Problems solved by technology

[0006] Acetate, has contact and stomach poisoning effects, no systemic and osmotic conduction effects, effective for adults and nymphs, poor ovicidal effect
[0007] The compounding of different types of acaricides can improve the control effect, expand the scope of control, and save the cost of medication. At present, there is no known combination of ethifenapyr, pyrimaben, spiromethifen, hexythiazox, and clofenac. Related reports on mixing and controlling pest mites

Embodiment 1

[0035] Example 1 (30% ethifenapyr-pyrimidin suspension concentrate)

[0036] Raw material formula: by mass percentage

[0037] Active Ingredient Ethofenazole 25%

[0038] Active Ingredient Pyrimiden 5%

[0039] NNO 3%

[0040] BY110 2%

[0041] APE-1 2%

[0042] Xanthan Gum 0.15%

[0043] Propylene Glycol 1%

[0044] Octanol 0.05%

[0045] water balance.

[0046] The preparation method is as follows:

[0047] According to the formula, the components are weighed in proportion, added to a ball mill and milled for 30 minutes, filtered, pumped into a dispersion tank for 3 minutes at high speed and then fully ground by a sand mill to control the particle diameter of the solid component within 2 microns. After grinding Stir evenly to obtain the suspension concentrate product.

Embodiment 2

[0048] Example 2 (30% Ethafen-Spirofen EC)

[0049] Raw material formula: by mass percentage

[0050] Active Ingredient Etofen Fenox 5%

[0051] Active ingredient Spiromethin 25%

[0052] Xylene 20%

[0053] DMF 2%

[0054] Anhydrous Calcium Salt 5%

[0055] Tween 80 5%

[0056] Carbon tetrachloride balance.

[0057] Preparation method: fully dissolve the active component in xylene, stir well, add anhydrous calcium salt and Tween 80, then use solvent DMF to adjust the content, and use carbon tetrachloride to adjust the balance.

Embodiment 3

[0058] Example 3 (30% ethifenac·hexythiazox water-dispersible granules)

[0059] Active Ingredient Ethofenazole 25%

Abstract

The invention discloses an acaricide composition containing SYP-9625 and fluacrypyrim, spiromesifen, hexythiarizonaox or propargite, and a common preparation form is prepared from the effective component of SYP-9625 and fluacrypyrim, spiromesifen, hexythiarizonaox or propargite and a proper agricultural additive. The acaricide composition has remarkable preventing and curing effect on cotton red spider mite and other harmful mites on crops, the synergistic effect between the two medicaments is obvious, drug dosage can be reduced, the drug resistance of a single medicament can be delayed, and the acaricide composition is economical, efficient and environmental friendly.

Description

technical field [0001] The invention belongs to the field of chemical control of harmful mites, and in particular relates to an acaricide composition and an application method thereof. Background technique [0002] Ethafenac, chemical name: (z)-2-(4-tert-butylphenyl)-2-cyano-1-(1-ethyl-3-methylpyrazol-5-yl)vinyl -2,2-Dimethyl propionate is a compound with high acaricidal activity discovered by Shenyang Sinochem Pesticide Chemical Research and Development Co., Ltd. after the transformation of pyrafen-diclofen as the lead compound. It is effective against bees, birds, fish, and silkworms. Low toxicity, effective in preventing and controlling citrus spider mites, apple spider mites, cotton spider mites and vegetable spider mites. [0003] Pyrimiden, a low-toxic acaricide, is a mitochondrial respiration inhibitor that blocks the electron transfer between cytochrome b and c1. It is mainly used to prevent and control various mites in fruit trees such as apples, citrus, and pears....
