Test Example 2 Rice blast control test (penetration and transfer effect) A plastic pot was filled with sandy loam, and rice (Kinki 33
No.) and cultivated in a greenhouse for 14 days. A reagent prepared as an emulsion according to Formulation Example 4 was diluted with water in a rice seedling, and a predetermined amount thereof was irrigated into soil. After irrigation, they were grown in a greenhouse for 7 days, and sprayed and inoculated with a spore suspension of the blast fungus. After the inoculation, the plants were placed at 28 ° C. in the dark and in a humid environment for 4 days, and the control effect was examined. Table 4 shows the results.
