200-250 larvae of sweet potato root nematode stage 2 larvae were immersed in a drug adjusted to a predetermined concentration, and kept in a constant temperature room at 25 ° C for 24 hours. Under the microscope, the total number of sweet potato root nematodes (A) in the drug, and the number (B) which did not move for 15 seconds in the drug were examined. In addition, the control population using distilled water instead of the chemical liquid was also examined for the total population A 'and the population B' that did not move for 15 seconds. From these values, the inhibition rate of motion was determined by the following equation. The results are shown in Tables 2 to 13.

% Of motion inhibition = [1-{(1-B / A) / (1-B '/ A')}] × 100

In addition, the theoretical value (%) of the exercise inhibition rate was calculated by Colby's formula.

After 8 cm filter paper was immersed in a powder suspension and air-dried, 3 sheets of 8 cm shaale were overlaid and 2 ml of drug of organophosphorus compound and / or fungicide of predetermined concentration was added. Fifty adult females of Shaledan root mite were inoculated and capped, and allowed to stand in a constant temperature room at 25 ° C. After 48 to 72 hours, observation was carried out under a stereoscopic microscope, and death and death were determined to determine mortality.

Insect mortality (%) = {1- number of surviving birds / insects)} × 100

In addition, the theoretical value (%) of a mortality rate can be calculated by Colby's formula. When the experimental value (%) of the mortality rate is higher than the theoretical value (%), the harmful biological control composition of this invention has a synergistic effect with respect to the control of the harmful organism of a root mite.

Ten larvae were released immediately after the scarab was hatched, and left in the dark at 25 ° C. for 5 to 10 days in the dark. After dismantling the soil, the number of surviving larvae was counted.

Insect mortality (%) = {1- (number of survival / insect insects)} × 100

In addition, the theoretical value (%) of a mortality rate can be calculated by Colby's formula. When the mortality rate (%) is higher than the theoretical value (%), the pest control composition of the present invention has a synergistic effect on the control of pests of scarabs.

The medium containing the was cut out and implanted in the medium containing a drug. After 4 to 7 days incubation in a 25 ℃ constant temperature room, the mycelial elongation inhibition rate was determined by measuring the elongated mycelial length.

Mycelial elongation inhibition rate (%) = {1- (mycelial elongation of the pharmaceutical treatment / no mycelial elongation)} × 100

In addition, the theoretical value (%) of the mycelial elongation inhibition rate can be calculated by Colby's formula. When the mycelial elongation inhibition rate (%) is higher than the theoretical value (%), the harmful biological control composition of the present invention has a synergistic effect with respect to the control of pests.

Immediately after addition of the drug, 20 days and 40 days later, 500 cc of sweet potato rootworm nematode (Meloidogyne incognita) contaminated soil was inoculated into each pot, and after being sufficiently mixed, tomato seedlings (cultivar: strong rice seedlings) were transplanted. The degree of root gall engraftment (0 to 100% engraftment) of the nematodes was examined 51 days after transplantation, and the results are shown in Table 13. In addition, in order to unify the transplantation day, the mixture of sandy loam and the drug was reversed from the transplantation day. In addition, the theoretical value (%) of root nodule engraftment was calculated by Colby's formula When the root nodule engraftment percentage (%) was lower than the theoretical value (%), the harmful biological control composition of the present invention was prepared by The theoretical value (%) in such a case was also shown in () of Table 13 together.

Test Example 6

After 66 days from sowing, the incidence of gall bladder disease was examined, and the stem between the second and third sections of cucumbers was cut, and the degree of browning of the catheter was evaluated by five steps based on the following criteria. The index was calculated. These results are shown in Table 15. In addition, the test was performed by the triple flame retardant. In addition, the theoretical values of the incidence rate and the damage index were calculated by Colby's formula. When the incidence rate and the damage index are lower than the theoretical value, the harmful biological control composition of the present invention has a synergistic effect on the control of cucumber manure disease. The theoretical value (%) in such a case was shown together in () of Table 15.

A: All state

B: at least two-thirds of the conduit turns brown

C: about half of the conduit is browned

D: Less than 1/3 of the conduit browns

E: no browning of conduit

N: number of weeks surveyed (7 for this test)
