Embodiment 1

[0030] According to the formula of Example 1 in Table 1, first add d-limonene to the preparation kettle, then add spirodiclofen, stir for about 20 minutes to dissolve completely, add emulsifier and make up the solvent, continue to stir evenly for about 15 minutes to prepare 5% For the spirodiclofen emulsifiable concentrate preparation, the content of each component in the formula is calculated by mass percentage. The prepared preparations were sealed in 10ml ampoules, and 2 sealed bottles of each agent were stored in a refrigerator at 0°C and an oven at 54°C for 14 days, and the content was analyzed at the end of the day to obtain the decomposition rate. The results are shown in Table 1.

Embodiment 2

[0034] According to the formula of Example 2 in Table 1, first add d-limonene in the preparation kettle, then add spirodiclofen, stir and dissolve completely for about 20 minutes, then add emulsifier and continue stirring for about 10 minutes, and continue stirring for about 10 minutes after making up with water. A homogeneous and transparent liquid was obtained in 15 minutes, which was prepared into 5% spirodiclofen microemulsion. The prepared preparations were sealed in 10ml ampoules, and 2 sealed bottles of each agent were stored in a refrigerator at 0°C and an oven at 54°C for 14 days, and the content was analyzed at the end of the day to obtain the decomposition rate. The results are shown in Table 1.

Embodiment 3

[0038] According to the formula of Example 3 in Table 1, first add d-limonene in the preparation kettle, then add spirodiclofen, stir and dissolve completely for about 20 minutes, then add emulsifier and continue to stir evenly for about 10 minutes to complete the preparation of the oil phase. Add water into the mixing tank, and slowly add the oil phase under stirring, so that the oil phase is dispersed in the water phase to form a milky white water emulsion, add antifreeze and stir evenly to prepare a 5% spirodiclofen water emulsion. The prepared preparations were sealed in 10ml ampoules, and 2 sealed bottles of each agent were stored in a refrigerator at 0°C and an oven at 54°C for 14 days, and the content was analyzed at the end of the day to obtain the decomposition rate. The results are shown in Table 1.

Abstract

The invention provides a synergic acaricide which contains an effective amount of spiromesifen, an effective amount of a solvent capable of dissolving the spiromesifen and an effective amount of an emulsifier, and the solvent contains d-hesperidene at least. The synergic acaricide makes use of dissolubility characteristic of stronger dissolving capacity of the d-hesperidene, takes the d-hesperidene as the solvent of the spiromesifen to replace an aromatic solvent with high toxicity and without environmental protection, thus reducing pollution of the acaricide to the environment.In addition, the d-hesperidene as the solvent of the spiromesifen plays functions of dissolving and breaking a waxiness layer on a surface of a destructive acarid body, allows the acaricide to infiltrate into the acarid body more easily and increases quick availability of the spiromesifen, thus improving acarid killing effect. Moreover, the synergic acaricide can be processed to emulsifiable solution, micellar emulsion, aqueous emulsion formulations and the like dosage forms.

Description

technical field [0001] The invention belongs to the field of pesticides, in particular to a synergistic acaricide. Background technique [0002] Spirodiclofen is a tetronic acid acaricide (tetronic acid), chemical name: 3-(2,4-dichlorophenyl)-2-oxo-1-oxaspiro[4,5]-decane- 3-en4-yl-2,2-dimethylbutyl ester; Molecular formula: C 21 h 24 C 12 o 4 ; Relative molecular weight: 411.32. Spirodiclofen has the following characteristics: [0003] 1. The mechanism of action is unique: it mainly inhibits the fat synthesis in harmful mites. It has no cross-resistance with existing acaricides, and is suitable for the prevention and treatment of harmful mites that are resistant to existing acaricides. [0004] 2. Wide spectrum of killing acarids and strong adaptability. Spirodifen has a good control effect on spider mite, yellow spider, rust lice, tea yellow mite, cinnabarinus and two-spotted spider mite, etc. Control of mite infestation of family crops. In addition, spirodiclofen ...
