicides is waited for. The invention is devised to cope with such problems.
In order to achieve the object above, inventors of the invention synthesized many triazine compounds to study the herbicidal activity of various triazine derivatives, and intensively determined the herbicidal activity and usefulness of the compounds. As a result, it is found that, when triazine derivatives of the invention are applied to weeds or soils wherein weeds thrive, an excellent herbicidal effect is obtained for a long period of time, and therefore the invention is completed accordingly.
Thus, the present invention relates to the following (1) to (43).

2.0 g (9.89 mmol) of diethyl 2-oxomalonate and 0.04 g (0.2 mmol) of p-toluene sulfonic acid were dissolved in 50 ml of toluene. To the solution, 2.5 g (15.2 mmol) of 1-methyl-N-phenylhydrazine carboxamides was added at room temperature, and then stirred for 2 hours with reflux under heating. The reaction mixture was cooled to room temperature and added with 0.08 g (0.5 mmol) of 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) followed by stirring at room temperature for two hours. The reaction solution was washed with water and dried over magnesium sulfate. The solvent was distilled off to obtain ethyl 2-methyl-3,5-dioxo-4-phenyl-2,3,4,5-tetrahydro-1,2,4-triazine-6-carboxylic acid ester.
Ethyl 2-methyl-3,5-dioxo-4-phenyl-2,3,4,5-tetrahydro-1,2,4-triazine-6-carboxylic acid ester produced from the above (1) was stirred for 24 hours at room temperature in a mixed solvent of acetic acid (30 ml) and conc. hydrochloric acid (30 ml). The reaction mixture was concentrated under reduced pressure, extracted with a saturated aqueous solution of sodium hydrogen carbonate, washed with ethyl acetate, and then adjusted to be weakly acidic by using diluted hydrochloric acid. After that, the mixture was extracted with ethyl acetate and dried over magnesium sulfate, and the solvent was distilled off to obtain 2.6 g of 2-methyl-3,5-dioxo-4-phenyl-2,3,4,5-tetrahydro-1,2,4-triazine-6-carboxylic acid as a white solid (2-step yield 70%).

10 parts of the compound (I-1), 0.5 parts of polyoxyethylene octylphenyl ether, 0.5 parts of sodium β-naphthalene sulfonate formalin condensate, 20 parts of diatomaceous earth, and 69 parts of clay were mixed and pulverized to give a wettable powder
20 parts of roughly crushed compound (I-1) were dispersed in 69 parts of water, and added with 200 ppm of silicone AF-118N (trade name, manufactured by Asahi Kasei Corporation) while simultaneously adding 4 parts of polyoxyethylene styryl phenyl ether sulfonate and 7 parts of ethylene glycol. After mixing for 30 minutes by high-speed mixer, the mixture was pulverized using a wet-type pulverizer to give a flowable agent.
30 parts of the compound (I-1), 60 parts of a mixture of xylene and isophorone (1:1 mixture), and 10 parts of a mixture of polyoxyethylene sorbitan alkylate, polyoxyethylene alkylaryl polymer, and alkylaryl sulfonate were mixed well to give an emulsifiable concentrate.
10 parts of the compound (I-1), 80 parts of extender in which talc and bentonite are mixed in ratio of 1 to 3, 5 parts of white carbon, and 5 parts of a mixture of polyoxyethylene sorbitan alkylate, polyoxyethylene alkylaryl polymer, and alkylaryl sulfonate were added with 10 parts of water. After kneading well, the resulting paste was extruded through a sieve (diameter; 0.7 mm) followed by drying. By cutting it to have length of 0.5 to 1 mm, granules were obtained.
Effect of the compounds of the invention is explained by way of following test examples.
Test for determining herbicidal activity by paddy field soil treatment
A 100 cm2 wide plastic pot was filled with a paddy field soil and, after watering and shuffling, seeds of each of Echinochloa oryzicola, Monochoria vaginalis, and Scirpus juncoides Rocxb. were sowed and watered to a depth of 3 cm. On the next day, the wettable powder obtained in view of Formulation example 1 was diluted with water and applied on water surface. The application amount was 1000 g of effective component per hectare. After that, the plants were cultivated in a greenhouse, and on day 21 after the treatment, evaluation was made by the criteria of Table 72 for determining the herbicidal effects. The results are shown in Table 73 to Table 76.

A 80 cm2 wide plastic pot was filled with a field soil and seeds of each of Echinochloa crus-galli, foxtail. Indian millet, and A. retroflexus were sowed and then covered with soil. The wettable powder produced with reference to the Formulation example 1 was diluted water, and applied on the soil surface by using a small sprayer in an amount of 1000 liters per hectare so that the effective component is 1000 g per hectare. After that, the plants were cultivated in a greenhouse, and on day 21 after the treatment, evaluation was made by the criteria described in Table 72 for determining the herbicidal effects. The results are shown in Table 77 to Table 80.

A 80 cm2 wide plastic pot was filled with a field soil and seeds of each of Indian millet and A. retroflexus were sowed and then incubated for 2 weeks in a green house. The wettable powder produced with reference to the Formulation example 1 was diluted water, and applied from the air to entire body of the plant as foliage treatment by using a small sprayer in an amount of 1000 liters per hectare so that the effective component is 1000 g per hectare. After that, the plants were cultivated in a greenhouse, and on day 14 after the treatment, evaluation was made by the criteria described in Table 72 for determining the herbicidal effects. The results are shown in Table 81 to Table 84.
