One leaf of this cabbage was immersed in the test chemical solution for 60 seconds. After the cabbage leaf was air-dried, the cabbage leaf was placed in a 500 ml cup with filter paper. Ten second-instar larvae of Spodoptera litura were released into the cup. The life and death of the tested insects were observed after 2 days. The insecticidal rate was calculated by correcting the result according to the following equation. Note that the test was repeated three times. The results are shown in Table 2.
Death rate (%) = 100 × ((number of test insects−number of surviving insects) / number of test insects)

Sprinkle 200 ml of test chemicals per 3 pots on tangerines planted in No. 6 pot and let them air dry. 100 potted dwarf larvae are released from this potted mandarin orange.
On the other hand, a pot-planted mandarin orange in which 100 testicular larvae of red beetle were released without spraying a test chemical solution is defined as an untreated section.
Seven days after the treatment, the survival number of the tested insects is investigated in each of the treated group and the untreated group, and the control rate is obtained by the following formula. The test is repeated 3 times.
As a result of the test, the chemical solution for test shows a high control rate.
Control rate (%) = 100 × ((N0 × M1 / M0−N1) / (N0 × M1 / M0))
N0: Number of live insects in the treated area N1: Number of live insects in the treated area M0: Number of live insects in the untreated area M1: Number of live insects in the untreated area

Spreading agent (trade name: Shindyne (registered trademark), Sumitomo Chemical Co., Ltd.) in water containing 0.02% by volume, spinetoram (Spinetram J: Spinetoram L = 75: 25 (weight ratio)) 11.7% by weight A flowable formulation containing selenium is added so that the concentration of spinetoram is 50 ppm, and a granule wettable powder containing 20.0% by weight of pyrifluquinazone (trade name: Colt (registered trademark) granule wettable powder, Nippon Agricultural Chemicals Co., Ltd.) is added to pyrifluquinazone. Add the solution so that the concentration becomes 50 ppm and mix well to prepare a test chemical.
Strawberries are planted in an 860 ml pot, infested with tobacco whitefly, and grown to the 8th leaf stage. The potted strawberry is sprayed with 100 ml of test chemical solution per 3 pots.
On the other hand, a pot-planted strawberry that has not been sprayed with the test chemical is defined as an untreated section.
Before the treatment and 7 days after the treatment, the number of larvae of tobacco whiteflies parasitic on the strawberry leaves is investigated in each of the treated group and the untreated group, and the control rate is obtained by the following formula. The test is repeated 3 times.
As a result of the test, the chemical solution for test shows a high control rate.
Control rate (%) = 100 × ((N0 × M1 / M0−N1) / (N0 × M1 / M0))
N0: Number of larvae in the treated group before treatment N1: Number of surviving larvae in the treated group after 7 days of treatment M0: Number of larvae in the untreated group before treatment M1: Number of viable larvae in the untreated group after 7 days of treatment

Test Example 8
Spreading agent (trade name: Shindyne (registered trademark), Sumitomo Chemical Co., Ltd.) 0.02% by volume of water contains spinetoram (Spinetram J: Spinetoram L = 75: 25 (weight ratio)) 25% by weight Add granule hydrated preparation to spinetoram concentration to 25ppm, and add granulant wettable powder (trade name: Colt (registered trademark) granule wettable powder, Nippon Agricultural Chemicals Co., Ltd.) containing 20.0% by weight of pyrifluquinazone. Add the solution so that the concentration becomes 50 ppm and mix well to prepare a test chemical.
100 apple hatched larvae are released from apples planted in No. 6 pot, and 500 ml of test chemical is sprayed per 3 pots.
On the other hand, a pot-planted apple that has not been sprayed with the test chemical is defined as an untreated section.
Ten days after the treatment, the number of surviving insects tested in each of the treated group and the untreated group is examined, and the control rate is obtained by the following formula. The test is repeated 3 times.
As a result of the test, the chemical solution for test shows a high control rate.
Control rate (%) = 100 × ((N0 × M1 / M0−N1) / (N0 × M1 / M0))
N0: Number of live insects in the treated area N1: Number of live insects in the treated area M0: Number of live insects in the untreated area M1: Number of live insects in the untreated area

Test Example 9
Spreading agent (trade name: Shindyne (registered trademark), Sumitomo Chemical Co., Ltd.) in water containing 0.02% by volume, spinetoram (Spinetram J: Spinetoram L = 75: 25 (weight ratio)) 11.7% by weight A flowable preparation containing selenium is added so that the concentration of spinetoram is 50 ppm, and a granule wettable powder (trade name: Colt (registered trademark) granule wettable powder, Kumiai Chemical Industry Co., Ltd.) containing 20.0% by weight of pyrifluquinazone is added. Add the pyrifluquinazone to a concentration of 25 ppm and mix well to prepare the test drug solution.
Cabbage is planted in a pot with a capacity of 860 ml and grown until the 4th leaf stage. Cut the cabbage leaves one by one. One piece of this cabbage leaf is immersed in the test chemical for 60 seconds. After the cabbage leaf is air-dried, the cabbage leaf is put into a 500 ml cup with filter paper. Ten third instar larvae are released into the cup (this is referred to as the treatment section).
On the other hand, one cabbage leaf is not immersed in the test chemical and air-dried, but put into a 500 ml cup with filter paper. Ten third instar larvae are released in the cup, and this is designated as an untreated section. After 4 days, the treated insects are observed for life and death in each of the treated group and the untreated group, and the death rate is determined by the following formula.
Death rate (%) = 100 x (number of dead insects / number of test insects)
The result is corrected by the following formula to calculate the insecticidal rate. The test is repeated 3 times.
As a result of the test, the test chemical solution shows a high insecticidal rate.
Insecticide rate (%) = 100 × (Mt−Mc) / (100−Mc)
Mt: Death rate in treated area (%)
Mc: Death rate in untreated area (%)
