Test Example 1
The present amide compound (No. 4) 10 mg and trifloxystrobin 1 mg were mixed, and thereto were added 150 microliters of slurry that was prepared by mixing 10 parts of Color Coat Red (manufactured by Becker Underwood Inc.: coloring agent), 10 parts of CF-CLEAR (manufactured by Becker Underwood Inc.: spreading agent) and an appropriate amount of water so as to give a total amount of 100 parts and the resulting mixture was then mixed thoroughly and 7.5 μL of the mixture was added to 1 g of wheat seeds and the resulting mixture was then agitated. After air drying, the treated wheat seeds were seeded into a 85 mL plastic cup in a ratio of about 10 grains per the cup.
At 12 days post the seeding, spores of Puccinia recondita were inoculated into the cups, and then the cups were placed under a dark and humid condition at 23° C. for 24 hours (hereinafter, referred to as a “treated group”). At 7 days post the inoculation, a ratio of the symptom area of the second leaves to the total area of the second leaves was observed.
On the other hand, the same seeding and inoculation was carried out using wheat seeds without the above-mentioned treatment (hereinafter, referred to as an “untreated group”), and at 7 days post the inoculation, a ratio of the symptom area of the second leaves to the total area of the second leaves was observed.
From the results of the observation of the treated group and the untreated group, a control effect in the treated group was calculated by the following equation 1). The two duplicate tests were performed.
Control value (%)=(1−(Ratio of Symptom area of the second leaves to Total area of the second leaves in Treated group)/(Ratio of Symptom area of the second leaves to Total area of the second leaves in Untreated group))×100 Equation 1):
The present amide compound (No. 5) 10 mg and azoxystrobin or trifloxystrobin 1 mg were mixed, and thereto were added 150 microliters of slurry that was prepared by mixing 10 parts of Color Coat Red (manufactured by Becker Underwood Inc.: coloring agent), 10 parts of CF-CLEAR (manufactured by Becker Underwood Inc.: binding agent) and an appropriate amount of water so as to give a total amount of 100 parts and the resulting mixture was then mixed thoroughly, and 37.5 μL of the mixture was added to 5 g of corn seeds and the resulting mixture was then agitated. After air drying, the treated corn seeds were seeded into a 300 mL plastic cup in a ratio of 5 grains per the cup, and then covered with soil which had been mixed with a wheat bran culture of Fusarium graminearum (hereinafter, referred to as a “treated group''). At 18 days post the seeding, the number of seeds which failed to germinate was observed.
On the other hand, the same seeding was carried out using corn seeds without the above-mentioned treatment (hereinafter, referred to as an “untreated group”), and at 18 days post the seeding, the number of seeds which failed to germinate was observed. From the results of the observation of the treated group and the untreated group, a control value was calculated by the following equation 2).
Control value (%)=(1−(Ratio of seeds failed to germinate to Total number of sown seeds in Treated group)/(Ratio of seeds failed to germinate to Total number of sown seeds in Untreated group))×100 Equation 2)
The present amide compound (No. 4) 10 mg and azoxystrobin, pyraclostrobin or the compound (II-R) 1 mg were mixed, and thereto were added 150 microliters of slurry that was prepared by mixing 10 parts of Color Coat Red (manufactured by Becker Underwood Inc.: coloring agent), 10 parts of CF-CLEAR (manufactured by Becker Underwood Inc.: binding agent) and an appropriate amount of water so as to give a total amount of 100 parts, and the resulting mixture was then mixed thoroughly, and 37.5 μL of the mixture was added to 5 g of corn seeds and the resulting mixture was then agitated.
