The blast disease rate in FIG. 6 shows that the initial disease was early and the survey was delayed in the current year.
The disease increased due to transmission from other rice fields other than seed transmission, but the number of cases tended to be lower than in the fir plot (all of the current normal cultivation uses this fir seeding). In particular, the untreated area of unpolished rice was transplanted next to the fir plot, so the transmission from the fir plot increased the incidence of disease. FIG.
In the case of CMC-talc, the disease-causing strain was observed in the case of the tobacco seedling disease, but it was smaller than that in the fir plot, and was zero in the other plots, indicating that the disease control effect was high. Further, from FIG. 7, the growth state is the same in each section, and no inhibition by the coating is observed.

Test Example 4 The effect of suppressing the onset of blast and the state of growth in submerged direct sowing cultivation were examined. Brown rice seeds (variety Kinuhikari) that had been subjected to each coating treatment were air-dried, and were directly soaked with water by hand on a field where water had been dropped immediately before sowing on May 19, and after sowing, water was added. On July 6 and 7, the blast disease-causing strain rate, the number of lesions per strain, the establishment rate of seedlings, and the growth state (plant height, number of stems) were examined. The results are shown in FIGS. The seedling establishment rate and the number of lesions per plant are shown as ratios to the control fir seeding plot. Further, PT indicates a water-soluble polyacrylic resin and talc, PK indicates a water-soluble polyacrylic resin and activated carbon, and CT indicates a seed coated with a CMC aqueous solution and talc.

From the results shown in FIG. 8, it can be seen that the seedling establishment rate is equal to or higher than that of the fir plot in the brown rice-coated seed sowing plot, and the incidence of blast is remarkably low. Further, from the results shown in FIG. 9, the growth state is almost the same in each section, and particularly in the case of the activated carbon film, the growth state tends to be slightly improved. These results indicate that the coated seeds are sufficiently applicable to the flooded direct sowing method.

From the results shown in FIGS. 10 and 11, the brown rice-coated seeds with black activated carbon showed a remarkable improvement in the rate of emergence and establishment of seedlings in the seedlings in the field and in the seeds directly immersed in the seeds, as compared with the normal seeding. A promoting effect was observed. That is, in FIG. 10, emergence of the coated seeds in the field state starts earlier than four days as compared with fir sowing, and the seedling establishment rate reaches 70% or more earlier than one week. In the flooded state of FIG. 11 (direct sowing conditions in flooded soil), the difference was further increased. The germination rate 12 days after sowing was 56% to 80% for the coated seeds and 38% for the firs.
