Embodiment 1

[0023] Embodiment 1: Preparation of tertiary amine derivative formula (I)

[0024] 1.1 Synthesis of 4-iodo-2-trifluoromethylphenol

[0025]

[0026] 2-Trifluoromethylphenol (10 mmol) was dissolved in 20 ml of dichloromethane, 2 ml of DMF was added thereto, stirred for 10 minutes, then N-iodosuccinimide (12 mmol) was added thereto, the system temperature Rise to about 80°C, react for 2 hours, cool down to room temperature, filter to remove insoluble matter, wash the remaining solution twice with 2% dilute hydrochloric acid aqueous solution, dry the organic phase with anhydrous sodium sulfate, filter, and crystallize from the natural volatile solvent , 2.5 g of off-white 4-iodo-2-trifluoromethylphenol crystals were obtained with a yield of 87%. 1 H-NMR (400 MHz, CDCl 3 ) δ: 5.09(s, 1H), 6.48(d, 1H), 7.81(m, 2H). 13 C-NMR (75 MHz, CDCl 3 ) δ: 84.79, 119.05, 124.47, 132.07, 141.65, 158.07. LC-MS (ESI, pos, ion) m / z: 289 [M+H].

Embodiment 2-8

[0036] Embodiment 2-8: Insecticidal composition suspension

[0037] Each component of the insecticidal composition suspending agent is by weight, and the composition ratio is as follows:

[0038]

[0039] The components under the various examples in the above table were mixed, dispersed at high speed for 30 minutes, and sanded with a sand mill to prepare the insecticidal composition suspension.

Embodiment 9

[0040] Embodiment 9: Insecticidal composition wettable powder

[0041] Weigh 10% tertiary amine derivative formula (I), 40% spirotetramat, 4% GY-D06, 3% alkylnaphthalene sulfonate formaldehyde condensate (diffusion agent NNO), 1.5% dodecyl sulfate Sodium, 5% clay sodium sulfate, and kaolin are added to 100% by weight. After the above raw materials are uniformly mixed, the 50% wettable powder of the insecticidal composition is prepared through the step of ultrafine airflow pulverization.

Abstract

The invention discloses an insecticidal composition containing a tertiary amine derivative formula (I) and spirotetramat, components of different preparation types of the insecticidal composition anda preparation method. Through a co-toxicity test and a field insecticidal test, it is found that a good prevention and control effect is achieved on plant pests through mixed matching and use of the tertiary amine derivative formula (I) and spirotetramat, the significant synergistic effect is achieved, the pesticide application cost can be reduced, and the problem that the plant pests are difficult to prevent and control is effectively solved.

Description

technical field [0001] The invention relates to an insecticidal composition, which is composed of the first active ingredient tertiary amine derivative formula (I) and the second active ingredient spirotetramat, and belongs to the technical field of compound pesticides. Background technique [0002] The mechanism of action of spirotetramat is the same as that of spirofen, spirofen and spirotetramat, all of which are lipid biosynthesis inhibitors (lipid biosynthesis inhibitor, LBI). Spirotetronic acid compounds inhibit the activity of acetyl-CoA carboxylase (ACCase) in the process of fat synthesis in pests, destroy lipid synthesis, block the normal energy metabolism of pests, and eventually lead to their death. [0003] Spirotetramat is highly effective and long-lasting, and has excellent control effect on piercing-sucking mouthparts pests, and provides inhibition to some harmful mites. Mainly control aphids (including cotton aphid, cabbage aphid, peach aphid, grape phylloxe...
