Strawberry Anthracnose (Glomerella cingulata) causes severe loses in strawberry nurseries throughout Japan, despite the use of recommended fungicide. This study was carried out to evaluate the activity of two rice blast granule chemicals on the disease. In the nursery bed, probenazole at 9g a. i./m² and pyroquilon at 4g a. i./m² controlled the disease by row application. In raising seedlings in pots (9cm in diameter, 300ml in capacity), only probenazole at 5g per pot adequately controlled the disease. Probenazole was the most active material against strawberry anthracnose in nursery bed and raising seedlings in pots.
