[0003] Azocyclotin, with the CAS registration number 41083-11-8 and the chemical name of tricyclohexyl(1,2,4-triazol-1-yl)stannane, is a broad-spectrum systemic acaricide with a wide acaricidal spectrum, high activity, and safety for crops. It can control various harmful mites such as Panonychus citri, Tetranychus urticae, and Phyllocoptruta oleivora on crops such as citrus, hawthorn, apple, grape, and eggplant, and has good control effects on nymphs, adults, and eggs.

[0004] Fenbutatin oxide, with the CAS registration number 13356-08-6 and the chemical name of bis[tris(2-methyl-2-phenylpropyl)tin]oxide, is an efficient temperature-sensitive acaricide. It is mainly used for controlling mite damage on citrus, apple, grape, tea, solanaceous plants, and ornamental flowers. It can effectively kill citrus red spiders, Tetranychus urticae, Phyllocoptruta oleivora, Brevipalpus obovatus, and Panonychus citri, etc., and has the characteristics of high efficiency, low toxicity, safety, long residual period, and no resistance occurrence.

[0005] Mites are a type of harmful organisms that are relatively difficult to control in agricultural production. Especially due to the improper use of pesticides, Tetranychus urticae has risen from a minor pest to a major pest, showing a trend of increasing year by year in China.

[0006] Mixing or rotating the use of acaricides with different action mechanisms is an important means to delay the resistance of harmful mites and its management, and at the same time has the effects of reducing toxicity and cost. The compound agent with synergistic effect can not only reduce the dosage of pesticides, but also enhance the control effect, and can further delay the resistance of harmful mites. Therefore, the applicant compounded sulfiflumin with either azocyclotin or fenbutatin oxide to develop a highly efficient compound acaricide with multiple action mechanisms, provide a theoretical basis for the management of mite resistance, and further improve the control effect of harmful mites.

[0063] Biological test material: Apple red spider (Panonychus ulmi (Koch)).

[0064] Test agents: sulfiflumin technical, triazotin technical, fenbutatin technical.

[0065] Experimental preparation: Select female adult mites with the same physiological state raised indoors. Cut the double-sided tape into 2 cm long pieces and stick them on one end of the slide. Then select healthy mites and stick their backs on the double-sided tape. Put 30 mites per slide and place them in a container with a wet sponge pad, cover it with a lid, and place it at (25±1)℃. Perform microscopic examination after 2 hours, remove dead and injured individuals, and make up 30 mites per slide.

[0066] Pharmaceutical preparation: The original drug is formulated into a mother liquor with an organic solvent, and then formulated into 5 series of mass concentrations with a 0.1% Tween-80 aqueous solution.

[0067] Pharmaceutical treatment: Immerse the glass slide in the medicinal liquid, gently shake it for 5 s and then take it out, absorb the excess medicinal liquid with blotting paper, place it in a white disk padded with a moist sponge, and cover it with a plastic film with good light transmittance.

[0068] Each treatment is repeated 4 times, and a treatment without the pharmaceutical (containing all organic solvents and emulsifiers) is set as a blank control.

[0069] Rearing and observation: Place the container containing the treated test insects under the conditions of a temperature of (25 ± 1) °C and a photoperiod of L:D = (16:8) h for rearing and observation.

[0070] Inspection: Check the death situation of the test insects 48 h after treatment, and record the total number of insects and the number of dead insects respectively.

[0071] Calculation method:

[0072] According to the investigation data, calculate the mortality of each treatment. Calculate according to the following formula:

[0073]

[0074] In the formula:

[0075] P —— Mortality, unit: percentage (%);

[0076] K —— Represents the number of dead insects, unit: head;

[0077] N —— Represents the total number of treated insects, unit: head.

[0078]

[0079] In the formula:

[0080] P 1 —— Corrected mortality, unit: percentage (%);

[0081] P t —— Treatment mortality, unit: percentage (%);

[0082] P 0 —— Blank control mortality, unit: percentage (%).

[0083] If the control mortality < 5%, no correction is required; if the control mortality is between 5% and 20%, correction should be carried out according to formula (2); if the control mortality > 20%, the test needs to be redone.

[0084] The co-toxicity coefficient (CTC value) of the mixture is calculated according to Equations (3), (4), and (5):

[0085]

[0086] Wherein:

[0087] ATI—the measured toxicity index of the mixture;

[0088] S—the LC 50 of the standard acaricide, with the unit of milligram per liter (mg / L);

[0089] M—the LC 50 of the mixture, with the unit of milligram per liter (mg / L).

[0090] TTI = TI A × P A + TI B × P B

[0091] Wherein:

[0092] TTI—the theoretical toxicity index of the mixture;

[0093] TI A —the toxicity index of pesticide A;

[0094] P A —the percentage content of pesticide A in the mixture, with the unit of percentage (%);

[0095] TI B —the toxicity index of pesticide B;

[0096] P B —the percentage content of pesticide B in the mixture, with the unit of percentage (%).

[0097]

[0098] Wherein:

[0099] CTC—the co-toxicity coefficient;

[0100] ATI—the measured toxicity index of the mixture;

[0101] TTI—the theoretical toxicity index of the mixture.

[0102] When the co-toxicity coefficient CTC of the compounding ≥ 120, it shows a synergistic effect; when CTC ≤ 80, it shows an antagonistic effect; when 80 < CTC < 120, it shows an additive effect. The results of the indoor toxicity test are shown in the following table:
