Embodiment 1

[0018] Example 1: 21% fenazaquin · profenofos emulsifiable concentrate

[0019] Fenazazafen 20.20g

[0020] Profenofos 1.12g

[0021] Calcium dodecylbenzenesulfonate (emulsifier) ​​5g

[0022] Phenylphenol polyoxyethylene ether (emulsifier) ​​5g

[0023] Xylene (solvent) make up to 100g

[0024] The active ingredients, the original medicine, the emulsifier and the solvent, etc., are sequentially added to the mixing tank according to the ratio of the formula, and stirred evenly to obtain 21% fenazazafen·profenofos emulsifiable concentrate. (The mass ratio of fenazaquin and profenofos is 20:1)

[0025] Profenofos in this example can be replaced by chlorpyrifos or methidon to form a new example.

Embodiment 2

[0026] Example 2: 18% fenazazafen · methapon emulsifiable concentrate

[0027] Fenazazafen 16.16g

[0028] Phytophos 2.11g

[0029] Calcium dodecylbenzenesulfonate (emulsifier) ​​5g

[0030] Phenylphenol polyoxyethylene ether (emulsifier) ​​5g

[0031] Xylene (solvent) make up to 100g

[0032] Add the original drug, emulsifier and solvent into the mixing tank in sequence according to the ratio of the formula, and stir evenly to obtain 18% fenazaquin · methapone emulsifiable concentrate. (The mass ratio of fenazazafen and methapon is 8:1)

[0033] The profenofos in this embodiment can be replaced by profenofos or chlorpyrifos to form a new embodiment.

Embodiment 3

[0034] Example 3: 12% fenazaquin · chlorpyrifos EC

[0035] Fenazazafen 10.10g

[0036] Chlorpyrifos 2.11g

[0037] Calcium dodecylbenzenesulfonate (emulsifier) ​​5g

[0038] Phenylphenol polyoxyethylene ether (emulsifier) ​​5g

[0039] Xylene (solvent) make up to 100g

[0040] Add the original drug, emulsifier and solvent into the mixing tank in sequence according to the ratio of the formula, and stir evenly to obtain 12% fenazaquin · chlorpyrifos emulsifiable concentrate. (The mass ratio of fenazaquin and chlorpyrifos is 5:1)

[0041] Chlorpyrifos in this embodiment can be replaced by profenofos and methapon to form a new embodiment.

Abstract

The invention relates to a mite-killing composition comprising the effective component of fenazaquin and the other active component, wherein the other active component is any one of organophosphorus pesticide of profenofos, chlopyrifos and supracide, and the proportion of the fenazaquin and the organophosphorus pesticide in parts by mass is 20:1-1:60. The fenazaquin and the organophosphorus pesticide of the profenofos, the chlopyrifos and the supracide are compounded, which has an obvious synergistic action, good quick-acting property and long acting period, and can delay the generation of thedrug resistance of harmful mites. The composition can be used for preventing and treating the harmful mites on crops and is especially suitable for preventing and treating full-claw mites, tetranychus telarius and tetranychus urticae.

Description

technical field [0001] The invention relates to a pesticide composition, specifically an acaricidal composition containing fenazaquin and having a synergistic effect, and the application of the composition in agriculture. Background technique [0002] Fenazaquin: English common name Fenazaquin, chemical name: 4-tert-butylphenethylquinazoline, molecular formula: C 20 h 22 N 20 ; The structural formula is: [0003] [0004] The drug is a quinoline acaricide, which acts on the mitochondria and chromosome 1 of insect cells by contact killing, occupying the junction of coenzyme Q. It has a good control effect on citrus and apple spider mite, has a long lasting effect, and is safe to natural enemies. No cross-resistance with existing acaricides, especially suitable for controlling harmful mites resistant to existing acaricides. However, the cost of this acaricide is relatively high, and long-term use of a single agent is prone to resistance. [0005] Profenofos: English c...
