Embodiment 1
[0064] (1) Preparation of spray liquid
[0065] Prepared using: 500 g / L 3-chloro-N-(3-chloro-5-trifluoromethyl-2-pyridyl)-α,α,α-trifluoro-2,6-dinitropara Toluidine (fluazinamine (common name), Frowncide SC (trade name), manufactured by Ishihara Sangyo Kaisha, Ltd.) so that the amount of the active ingredient was 250 g ai / 10a (500 mL product / 10a), and the amount of dilution water was 150L / 10a.
[0066] (2) Disease control experiment of Chinese cabbage
[0067] Spray the spray liquid prepared above on the cultivation soil in the field, so that the spraying amount is 0.25g / m 2 (150L / 10a), thereafter, spread the agricultural mulch on the soil. After the planting holes (diameter: about 5 cm) for fixing were made, Chinese cabbage seedlings (cultivar variety: Musou (Musou)) grown for 4 weeks in a plug tray (128 holes / nursery box) were planted, so that in a 6m 2 30 seedlings with three replicates were planted in the experimental plot of the same area.
Embodiment 2
[0087] (1) Preparation of spray liquid
[0088] Prepared using: 500 g / L 3-chloro-N-(3-chloro-5-trifluoromethyl-2-pyridyl)-α,α,α-trifluoro-2,6-dinitropara Toluidine (fluazinam, FrowncideSC (trade name), manufactured by Ishihara Sangyo Kaisha, Ltd.) made the amount of the active ingredient 250 g ai / 10a (500 mL product / 10a), and the amount of dilution water 150 L / 10a.
[0089] (2) Disease control experiment of Chinese cabbage
[0090] Spread the agricultural mulch film on the soil, and make a fixed planting hole (diameter: about 5cm), and then spray the spray liquid prepared above on the planting hole so that the spraying amount is 0.25g / m 2 (150L / 10a), then air dry. Then, Chinese cabbage seedlings (cultivar: Yumebuki) grown for 4 weeks in plug trays (128 holes / seedling box) were planted so as to grow in a 4.8 m 2 34 to 40 seedlings with three replicates were planted in the experimental plot of the same area.

Embodiment 3
[0096] (1) Preparation of spray liquid
[0097]Prepared using: 500 g / L 3-chloro-N-(3-chloro-5-trifluoromethyl-2-pyridyl)-α,α,α-trifluoro-2,6-dinitropara Toluidine (fluazinam, FrowncideSC (trade name), manufactured by Ishihara Sangyo Kaisha, Ltd.) so that the amount of the active ingredient is 62.5g ai / 10a (125mL product / 10a), 125g ai / 10a (250mL product / 10a) and 250g ai / 10a (500mL product / 10a), the amount of each dilution water is 150L / 10a.
[0098] (2) Disease control experiment of Chinese cabbage
[0099] Spread the agricultural mulch film on the soil, and make a fixed planting hole (diameter: about 9cm), then, spray the above-mentioned prepared spraying liquid on the planting hole, so that the amount of the active ingredient processed contains 62.5g in the spraying liquid 0.0625g / m in case of ai / 10a active ingredient 2 (150L / 10a), 0.125g / m where the spray liquid contains 125g ai / 10a active ingredient 2 (150L / 10a), 0.25g / m where the spray liquid contains 250g ai / 10a activ...
