[0015]
Next, it is shown by test examples that the composition of the present invention exhibits excellent insecticidal and acaricidal effects.
In general, the insecticidal rate expected when two kinds of active ingredients given are mixed and processed can be obtained by the Colby equation of the following formula 1.
[Expression 1]
E = X + Y− (X × Y / 100)
X: insecticidal rate when active compound A is treated with Mppm (%)
Y: Insecticidal rate when active compound B is treated with Nppm (%)
E: Insecticidal rate (%) expected when active ingredient compound A is treated with Mppm and active ingredient compound B is treated with Nppm (hereinafter referred to as a theoretical value).
[0016]
Test Example 1 [Insecticidal test for Plutella xylostella (strain resistant to organophosphates, carbamates, etc.)]
To the diluted solution of the test composition obtained in accordance with Formulation Example 1 with water, a spreading agent (New Reno: manufactured by Nippon Agricultural Chemicals Co., Ltd.) was added at a 3000-fold dilution, and the cabbage grown in the pot (No. 1) For 4 to 5 leaf stages), 25 ml was sprayed per pot. After the treated plants were air-dried, 20 third instar larvae were released and the mortality was determined after 5 days. The mortality was corrected by Equation 2 to calculate the insecticidal rate.
[Expression 2]
Insecticide rate (%) = 100 × (Mt−Mc) / (100−Mc)
Mt: Mortality rate (%) of test compound treatment
Mc: Mortality (%) of the test compound-untreated group
The results are shown in Table 1.
