Abstract

Technical Field
[0001] This application belongs to the field of insecticides, specifically relating to a m-diamide compound, its preparation method, and its application. Background Technology
[0002] In crop production in agriculture, forestry, and horticulture, damage caused by pests remains significant. Due to pest resistance to existing pesticides and their environmental unfriendliness, there is still a need to develop new pesticides, especially highly effective, low-toxicity, and environmentally friendly ones.

[0382] Example 29: Inhibitory activity test of m-phenylenediamine compounds containing a diamide structure against diamondback moth.
[0383] The bioactivity of the compound against the diamondback moth was determined using the leaf-dipping method. 0.1000 g each of the compound from the examples and the commercial insecticide chlorantraniliprole were accurately weighed using an electronic balance, dissolved in acetone, and diluted to a final volume of 10 mL in a volumetric flask to prepare 10000 mg / L stock solutions. Based on preliminary experiments, four series of concentrations were set for each agent according to the content of the active ingredient: 100, 10, 1, and 0.1 mg / L. According to the above dosage settings, the 35 compounds and the positive control group (commercial chlorantraniliprole) were diluted to the designed concentrations with an aqueous solution containing 0.1% Tween 80, with each concentration consisting of 100 mL of solution. A 0.1% Tween 80 aqueous solution without the agent was used as a blank control. Each tested agent was diluted to the four set concentrations for later use. Immerse cabbage leaves in the test solution for 15 seconds, then remove and air dry before placing them in disposable plastic boxes. Inoculate each box with 15 healthy, uniform third-instar larvae of the diamondback moth. Each treatment is repeated four times. The treated insects are then reared in an artificial climate chamber with a temperature of (27±0.5)℃, relative humidity of (70±10)%, and a photoperiod L:D = 14h:10h. After 48 hours, record the number of live and dead diamondback moths. Insects that do not move when gently touched with a brush are considered dead. The activity test results are shown in Table 1-1.
[0384] Table 1-1 Insecticidal activity of compounds I-3 to I-28 against diamondback moth
[0385]
[0386] As shown in Table 1-1, most of the compounds in the examples showed superior insecticidal activity against diamondback moth. Some compounds even showed better insecticidal activity than the commercial insecticide chlorantraniliprole. For example, compounds I-9 and I-25 showed excellent insecticidal activity, with compound I-9 exhibiting the best insecticidal activity.
[0387] The data above show that the novel diamide insecticide prepared in this application has high insecticidal activity, and some compounds are more effective than the commercial insecticide chlorantraniliprole.
