Test Example 3: Control Effect of Damping-Off in Rice Seedlings
A Rhizoctonia culture, a Fusarium culture and a Pythium culture were separately cultivated at 25°C for seven days in a wheat bran medium, and after respectively grinding, the Rhizoctonia culture, the Fusarium culture and/or the Pythium culture were added to and mixed in with sterilized soil, at amounts of:
O.P/o of Rhizoctonia culture with respect to the weight of sterilized soil;
0.1% of Fusarium culture with respect to the weight of stenlized soil;
0.1% of Pythium culture with respect to the weight of sterilized soil;
0.1%) of Rhizoctonia culture and 0.1% of Fusarium culture with respect to the weight of sterilized soil; and
0.1% of Rhizoctonia culture and 0.1 % of Physium culture with respect to the weight of sterilized soil. The infected soils were thus obtained.
Subsequently, soils in rice seedling boxes were treated with the powder formulation prepared in Example 1 and Reference Example 1, and a commercially available seed fungicide (TACHIGAREN, trade name, a powder formulation containing hydroxyisoxazol made by Sankyo Agro Co., Ltd.) as a control chemical, respectively, at amounts of 3g and 6g per rice seedling box (580 mm length x 280 mm width x 14 mm depth), and well mixed. After filling the above-mentioned infected soils in the rice seedling box, 100 seeds of force sprouted rice seeds were sown, covered with the infected soils and grown on in a greenhouse. The existence of disease onset was examined for all the seedlings with the naked eye at 30 days after starting cultivation, and the disease onset seedling ratio was computed by the following Formula 3. Moreover, the existence or not of occurrences of phytotoxicity was also examined with the naked eye. Results are shown in Table 3.
Formula 3: Disease onset seedling ratio =
(number of diseased seedlings/ number of seeds sown) x 100

Test Example 4 Control Effect against Sclerotinia Stem Rot and Foot rot in Cabbage
Test soils were prepared by:
cultivating a Rhizoctonia culture at 25°C for seven days in a wheat bran medium, adding this at 0.1% by weight to soil, and mixing uniformly to provide the test soil for foot rot; and
cultivating Sclerotium on a potato dextrose agar medium, adding this at 0.1% by weight to soil, and mixing uniformly to provide the test soil for Sclerotinia stem rot.
Next, the infected soils were put in a concrete pot (5 m length x 2 m width x 60 cm depth), and the powder formulations prepared in Example 4 and Reference Example 6, and a commercial fungicide (NEBIJIN, trade name, a powder formulation containing flusulfamide made by Sankyo Agro Co., Ltd.) as a control chemical, were distributed, on the surface of the infected soils at 30 kg per 10 are, respectively, and then incorporated into the soils. After the chemical treatment, 100 seeds of cabbage seed (variety: KXNKEI No. 201) were sown, respectively, and these were grow on. The existence of disease onset was examined with the naked eye at 110 days after sowing, and disease onset plant ratio was computed by the following formula 4. Moreover, the existence or not of occurrences of phytotoxicity was also examined with the naked eye. Results are shown in Table 4.
Formula 4: Disease onset plant ratio =
(number of plants with disease onset / total number of plants examined) x 100
