A predetermined amount of tricyclazole, flutolanil, pencyclon and compound (I) is added to a surfactant (polyoxyethylene sorbitan monococoate, trade name: Sorgen TW-20, manufactured by Daiichi Kogyo Seiyaku Co., Ltd.) at 5% (w / v). Water containing 0.02% by volume of a spreading agent (trade name: Dyne (registered trademark), manufactured by Sumitomo Chemical Gardening) so as to have a predetermined concentration after dissolving in 0.2 ml of acetone (manufactured by Wako Pure Chemical Industries) Diluted with
A water solution of the present pyridine compound, a water solution of tricyclazole, and a water solution of flutolanil, pencyclon, or compound (I) were mixed at a predetermined concentration to prepare a test drug solution.
Use a spray gun to cultivate rice (Oryza sativa, cultivar: Nanatsuboshi) with seedlings grown for about a month after seeding in a plastic pot containing culture soil and the sixth true leaf fully developed. 10 ml per 1 pot was sprayed. After air-drying, cultivate in PDA medium for 3 days, inoculate rice strains with about 1 cm ^{2 of} blight fungus that has spread on a 9 cm petri dish, and in a 28 ° C wet room (humidity 95-100%) Cultivated for 7 days, and the height of the lesion (the height of the lesion in the treatment area) was measured. The test was repeated twice.
Rice was cultivated in the same manner as described above except that the test chemical solution was not sprayed, and the lesion height was measured (the lesion height in the untreated area). The control value was calculated by the following formula 3).

Formula 3); Control value = 100 × (A−B) / A
A: Height of lesions in the untreated group B: Height of lesions in the treated group Table 9 shows the average values.

Test Example 6
Acetone (manufactured by Wako Pure Chemical Industries, Ltd.) containing 3 mg of this pyridine compound and 5% (w / v) of a surfactant (polyoxyethylene sorbitan monococoate, trade name: Sorgen TW-20, manufactured by Daiichi Kogyo Seiyaku) After dissolving in 0.2 ml, the solution was diluted with water containing 0.02% by volume of a spreading agent (trade name: Dyne (registered trademark), manufactured by Sumitomo Chemical Horticulture) to a predetermined concentration. A predetermined amount of tricyclazole, flutolanil, pencyclon and compound (I) is added to a surfactant (polyoxyethylene sorbitan monococoate, trade name: Sorgen TW-20, manufactured by Daiichi Kogyo Seiyaku Co., Ltd.) at 5% (w / v). Water containing 0.02% by volume of a spreading agent (trade name: Dyne (registered trademark), manufactured by Sumitomo Chemical Gardening) so as to have a predetermined concentration after dissolving in 0.2 ml of acetone (manufactured by Wako Pure Chemical Industries) Diluted with
A water solution of the present pyridine compound, a water solution of tricyclazole, and a water solution of flutolanil, pencyclon, or compound (I) were mixed at a predetermined concentration to prepare a test drug solution.
After seeding in a plastic pot containing culture soil, rice seedlings grown for two weeks and the second true leaf fully developed (Oryza sativa, variety: Nanatsuboshi) using the spray gun 10 ml was sprayed per pot. After air drying, it was allowed to stand in a wet room (humidity 95-100%) at 25 ° C. for 24 hours together with rice that developed blast. Then, after isolating the rice that developed the rice blast, the rice was cultivated in the moist chamber for 5 days, and the lesion area ratio (referred to as the lesion area ratio in the treated area) was measured. The test was repeated twice.
Rice was cultivated in the same manner as described above except that the test chemical solution was not sprayed, and the lesion area ratio (the lesion area ratio in the untreated area) was measured. The control value was calculated by the following formula 4).

Formula 4); Control value = 100 × (A−B) / A
A: The lesion area ratio of an untreated section B: The lesion area ratio of a treated section The average value is shown in Table 10.
