Embodiment 1

[0058] Example 1: 10% etoxazole · acequinone emulsifiable concentrate

[0059] 93% etoxazole technical 5.38g

[0060] 96.8% acequinone technical 5.17g

[0061] Tristyrylphenol polyoxyethylene polyoxypropylene ether (emulsifier) ​​5g

[0062] Calcium dodecylbenzenesulfonate (emulsifier) ​​5g

[0063] Xylene (solvent) was made up to 100 g.

[0064] Add active ingredients, emulsifiers and solvents into a mixing kettle according to the formula, and stir evenly to prepare 10% etoxazole·methaquinone emulsifiable concentrate.

[0065] This example is applied to Shenzhen Longgang vegetable farm to control cucumber two-spotted spider mite. The dosage and control effect are shown in Table 3. It can be seen from Table 3 that the control effect of the compound agent on Tetranychus urticae 2 days after treatment is significantly higher than that of etoxazole alone, indicating that the compound agent has greatly improved the quick-acting property of etoxazole; The control effect of ace...

Embodiment 2

[0068] Embodiment 2: 22% etoxazole · acequinone suspension concentrate

[0069] 93% etoxazole technical 2.15g

[0070] 96.8% acequinone technical 20.66g

[0071] Sodium methylnaphthalenesulfonate formaldehyde condensate (wetting and dispersing agent) 5 grams

[0072] Xanthan gum (thickener) 1 g

[0073] Bentonite (thickener) 1g

[0074] Glycerin (antifreeze) 4 grams

[0075] Water to make up to 100g.

[0076] Active components, dispersant, wetting agent, water and other components are uniformly mixed according to the ratio of the formula, and ground to obtain a 22% methacazole·methaquinone suspension concentrate.

[0077] This example is applied to the prevention and control of Panonychus citrus in Yunfu, Guangdong, and the dosage and control effect are shown in Table 4. It can be seen from Table 4 that the overall control effect of the compound agent on Panonychus citrus is higher than that of the two single agents, and it has obvious advantages compared with the conven...

Embodiment 3

[0080] Embodiment 3: 11% etoxazole · acequinone aqueous emulsion

[0081] 93% etoxazole technical 10.75g

[0082] 96.8% acequinone technical 1.03g

[0083] N-Methylpyrrolidone (solvent) 10g

[0084] Tristyrylphenol ethoxylate phosphate (emulsifier) ​​4 g

[0085] Propylene glycol (antifreeze) 4 grams

[0086] Polydimethylsiloxane (defoamer) 0.3g

[0087] water to 100g

[0088] Add the original medicine, solvent and emulsifier together to dissolve into a uniform oil phase; mix antifreeze and defoamer to obtain a water phase; mix the oil phase with the water phase under high-speed stirring to obtain 11% ethyl alcohol Facazole · Acarquinone Water Emulsion.

[0089] This example is applied to the prevention and treatment of litchi gall mite, and the dosage and control effect are shown in Table 5. It can be seen from Table 5 that the control effect of the compound agent on litchi gall mite 2 days after treatment is better than that of etoxazole and acequinone alone; the cont...

Abstract

The invention discloses a synergistic mite killing composition. The composition is characterized in that active ingredients of the composition are etoxazole and acequinocyl. The mite killing composition has a good prevention and control effect on harmful phytophagous mites and an obvious prevention and control effect on the mites with resistance.

Description

technical field [0001] The invention relates to an acaricidal composition, in particular to an acaricidal composition containing etoxazole and acequinone. Background technique [0002] Acarids belong to the class Arthropoda. Herbivorous mites mainly include spider mites, panonychia, gall mites, rust mites, etc., which are one of the important pest species that endanger agricultural production. The pest mites are small and do great harm. Usually, the plants infested by the pest mites suffer from chlorosis of leaves and peeling of fruits. Pest mites reproduce quickly, have a large population density, and have obvious overlapping generations, making it easy to develop resistance to pesticides. At present, a variety of mites have developed strong resistance to conventional pesticides (such as: Yuan Minglong, Liu Yonghua, etc. Research progress on the resistance of Panonychus citrus, "Food Security and Plant Protection Science and Technology Innovation", 2009; Li Ruijuan, Wang ...
