[0086]
The "Efficacy" in each test means a value calculated by the following "Equation 1", and it is ranked depending 20 on its numerical value as shown in Table 5.
"Equation 1"
Efficacy = 100 x (X - Y)/X
where X: Degree of fungal growth in non-treated area 25 Y: Degree of fungal growth in treated area PC7V..1132014/069266 [0087]
[Table 5]
Efficacy Efficacy Rank more than 95 A
80 or more to less than 95 50 or more to less than 80 30 or more to less than 50 less than 30 [0088]
Test Example 1: Control Test against wheat leaf blotch (Septoria tritici) Each of the testing compounds was diluted with dimethyl sulfoxide (DMSO) to the prescribed concentration, respectively, and each DMSO solution of the testing compounds was dispensed into a titer plate (with 96 wells) in the amount of 1 pl. Thereto was then dispensed 150 pl of a potato dextrose broth to which conidia of wheat leaf blight fungus were inoculated in advance. This plate was cultured at 18 C for four days, thereby allowing wheat leaf blight fungus to undergo proliferation, and the absorbance at 550 nm of each well of the titer plate was then measured to determine a degree of growth of the wheat leaf blight fungus. The efficacy was calculated from the obtained degree of growth by the above-mentioned "Equation 1", and was then ranked according to [Table 5]. The test results are shown in the following Table 6 to Table 16.
