数））×１００ Test Example 5 Rice seedlings grown in the same manner as in Test Example 1 were used. Three hours before transplantation, 30 to 50 g of each of orizemate granules (commercial preparation containing probenazole 8%, Meiji Seika Co., Ltd.) and the preparation obtained in Preparation Example 4 were applied to a nursery box, and watering was performed immediately thereafter. 3
After an hour, the seedlings were scraped off with a rice transplanter, five seedlings per strain were selected, and two seedlings were planted in a 1 / 5000a Wagner pot. 1
One repetition was performed with 10 pots per section. Five pots were spray-inoculated with a rice blast spore suspension 30 days later, and the remaining five pots were spray-inoculated with a spore suspension 49 days later, and 9 days after each inoculation, the number of lesions formed on leaf blades was investigated. did. The control value was calculated from the average number of lesions per leaf by the following formula. The results are shown in Tables 5 and 6, respectively. Control value = (1− (average number of lesions in treated section / average number of lesions in untreated section)) × 100
