[Table 1]

[0061] Test example 1

 200-250 larvae of the second stage larvae of Scutellaria perfringens were immersed in a drug solution adjusted to a predetermined concentration and kept in a constant temperature room at 25 ° C for 24 hours. Under a microscope, the total number of the sweet potatoes in the drug solution (A) and the number of individuals that did not move for 15 seconds in the drug solution (B) were examined. In addition, the total number of individuals (Α ') and the number of individuals who did not move for 15 seconds (Β') were also examined for the control group using distilled water instead of the drug solution. From these values, the exercise inhibition rate was determined by the following equation. The results are shown in Table 1 and Table 12.

 Exercise inhibition rate (%) = [1— {(1—Β / Α) Ζ (1—Β '/ Α')}] X 100

The theoretical value (Q / o) of the motor inhibition rate was calculated by Colby's formula. If motion inhibition rate _(0/0) is higher than the theoretical value (%), pest control composition of the present invention has a synergistic effect related to the control of nematodes. The theoretical values (%) in these cases are also shown in parentheses in Tables 1 and 12.

[0074] Test example 2

 Add water to the onion powder at a ratio of 1:10 and mix well. 8cm filter paper is immersed in a powder suspension and air-dried. Then, three pieces of 8cm petri dish are piled up and packed, and 2ml of a predetermined concentration of organic phosphorus compound and / or fungicide solution is removed. Inoculate 50 adult female spider mite per petri dish, cover, and allow to stand in a constant temperature room at 25 ° C. After 48 to 72 hours, observe under a stereoscopic microscope and determine the alive or dead to determine the mortality.

 Mortality (%) = {1- (number of surviving animals / number of released insects)} X 100

 The theoretical value (%) of the mortality can be calculated by Colby's formula. When the experimental value (%) of the mortality is higher than the theoretical value (%), the pest control composition of the present invention has a synergistic effect with respect to the control of pests of mite.

 In the range of organophosphorus compound: fungicide = 1: 100-100: 1, the experimental value of the mortality is higher than the theoretical value.

[0075] Test example 3

 Loam 3: Sand 1: Corrosive soil 1: A test soil is prepared, 200 g of soil is put into a 300 ml plastic container, and an organic phosphorus compound and / or a fungicide are added and mixed at a predetermined concentration. Immediately after the hatch beetle hatch, release 10 larvae and leave them in a constant temperature room at 25 ° C under black for 5-10 days. Then dismantle the soil and count the number of surviving larvae to obtain the mortality.

Mortality (%) = {1- (number of surviving animals / number of released insects)} X 100 The theoretical value (%) of the mortality can be calculated by Colby's formula. When the mortality (%) is higher than the theoretical value (%), the pest control composition of the present invention has a synergistic effect with respect to pest control of scarab beetles.

 Organophosphorus compound: fungicide = 1: 1000-1: 6 The experimental value of the mortality is higher than the theoretical value.

Test Example 4

 A PSA medium adjusted to contain a predetermined concentration of an organophosphorus compound and / or a bactericide is poured into an 8 cm dish, and Rhizoctonia, Pythium and Fusarium grown on another medium are cultured in a medium containing hyphae with a 6 mm cork hole. Cut out and transfer to medium containing drug. After culturing in a constant temperature room at 25 ° C for 4 to 7 days, measure the length of the elongated hypha and determine the inhibition rate of hypha elongation.

 Hyphal elongation inhibition rate (%) = {1- (hyphal elongation in drug-treated area / hyphal elongation without treatment)} X 100

 Further, the theoretical value (%) of the hyphal elongation inhibition rate can be calculated by Colby's formula. When the mycelial elongation inhibition rate (%) is higher than the theoretical value (%), the pest control composition of the present invention has a synergistic effect on the control of diseased bacteria.

 Organophosphorus compound: fungicide = 1: 100-10000: 1 The experimental value of the hyphal elongation inhibition rate shows a higher value than the theoretical value.

 [0077] Test Example 5

Paddy soil 4: 3 litters of sandy loam mixed with sand 1 was placed in a l / 5000a pot, and an organic phosphorus compound and Z or a fungicide were added and mixed at a predetermined concentration. Immediately after, 20 days and 40 days after the addition of the drug, 500 cc of soil contaminated with the nematode, S. elegans (Meloidogyne incognita), was inoculated into each pot, and after sufficient mixing, tomato (variety: strong rice longevity) seedlings were transplanted. 51 days after the transplantation, the degree of cat vegetation of the nematodes (0-100%) was examined. The results are shown in Table 13. The mixing of the sandy loam soil and the chemicals, which should be performed on the same transplant date, was performed in advance on the date calculated backward from the transplant date. Further, the theoretical value (./.) Of the degree of cat vegetation was calculated by Colby's formula. When the degree of cat vegetation (%) is lower than the theoretical value (%), the pest control composition of the present invention has a synergistic effect on the control of nematodes. The theoretical value (%) in this case is Also shown in parentheses in the table.

[0078] [Table 14]

 Table 13 Cat vegetation (%)

[0079] Test example 6

 After mixing soil contaminated with Meloidogyne incognita and Fusarium oxysoprum with a predetermined amount of a drug in a l / 1000a polypot, the seeds of cucumber (cultivar: northward) are mixed. Grains were sown. 66 days after sowing, the incidence rate of the cucumber vine wilt disease was investigated, the stem between the second and third nodes of the cucumber was cut off, and the browning degree of the conduit was evaluated on a 5-point scale according to the following criteria. Based on this, the damage index was calculated. Table 14 shows these results. Note that the test was performed in a three-part system. The theoretical value of the disease rate and damage index was calculated using Colby's formula. When the disease-causing strain rate and the damage index are lower than the theoretical values, the pest control composition of the present invention has a synergistic effect with respect to control of cucumber vine. The theoretical values (%) in such cases are also shown in parentheses in Table 14.

A: The whole plant dies

 B: More than 2/3 of the conduit is browned

C: About 1/2 of the conduit is browned D: Less than 1/3 of the conduit is browned

 E: No browning of conduit

 N: Number of surveyed strains (7 in this test)

 Damage index = {(4A + 3B + 2C + 1D) / 4N} * 100

 (2) After the operation of (1), a predetermined amount of nematrine ace granule (active ingredient I-a) was mixed into the soil, and four days later, seven seeds of cucumber (cultivar: Hokushin) were sown.

 (3) After 61 days of seeding power, the incidence rate of the cucumber vine wilt disease was investigated, and the damage index was calculated in the same manner as in Test Example 6. In addition, the level of nematode on the root of the cat (0 100%) was also examined. Table 15 shows the results. The test was performed in a triple system.

 For comparison, in the case where the operation of (1) was not performed, the prescribed amount of nematrine ace granule (active ingredient I-a) was applied to contaminated soil in (2), and after the operation of (1), The same test was carried out in the operation (2) in which a predetermined amount of nematrines granule (active ingredient I-a) was not mixed with the soil.
