Test example 7 Controlling test on blast of rice (Pyricularia oryzae) (preventive effect)
Sandy loam was filled in plastic pots, and rice (var., Kinki No. 33) was sowed and cultivated for 20 days in a greenhouse to obtain rice seedlings. The emulsifiable concentrates of the test compounds obtained according to Formulation example 1 were each diluted with water to a prescribed concentration and foliar-applied onto the seedlings so that the spray liquor thoroughly adhered to the leaf surface. After the spraying, the seedlings were air-dried and inoculated by spraying the spore suspension of Pyricularia oryzae. After the inoculation, the seedlings were placed for 8 days in a greenhouse of 26 C which was brought to a highly humid condition only during the night. The controlling activity was then examined.
